Technical Field

The present disclosure relates to an apparatus and a window panel laminating method for laminating a panel to a window, and more particularly, to an apparatus and a method for laminating a panel to a window having an at least partially curved portion.

Background

Recently, with the push out of display devices having various designs, a curved surface type display device capable of further improving the degree of immersion of a user is being actively developed. Such curved type display devices may be applied (e.g., smart phones, tablet computers, TVs, etc.), have many advantages in design due to excellent space availability and aesthetic sense, and have been actively researched in various application fields.

Generally, a curved type display device is used in its entirety in many cases, and in each case, a flexible panel is attached to a cover window (cover window) having an at least partially curved portion. Accordingly, a number of techniques have been developed, each of which may be utilized to attach a flexible panel to a cover window having an at least partially curved portion.

However, although the cover window having the at least partially bent portion and the flexible panel are attached to each other, it is difficult to control the degree of deformation of the flexible panel. Further, since it is difficult to apply uniform pressure to all surfaces of the cover window, the following problems occur: it is very difficult to attach the flexible panel without generating bubbles on the curved surface area and its boundary surface.

In particular, when a curved region of the cover window exhibits a high curvature, the radius of curvature of such curved region decreases, and the space in which the panel can be pressed to the cover window may be very narrow. Further, the pressing force is not sufficiently transmitted to the panel in the curved surface region, and therefore, there is a problem that the cover window is not brought into complete close contact with the flexible panel so that a defect such as a bubble is generated between the cover window and the panel.

Therefore, there is a need for a technique that can laminate a flexible panel without defects, even to various windows having a curved shape (the curved shape includes a curved surface having a high curvature).

Detailed Description

Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings. This invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the description, like reference numerals refer to like configurations, which may be partially exaggerated in order to clearly illustrate exemplary embodiments, and like elements are referred to by like reference numerals in the drawings.

Fig. 1 is a cross-sectional view illustrating a window panel laminating apparatus according to an exemplary embodiment.

Referring to fig. 1, a window panel laminating apparatus according to an exemplary embodiment is shown at least by way of a cross-sectional view thereof.

Referring to fig. 1, a window panel laminating apparatus according to an exemplary embodiment may include: a window attachment member 200 for attaching the cover window 20 having an at least partially curved portion; a panel support member 100 facing the window attachment member 200 and supporting the panel 10; and a gap adjusting member 500 for adjusting a gap between the window attachment member 200 and the panel support member 100.

Further, the panel supporting member 100 may include: a body member 110 provided with a flow channel 112 through which a fluid F may be supplied; an elastic pressing member 130 provided on the body member 110 and transmitting elastic force to the panel 10; and a diaphragm 120 surrounding the body member 110 and expanded by the fluid F supplied through the flow channel 112 so that the panel supporting member 100 may press the panel against the cover window 20.

A cover window 20 having an at least partially curved portion may be attached to the window attachment member 200. Here, the cover window 20 should be transparent because the cover window should be able to function to protect the screen part of the display panel 10 from external influences and to transmit the display screen. Accordingly, glass or plastic (e.g., CPI or colorless polyimide) may be used, although exemplary embodiments are not particularly limited thereto. At this time, the panel may be a flexible display panel 10 such that the panel may be laminated to a cover window 20 having an at least partially curved portion

Further, the cover window 20 may be a curved shape type window 20 having a shape curved with respect to one axis passing through a central portion of the cover window 20. Here, the curved shape may include all curved or folded shapes. At this time, the cover window 20 may be attached to the window attachment member 200 such that the attachment surface of the cover window 20 faces the panel 10. At this time, in the window attachment member 200, a surface facing the suction surface of the cover window 20 using vacuum suction may be temporarily fixed.

The panel support member 100 may be disposed to face the window attachment member 200 and support the panel 10.

At this time, the panel support member 100 may support the panel 10 such that the attachment surface of the panel 10 faces the cover window 20 by supporting the surface facing the attachment surface of the panel 10. At this time, the gap adjustment member 500 may adjust the gap between the window attachment member 200 and the panel support member 100 by moving at least one of the window attachment member 200 and the panel support member 100. Accordingly, the attachment of the cover window 20 and the panel 10 may be in contact with each other by adjusting the gap between the window attachment member 200 to which the cover window 20 is attached and the panel support member 100 supporting the panel 10, and the cover window 20 and the panel 10 may be laminated by what will be described below.

At this time, the exposed surface of the cover window 20 or the panel 10 may be provided with an adhesive surface composed of an adhesive material for laminating the cover window 20 and the panel 10. At this time, the adhesive surface may be adhered by an Optically Clear Resin (OCR), an Optically Clear Adhesive (OCA), or the like. Such an adhesive surface may be formed on, for example, exposed surfaces facing each other on the cover window 20 and/or the panel 10 and wait in a state of being protected by foreign paper (hetero paper) or the like before lamination, and the adhesive surface may be exposed when the foreign paper is removed for lamination. The OCR or OCA may have a light transmittance of at least about 90% due to the optical adhesive material, and may prevent an image quality from being unclear due to light reflection, but the exemplary embodiments are not limited thereto.

Fig. 2 is a view illustrating a state in which an elastic pressing member according to an exemplary embodiment presses a panel, and fig. 3 is a view illustrating a state in which a diaphragm according to an exemplary embodiment presses a panel.

