A novel method to realize the good performance of transflective LCD is indicated. In one pixel, two LTPS (Low‐temperature poly‐Si) TFT devices control the optical intensity of the transmissive and reflective regions respectively. We call this way as double gamma method (DGM). Uni‐gap transflective LCD attached the DGM will have both merits of simplifying processes and good legibility. Meanwhile, we show the experimental results of optical characteristics with uni‐gap homeotropic panel design. It obviously shows that high contrast ratio and wide viewing angle have been achieved.
