New Configuration of a Transflective Liquid Crystal Display Having a Single Cell Gap and a Single Liquid Crystal Mode

We report on a new tranflective liquid crystal display (LCD) mode having a single cell gap and a single LC mode. For this display mode, a low twisted nematic liquid crystal cell, having the twist angle of 60°, is used for both transmissive and reflective applications. The measured electro-optic characteristics of our transflective cell agree well with numerical simulation results. It is found that the transmittance and the reflectance become identical to each other in the high voltage regime. The new transflective configuration is useful for mobile LCD applications.