Referring to fig. 2 and 3, in a window panel laminating apparatus according to an exemplary embodiment, a panel supporting member 100 may include: a body member 110 provided with a flow passage 112 to which a fluid F can be supplied; an elastic pressing member 130 provided on the body member 110 and transmitting elastic force to the panel 10; and a diaphragm 120 surrounding the body member 110 and expanded by the fluid F supplied through the flow channel 112, and may press the panel against the cover window 20.

At this time, the panel 10 may be partially pressed against the cover window 20 by the elastic pressing member 130, and secondarily pressed by the diaphragm 120.

The diaphragm 120 may be an elastic membrane that may be provided in a shape including a space capable of containing the fluid F, and the diaphragm 120 may be expandable when the fluid F is supplied to the space. Further, the adhesive surface of the panel 10 may be pressed to the adhesive surface of the cover window 20 by fixing the panel 10 to the outer surface of the diaphragm 120. In particular, when the diaphragm 120 capable of adjusting its degree of expansion is used, the flexible panel 10 can be pressed to the cover window 20 exhibiting various shapes and curvatures as well without variation in equipment. Here, the diaphragm 120 may be composed of, for example, heat-curable silicone, such as High Consistency Rubber (HCR), and expanded by the fluid F, and may be used as long as it can be restored to an original shape by recovering the fluid F, and the exemplary embodiment is not limited thereto.

At this time, in order to improve the accuracy of pressurization of the panel 10, a portion of the panel 10 may be preferentially pressed against the cover window 20 by providing the elastic pressing member 130 on the upper side (including all the inside and outside of the diaphragm 120) on the diaphragm 120. Accordingly, since the cover window 20 and the panel 10 are partially laminated when the entire surface of the panel 10 is pressed, the panel 10 may not be shaken, a uniform pressing force may be provided on the entire surface, and accuracy may be improved. Further, when a portion of the panel 10 is laminated on the curved surface region of the cover window 20 by using the elastic pressing member 130, the curved surface region is preferentially pressed, and therefore, incomplete attachment of the panel 10 may be prevented in the curved surface region, and the accuracy of lamination may be improved.

Here, the elastic pressing member 130 may press a portion of the panel 10 by the gap adjustment member 500. At this time, in order to prevent the panel 10 from being damaged due to a sudden impact, the elastic pressing member 130, which is made of a material capable of alleviating the impact, may be used to press the panel 10 while transmitting elastic force to the panel 10. Accordingly, the elastic pressing member 130 may be provided by using an elastically deformable material such as silicone rubber, but exemplary embodiments are not limited thereto.

Meanwhile, the diaphragm 120 is an expandable elastic film such that the elastic pressing member 130 is located on the diaphragm 120, and the body member 110, which is composed of a material exhibiting higher hardness than the diaphragm 120, may support the elastic pressing member 130 in order to press the panel 10. Accordingly, the elastic pressing member 130 may be fixed to the body member 110, and the elastic pressing member 130 may press the panel 10 against the cover window 20.

At this time, the body member 110 is located inside the diaphragm 120, and thus, the body member 110 may include the flow channel 112 capable of supplying the fluid F into the diaphragm 120. Accordingly, the diaphragm 120 may be expanded by the supplied fluid F, and may press the panel 10 against the cover window 20.

Accordingly, the elastic pressing member 130 provided on the body member 110 may first press the panel 10 against the cover window 20. Further, since the fluid F is supplied from the flow channel 112 provided to the diaphragm 120, the panel 10 fixed to the panel support member 100 may be secondarily pressed against the cover window 20. Thus, precise lamination can be provided by the sequentially provided pressing.

The upper surface of the elastic pressing member 130 may be disposed at a position corresponding to a region having a portion that is at least partially curved and be configured of a curved surface.

The elastic pressing member 130 may have an upper portion configured by a curved surface so as to stably transmit elastic force to the panel 10 while being elastically deformed. In particular, when such a curved surface is provided to the cover window 20 so as to correspond to the shape of a region having a portion that is at least partially curved, the elastic pressing member 130 may laminate the curved surface region of the cover window 20 and then laminate the remaining flat surface when pressing the panel 10. Therefore, a phenomenon that the gap between the panel 10 and the cover window 20 may not be brought into close contact with each other and floated due to incomplete pressurization may be prevented, and precise lamination may be provided.

Meanwhile, the cover window 20 may be bent with respect to an axis passing through a central portion of the cover window 20.

In general, many curved type display devices have shapes, each of which generally has a flat central portion and a peripheral edge of which only a portion is curved, and a technology capable of laminating a flexible panel to a cover window having such a shape has been developed. However, as the curvature of the curved surface region increases, the radius of curvature decreases. Therefore, in order to laminate the panel 10 to the cover window 20 forming a curvature in a narrow region, a curved region having a smaller width and a larger distance may be pressed. At this time, the region may not be sufficiently pressed only with the conventional technique, the cover window and the panel may not be completely laminated, and a floating phenomenon may occur. Thus, when the area is pressed with a large pressure in order to provide sufficient pressing, the pressed panel may also be damaged. Therefore, special techniques that can provide sufficient pressurization to the narrow curved region may be required.

The curved region of the cover window 20 according to an exemplary embodiment may be provided in a shape that is curved with respect to one axis, for example, so as to exhibit a higher curvature. Furthermore, the screen member may be disposed multilaterally over the entire curved area connecting two planes facing each other in this particular shape.

At this time, the curved surface region may exhibit a high curvature so as to connect two planes opposite to each other, and the technique of laminating the cover window exhibiting a special curved surface has a great advantage: the techniques may also be used later to develop display devices having various designs.

