AI Technical Summary

Technical Problem

The existing photoalignment process of cholesterol liquid crystal displays has the problem of uneven reflectivity, which leads to visual defects and poor picture performance, especially the uneven reflectivity at different viewing angles.

Method used

Multiple selective light reflection modules are employed, each containing a display layer and a photoalignment layer. The alignment direction of each photoalignment layer is precisely controlled through photoalignment technology, so that the pixels of different selective light reflection modules have different alignment directions. The light absorption layer is used to improve the image contrast, and different alignment units are formed on the photoalignment layer through photomask blocking technology.

Benefits of technology

It effectively improves the reflectivity uniformity of display devices under different viewing angles, expands the potential of high-resolution and wide-viewing-angle display applications, and improves image contrast and stability, while avoiding moiré patterns.

Abstract

A display device comprises a plurality of selective optical reflection modules arranged in a stacked mode. The selective optical reflection modules each comprise a display layer and a photo-alignment layer. The display layers each comprise a plurality of pixels, and the photo-alignment layers are disposed on the corresponding display layers. The photo-alignment layer of one selective optical reflection module among the plurality of selective optical reflection modules provides an alignment direction for the pixels, and the photo-alignment layer of another selective optical reflection module among the plurality of selective optical reflection modules provides another alignment direction for the pixels. Said alignment direction is different from said another alignment direction. Therefore, the uniformity of reflectivity at different viewing angles can be improved.
