Technical Field

[0001] The utility model relates to the technical field of polarizers, in particular to a polarizer for a liquid crystal display screen. Background Art

[0002] A polarizer is an optical material that can selectively transmit light in a certain direction and block light in other directions. This property makes the polarizer play an important role in many optical applications, including liquid crystal displays, 3D glasses, sunglasses, etc.

[0003] In the Chinese utility model patent with the publication number CN216310305U, a polarizer for a computer liquid crystal display screen is disclosed. Through the cooperation among the anti-peeping layer, the blue light filtering layer and the anti-reflection film layer, the overall polarizer can better protect the user's eyes, solving the problems that it is easy to cause harm to the eyes during long-term use and the content displayed during use is easy to be peeked at by surrounding people, thus making the polarizer inconvenient to use, further affecting the use efficiency of the polarizer and reducing the use effect. For the above related technologies, the inventor believes there are the following defects:

[0004] When the polarizer is actually used, since the cross-section of the polarizer is directly exposed to the outside, moisture in the outside air is likely to erode the cross-section of the polarizer, resulting in bubbles and white edges at the edge of the polarizer, and further causing poor display of the liquid crystal display screen. Therefore, we provide a polarizer for a liquid crystal display screen. Summary of the Utility Model

[0005] To solve the problem in the above background art that moisture in the outside air is likely to erode the cross-section of the polarizer, resulting in bubbles and white edges at the edge of the polarizer, and further causing poor display of the liquid crystal display screen, the utility model provides a polarizer for a liquid crystal display screen.

[0006] The utility model is realized by the following technical solutions: A polarizer for a liquid crystal display screen, comprising:

[0007] A polarizer main body, a chamfered slope is arranged at the edge of the polarizer main body, and a protective film layer is bonded to the surface of the polarizer main body.

[0008] As a further improvement of the above solution, the polarizer main body successively includes a TAC film layer, a PVA film layer, a pressure-sensitive film layer and a release film layer from top to bottom.

[0009] As a further improvement of the above solution, the TAC film layer is two layers and is respectively bonded to the top and bottom of the PVA film layer.

[0010] As a further improvement of the above solution, an anti-fouling layer is coated on the outer surface of the protective film layer.

[0011] As a further improvement of the above solution, the thickness of the protective film layer is 58 μm.

[0012] As a further improvement of the above solution, the thickness of the TAC film layer is 80 μm.

[0013] As a further improvement of the above solution, the thickness of the PVA film layer is 30 μm.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By providing a chamfered slope at the edge of the polarizer main body, the present utility model can not only prevent the increase in the thickness due to bending at the edge of the polarizer main body, making the stress at the four corners and the four edges of the polarizer main body uniform, but also effectively avoid problems such as edge light leakage and edge burning, with strong practicability.

[0016] 2. By covering the cross-section of the polarizer main body with the protective film layer, the present utility model can effectively prevent the erosion of the cross-section of the polarizer main body by moisture in the external air, thereby avoiding problems such as bubbles and white edges at the edge of the polarizer main body, which may cause poor display of the liquid crystal display screen, and further improving the practicability of the device.