However, in the curved region that may be disposed between the planes with a small width, the panel 10 may not be completely pressed against the cover window 20, and a floating phenomenon and bubbles may occur between the cover window 20 and the panel 10. Therefore, more precise lamination techniques may be required.

Fig. 4 is a view illustrating an operation of an elastic pressing member according to an exemplary embodiment, fig. 4 (a) illustrates the elastic pressing member before a panel is pressed, and fig. 4 (b) illustrates the elastic pressing member when the panel is pressed.

Referring to fig. 4, in the window panel laminating apparatus according to an exemplary embodiment, the elastic pressing member may include: an elastic body member 131 made of an elastic material; and a rigid body component 132 at least partially surrounded by the elastomeric component 131 and composed of a material having a higher hardness than the elastomeric component 131.

Thus, when the cover window 20 has a special shape in which a narrow curved surface is formed, more precise pressurization may need to be applied to the curved surface region of the cover window 20, and the elastic pressing member 130 should be able to press an accurate position so that the curved surface region can be precisely pressed. However, considering that the panel 10 is not damaged, the elastic pressing member 130 may exhibit a low elastic modulus, and when the elastic pressing member 130 presses the panel 10, a curved surface of the elastic pressing member 130 may be bent while pressing. Therefore, the elastic pressing member 130 may be deformed to such an extent that it cannot cope with the curved shape of the cover window 20. Further, the elastic pressing member 130 may not be able to press an accurate position when inclined, and may not completely press the curved surface region of the cover window 20.

Therefore, the elastic pressing member 130 may include: an elastically deformable elastic body member 131; and a rigid body part 132 that reinforces the strength of the elastic body part 131 so that the elastic body part 131 is not excessively deformed and is composed of a hard material so as to fix the position of the elastic body part 131. Accordingly, the elastic body member 130 can press the panel 10 without damaging the panel 10 while being elastically deformed. Further, the elastic pressing member 130 can be prevented from failing to press an accurate position due to excessive deformation or inclination of its shape, and can accurately press an accurate position in a curved surface region.

Meanwhile, shore hardness (shore a) represents hardness by the magnitude of rebound at the time of collision of one object with another object, and the magnitude of rebound due to collision corresponds to the work consumed by elastic deformation of the colliding object.

Accordingly, the elastic body part 131 may optimally have a shore hardness (shore a) of about 20 to 40, and the elastic pressing part 130 may mitigate an abrupt impact when the elastic pressing part 130 presses the panel 10. Accordingly, damage to the panel 10 may be prevented and the panel 10 may be pressed while an elastic force may be transmitted by a restoring force to be restored to an original shape after being at least partially pressed. Here, silicone rubber, such as Liquid Silicone Rubber (LSR), may be used for the elastomer member 131, but exemplary embodiments are not limited thereto.

The elastic pressing member 130 may be excessively hard when exhibiting a shore hardness (shore a) exceeding about 40, and the elastic pressing member 130 may be hardly deformed when a gap between the window attachment member 200 and the panel support member 100 is reduced and the elastic pressing member 130 is at least partially pressed. Therefore, a stronger pressure may be required to press the panel 10, the elastic pressing member 130 may be further pressed by the gap adjusting member 500, and the panel 10 may be damaged when the stronger pressure is applied to the panel 10.

At this time, when the shore hardness (shore a) of the elastic pressing member 130 is less than about 20, the elastic pressing member 130 may be too soft, may not be easily restored to an original shape after being deformed, and may not exhibit an elastic restoring force for pressing the panel 10.

Fig. 5 is a view illustrating operations of an elastic pressing member and a body member according to an exemplary embodiment.

Referring to fig. 5, the elastic pressing member 130 extends in one direction, and the rigid body member 132 may have an axial shape extending parallel to the one direction.

Such a rigid body part 132 may be provided in a shaft shape considering that the shape of the elastic pressing part 130 extends in one direction, and the shaft may be provided at a position corresponding to the bending region of the cover window 20. Therefore, even when the elastic pressing member 130 presses the panel in a narrow area, a position pressed by the elastic pressing member 130 can be accurately provided.

At this time, the rigid body part 132 should exhibit the shaft shape and should reinforce the strength of the rigid body part 131, and therefore, the rigid body part 131 should have high strength and the rigid body part can maintain high strength even when it is manufactured in a thin shape preferably using bearing steel such as SUJ2 and a material such as SUS 304.

Here, the body part 110 may further include fastening parts 111 fastened to both ends of the rigid body part 132 and fixing the elastic pressing part 130.

In order to fix the position of the elastic pressing member 130, a method of attaching the elastic pressing member 130 to the upper surface of the body member 110, for example, may be used, but in this case, a problem may be caused in that the fluid F may not be supplied to the upper surface of the body member 110. Accordingly, both ends of the shaft-shaped rigid body part 132 are fastened to the body part 110, and thus, the position of the elastic pressing part 130 can be fixed, and accurate pressurization can be provided.

At this time, fastening parts 111 having shapes corresponding to both ends of the rigid body part 132 may be provided at the upper end of the body part 110 as shown in fig. 5, for example. Further, when such a fastening part 111' is further provided to an assembly attachable/detachable to/from the body part 110, it is convenient to replace the elastic pressing part 130 with a new assembly when the life span of the elastic pressing part 130 including the elastic body part 131 and the rigid body part 132 is reached.

