A Simple Transflective LCD for Mobile Applications

A double-cell-gap transflective liquid crystal display (TR-LCD) based on 63.6$^{circ}$ twisted nematic mode is proposed. With only one uniaxial positive A-film in transmissive region, this normally black TR-LCD exhibits several attractive features, such as high optical efficiency, low operation voltage, acceptable viewing angle, and good cell gap tolerance. Moreover, the electro-optical characteristics of reflective and transmissive regions match with each other well. Its fabrication process is fairly simple and it is suitable for mobile applications.
