Ink jet cholesterol LCD/ color filter and preparing method thereof

Abstract

This invention provides one spray cholesterol LCD or color filter and its process method, which comprises orderly upper baseboard, upper match layer, down match layer, down baseboard and upper transparent electrode between upper baseboard and upper match layer and down transparent electrode and absorptive layer between down match layer and down baseboard, wherein, it uses spray type to spray red, blue and green materials cholesterol into down match layer each block areas to form pixel to lower the adhesive degree into required range to get one cholesterol LCD.

Description

technical field [0001] The invention relates to a liquid crystal display and a color filter, in particular to a full-color cholesteric liquid crystal display with high display quality produced by a cholesteric liquid crystal inkjet method and a color filter with high light extraction efficiency produced by a cholesteric liquid crystal inkjet method. Background technique [0002] Cholesteric liquid crystal display has the bistable property (Bistability), liquid crystal molecules can exist stably in two states, it does not need continuous voltage to maintain the screen, and it has the effect of saving power, so the user only needs to supply voltage when updating the screen. Can. Compared with general reflective STN or TFT, cholesteric liquid crystal display can save power, so it is very suitable for any static screen display, including large displays (such as billboards, price lists), portable displays (such as electronic book electronic photo frame) and wrap-around display (...

AI Technical Summary

Problems solved by technology

However, the traditional color filter process is expensive and liquid crystals with high birefringence are not only difficult to obtain, but also more expensive than traditional single-frequency liquid crystals.