Meanwhile, the central axis of the rigid body part 132 may be disposed to be positioned below half the height of the elastic pressing part 130.

When the position where the rigid body part 132 is provided is set too high, the deformation of the elastic body part 131 may be disturbed, the elastic body part 131 may not be elastically deformed, and the elastic force for pressing the panel 10 may not be sufficiently transmitted. Further, when the position is set too low, the elastic body member 131 may be excessively deformed, the reinforcing effect due to the rigid body member 132 may not be exhibited, and an error due to the inclination may be caused.

Therefore, in consideration of the advantage, the position of the rigid body 132 may be set such that the central axis of the shaft is preferably positioned below half the total height of the elastic pressing member 130. Accordingly, the rigid body 132 may support the position of the elastic pressing member 130, may reinforce the elastic body member 131, and may provide accurate lamination.

Meanwhile, such an elastic pressing member 130 may be provided with: a curved surface part forming a curved surface on an upper part thereof; and a linear member having a shape with a constant thickness to support the curved member and extending in a height direction thereof on a lower portion thereof, and the rigid body member 132 may be provided to the linear member.

At this time, when the rigid body part 132 is positioned at the curved surface part, the elastic deformation of the elastic pressing part 130 may be disturbed, and the curved surface part may not be easily structurally supported. Accordingly, the rigid body part 132 is positioned on the linear part of the elastic pressing part 130, and thus the position of the curved surface part can be supported, and the curved surface of the elastic pressing part 130 is bent, and thus an error in the shape of the curved surface of the cover window can be prevented.

Fig. 6 is a view illustrating a body member according to an exemplary embodiment, (a) of fig. 6 illustrates a state in which an injection port is provided on an upper surface and a side surface, (b) of fig. 6 illustrates a state in which the injection port is provided on the same side surface at different heights, and (c) of fig. 7 illustrates a state in which an upper portion of a diaphragm 120 according to an exemplary embodiment is expanded.

Referring to fig. 6 and 7, in the window panel laminating apparatus according to the exemplary embodiment, a plurality of flow channels 112 may be provided, the body member 110 may further include a plurality of injection ports 113 communicating with the plurality of channels 112, and at least a portion of the plurality of injection ports 113 may be positioned at mutually different positions.

Meanwhile, the body member 110 may include a flow channel 112 capable of supplying the fluid F to the inner surface of the diaphragm 120, and an injection port 113, which is an opening portion of the body member 110, may be provided at an end of the flow channel 112. At this time, the injection ports 113 may be disposed at mutually different heights, and when the fluid F is supplied to the injection ports 113 at mutually different heights, the fluid F may be supplied at mutually different heights. Accordingly, the positions at which the diaphragms 120 are selectively expanded may be set different from each other. For example, after a portion of the upper portion of the diaphragm 120 is pre-expanded, the lower portion or the entire surface of the diaphragm 120 is expanded so that the panel 10 can be accurately laminated to the cover window 20.

Here, a fluid supply part (not shown) for supplying the fluid F to the plurality of injection ports 113 may be further provided, and the fluid supply part (not shown) may sequentially supply the fluid F to the plurality of injection ports 113 according to the height of the injection ports 113.

Further, the body member 110 has a wall shape, and the plurality of injection ports 113 may include: an upper surface ejection port 113 provided on an upper surface of the body member 110; and a side surface injection port 113 provided to a side surface of the body member 110.

A plurality of such flow channels 112 may be provided, and the flow channels 112 are provided to each of the injection ports 113 having mutually different heights, and therefore, the injection ports 113 having mutually different heights may be individually controlled.

The ejection port 113 may be formed in the upper surface and the side surface as in (a) of fig. 6, and in the side surface at mutually different heights as in (b) of fig. 6, but it is sufficient as long as the fluid F can be sequentially supplied at mutually different heights, and the shape of the ejection port is not particularly limited thereto.

Here, a fluid supply member (not shown) may be connected to the flow channel 112 and supply the fluid F to the diaphragm 120. For example, the fluid supply part may also be configured as a fluid supply apparatus capable of supplying the fluid F at a constant volume and/or a constant pressure of a hydraulic pump or the like, but the exemplary embodiments are not limited thereto, and thus, the supply pressure of the fluid F may be controlled, and the supply fluid may also be allowed to be recovered.

At this time, in the method of sequentially supplying the fluid F according to the heights of the injection ports 113, for example, the injection ports 113 positioned at mutually different heights may be connected to a fluid supply part (not shown) through mutually different valves (not shown), and the supply of the fluid F to the injection ports 113 having mutually different heights may be individually adjusted. Further, the injection ports 113 positioned at the same height may be adjusted by the same valve (not shown), and the injection of the fluid F may be simultaneously performed at the same height.

Thus, the supply of the fluid F is sequentially controlled according to the height, and thus, the diaphragm 120 above the panel supporting member 100 is previously expanded as in fig. 7, and a portion of the panel 10 may be fixed by first pressing. Further, it is possible to press the lower portion of the panel supporting member 100 or the entire surface of the panel 10 without shaking, and prevent air bubbles from occurring between the cover window 20 and the panel 10, and therefore, lamination of the cover window 20 and the panel 10 can be stably and accurately provided.

