In addition, examples of various specific processes and materials are provided herein, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.

A polarizer is a very important component of a display panel, mainly used to convert incident light into natural light. However, in the process of laminating the polarizer to the curved plate, the curved plate is easy to deform the laminated polarizer due to the large strain force generated by the laminated polarizer, so that the phenomenon of fold after lamination of the polarizer is caused, and the product is poor.

Referring to fig. 1 and 2, in view of the above, the present application provides a polarizer 10, where the polarizer 10 of the embodiment of the present application includes a substrate 11, a first adhesive layer 12, an optical functional layer 13, a second adhesive layer 14, a liquid crystal layer 15, and a third adhesive layer 16, which are sequentially stacked, the first adhesive layer 12 adheres the substrate 11 and the optical functional layer 13, the second adhesive layer 14 adheres the optical functional layer 13 and the liquid crystal layer 15, the substrate 11 is formed with a patterned structure, the patterned structure includes a material region 1121 and regularly arranged hollow-out regions 1122, and the optical functional layer 13 is configured to convert incident light into polarized light.

In the polarizer 10 of the present application, through forming the patterned structure including the regularly arranged hollow areas 1122 and the material areas 1121 in the substrate 11, the stress generated in the lamination process of the polarizer 10 can be effectively absorbed by the hollow areas 1122, so that the phenomenon of wrinkles caused by the deformation of the stress when the polarizer 10 is laminated on a curved plate is avoided, and thus, the product yield is improved.

It should be noted that the polarizer 10 of the present application may be applied to a display panel having a curved surface or a flat surface. For example, in the present embodiment, the polarizer 10 is used for a curved display panel. Therefore, wrinkles caused by stress generated by the polarizer 10 when the curved display panel is attached can be avoided.

Specifically, the area size and shape of the polarizer 10 may correspond to the area and shape of the display panel attached to the polarizer, and the larger the area of the display panel is, the larger the area of the polarizer 10 is. The area of the polarizer 10 may be greater than, equal to, or slightly smaller than the area of the display panel, for example, in the present embodiment, the area of the polarizer 10 may be equal to the area of the display panel. The shape of the polarizer 10 is the same as that of the display panel, for example, if the display panel is rectangular, the polarizer 10 is also rectangular.

The first Adhesive layer 12 is attached to the substrate 11, the first Adhesive layer 12 is used for adhering the substrate 11 to the Optical function layer 13, and the first Adhesive layer 12 may be a Pressure sensitive Adhesive (Pressure sensitive Adhesive), an optically Clear Adhesive (OCR), or an ethylene-vinyl acetate copolymer (EVA). This is not a limitation of the present application. For example, in some examples, the first adhesive layer 12 may be a pressure sensitive adhesive, such that the optically functional layer 13 may be quickly adhered to the substrate 11 via the first adhesive layer 12.

The thickness of the first adhesive layer 12 may be between 50um and 200um, such as 100um or 150 um. When the thickness of the first adhesive layer 12 is between 50um and 200um, the first adhesive layer 12 can be ensured to firmly adhere the substrate 11 and the optical function layer 13 together, and the transmittance of the first adhesive layer 12 can be ensured.

The second adhesive layer 14 is attached to the optically functional layer 13 for bonding the optically functional layer 13 and the liquid crystal layer 15, and the third adhesive layer 16 is attached to the liquid crystal layer 15 for bonding the liquid crystal layer 15 to the display panel so that the entire polarizer 10 is bonded to the display panel. The second adhesive layer 14 and the third adhesive layer 16 may be made of the same material as the first adhesive layer 12 or different materials. For example, the first adhesive layer 12 is made of a pressure sensitive adhesive, and the second adhesive layer 14 and the third adhesive layer 16 are made of an optically clear adhesive.

The optically functional layer 13 has a strong deformability, and may be made of Polyvinyl Alcohol (PVA) for converting incident light into polarized light.

In some embodiments, the optically functional layer 13 has a thickness of 4 to 20 μm. For example, the thickness of the optically functional layer 13 may be 4um, 5um, 6um, 7um, 8um, 10um, 12um, 14um, 15um, 17um, or 20um, etc. The specific thickness of the optical function layer 13 can be selected according to the model or material of the product, i.e., the application does not limit the thickness of the optical function layer 13.

The substrate 11 may be made of a hardened cellulose triacetate substrate film. The substrate 11 can protect the optical function layer 13, and the thickness of the substrate 11 is larger than that of the first adhesion layer 12.

The substrate 11 is formed with a patterned structure, which includes a material region 1121 and a hollow-out region 1122, i.e., a patterned structure is formed by the hollow-out region 1122 and the material region 1121.

