Design and fabrication of transflective cholesteric LCD with image enhanced reflector

Abstract

A novel transflective liquid crystal display is demonstrated by using cholesteric liquid crystal as a LC layer and an image-enhanced reflector (IER) on the top of the transmissive sub-pixel, providing the similar paths for both reflected and transmitted light, and two circular polarizers laminated on the upper and rear substrates. An extended IER (EIER) is applied to enhance the brightness and CR. As a result, Ch-LCD displays the same image color in any ambience, thus greatly improve the image quality of the transflective cholesteric LCD.