If the ejection port 113 is provided on the upper surface of the body member 110, and when the elastic pressing member 130 is brought into direct contact with the upper surface of the body member 110, the fluid F may not be easily ejected from the ejection port 113. Therefore, as illustrated in fig. 5, the elastic pressing member 130 may be disposed on the body member 110 in a spaced shape using the fastening member 111 or the like, but it is sufficient to provide a gap on the body member 110 from the elastic pressing member 130, and the shape is not particularly limited. At this time, in the spaced distance, when the upper ends of the elastic pressing part 130 and the body part 110 are not completely integrated, there may be a slight gap even when the upper ends of the elastic pressing part 130 and the body part 110 are disposed to almost contact each other. Accordingly, the fluid F may be supplied to the gap, and the elastic pressing member 130 and the body member 110 may be regarded as being spaced apart from each other. Accordingly, the fluid F may be supplied from the injection port 113 provided at the upper surface of the body member 110 and expand the upper portion of the diaphragm 120. At this time, the fluid F injected to the upper portion of the diaphragm 120 reaches the elastic pressing member 130, and can be injected more uniformly, and the injection pressure can be reduced. However, the expansion of the diaphragm 120 due to the fluid F is an expansion for further providing pressurization to a portion of the panel 10 after the first pressurization occurs by the elastic pressing member 130, and thus, a pressure sufficient to press a portion of the panel 10 may be provided.

Meanwhile, the upper surface injection port 113 may be formed in a central portion of the body member 110, and the side surface injection port 113 provided to one side surface of the body member 110 may be symmetrically provided with respect to a central portion of an upper portion of the upper surface.

The upper surface injection port 113 may be provided at the upper surface of the body member 110, and since the upper surface injection port 113 is provided at the upper surface of the body member 110 and the side surface injection port 113 is provided at the shape of the side surface, the upper and lower portions of the diaphragm 120 may sequentially expand. At this time, when the upper surface ejection port 113 and the side surface ejection port 113 are each asymmetrically disposed, the diaphragm 120 may expand in an asymmetric shape. Further, when such asymmetric expansion occurs in a state where a portion of the upper side surface of the diaphragm 120 has expanded, a defect such as a bubble may occur due to irregular expansion between the cover window 20 and the panel 10.

Accordingly, the upper surface ejection port 113 may be formed in a central portion of the upper surface of the body member 110, and the side surface ejection port 113 may be provided to one side surface of the body member 110 symmetrically with respect to the central portion. Accordingly, the diaphragm 120 may be uniformly expanded, and the panel 10 may be pressed without bubbles occurring between the cover window 20 and the panel 10.

In addition, the side surface injection port 113 may include: a first side surface ejection port 113 provided to one side surface of the body member 110; and a second injection port 113 provided at a position corresponding to the first side surface injection port 113 on the other side surface facing the one side surface.

Thus, when the side surface injection port 113 provided to the other side surface facing the one side surface is symmetrically provided to the injection port 113 in the opposite surface, the diaphragm 120 can be provided to be further symmetrically expanded. Therefore, the diaphragm 120 can be further uniformly expanded, and the panel 10 can be stably pressed without bubbles occurring between the cover window 20 and the panel 10.

Fig. 8 is a cross-sectional view illustrating a diaphragm according to an exemplary embodiment.

Referring to fig. 8, in the window panel laminating apparatus according to the exemplary embodiment, the thickness of the elastic film constituting the diaphragm 120 may be greater at a lower side of the panel support member 100 than at an upper side.

Meanwhile, in order to firstly expand the upper portion of the diaphragm 120, the injection ports 113 may be provided to have different heights from each other, but provided such that the thickness of the diaphragm 120 is different according to its position and the expansion speed of the diaphragm 120 is different according to its position. Accordingly, the diaphragm 120 may be disposed such that the thickness t2 of the lower portion of the panel support member 100 is greater than the thickness t1 of the upper side of the panel support member 100. Therefore, the deformation of the diaphragm 120 may be easier on the upper side (which indicates a relatively small thickness) of the panel supporting member 100, and may be expanded earlier by a smaller amount of the fluid F. Accordingly, the panel 10 contacting the diaphragm 120 at the upper side of the panel supporting member 100 can be pressed early, and a start point of pressurization is set. Therefore, the panel 10 can be prevented from shaking during pressurization, and stable pressurization can be provided.

Further, when the elastic film having the same thickness is expanded, shaking may occur due to the shape of the elastic film, and when the panel 10 is pressed by irregular expansion, air bubbles may occur in a space where the cover window 20 and the panel 10 are not completely laminated. At this time, when deformation is applied so that the thicknesses of the elastic films can be set different from each other, a shaking phenomenon can be reduced, and the elastic films can be uniformly expanded and can stably press the panel 10.

At this time, the diaphragm 120 may be composed of a material having a higher shore hardness (shore a) than the elastic pressing member 130.

Meanwhile, the diaphragm 120 should be expanded by the fluid F and press the panel 10, and thus, may require a larger deformation than the elastic pressing member 130, and the diaphragm 120 may be composed of a material exhibiting a higher shore hardness (shore a) than the elastic pressing member 130. Accordingly, the diaphragm 120 is expanded by the fluid F, may press the panel 10 against the cover window 20, and may be used while returning to an original shape after the pressurization is completed.

The membrane 120 may optimally exhibit a shore hardness (shore a) of about 50 to 70, be expanded by supplying the fluid F, press the panel 10, and recover the original shape upon recovery of the fluid F. Further, the diaphragm 120 restored to the original shape can thus be used again to press the panel 10.