The plurality of hollow-out areas 1122 include a plurality of hollow-out areas 1122, and the arrangement of the plurality of hollow-out areas 1122 in an array means that the centers of the plurality of hollow-out areas 1122 are staggered along at least two directions to form an array. In particular, the plurality of hollow-out areas 1122 may be staggered along two mutually perpendicular directions and arranged in an array, at this time, the two mutually perpendicular directions may be the row extending direction and the column extending direction of the hollow-out areas 1122 respectively, the hollow-out areas 1122 arranged along the row extending direction form hollow-out rows, and the hollow-out areas 1122 arranged along the column extending direction form hollow-out columns. The rows and the columns of the hollow areas 1122 in the polarizer 10 are opposite, and in this embodiment, the hollow areas 1122 arranged in rows may be the hollow areas 1122 arranged in columns in other embodiments, which are not expanded in detail herein.

Further, referring to fig. 2, fig. 4 and fig. 5, in some embodiments, in the hollow-out areas 1122 arranged in rows, each hollow-out area 1122 and the hollow-out areas 1122 in adjacent rows are arranged in a straight line along a column direction.

Referring to fig. 3 and 6, in some embodiments, in the hollow-out areas 1122 arranged in rows, each hollow-out area 1122 is staggered from the hollow-out areas 1122 in adjacent rows. Note that the misalignment means that the centers of two adjacent rows of the hollow-out areas 1122 are not on the same straight line in the column direction.

In some embodiments, the hollow-out areas 1122 may be in the shape of one or more of a circle, an ellipse, a triangle, or a parallelogram. Currently, in other embodiments, the shape of the hollow-out area 1122 may be other, such as a pentagon, a semicircle or an irregular figure. That is, the specific shape of the hollow-out region 1122 is not limited in this application.

For example, in some embodiments, the shape of the hollow-out areas 1122 is only one, and all of the hollow-out areas 1122 are circular (e.g., fig. 4), or all of the hollow-out areas 1122 are triangular, or all of the hollow-out areas 1122 are parallelogram-shaped (e.g., fig. 2 and 3).

For another example, in some embodiments, the shapes of the hollow-out areas 1122 are two, and the shape of the hollow-out areas 1122 includes a circle and a parallelogram (as shown in fig. 5-8), or the shape of the hollow-out areas 1122 includes a circle and a triangle, or the shape of the hollow-out areas 1122 includes a parallelogram and a triangle.

Further, referring to fig. 5 and fig. 6, in some embodiments, when the hollow areas 1122 have two shapes, each row has different adjacent hollow areas 1122, for example, the hollow areas 1122 have circular shapes and parallelogram shapes, and the hollow areas 1122 having circular shapes and elliptical shapes are alternately arranged in the same row.

Referring to fig. 7 and 8, in some embodiments, when the hollow areas 1122 have two shapes, the shapes of the hollow areas 1122 in adjacent rows are different. For example, the shapes of the hollow-out areas 1122 are circular and elliptical, and in adjacent rows, the hollow-out areas 1122 in one row are circular and the hollow-out areas 1122 in the other row are elliptical.

For another example, in some embodiments, the hollow-out regions 1122 are three in shape. The shape of the hollow-out area 1122 is circular, oval, or triangular, or the shape of the hollow-out area 1122 is circular, triangular, or parallelogram, or triangular, or oval.

Further, in some embodiments, when the shapes of the hollow areas 1122 are three, the shapes of the adjacent hollow areas 1122 in each row are different, for example, the hollow areas 1122 having the shapes of circular, oval and triangular are located in the same row, and the hollow areas 1122 having the shapes of circular, oval and triangular are alternately arranged.

In some embodiments, when the shapes of the hollow-out areas 1122 are three, the shapes of the hollow-out areas 1122 in three adjacent rows are different. For example, the shapes of the hollow areas 1122 are circular, oval and triangular, and in three adjacent rows, the hollow areas 1122 in one row are circular, the hollow areas 1122 in one row are oval, and the hollow areas 1122 in the other row are triangular.

Please further refer to fig. 2 and fig. 3, in the present embodiment, the hollow-out area 1122 is a parallelogram. The side length of the parallelogram is 50 um-2 mm, and the adjacent sides of the parallelogram can be equal or unequal, for example, the side lengths of the parallelogram are equal and 100um, and for example, the side lengths of the parallelogram are unequal, and one side of the two adjacent sides is 100um, and the other side is 150 um.

Furthermore, the angles of the four inner angles of the parallelogram are not limited, and can be any combination of 0-180 degrees, for example, in some embodiments, the acute angle of the parallelogram is 60 degrees, and the obtuse angle is 120 degrees

Of course, it should be noted that the number and the arrangement of the shapes of the hollow areas 1122 are only examples, and the hollow areas 1122 are not limited, for example, the shapes of the hollow areas 1122 may include four, five or more.

Referring to fig. 1 and 2, in some embodiments, the polarizer 10 includes a normal transmission region 111 and a deformation region 112, and the patterned structure is located in the deformation region 112.

