[0106] Based on the same inventive concept, the embodiments of the present application propose a method for preparing a polarizer, which is used to prepare the polarizer described in each of the above embodiments, such as Figure 9 shown, including:
[0107] Step 101 , using a cutting tool to cut and form a polarizer body with an arc structure.
[0108] Step 102, opening conducting grooves on the arc-shaped side surfaces of the arc-shaped structure.
[0109] In some embodiments, along the light emitting direction of the polarizer, the arc-shaped side is divided into a first part and a second part;
[0110] Such as Figure 10 As shown, the original step 101 remains unchanged, and the step 102 includes:
[0111] Step 1021 , coating the first portion with a covering coating having a surface tension less than or equal to a tension threshold.
[0112] In this step, the covering coating can be vapor-deposited on the side of the polarizer body provided with the arc-shaped structu...

The invention provides a polarizer, a display device and a preparation method of the polarizer. The polarizer comprises a polarizer body, an arc-shaped structure arranged on one side of the polarizer body; wherein the arc-shaped structure comprises an arc-shaped side surface, and the arc-shaped side surface is provided with a conduction groove. The display device includes: the polarizer; a display panel, wherein the polarizer is arranged on the display panel; and a coating adhesive layer coated on the display panel and connected with the arc-shaped structure of the polarizer. The arc-shaped structure is arranged on one side of the polarizer body, so that the coating adhesive layer can be smoothly diffused to the two sides along the arc-shaped structure, the conduction groove is formed in the arc-shaped side face of the arc-shaped structure, diffusion of the coating adhesive layer can be guided, the diffusivity of the coating adhesive layer is improved, the accumulation condition of the coating adhesive layer is effectively avoided, the thickness of the coating adhesive layer is more uniform, the coating adhesive layer and the polarizer are connected more tightly, and the situation of light leakage caused by bubbles is avoided.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a polarizer, a display device and a method for preparing the polarizer. Background technique [0002] With the continuous development of consumer electronics products, people have higher and higher demands for narrow bezels of screen modules, especially the reduction of the lower bezels has attracted widespread attention. However, the reduction of the lower frame will be accompanied by certain problems, such as light leakage. [0003] In the prior art, it is generally chosen to cover the side of the polarizer on the display panel with an adhesive layer, but in general, due to the poor diffusion performance of the adhesive layer, problems are likely to occur at the junction with the polarizer. Contents of the invention [0004] In view of this, the purpose of the present application is to propose a polarizer, a display device and a method for preparing the polarizer ...
