Technical Field

The invention relates to the technical field of display, in particular to a polarizer assembly, a film tearing method thereof and a preparation method of a display module.

Background

In the related art, after the display panel is manufactured, the edge (e.g., the periphery or a part of the side edge in the periphery) of the display panel is usually cut, for example, when the display panel has an irregular shape, e.g., a rectangle with rounded corners or an indent (i.e., Notch), the display panel needs to be cut in a special shape, and after the cutting is completed, the waste material needs to be removed.

The waste material is removed by absorbing the cut waste material (i.e. Dummy) by the suction nozzle, and the suction nozzle has a certain size, and the width of the waste material is at least equal to the size of the suction nozzle, so that correspondingly, the width of the cut part on the display panel should be at least equal to the size of the suction nozzle, thereby reducing the utilization rate of the supporting substrate in the process of preparing the display panel, namely, causing the typesetting rate of the display panel to be lower, and further increasing the production cost.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

In the related art, as shown in fig. 1, when preparing the display panel 11, a plurality of display panels 11 are prepared on a supporting substrate 12, and then the plurality of display panels 11 are divided to obtain the display unit 14 shown in fig. 2, wherein the display unit 14 includes the display panel and the scrap portion 13. After cutting the display unit 14, the scrap part 13 needs to be removed. Because the suction nozzle has a certain size, the width W of the waste material part 13 is at least equal to the size of the suction nozzle, and accordingly, the width W of the waste material part 13 should also be at least equal to the size of the suction nozzle, so that the utilization rate of the supporting substrate in the process of preparing the display panel is reduced, that is, the typesetting rate of the display panel is low, and the production cost is increased.

In order to solve the above technical problems, embodiments of the present invention provide a polarizer assembly, a film tearing method thereof, and a manufacturing method of a display module, which can reduce the size of a first cut portion of a display substrate, improve the utilization rate of a support substrate in the process of manufacturing a display panel, improve the layout rate of the display panel, and reduce the production cost. Moreover, the film tearing quality and success rate can be improved.

The embodiment of the invention provides a polarizer assembly. As shown in fig. 3, the polarizer assembly is formed with a first region Q1 and a second region Q2, as shown in fig. 3, the polarizer assembly includes: a polarizer 21 and a first protective film 22.

In the present embodiment, as shown in fig. 3, the first protective film 22 is adhered to the surface of the polarizer 21. The first protection film 22 includes a first protection portion 221 and a second protection portion 222. The first protection portion 221 is located in the first region Q1, and the second protection portion 222 is located in the second region Q2. The second protection portion 222 partially surrounds the first protection portion 221, and the second protection portion 222 and the first protection portion 221 are separated from each other. As shown in fig. 4, the first protective portion 221 extends in the longitudinal direction Y of the polarizer 21, and the second protective portion 222 extends in the longitudinal direction Y. In the longitudinal direction Y, a space is present between a first end T1 of the first protection portion 221 near the first short side of the polarizer 21 and a first end T2 of the second protection portion 222 near the first short side.

In the present embodiment, since the first protective film 22 adhered to the surface of the polarizer 21 includes the first protective portion 221 and the second protective portion 222, the first protective portion 221 is located in the first region Q1 of the polarizer assembly, the second protective portion 222 is located in the second region Q2 of the polarizer assembly, and the second protective portion 222 and the first protective portion 221 are separated from each other, so that the second protective portion 222 can be torn from the polarizer 21 while the first protective portion 221 remains on the polarizer 21. Therefore, when the polarizer assembly after the film tearing is attached to the display substrate and the waste material is removed after the display substrate and the polarizer assembly after the film tearing are cut, the first protection part 221 is adhered to the removing part of the polarizer 21, and the removing part of the polarizer 21 is adhered to the first cutting part of the display substrate, so that the first cutting part and the second cutting part can be removed by the waste discharge device through adsorbing the first protection part 221, the waste material removal is realized, the size of the first cutting part of the display substrate can be reduced, the utilization rate of the support substrate in the process of preparing the display panel is improved, the typesetting rate of the display panel is improved, and the production cost is reduced.

Moreover, since the second protection portion 222 and the first protection portion 221 are separated from each other, when the second protection portion 222 is torn from the polarizer 21, the first protection portion 221 is prevented from being dislocated due to the fact that the first protection portion 221 is pulled, and the quality of the torn film is improved.

