Abstract
A unitary type of a transflective liquid crystal display (LCD), having the same optical efficiency in both the transmissive (T) part and the reflective (R) part, is developed using an in-cell patterned (IP) retarder fabricated directly on a wire grid (WG) plate in a twisted-nematic geometry. The WG plate is used for a substrate and served as a polarizer in the T region and a reflector in the R region. In this unitary transflective LCD, it was found that the high optical efficiency and the fast response are easily achieved in a single driving scheme since the electro-optical disparity between the transmittance and the reflectance is intrinsically eliminated.