However, the diaphragm 120 may soften excessively when exhibiting a shore hardness (shore a) below about 50. Therefore, the diaphragm 120 may not easily recover to an original shape after being expanded to press the panel 10, and when the fluid F is recovered after the pressurization is completed, it may not be easy to reuse the diaphragm 120 for the next batch of lamination. Further, when such restoration is not complete, it may be necessary to replace the diaphragm 120 at each lamination.

Further, to have high resiliency, the diaphragm 120 may be over-hardened when having a shore hardness (shore a) higher than about 70. Therefore, by supplying the fluid F, the diaphragm 120 may not be easily expanded, and the fluid F may have to be supplied at a large pressure, and the cover window 20 and the panel 10 may be damaged due to the high pressure.

Meanwhile, a panel fixing member 300 fixing the panel 10 along the outer surface of the panel supporting member 100 may be further provided.

At this time, the panel 10 is further provided with a panel fixing member 300, the panel fixing member 300 may be provided by being adhered to the carrier sheet 30, and the panel fixing member 300 presses the carrier sheet 30 and fixes the panel 10 along the outer surface of the panel supporting member 100.

The panel 10 is supported on the panel supporting member 100, and lamination may be performed. At this time, when the panel fixing member 300 for fixing the panel 10 to the panel supporting member 100 is provided, the panel may be more securely mounted than a case of being simply supported by the panel supporting member 100. However, when the panel 10 is directly fixed to the panel supporting member 100, physical damage may be caused to the display surface of the panel 10.

Therefore, the carrier sheet 30 to which the panel 10 can be temporarily attached may be used to perform such fixing, and the panel 10 may be fixed to the panel fixing member 100 by fixing the carrier sheet to which the panel 10 is attached to the panel supporting member 100 without causing damage to the display surface of the panel 10. Here, for example, a roller may be used for the panel fixing member 300, but the embodiment is not particularly limited thereto as long as it can press the carrier sheet 30 and fix the position thereof.

Meanwhile, the panel fixing member 300 not only fixes the panel 10 and the carrier sheet so as not to be shaken, but also fixes the panel 10 along the outer surface of the panel supporting member 100, and thus, the panel may be disposed to conform to the shape and size of the space formed by the attachment surface of the cover window 20. Therefore, a phenomenon that at least a portion of the panel 10 cannot be inserted into the space can be prevented, the panel 10 can be accurately pressed, and more precise lamination can be provided.

Accordingly, the panel fixing member 300 may fix the panel 10 along the shape of the outer surface of the panel supporting member 100 (the inner surface of the cover window 20). At this time, the clamps may pull both ends of the carrier sheet 30, and the carrier sheet 30 may not wrinkle when the panel 10 is fixed to the panel supporting member 100. Here, it is sufficient in the window panel laminating apparatus of the present disclosure that the clips may fill and fix both ends of the carrier sheet 30 to any bottom surface of the panel supporting member 100 at a height less than the upper end of the panel supporting member 100, and the clips may be regarded as identical insofar as the functions are similar.

At this time, for example, a tacky UV adhesive sheet may be used for the carrier sheet 30, and when the carrier sheet 30 is irradiated with ultraviolet rays after the effect of attaching the panel 10 is completed, the adhesiveness of the carrier sheet 30 may be lost, and the carrier sheet may be removed from the panel 10. Such a carrier sheet 30 is sufficient to temporarily fix the panel 10, and the embodiment is not particularly limited thereto.

Here, with UV irradiation, the cover window 20 is separated from the window attachment member 200, and UV may be emitted to the carrier sheet 30 above the cover window 20. Alternatively, the panel support member 100, the panel 10, and the carrier sheet 30 are separated, and UV may be emitted to the exposed surface of the carrier sheet 30.

Fig. 9 is a flowchart illustrating a window panel laminating method according to another embodiment of the present invention.

Referring to fig. 9, a window panel laminating method according to another exemplary embodiment will be described, and matters overlapping with the above-described portions regarding the window panel laminating apparatus according to the exemplary embodiment will be omitted. A window panel lamination method according to another exemplary embodiment may include: attaching a cover window having an at least partially curved portion (S100); fixing a panel to a panel supporting member including an elastic pressing member for transmitting an elastic force to a cover window and a diaphragm expanded by a fluid (S200); reducing a gap between the window attaching member and the panel supporting member, and primarily pressing at least a portion of the panel against the cover window by the elastic pressing member (S300); supplying a fluid to inflate the diaphragm, again pressing the panel against the cover window (S400); and separating the window attachment member and the panel support member from each other (S500).

A window panel laminating apparatus according to an exemplary embodiment may include: a window attachment member 200 to which the cover window 20 having an at least partially curved portion is attached; a panel support member 100 facing the window attachment member 200; and a gap adjusting member 500 for adjusting a gap between the window attachment member 200 and the panel support member 100.

At this time, the panel supporting member 100 may include: a body member 110, the body member 110 including a flow channel 112 to which a fluid F can be supplied; an elastic pressing member 130 provided on the body member 110 and transmitting elastic force to the panel 10; and a diaphragm 120 surrounding the body member 110 and expanded by the fluid F supplied through the flow channel 112, and the panel support member may press the panel 10 against the cover window 20.

First, a cover window having an at least partially curved portion is attached to a window attachment member (S100). The cover window 20 may be attached to the window attachment member 200 such that the attachment surface of the cover window 20 faces the panel 10, and the window attachment member 200 may be fixed such that the surface thereof facing the suction surface of the cover window 20 is temporarily attached using vacuum suction or the like.

