A flexible liquid crystal display panel and its preparation method

Abstract

The present application discloses a flexible liquid crystal display panel and a manufacturing method thereof. The display panel includes: a first substrate and a second substrate oppositely arranged; a liquid crystal located between the first substrate and the second substrate layer; wherein, the liquid crystal layer includes first liquid crystal molecules on one side of the first substrate, second liquid crystal molecules on one side of the second substrate, and liquid crystal molecules on the first liquid crystal molecule and the second liquid crystal The third liquid crystal molecule between the molecules, the first liquid crystal molecule has a first pretilt angle, the second liquid crystal molecule has a second pretilt angle, the second pretilt angle is greater than the first pretilt angle, and the first liquid crystal molecule has a second pretilt angle. The three liquid crystal molecules are uniformly tilted towards the pretilt direction adjacent to the second liquid crystal molecule. When the display panel is bent, dark lines are avoided, 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...

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
