Example Embodiment

[0031] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The embodiments of the present invention are used to explain the present invention, but not as a limitation of the present invention.

[0032] Such as figure 1 As shown, a method for encapsulating a cholesteric flexible display is illustrated. The flexible display device part includes: a light-absorbing layer 01, a first flexible substrate 10, a second flexible lower substrate 20, a first electrode 30, a second electrode 40, a first The alignment layer 50, the second alignment layer 60, the liquid crystal molecules 71, the polymer precursor 72, and the polymer wall 73. The encapsulation of the flexible liquid crystal display device requires a photomask 80 and photopolymerization conditions, that is, a certain intensity of ultraviolet light 90.

[0033] Both the first electrode 30 and the second electrode 40 are transparent electrodes ...

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.
