Polaroid and manufacturing methods of display panel and polaroid

Abstract

The invention provides a polaroid. The polaroid comprises a substrate and a polarizing film layer arranged on the substrate; the polarizing film layer comprises a plurality of unit polarizing film layers; the positions of the plurality of unit polarizing film layers on the substrate correspond to the positions of a plurality of display panels in a liquid crystal box; and the area of each unit polarizing film layer is less than or equal to that of the corresponding display panel. Correspondingly, the invention further provides a manufacturing method of the display panel by using the polaroid and a manufacturing method of the polaroid. The polaroid disclosed by the invention is applied to a liquid crystal box-forming technology, and the attaching number of times and the attaching time of the polaroid can be greatly reduced.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a polarizer, a method for manufacturing a display panel using the polarizer, and a method for manufacturing the polarizer. Background technique [0002] The manufacturing process of the liquid crystal display panel generally includes an array (Array) process, a liquid crystal cell (Cell) process and a module (Module) process. [0003] In the existing liquid crystal cell forming process, the liquid crystal cell formed after laminating the array substrate and the color filter substrate needs to be cut into a plurality of display panels according to a certain size, and after grinding, cleaning, etc. A layer of polarizer is attached to the upper and lower surfaces. This is because the cutting process of the glass (that is, the base material in the array substrate and the color filter substrate) uses a micro-knife wheel to cut into the brittle glass, and slides and splits...

AI Technical Summary

Problems solved by technology

[0003] In the existing liquid crystal cell forming process, the liquid crystal cell formed after laminating the array substrate and the color filter substrate needs to be cut into a plurality of display panels according to a certain size, and after grinding, cleaning, etc. A layer of polarizer is attached to the upper and lower surfaces. This is because the cutting process of the glass (that is, the base material in the array substrate and the color filter substrate) uses a micro-knife wheel to cut into the brittle glass, and slides and splits according to the effect of stress. , while the polarizer is not made of brittle materials, but is made of organic elastic materials, which cannot be cut by stress

That is, if the entire polarizer is first attached to the upper and lower sides of the liquid crystal cell and then cut into multiple display panels together with the entire polarizer and the liquid crystal cell, the cutting process of the glass cannot be completed (if rough cutting Cutting the display panel by cutting the polarizer will damage the glass)

That is to say, if the liquid crystal cell needs to be cut into n display panels, polarizers need to be attached 2n times, and it takes 5 to 10 seconds for each polarizer to be attached. It can be seen that when the number of times of attaching polarizers When it is more, it takes more time, and it also increases the workload of the operator
