Abstract

Transflective liquid crystal displays are highly desired for mobile devices because they can be operated either in transmissive mode, illuminated by backlight in dark ambient light conditions, or reflective mode, illuminated by ambient light in bright ambient light conditions. We developed a single-cell gap transflective display based on fringe-field switching. The display consists of transmissive and reflective subpixels whose operations are synchronized through polymer stabilization. This display has a high contrast ratio because the transmittance-voltage dependences of the two subpixels are similar (they are both in dark state at 0 V and in bright state at an applied voltage) and do not interfere with each other. It has the advantages of single-cell gap and no in-cell retarder and its manufacturing process is simple.
