Liquid crystal display and manufacturing method thereof

Abstract

The invention provides a liquid crystal display and a manufacturing method thereof. The manufacturing method of the liquid crystal display includes the steps: providing an upper substrate and a lowersubstrate; arranging a spherical shock insulator between the upper substrate and the lower substrate; connecting the shock insulator to the upper substrate and the lower substrate in a chemical bond mode or physical adhesion mode. By the manufacturing method, when the manufactured liquid crystal display deforms in a bending manner, the shock insulator cannot be broken or break away from the substrates, the thickness of a liquid crystal box is uniform, flexible display can be implemented, and the quality and the production yield of the flexible liquid crystal display are improved. The liquid crystal display manufactured by the manufacturing method has the advantages that the shock insulator cannot be broken or break away from the substrates, the thickness of the liquid crystal box is uniform, and flexible display can be implemented.

AI Technical Summary

Problems solved by technology

Flexible liquid crystal displays usually need to be bent and deformed during the production process or use process. When bending and deforming, the upper and lower substrates cannot achieve the same curvature deformation of the two substrates due to the adhesion of the frame glue, resulting in the deformation of the flexible liquid crystal display in the middle area and the edge area. The degrees are different. In the middle area, the flexible liquid crystal display is severely deformed. Due to the extrusion effect, the photolithographically formed spacer (PS) in the liquid crystal cell is broken and fails under heavy pressure, which makes the thickness difference of different areas in the liquid crystal cell significantly different, resulting in the display The display is abnormal, and the further impact is that when the deformation of the flexible liquid crystal display recovers, because the spacer has been damaged, it cannot support the normal thickness of the liquid crystal cell, resulting in poor gravity display

If a deformable soft frame glue is used to solve the above problems, when the flexible liquid crystal display is bent and deformed, due to the limited degree of deformation of the soft frame glue, the problem of obvious change in the thickness of the liquid crystal cell will also occur; if If conventional hard silicon ball spacers are used to replace the existing spacers, the silicon ball spacers will move when the flexible liquid crystal display is bent and deformed, scratching the inner membrane surface of the liquid crystal cell, resulting in abnormal liquid crystal alignment. , resulting in an abnormal display
