Transflective Liquid Crystal Display with Pi-Cell
We present results of optical simulation of a single cell gap transflective liquid crystal display with pi-cell that has two stable states which are parallel aligned LC state and 180 degrees twisted LC state. Here, the parallel aligned LC state is used for transmissive region coupled with back-light source and operated by horizontal field. On the other hand, the 180 degrees twisted LC state is used for reflective region coupled with sunlight or ambient light and operated by vertical field. The simulation shows that very excellent optical dispersion in both dark and bright states are exhibited.
