Problems solved by technology
[0006] The development of thinning is a very important development trend of electronic products. With the current structure of polarizers, it is difficult to greatly reduce the thickness and meet the needs of thinner and thinner. In addition, iodine-based polarizers generally have the phenomenon of blue light leakage. The reason is that Iodine-based polarizers are difficult to completely absorb blue light with strong energy due to iodine dyes, and some blue light will directly pass through the polarizer to form incompletely polarized blue light, resulting in blue light leakage from the polarizer

Abstract
The invention discloses a manufacturing method of an anti-scratch graphene polarizer. According to the manufacturing method, a hardened resin layer is used as a protecting layer for a graphene film; surface hardening processing is performed on the surface of the graphene film through the hardened resin, thereby improving scratch resistance of the graphene polarizer, preventing graphene layer damage by scratch with an external object, sustaining performances such as integrity, high conductivity and low moisture permeability of the graphene layer, and further improving strength and weathability of the graphene polarizer.
Description
technical field [0001] The invention belongs to the technical field of polarizers, and in particular relates to a method for manufacturing an anti-scratch graphene polarizer. Background technique [0002] Polarizer is one of the indispensable components in the liquid crystal display field, and its purpose is to convert light into linearly polarized light. Under the control of an external electric field, the liquid crystal molecules are twisted to different degrees, resulting in light and dark changes, and then through the color filter, the screen can present colorful pictures. With the development of various liquid crystal products such as liquid crystal displays, notebook computers, and car displays, the demand for polarizers is also increasing. [0003] The existing polarizer is mainly composed of a release film, a pressure-sensitive adhesive layer, a PVA film, a TAC film, and a PET film, among which the PVA film plays a polarizing role; the TAC film is a protective layer...
