Problems solved by technology

Reinforcement placement technology is to place metal solder joints at the fixed points of the printed circuit board PCB, which belongs to the antistatic of the circuit category; the technology of adding metal minerals to the glass film is to add a certain metal film on the surface of the glass film, such as ITO film. Improve the performance of the glass film, however, the antistatic ability of the liquid crystal display product obtained in this way can only reach about 8kv at most, its antistatic ability is not strong enough, the process is complicated, and it is difficult to meet the needs of liquid crystal display products

Embodiment 1

[0027] This embodiment provides a method for preparing a polarizer. The preparation method of the polarizer is to apply an adhesive with a conductive substance on at least one side of the first support layer close to the polarizer, one side or both sides of the polarizer And at least one or both sides of the second supporting layer; or, further adding conductive substances to the surface of the above-mentioned layers while performing surface treatment, so as to improve the antistatic ability of the liquid crystal display using the polarizer.

[0028] Specifically, in the preparation method of the polarizer, it includes the steps of sequentially stacking the protective layer, the first support layer, the polarizer layer, the second support layer and the release film layer through an adhesive. Conductive substances are pre-added in the adhesive between at least one contacting surface of the first supporting layer and the polarizing layer, the polarizing layer and the second suppo...

Embodiment 2

[0048] This embodiment provides a display substrate, including the polarizer in Embodiment 1.

[0049] In this embodiment, the display substrate can be a color filter substrate or an array substrate, liquid crystal is dripped on the array substrate, and the process of combining the color filter substrate and the array substrate (Cell 1) forms a liquid crystal display, the embodiment The polarizer in 1 is attached to the side of the color filter substrate or array substrate relatively away from the liquid crystal.

[0050] The display substrate using the polarizer in Example 1 has better antistatic ability, ensures the display quality of the liquid crystal display screen, and has a high product yield.

Embodiment 3

[0052] This embodiment provides a display device, including the display substrate in Embodiment 2.

[0053] The display device may be any product or component with a display function, such as a liquid crystal panel, electronic paper, a mobile phone, a tablet computer, a television set, a monitor, a notebook computer, a digital photo frame, a navigator, and the like.

[0054] The display device using the display substrate in Embodiment 2 has better antistatic ability, ensures the display quality of the liquid crystal display screen, and has a high product yield.

Abstract

The invention belongs to the technical field of displaying, and particularly relates to a manufacturing method of a polaroid, the polaroid, a display substrate and a display device. The manufacturing method of the polaroid includes the steps that a protective layer, a first supporting layer, a polarized light layer, a second supporting layer and a release film layer which are sequentially overlapped are bonded through adhesives, wherein the adhesives smeared on at least one connecting surface between the first supporting layer and the polarized light layer, between the polarized light layer and the second supporting layer as well as between the second supporting layer and the release film layer are added with conductive matter in advance. The manufacturing method of the polaroid is simple in process, and the anti-static effect of the manufactured polaroid is good.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a preparation method of a polarizer, a polarizer, a display substrate and a display device. Background technique [0002] Polarizer is the main component of Liquid Crystal Display (LCD for short), and has a direct impact on image quality. [0003] As an electronic product, a liquid crystal display device will inevitably be damaged by electrostatic discharge, and the damage of static electricity to a liquid crystal display (Panel) is very direct and obvious. In the manufacturing process of the liquid crystal display device, the antistatic performance of the polarizer attached to the outer surface of the liquid crystal display is particularly important, which is directly related to the performance and yield of the final liquid crystal display device. [0004] The existing mainstream anti-static liquid crystal display generally adopts the technology of strengthening th...
