A reflective color TFT‐LCD with high image quality has been developed for mobile display tools. The optimized construction of normally white (NW) mode reflective twisted hybrid aligned nematic (RTHAN) cell with a single polarizer and the cell structure is the same as the conventional sandwich 90° TN cell. The productivity of the generation of low pretilt angle is achieved by the proposed single exposure method. In this work, we have studied an optical design of the reflective twisted HAN mode TFT‐LCD to research an optical element design to obtain high contrast ratio, fast response time, wide viewing angle, and low driving voltage.
A novel asymmetric compensation structure including one biaxial film and two hybrid discotic layers for the high transmittance through wide viewing angle performance improvement in A-OCB panel was discussed. We fabricated 15.0" XGA OCB panel and evaluated various electro-optical characteristics such as the transmittance-voltage, viewing angle and response time. In addition, we studied the LC capacitance-voltage characteristic in OCB mode and found that it was superior to that of other LC modes and helped its own fast response characteristic.