Next, the panel is fixed to the panel supporting member (S200). The panel support member 100 may be disposed to face the window attachment member 200 and support the panel 10. In addition, the panel supporting member 100 may include an elastic pressing member 130 and a diaphragm 120. At this time, the panel support member 100 may support the panel 10 such that the attachment surface of the panel 10 faces the cover window 20 by supporting the surface opposite to the attachment surface of the panel 10.

Accordingly, the gap between the window attachment member 200 to which the cover window 20 is attached and the panel support member 100 supporting the panel 10 is adjusted such that the attachment surface of the cover window 20 and the attachment surface of the panel 10 can be brought into contact with each other. At this time, the gap between the window attachment member 200 and the panel support member 100 may be adjusted using the gap adjustment member 500, and the gap between the window attachment member 200 and the panel support member 100 may be adjusted by moving at least any one of the window attachment member 200 and the panel support member 100.

Subsequently, the elastic pressing member presses a portion of the panel against the cover window for the first time (S300). The elastic pressing member 130 may be at least partially pressed while reducing a gap between the window attachment member 200 and the panel support member 100. Accordingly, the elastic pressing member 130 may press a portion of the panel 10 against the cover window 20 for the first time while being elastically deformed.

Further, the panel is pressed again by supplying a fluid to expand the diaphragm (S400). A fluid may be supplied to the membrane and at least a portion of the membrane may be expanded. Thus, the total area of the panel may be pressed against the cover window.

Subsequently, the window attachment member and the panel support member are separated from each other (S500). At this time, the gap between the window attachment member 200 and the panel support member 100 may be adjusted using the gap adjustment member 500, and the gap between the window attachment member 200 and the panel support member 100 may be adjusted by moving at least any one of the window attachment member 200 and the panel support member 100.

In an exemplary embodiment, a portion of the panel 10 is previously pressed using the elastic pressing member 130, and then, the diaphragm 120 is expanded while supplying the fluid F to completely press the panel 10. Therefore, even a curved surface can be uniformly pressed, and even lamination can be provided without shaking even during pressing of the entire surface.

Further, providing the panel to be adhered on the carrier sheet and fixing the panel to the panel supporting member (S200) may include: supporting a carrier sheet at an upper end of the panel support member; pulling the two ends of the carrier sheet; and a panel fixing member fixing the carrier sheet along an outer surface of the panel supporting member.

The carrier sheet 30 may be pressed using the panel fixing member 100 so that the panel 10 may be fixed along the outer surface of the panel supporting member 100. At this time, in the panel fixing member 100, for example, a roller may be used, which is fastened to the extension arm and may move as the arm swings around the rotation axis, but the embodiment is not particularly limited thereto.

For example, when the panel 10 is directly fixed to the panel support part 100 using a fixing member or the like, damage may be caused to the display surface of the panel 10, and interference may be generated by the fixing member fixing the panel 10 when it is desired to press the panel 10 against the cover window 20. Accordingly, the panel 10 may be temporarily adhered to the carrier sheet 30, and the carrier sheet 30 is fixed to the panel support member 100, and thus, the panel 10 may be fixed to the panel support member 100.

At this time, for example, a tacky UV adhesive sheet may be used for the carrier sheet 30, and when the carrier sheet 30 is irradiated with ultraviolet rays after the effect of attaching the panel 10 is completed, the adhesiveness of the carrier sheet 30 may be lost, and the carrier sheet may be removed from the panel 10. Such a carrier sheet 30 is sufficient to temporarily fix the panel 10, and the embodiment is not particularly limited thereto.

Here, a portion of the carrier sheet 30 to which the panel 10 is attached may be supported at the upper end of the panel supporting member 100, and for example, a pulling member such as a jig may be used so that both ends of the carrier sheet 30 may be held in a pulled state.

Therefore, a carrier sheet that loses adhesiveness through a curing step after separating the window attachment member and the panel support member from each other (S500) may be further provided.

The carrier sheet that is unattached by the curing step may further comprise: separating the window fixing part and the panel supporting part from each other by the gap adjusting part; irradiating UV light with UV light to an exposed surface of the carrier sheet adhered to the other surface facing the one surface with the one surface of the cover window and the panel attached to each other; and removing the UV sheet, which has lost the adhesiveness due to UV irradiation, from one surface of the panel.

Here, with UV irradiation, the cover window 20 is separated from the window attachment member 200, and UV may be emitted to the carrier sheet 30 above the cover window 20. Alternatively, the panel support member 100, the panel 10, and the carrier sheet 30 are separated, and UV may be emitted to the exposed surface of the carrier sheet 30.

Further, the elastic pressing member may be performed to press a portion of the panel against the cover window for the first time (S300), so that the elastically deformed elastic pressing member transmits elastic force to the panel.

The gap between the window attachment member 200 and the panel support member 100 may be reduced by the gap adjustment member 500, and when the gap is further reduced after the gap is reduced and the cover window 20 and the panel 10 are brought into contact with each other, the elastic pressing member 130 may be at least partially pressed. At this time, the elastic pressing member 130 may transmit elastic force to the panel 10 while being elastically deformed, a portion of the panel 10 may be locally pressed against the curved surface region of the cover window 20 by the transmission of the elastic force, and accurate lamination may be provided in the curved surface region.

Further, pressing the panel against the cover window again (S400) may be performed such that the lower portion of the diaphragm expands after the upper portion of the diaphragm expands.

Here, the diaphragm 120 may have, for example, a wall body shape such that the panel 10 is fixed along an outer surface of the diaphragm 120, and such that the diaphragm 120 may be expanded by the fluid F supplied into the wall body shape.

