Transflective TFT-LCDs with high optical performance

— In order to reduce panel cost, reduce power consumption, and minimize thickness, a single panel with dual functions for high‐transmissive main displays and high reflective sub‐displays is becoming the trend. Two novel RGB‐W transflective 1.9‐in. a‐Si TFT LCDs have been developed to meet the requirements. By using the traditional seven‐mask dual‐cell‐gap structure, novel transflective tRGB‐t/rW TFT LCD and tRGB‐rW TFT‐LCD panels were fabricated with high transmittance and high reflectance, respectively. The optical clarity is excellent in both dark and bright conditions. Their superior optical performance is attributed to the high‐efficiency “transflective white” subpixel or “reflective white” subpixel.
