高性能反射型ＬＣＤの技術開発および実用化

抄録

We review our developed reflective and transflective LCD technologies, which provide high quality color image, low power consumption and good visibility. Our reflective LCD technology, based on a new twisted-VA mode and micro reflective structures, had excellent optical properties such as high reflectance, high contrast ratio and high NTSC ratio. Flicker-less 1Hz driving was achieved with applying IGZO-TFT technology and optimal panel designs. Considering the visibility in dark environments, a novel transflective LCD technology was developed based on the reflective technology. We successfully applied those technologies into LCD products the mass production of which has been started since 2020.
