Abstract
By building an image-enhanced reflector above the transmissive region of liquid crystal cell, the transmissive light can follow the similar path with ambient light that both reflective and transmissive portions can achieve high optical efficiency, same response time and color saturation. Furthermore, only single retardation film is required in this transflective color TFT-LCD, and ambient light and backlight utilization ratio can be increase to 68% and 24% respectively. With image-enhanced reflector built in, a high image performance display under both bright and dark ambience can be accomplished.
