Problems solved by technology

However, the results of the optical performance of two different reflection bands of cholesteric liquid crystals are not the same. The cholesteric liquid crystals with a smaller helical pitch (pitch) have a short wavelength, and the characteristics of the liquid crystal itself tend to form a focal conic texture state, but in the plane I

Abstract

The invention provides a cholesterol liquid crystal panel and a manufacturing method of the cholesterol liquid crystal panel. The cholesterol liquid crystal panel comprises a first substrate, a second substrate and cholesterol liquid crystals, wherein the second substrate and the first substrate are opposite and parallel to each other, and the cholesterol liquid crystals are arranged between the first substrate and the second substrate. A corresponding alignment film is selected for the cholesterol liquid crystal panel according to the helical pitch of the cholesterol liquid crystals. Compared with the prior art, different surface processing modes can be utilized for the cholesterol liquid crystal panel so as to be matched with cholesterol liquid crystals with different reflection wavebands, and thus the cholesterol liquid crystal panel can have a good penetrating effect in the planar state, moreover, the cholesterol liquid crystal panel has a good fog state in focalconictexture so as to achieve the shading effect, and the optical performance of the cholesterol liquid crystals is promoted.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to a cholesteric liquid crystal panel and a manufacturing method thereof. Background technique [0002] Cholesteric Liquid Crystal Display (Cholesteric Liquid Crystal Display) is a new display technology, even if the power supply to the control board is removed, the image will still remain on the display. Its image is comparable to reading on paper, not only has high contrast, but also has a wide viewing angle, and can maintain high readability in daylight. Specifically, the structure of materials used in cholesteric liquid crystals is similar to that of cholesterol molecules. In addition to pure cholesteric liquid crystals, the extension materials include nematic liquid crystals with optical active agents, or nematic liquid crystals with cholesteric liquid crystal molecules. Placing cholesteric liquid crystals on two horizontal substrates, without applying an electric field for...
