Abstract

The invention discloses a cholesteric-phase flexible liquid crystal display device and a preparation method of the cholesteric-phase flexible liquid crystal display device. The cholesteric-phase flexible liquid crystal 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, a liquid crystal mixture layer and a light mask plate. Ultraviolet light acts on the flexible liquid crystal display device through the light mask plate, the liquid crystal mixture layer is provided with a polymer wall of a special structure, and capsulation covering is conducted on liquid crystal molecules through the polymer wall formed through a polymerization reaction, so that the cholesteric-phase flexible liquid crystal display device is formed. Compared with display devices of other types, the cholesteric-phase flexible liquid crystal display device has the advantages of being low in power consumption, small in size, low in cost and the like, a capsulation flexible panel of cholesteric liquid crystals is formed in a special mode, the polymer wall has the specific structure, and the cholesteric-phase flexible liquid crystal display device has good photoelectric performance and display and mechanical overall performance.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a cholesteric phase flexible liquid crystal display device with a special structure and a preparation method thereof. Background technique [0002] Cholesteric liquid crystal material has helical structure and bistable characteristics, especially its reflective display performance, which is the key technology and material of flexible display technology. Its polymer stabilizes the display mode of cholesteric liquid crystal and improves the performance of cholesteric liquid crystal. The chemical stability promotes its application in the field of display. [0003] 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). Backlight, and 80% of the power consumption of the device is consumed on the backlight, so thi...
