Abstract

The invention provides a manufacture method of UV-resistant dye, comprising: providing an azo dye structure; providing a UV-resistant modifying group; and using the UV-resistant modifying group, in aliquid crystal dye mixed solution, to perform UV-resistant modification on the azo dye structure so as to obtain UV-resistant modified azo dye. The invention also provides a coating-type dye polarizer. The manufacture method of the UV-resistant dye and the corresponding coating-type dye polarizer have the advantage that by coating the coating-type dye polarizer with UV-resistant dye capable of absorbing UV, the coating-type dye polarizer is avoided being influenced by UV irradiation.

Description

Technical field [0001] The invention relates to the field of polarizer production, in particular to a method for preparing UV-resistant dyes and a corresponding coating type dye polarizer. Background technique [0002] With the development of science and technology, people’s requirements for display devices are getting higher and higher. As an important component of liquid crystal displays, polarizers, whose heat resistance, humidity resistance and UV resistance are essential to the reliability of liquid crystal displays of. [0003] Traditional iodine-based polarizers have been gradually replaced by new coating-type dye polarizers because of their poor resistance to moisture and oxygen. Among them, the dye-type polarizer uses dichroic dyes with excellent moisture resistance to replace the corresponding polarizer iodine, which effectively improves the moisture resistance of the corresponding liquid crystal display. In addition, due to its light and thin appearance, simple product...