Furthermore, since the first protection portion 221 extends along the long side direction Y of the polarizer 21 and the second protection portion 222 extends along the long side direction Y, and there is a gap between the first end of the first protection portion 221 near the first short side of the polarizer 21 and the first end of the second protection portion 222 near the first short side in the long side direction Y, when the second protection portion 222 is peeled off from the polarizer 21 by using the film peeling tool, since one end of the film peeling tool is attached to the attaching position of the second protection portion 222 and the attaching position is located at the first end of the second protection portion 222, there is a gap between the attaching position and the first end of the first protection portion 221, and therefore, it is possible to prevent the first protection portion 221 from being peeled off when the second protection portion 222 is peeled off from the polarizer 21, thereby improving the quality and success rate of film peeling, and reducing the difficulty of attaching one end of the film peeling tool to the attaching position of the second protection portion 222, is favorable for improving the film tearing efficiency.

The polarizer assembly according to the embodiment of the present invention is briefly described above, and the polarizer assembly according to the embodiment of the present invention is described in detail below.

The embodiment of the invention also provides a polarizer assembly. The polarizer assembly, as shown in fig. 3 to 4, is formed with two first regions Q1 and a second region Q2. The two first regions Q1 are adjacent to the second region Q2, respectively. For each first region Q1, the second region Q2 surrounds the first region Q1 from three sides, and the first region Q1 is rectangular. The second region Q2 is i-shaped. The shape of the first region Q1 is complementary to the shape of the second region Q2. Two first regions Q1 are located on both sides of the second region Q2 in the short side direction X of the polarizer 21.

In this embodiment, as shown in fig. 3, the polarizer assembly includes: a polarizer 21, a first protection film 22, an adhesive layer 23, and a second protection film 24.

As shown in fig. 3, the adhesive layer 23 is located between the polarizer 21 and the first protective film 22. The first protective film 22 is adhered to the polarizer 21 through an adhesive layer 23. The adhesive layer 23 may be a pressure sensitive adhesive, but is not limited thereto.

In the present embodiment, the first protection film 22 may be a release film. As shown in fig. 3 to 4, the first protection film 22 includes two first protection portions 221 and one second protection portion 222. The first protection portions 221 are located in the corresponding first regions Q1, and the second protection portions 222 are located in the second regions Q2. For each first protection portion 221, the second protection portion 222 surrounds the first protection portion 221 from three sides, and the shape of the second protection portion 222 is complementary to that of the first protection portion 221. The second protection portion 222 and the first protection portion 221 are separated from each other.

As shown in fig. 4, the first protective portion 221 extends in the longitudinal direction Y of the polarizer 21, and the second protective portion 222 extends in the longitudinal direction Y. In the longitudinal direction Y, a space is present between a first end T1 of the first protection portion 221 near the first short side of the polarizer 21 and a first end T2 of the second protection portion 222 near the first short side.

In the present embodiment, in the long-side direction Y, there is a gap between the second end T3 of the first protection portion 221 near the second short side of the polarizer 21 and the second end T4 of the second protection portion 222 near the second short side, and the second short side of the polarizer 21 is opposite to the first short side of the polarizer 21.

As shown in fig. 4, two first protection portions 221 are located on both sides of the second protection portion 222 in the short direction X of the polarizer 21. Also, the two first protection portions 221 are symmetrical with respect to the symmetry axis P of the second protection portion 222. The symmetry axis P extends in the longitudinal direction Y.

In the present embodiment, as shown in fig. 3, the second protective film 24 is located on the side of the polarizer 21 opposite to the first protective film 22.

Before the polarizer assembly is attached to the display panel, the second protective portion 222 needs to be peeled off from the polarizer 21, and the first protective portion 221 needs to be left on the polarizer 21. Then, the second region Q2 is aligned with the display substrate, and the polarizer assembly is attached to the display substrate.

In the present embodiment, since the first protective film 22 adhered to the surface of the polarizer 21 includes the first protective portion 221 and the second protective portion 222, the first protective portion 221 is located in the first region Q1 of the polarizer assembly, the second protective portion 222 is located in the second region Q2 of the polarizer assembly, and the second protective portion 222 and the first protective portion 221 are separated from each other, so that the second protective portion 222 can be torn from the polarizer 21 while the first protective portion 221 remains on the polarizer 21. Moreover, since the second protection portion 222 and the first protection portion 221 are separated from each other, when the second protection portion 222 is torn from the polarizer 21, the first protection portion 221 is prevented from being dislocated due to the fact that the first protection portion 221 is pulled, and the quality of the torn film is improved.

