Abstract

A transflective cholesteric liquid crystal display (Ch-LCD) is demonstrated by using the image-enhanced reflector (IER) film on the top of the transmissive region to provide the similar paths for both transmissive and reflective light, thus, to display same image color in any ambience, improving the image quality. For full color display, the inkjet printing was applied and the patterned Ch-LC droplet was successfully deposited on the substrate. Thus, full-color Ch-LCD can be fabricated by IJP.