The deformation region 112 refers to a region where stress is easily generated to deform the polarizer 10, and the normal transmission region 111 refers to a region where deformation is not easily generated. That is, the polarizer 10 may be divided into the normal transmission region 111 and the deformation region 112 so as not to be easily deformed to cause wrinkles. It can be understood that, since the polarizer 10 of the present application is attached to the display panel, if the display panel has a regular or irregular curved surface, the deformation of the polarizer 10 is likely to occur during the attachment process of the polarizer 10, and the deformation region 112 is a region where the polarizer 10 is likely to deform. The region where deformation does not easily occur is the normal light-transmitting region 111.

Thus, by locating the patterned structure in the deformation region 112, on one hand, the hollow-out region 1122 in the patterned structure can absorb the stress generated by the deformation region 112, thereby preventing the deformation region 112 from being deformed to generate wrinkles. The normal light-transmitting area 111 is not easy to deform, and on the other hand, only the deformation area 112 is provided with the patterned structure, which simplifies the processing process compared with the structure in which the patterned structure is arranged in the whole polarizer 10 area, thereby reducing the cost.

In some embodiments, the deformation region 112 is located at the edge of the polarizer 10. As the polarizer 10 is attached to the display panel, and the display panel is used for displaying, the display effect of the display panel is easily affected by the patterned structure of the deformation region 112, so that the deformation region 112 is located at the edge of the polarizer 10, and the deformation region 112 can be prevented from interfering with the display to the greatest extent. In addition, when the polarizer 10 is attached to the display panel, the edge of the polarizer 10 is most likely to be affected by the stress and generate wrinkles, that is, the edge of the polarizer 10 is most likely to cause wrinkles, so the deformation region 112 is disposed at the edge of the polarizer 10.

In some embodiments, the polarizer 10 has a quadrilateral shape (e.g., a rectangular shape), and the deformation region 112 is located at a corner of the quadrilateral shape.

It should be noted that. In this embodiment, the polarizer 10 is used for a display panel with four curved surfaces. In this way, the disturbance of the deformation region 112 to the display can be further reduced, and the corner of the quadrangle which is most easy to generate stress can be ensured to avoid generating wrinkles.

The present embodiment also provides a display device, which includes a display panel and the polarizer 10 of any one of the above embodiments, wherein the polarizer 10 covers the display panel.

In the display device of the application, through forming the patterned structure including the regularly arranged hollow areas 1122 and the material areas 1121 in the substrate 11, the stress generated in the lamination process of the polarizer 10 can be effectively absorbed by the hollow areas 1122, so that the phenomenon of wrinkles caused by the deformation of the stress when the polarizer 10 is laminated on the display panel is avoided, and thus, the product yield is improved.

The display device may be any of various types of computer system apparatuses that are mobile or portable and perform wireless communication, for example. Specifically, the display device may be a mobile phone or a smart phone (e.g., an iPhone-based phone), a Portable game device (e.g., Nintendo DS, PlayStation Portable, game Advance, iPhone), a tablet computer, a Portable internet device, a data storage device, etc., and the display device 100 may also be other wearable devices (e.g., a smart band, a smart watch, AR glasses, VR glasses, etc.).

In some cases, the display device may perform a variety of functions (e.g., playing music, displaying video, storing pictures, and receiving and sending telephone calls). The display device may be a portable device such as a cellular telephone, media player, other handheld device, wrist watch device, earpiece device or other compact portable device, if desired.

The display panel may be a liquid crystal display panel.

01, providing a substrate;

02, processing a base material to form a patterned structure, wherein the patterned structure comprises a material area and hollow-out areas which are regularly arranged;

03, arranging an adhesive layer on one side of the substrate with the patterned structure;

and 04, arranging an optical functional layer on the side of the adhesive layer far away from the substrate, wherein the optical functional layer is used for converting incident light into polarized light.

Thus, in the manufacturing method of the embodiment, before the polarizer 10 is formed, the substrate is formed into the patterned structure including the regularly arranged hollow areas and the material areas, the hollow areas can effectively absorb the stress generated by the polarizer 10 in the laminating process, so that the phenomenon of wrinkles caused by the deformation of the stress when the polarizer 10 is laminated on the curved plate is avoided, thus the product yield is improved, the substrate is provided with the patterned structure before the polarizer 10 is not formed, the interference on layers except the substrate is avoided, and the substrate is simply processed.

and 40, processing the substrate of the film layer structure to form a patterned structure, wherein the patterned structure comprises a material area and hollow-out areas which are regularly arranged.

In the manufacturing method of the embodiment, after the polarizer 10 is formed, the substrate 11 is formed into the patterned structure including the regularly arranged hollow areas and the material areas, and the hollow areas can effectively absorb the stress generated in the laminating process of the polarizer 10, so that the phenomenon of wrinkles caused by the deformation of the polarizer 10 due to the stress when the polarizer is laminated on a curved plate is avoided, thus the product yield is improved, and the existing polarizer 10 manufacturing process is not required to be improved.

In this embodiment, after the polarizer 10 is manufactured, the substrate of the polarizer 10 may be processed by laser half-cutting or chemical etching to form a hollow area, so as to implement the patterned structure.