In this embodiment, when the polarizer assembly after the film tearing is attached to the display substrate and the waste material is removed after the display substrate and the polarizer assembly after the film tearing are cut, the first protection portion 221 is adhered to the removing portion of the polarizer 21, and the removing portion of the polarizer 21 is adhered to the first cutting portion of the display substrate, so that the first cutting portion and the second cutting portion can be removed by the waste discharge device through adsorbing the first protection portion 221, the waste material removal is realized, the size of the first cutting portion of the display substrate can be reduced, the utilization rate of the support substrate in the process of preparing the display panel is improved, the typesetting rate of the display panel is improved, and the production cost is reduced. For example, the width of the first cutout may be reduced from 2 mm to 0.05 mm, or may be reduced to a smaller size.

Furthermore, since the first protection portion 221 extends along the long side direction Y of the polarizer 21 and the second protection portion 222 extends along the long side direction Y, and there is a gap between the first end of the first protection portion 221 near the first short side of the polarizer 21 and the first end of the second protection portion 222 near the first short side in the long side direction Y, when the second protection portion 222 is peeled off from the polarizer 21 by using the film peeling tool, since one end of the film peeling tool is attached to the attaching position of the second protection portion 222 and the attaching position is located at the first end of the second protection portion 222, there is a gap between the attaching position and the first end of the first protection portion 221, and therefore, it is possible to prevent the first protection portion 221 from being peeled off when the second protection portion 222 is peeled off from the polarizer 21, thereby improving the quality and success rate of film peeling, and reducing the difficulty of attaching one end of the film peeling tool to the attaching position of the second protection portion 222, is favorable for improving the film tearing efficiency.

The embodiment of the invention also provides a film tearing method of the polarizer assembly. As shown in fig. 5, the method for tearing a polarizer assembly may include the following steps 501 to 502:

in step 501, one end of the film tearing tool is pasted on a pasting position of the second protection part, and the pasting position is located at the first end of the second protection part; the other end of the film tearing tool is a tearing position.

In this embodiment, the film tearing tool may be a peel-off sticker, but is not limited thereto. As shown in fig. 6, one end of the easy-tear sticker 61 may be stuck to the sticking position of the second protection portion 222. The sticking position is located at the first end T2 of the second protection portion 222, and the other end of the easy-to-tear sticker 61 is a tearing position.

In the embodiment, the pasting position is located on the side of the symmetry axis P close to the first vertex Dot1 of the second protection portion 222, and the first vertex Dot1 is the vertex of the second protection portion 222 close to the first short side. Compared with the middle of the adhering position at the first end T2 of the second protection portion 222, the adhering position at the side of the symmetry axis P close to the first vertex Dot1 of the second protection portion 222 can reduce the magnitude of the initial force during film tearing, and avoid the failure of the polarizer assembly caused by the film peeling (peeling) of the polarizer 21, the adhesive layer 23, and the second protection film 24.

Of course, in other embodiments, the paste bit may be located at the first vertex Dot 1. In this way, the magnitude of the initial force at the time of tearing the film can be further reduced.

In other embodiments, the pasting position may also be located on the side of the symmetry axis P close to the second vertex Dot2 of the second protection portion 222, and the second vertex Dot2 is a vertex of the second protection portion 222 close to the second short side.

In this embodiment, since there is a gap between the first end of the first protection portion 221 close to the first short side of the polarizer 21 and the first end of the second protection portion 222 close to the first short side in the longitudinal direction Y, when the second protection portion 222 is peeled off from the polarizer 21 by using the film peeling tool, since one end of the film peeling tool is attached to the attaching position of the second protection portion 222, which is located at the first end of the second protection portion 222, there is a gap between the attaching position and the first end of the first protection portion 221, so that the first protection portion 221 is prevented from being peeled off when the second protection portion 222 is peeled off from the polarizer 21, thereby improving the film peeling quality and the success rate. Moreover, since there is also a gap between the pasting position and the first end of the first protection portion 221, the probability of pasting one end of the film tearing tool at the junction of the second protection portion 222 and the first protection portion 221 is reduced, the spatial limitation on the operation of pasting one end of the film tearing tool at the pasting position of the second protection portion 222 is reduced, the difficulty of pasting one end of the film tearing tool at the pasting position of the second protection portion 222 is reduced, and the film tearing efficiency is improved.

