Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments.

[0025] In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0026] The utility model provides an AMOLED liquid crystal display screen that solves the problem of polarizer punching cracks, characterized in that it includes AMOLED screen glass, a polarizer, a cover plate and optical glue, the polarizer is arranged on the upper surface of the AMOLED screen glass, the polarizer includes a base part and an edge grinding part extending outward from the base part, and the edge grinding part can be removed by edge grinding before or after assembly; the cover plate is arranged above the polarizer; the polarizer and the cover plate are bonded by the optical glue.

[0027] Since the polarizer includes a base portion and an edge grinding portion extending outward from the base portion, the edge grinding portion can be removed by edge grinding before or after assembly, that is, when the polarizer is punched, the edge grinding portion is punched, and after the punching is completed, the edge grinding portion is removed by edge grinding, and only the base portion is retained, thereby removing the cracked portion, preventing the punching cracks of the polarizer from entering the module, avoiding affecting the display effect of the module, and improving the competitiveness of the product.

[0028] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.

[0029] See also Figure 1 and Figure 2, an AMOLED liquid crystal display screen for solving the punching cracks of polarizer provided by the utility model, comprising an AMOLED screen glass 1, a polarizer 2, a cover plate 3 and an optical adhesive 4, wherein the polarizer 2 is arranged on the upper surface of the AMOLED screen glass 1, the polarizer 2 comprises a base portion 21 and an edge grinding portion 22, the edge grinding portion 22 is formed by extending outward from the base portion 21, and the edge grinding portion 22 can be removed by edge grinding before or after assembly; the cover plate 3 is arranged above the polarizer 2; the polarizer 2 and the cover plate 3 are bonded by the optical adhesive 4. Since the polarizer 2 includes a base portion 21 and an edge grinding portion 22 extending outward from the base portion 21, the edge grinding portion 22 can be removed by edge grinding before or after assembly, that is, when the polarizer 2 is punched, the edge grinding portion 22 is punched, and after the punching is completed, the edge grinding portion 22 is removed by edge grinding, and only the base portion 21 is retained, thereby removing the cracked portion, preventing the punching cracks of the polarizer 2 from entering the interior of the module, avoiding affecting the display effect of the module, and improving the competitiveness of the product.

[0030] Furthermore, the depth of a general crack is within 0.5 mm, and therefore, the distance that the edge grinding portion 22 extends outward is greater than or equal to 0.5 mm. In the present embodiment, the distance that the edge grinding portion 22 extends outward is 0.5 mm. If some materials or processing techniques cause the crack to be greater than 0.5 mm, the distance that the edge grinding portion 22 extends outward may be increased according to actual needs.

[0031] Furthermore, the polarizer 2 includes a release film, a first PSA layer, a first LC layer, a second PSA layer, a second LC layer, a third PSA layer, a POL layer, and a PET protective film which are sequentially stacked from bottom to top. The thickness of the first PSA layer is 15 μm, the thickness of the first LC layer is 1 μm, the thickness of the second PSA layer is 6 μm, the thickness of the second LC layer is 2 μm, and the thickness of the third PSA layer is 12 μm. The release film and the PET protective film can be torn off during assembly.

[0032] Furthermore, the width of the polarizer 2 is 34.07 mm.

[0033] See also Figure 3As a further optimization scheme of Example 1, in this embodiment, the cover plate 3 includes a visible area and a non-visible area, and the lower surface of the cover plate 3 located in the non-visible area is provided with an ink layer 5, and the lower surface of the cover plate 3 located in the visible area is coated with an optical glue 4, and the optical glue 4 extends and covers the lower surface of the ink layer 5 close to the visible area. The ink layer 5 away from the visible area is not covered by the optical glue 4 and forms an empty layer area, and the lower surface of the optical glue 4 forms a smooth surface. Since the optical glue 4 is directly coated on the lower surface of the cover plate 3 and extends to the lower surface of the ink layer 5, instead of being directly attached to the lower surface of the cover plate 3 by using an optical glue 4 tape as in the traditional technology, the lower surface of the optical glue 4 can be formed into a smooth surface, and there is no height difference on the lower surface of the optical glue 4, so that the cover plate 3 will not generate bubbles and edge yellow spots when being attached, avoiding display abnormalities, thereby reducing the probability of defective products, and the production and manufacturing costs will also be greatly reduced, thereby improving the competitiveness of the product, thereby meeting the growing quality requirements of enterprises.

[0034] Furthermore, the width of the optical adhesive 4 extending and covering the ink layer 5 is 0.6 mm to 0.8 mm.

[0035] Furthermore, the thickness of the ink layer 5 is 8 μm to 15 μm.
