Abstract

The invention discloses a full-color reflection type smectic liquid crystal display device with high contrast, which comprises a reflecting layer. A first dye liquid crystal hybrid display module, a second dye liquid crystal hybrid display module and a third dye liquid crystal hybrid display module are orderly superposed on the reflecting layer; and a first liquid crystal display module is superposed on the third dye liquid crystal hybrid display module. The full-color reflection type smectic liquid crystal display device with the high contrast has the advantages of rich color display effects,high screen reflectivity, white / black contrast of over 6:1, multistable characteristic, low energy consumption, high image refreshing speed and good environmental protection performance.

Description

technical field

[0001] The invention relates to a display device, in particular to a reflective smectic liquid crystal display device with high contrast and full-color display. Background technique

[0002] Traditional smectic liquid crystal display devices generally have a double-layer or triple-layer structure, see the PCT patent application document with the international application number PCT / GB2005 / 003705. Taking the three-layer structure as an example, each layer structure is composed of upper and lower substrates and a mixed layer between the upper and lower substrates. The mixed layer is composed of dichroic dyes and liquid crystals. The dichroic dyes added to each layer are different, and the three layers showing cyan, magenta, and yellow are stacked on top of each other and set on a white reflective plate to form the final display device. Due to the color combination on the three-layer structure, the conventional display device can realize the final display of v...
