Bendable liquid crystal display panel and preparation method thereof

Abstract

The invention discloses a bendable liquid crystal display panel and a manufacturing method thereof. The display panel comprises a first substrate and a second substrate which are oppositely arranged,and a liquid crystal layer positioned between the first substrate and the second substrate. The liquid crystal layer comprises first liquid crystal molecules located on one side of the first substrate, second liquid crystal molecules located on one side of the second substrate and third liquid crystal molecules located between the first liquid crystal molecules and the second liquid crystal molecules. The first liquid crystal molecules have a first pre-tilt angle, the second liquid crystal molecules have a second pre-tilt angle, the second pre-tilt angle is larger than the first pre-tilt angle, and the third liquid crystal molecules are consistently inclined towards the pre-tilt direction adjacent to the second liquid crystal molecules. According to the display panel, dark fringes are avoided when the display panel is bent, and the quality of the display panel is improved.

Description

technical field [0001] The present application relates to a display device, in particular to a bendable liquid crystal display panel and a preparation method thereof. Background technique [0002] With the professionalization of e-sports and the development of many international competitions, the e-sports market is gradually booming. The experience requirements of professional players for competitive games have also been continuously improved. Among them, the curved gaming screen has become a hot new model because of the immersive experience it provides. However, during the process of the screen being curved, dark clusters will appear on the VA display which will affect the display quality. [0003] Through analysis and theoretical simulation, the real cause of dark clusters in VA-type displays is that the liquid crystal molecules near the substrate have the same pretilt angle. After bending, the liquid crystal molecules in the middle are subjected to different viscous for...

AI Technical Summary

Problems solved by technology

refer to Figure 1B During the bending process of the display panel, the liquid crystal molecules close to the two substrates give the middle liquid crystal intermolecular forces in different directions, so that the liquid crystal molecules in the middle of the dislocation are in a chaotic or vertically arranged state, so that the light cannot be normal. pass

From a macro point of view, the chaotic liquid crystal part makes the display panel produce irregular dark clusters, which affects the quality of the panel
