Embodiment Construction

[0029] In order to have a further cognition and understanding of the features, purposes and functions of the present invention, the detailed description is as follows in conjunction with the accompanying drawings:

[0030] see figure 2 , which is a schematic diagram of a black and white cholesteric liquid crystal display in a preferred embodiment of the present invention. exist figure 2 Among them, the black and white cholesteric liquid crystal display 20 includes a substrate 21, the inner surfaces of which are respectively covered with a layer of transparent electrodes 22, and the inner surfaces of the transparent electrodes 22 are respectively formed with a layer of alignment layer 23. The alignment layer 23 is filled with cholesteric liquid crystals 24, in which diffused macromolecules 25 with branch-like bonds are distributed. Through the above embodiments, the diffused polymer 25 can disrupt the arrangement of the cholesteric liquid crystal 24, changing the original p...

Abstract

The present invention relates to black-white cholesterol LCD and its production process. Exposure technology is adopted to complete the light polymerization / phase separation manufacture process, and further to form polymer wall and polymer diffused to cholesterol LCD area. The present invention has short technological process, high mechanical strength of interval between LCD unit and high brightness and contrast of the black-white LCD.

Description

technical field [0001] The invention relates to a black-and-white cholesteric liquid crystal display and a manufacturing method thereof, in particular to a black-and-white liquid crystal display using cholesteric liquid crystal as a display medium and using an exposure technology to complete a photopolymerization / phase separation manufacturing process and a manufacturing method thereof. Background technique [0002] In recent years, flexible displays such as electronic paper and e-books are booming, and the commonly used display media include liquid crystal displays, electrophoresis displays, and electrochromism displays. , and electrolysis display (electrolysis display), etc. In the application of electronic paper, compared with other display media, cholesteric liquid crystal has better results in brightness and contrast, and has the advantages of being passively driven and easy to produce. [0003] The application of cholesteric liquid crystal to a display is disclosed in...
