Abstract

The invention provides a preparation method of a coating type dye polarization component, wherein the coating type dye polarization component comprises a substrate; a polarization alignment film is arranged on the substrate; the preparation method comprises the following steps: heating a reaction vessel to a reaction temperature according to a hot bath method, maintaining the reaction temperature in the reaction vessel; placing a reaction monomer in the reaction vessel, stirring and fully dissolving, then standing for a first time interval; placing a dye in the reaction vessel, stirring and fully dissolving, then standing for the first time interval to obtain a polarization film solution; coating the polarization film solution on the polarization alignment film of the substrate by using a spin-coating method to obtain a polarization film; curing the polarization film through ultraviolet irradiation to obtain the coating type dye polarization component. The invention further provides a liquid crystal panel. The solution of the invention can improve a polarization degree of a polarizer and improve a contrast ratio of the liquid crystal panel.

Description

technical field [0001] The invention relates to the field of liquid crystal manufacturing, in particular to a method for preparing a coating-type dye polarizing assembly, and a liquid crystal panel with the coating-type dye polarizing assembly produced by the preparation method. Background technique [0002] The polarizer is a very important part of the LCD panel, which largely determines the key characteristics of the LCD panel, such as contrast, transmittance, brightness, thickness, etc. Among them, the dye-based polarizer absorbs dichroic organic dyes on PVA (polyvinyl alcohol), and stretches and aligns them to make it have polarized light performance. Dye-based polarizers have better resistance to high temperature and high humidity. Dye-based polarizers also include coated polarizers. Coated dye polarizer is a kind of polarizer with excellent reliability and can be thinned. One of the raw materials for the preparation of the coated dye polarizer is dye. [0003] Howe...