The upper side of the diaphragm 120 is previously expanded and presses a portion of the panel 10 against the cover window 20, and then, the entire surface of the panel 10 may be pressed against the cover window 20 while the lower side of the diaphragm is expanded. Therefore, accurate lamination can be provided in the curved surface region of the cover window 20, and air bubbles can be prevented from occurring between the cover window 20 and the panel 10.

At this time, a plurality of flow channels 112 may be provided, the body member 110 may further include a plurality of injection ports 113 communicating with the plurality of flow channels 112, and at least a portion of the plurality of injection ports 113 may be positioned at mutually different positions.

In addition, a fluid supply part (not shown) for supplying the fluid F to the plurality of injection ports 113 may be further provided, and the fluid supply part (not shown) may sequentially supply the fluid F to the plurality of injection ports 113 according to the height of the injection ports 113.

Inflating the diaphragm with the fluid and secondly pressing the panel to the cover window (S400) may include: a fluid supply member supplying fluid to the ejection port at a high position and expanding the diaphragm above the panel support member; and the fluid supporting member supplies the fluid to the ejection port located at a smaller height than the ejection port at the high position and expands the entire surface of the diaphragm.

Further, in expanding the diaphragm by the fluid and secondly pressing the panel to the cover window (S400), the thickness of the elastic film constituting the diaphragm 120 may be set to be greater in the lower side than in the upper side of the panel supporting member 100. Accordingly, since the diaphragm 120 is easily expanded at the upper side of the panel supporting member 100, the fluid supply may be performed such that the upper side is first expanded when the fluid F is supplied.

Accordingly, the panels 10 may be sequentially pressed from the upper curved region by the diaphragm 120, bubbles may be prevented from occurring between the cover window 20 and the panels 10 by pressing irregular positions, and the panels 10 may be precisely pressed against the cover window 20.

Thus, in the present disclosure, the elastic pressing member and a portion covering the window may be pressed first by reducing the gap between the window attachment member and the panel support member, and the entire region of the panel may be pressed second by expanding the diaphragm. Accordingly, accurate pressurization can be provided to a curved area that needs to be accurately pressed, the entire area can be pressed without shaking, and a cover window and a flexible panel having an at least partially bent portion can be firmly laminated without defects. Further, the shaft-like rigid body part is provided to the elastic pressing part, and the position of the elastic body part is fixed to the main body part, and therefore, during the first pressurization using the elastic pressing part, excessive deformation or inclination of the elastic body part can be prevented, and an accurate position can be pressed. Further, the flexible panel is pressed using a diaphragm usable for any type of cover window, so that cover windows having various curvatures can be provided with high-accuracy lamination without replacement with new additional equipment. At this time, the carrier sheet for fixing the panel and the panel fixing member for fixing the panel to the panel supporting member are used, so that the panel can be fixed to the panel supporting frame without causing damage to the screen member of the panel, and the panel can be pressed against the cover window without error. Further, in the window panel laminating method according to another exemplary embodiment, when the panel is pressed against the cover window, the panel is sequentially pressed from an upper side to a lower side of the panel supporting member, so that bubbles may be prevented from occurring between the cover window and the panel. A method in which the thickness of the membrane is set to be different according to the height thereof and the expansion speed is different at each height and/or a method in which the height of the ejection port for supplying the fluid to the membrane is set to be different and the fluid is sequentially supplied from the upper side may be used in such sequential lamination. Thus, the sequential pressurization can be provided entirely from the upper side of the diaphragm, and the flexible panel can be firmly laminated even to the cover window having the at least partially curved portion by the high-accuracy pressing method.

In the window panel laminating apparatus according to the exemplary embodiment, a portion of the cover window may be pressed with the elastic pressing member first by reducing the gap between the window attaching member and the panel supporting member, and the entire region of the panel may be pressed by expanding the diaphragm second. Accordingly, accurate pressurization can be provided to a curved area that needs to be accurately pressed, the entire area can be pressed without shaking, and a cover window and a flexible panel having an at least partially bent portion can be firmly laminated without defects.

Further, the shaft-like rigid body part is provided to the elastic pressing part, and the position of the elastic body part is fixed to the main body part, and therefore, during the first pressurization using the elastic pressing part, excessive deformation or inclination of the elastic body part can be prevented, and an accurate position can be pressed.

Further, the flexible panel is pressed using a diaphragm usable for any type of cover window, so that cover windows having various curvatures can be provided with high-accuracy lamination without replacement with new additional equipment.

At this time, the carrier sheet for fixing the panel and the panel fixing member for fixing the panel to the panel supporting member are used, so that the panel can be fixed to the panel supporting frame without causing damage to the screen member of the panel, and the panel can be pressed against the cover window without error.

Further, in the window panel laminating method according to another exemplary embodiment, when the panel is pressed against the cover window, the panel is sequentially pressed from an upper side to a lower side of the panel supporting member, so that bubbles may be prevented from occurring between the cover window and the panel. A method in which the thickness of the membrane is set to be different according to the height thereof and the expansion speed is different at each height and/or a method in which the height of the ejection port for supplying the fluid to the membrane is set to be different and the fluid is sequentially supplied from the upper side may be used in such sequential lamination. Thus, the sequential pressurization can be provided entirely from the upper side of the diaphragm, and the flexible panel can be firmly laminated even to the cover window having the at least partially curved portion by the high-accuracy pressing method.
