Problems solved by technology

[0007] In order to realize the use of cholesteric liquid crystals in flexible displays, it is necessary to encapsulate the liquid crystal molecules so that the liquid crystal molecules cannot flow freely and eliminate problems such as pressure points during flexible displays.
The usual solution is to coat the liquid crystal with a polymer dispersed liquid crystal method, but due to the irregular polymer network formed, the mechanical properties are not ideal, and the driving voltage is often high and many other problems.

Abstract

The invention belongs to the technical field of liquid crystal display and particularly relates to a flexible display device of a cholesteric liquid crystal capsule and a preparation method thereof. The flexible display device comprises a light absorption layer, a first flexible substrate, a second flexible substrate, a first electrode, a second electrode, a first orientation layer, a second orientation layer and a liquid crystal mixture layer with a special structure polymer wall. The invention further provides the preparation method of the flexible display device of the cholesteric liquid crystal capsule with the special regular structure. According to the method, a light mask plate with a special shape is utilized to induce a polymer monomer to undergo a polymerization reaction through light so that the polymer wall is formed, liquid crystal molecules are subjected to capsulation wrapping, the polymer wall is formed by a plurality of regular triangular truss structures and is stressed evenly and stable in structure due to the shape, mechanical performance of the flexible display device is remarkably improved, display performance is also improved, and accordingly comprehensive performance of the flexible display device is improved.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a flexible display device of a cholesteric liquid crystal capsule and a preparation method thereof. Background technique [0002] At present, LCD products are mainly transmissive LCDs, such as twisted nematic liquid crystal display (TN-LCD), super twisted nematic liquid crystal display (STN-LCD) and thin film transistor liquid crystal display (TFT-LCD), transmissive liquid crystal display A backlight must be used, and 80% of the power consumption of the device is consumed on the backlight, so this type of product generally consumes a lot of power, and does not give full play to the advantages of low power consumption of liquid crystal display devices. In recent years, reflective liquid crystal displays that do not use a backlight source, have low power consumption, and are light in weight have received more and more attention from people.