In step 502, a pulling force is applied to the tearing hand to tear the second protection portion 222 from the polarizer 21, so as to obtain a polarizer assembly after the film is torn.

In this embodiment, as shown in fig. 7 to 8, the second protection portion 222 is torn off from the polarizer 21 to obtain a peeled polarizer assembly, which includes the polarizer 21, the first protection portion 221, the adhesive layer 23 and the second protection film 24. Wherein fig. 8 is a cross-sectional view along section line AA of fig. 7.

In this embodiment, as shown in fig. 10, the display substrate 31 includes a display panel 311 and a first cut-out portion 312. As shown in fig. 11, the polarizer 21 includes a reserved portion 211 of the polarizer 21 and a removed portion 212 of the polarizer 21. As shown in fig. 12, the adhesive layer 23 includes a remaining portion 231 of the adhesive layer 23 and a removed portion 232 of the adhesive layer 23. The polarizer assembly after the film peeling includes the second cut portion, the reserved portion 211 of the polarizer 21, the reserved portion of the second protective film 24, and the reserved portion 231 of the adhesive layer 23. As shown in fig. 13, the second cut portion includes the first protection portion 221, the removal portion 212 of the polarizer 21, the removal portion of the second protection film 24, and the removal portion 232 of the adhesive layer 23. The first protection portion 221 is adhered to the removed portion 212 of the polarizer 21, the removed portion of the second protection film 24, and the removed portion of the adhesive layer 23.

In this embodiment, as shown in fig. 14, the roller 33 may be used to attach the peeled polarizer assembly to the display substrate 31, and as shown in fig. 15, a partial projection of the display substrate 31 on the peeled polarizer assembly is located in the second region Q2.

In this embodiment, in the process of attaching the polarizer assembly after being peeled to the display substrate 31 by using the roller 33, the display substrate 31 is located on the carrier, and since the first protection portion 221 is located on the side of the polarizer 21 facing the carrier, the adhesion of the adhesive layer 23 to the carrier can be avoided, so that the carrier does not need to be designed to be anti-adhesive, and the equipment and fixture cost is saved.

In step 903, cutting the display substrate and the polarizer assembly after the film is torn to cut off the first cut-off portion and the second cut-off portion, so as to obtain a display module; the first protection part is adhered to the removing part of the polarizer, the removing part of the polarizer is adhered to the first cutting part of the display substrate, and the display module comprises a display panel and a reserved part of the polarizer.

In this embodiment, as shown in fig. 15, the display substrate 31 and the polarizer assembly after the film is peeled may be subjected to special-shaped cutting along a direction perpendicular to the display substrate 31 by using a laser cutting process to cut the first cut portion and the second cut portion.

In step 904, the first cut portion and the second cut portion are removed with a waste device that removes the first cut portion and the second cut portion by adsorbing the first protection portion.

In this embodiment, as shown in fig. 15, the suction position 35 of the first protection portion 221 is sucked by the suction nozzle of the waste discharging apparatus, and the first cut portion and the second cut portion are removed by sucking the first protection portion 221, so as to obtain the display module 36 shown in fig. 16, where the first cut portion and the second cut portion can be as shown in fig. 17. The display module 36 includes a display panel 311, a retention portion 211 of the polarizer 21, a retention portion 231 of the adhesive layer 23, and a retention portion of the second protective film 24.

In this embodiment, when the polarizer assembly after the film tearing is attached to the display substrate and the waste material is removed after the display substrate and the polarizer assembly after the film tearing are cut, the first protection portion 221 is adhered to the removing portion of the polarizer 21, and the removing portion of the polarizer 21 is adhered to the first cutting portion of the display substrate, so that the first cutting portion and the second cutting portion can be removed by the waste discharge device through adsorbing the first protection portion 221, the waste material removal is realized, the size of the first cutting portion of the display substrate can be reduced, the utilization rate of the support substrate in the process of preparing the display panel is improved, the typesetting rate of the display panel is improved, and the production cost is reduced.

In this embodiment, as shown in fig. 18, after step 904, the method further includes: a third protection film 37 is attached to the display module 36, the third protection film 37 is located on a side of the display panel 311 opposite to the reserved portion of the polarizer 21, and an edge of the display module 36 is retracted relative to an edge of the third protection film 37. In this way, the risk of cracking the display module 36 can be avoided.
