摘要

The reflective cholesteric liquid crystal display suffers from voltage-induced color shift and viewing angle-dependent color shift. In this paper, three solutions are presented to overcome these problems. First, four types of cholesteric liquid crystals were prepared and characterized to find the best mixture with the lowest voltage-induced color shift and reflectance reduction. Secondly, 5-primary (red, yellow, green, cyan and blue) cholesteric liquid crystals were prepared such that the color gamut and reflectance were enhanced. Finally, the viewing angle-dependent color shift was characterized and then compensated by adjusting their chromaticity by using red/green/blue LED light sources.
