High Performance Full Color Cholesteric Liquid Crystal Display with Dual Stacking Structure

摘要

A 10.4-inch full color cholesteric liquid crystal display (ChLCD) with high reflectivity and high resolution by dual stacking is demonstrated. This display consists of two cholesteric liquid crystal (ChLC) panels with the same chirality ChLC but separated by a layer of half-wave plate material allow the reflection of both components of incident circularly polarized light in a single display. Each individual ChLC panel is fabricated by the development of the pixelized vacuum filling (PVF) technique. The reflectivity of our ChLCD is about 26% with 100 ppi resolution and 3-bit color.
