Preparation method of plastic liquid crystal display screen

Abstract

The invention relates to a preparation method of a plastic liquid crystal display screen, comprising the following steps: cleaning a plastic conducting film; coating photosensitive glue; pre-baking the photosensitive glue; exposure; development; hardening; etching; eliminating the film; coating a directing layer; solidifying the directing layer; rubbing the directing layer; silk-screening frame glue; spraying powder; silk-screening conducting material; attaching and solidifying the film; cutting and splitting the film; filling liquid crystal; sealing the opening; electrically detecting the screen by eyes; and pasting the polarizer. In the invention, the plastic conducting film, the liquid crystal, the polarizer and PI frame glue are main materials for producing plastic LCD, thereby solvingthe problem that a rainbow appears on the ground color of the plastic LCD product. The transmittance of plastic LCD reaches the same level of glass LCD; by using the frame glue material, the adhesionproblem among the plastic conducting films is solved and the reliability of a plastic LCD frame is ensured; and based on technical adjustment and optimized combination of material, the contractilityproblem of the plastic film is solved and the pattern is prevented from being distorted.

Description

technical field [0001] The invention relates to a method for preparing a liquid crystal display, in particular to a method for preparing a plastic liquid crystal display. Background technique [0002] Since RCA invented the first liquid crystal display device in May 1968, although it has only been more than 40 years, liquid crystal display (LCD) technology has developed rapidly, and the product type has developed from the initial TN type to the current one. The TFT type, the application range of the product is getting wider and wider, from the initial calculator to the current LCD TV, more and more terminal displays use LCD as the real equipment, LCD is gradually replacing the traditional CRT display, LCD Up to now, ITO glass has been used as the substrate. Due to the characteristics of glass being fragile, not resistant to falling, and not bendable, some products have been limited and affected in the application of LCD. LCD is officially a new generation of LCD to make up ...
