A new TN-ECB mode liquid crystal display is developed for reflective liquid crystal displays (RLCDs). This new TN-ECB mode has a larger cell gap and lower operating voltage than most recently developed RLCDs. It also has a small wavelength dispersion and has a good dark state at the low operating voltage. It is particularly suitable for reflective crystallineSi backplane CMOSAMLCDs. Key Words: TN-ECB; RLCD. Introduction Conventional reflective TN & STN LCDs 1 use 2 polarizers which leads to a loss of brightness. Moreover, they have intrinsic problems such as slow response speed, difficult grayscaling, low brightness and large parallax. Since the early years of LCD research, various schemes have been attempted to eliminate the rear polarizer 2-9 and to increase the response speed 10,11,12 . There is a recent push again for designing fast reflective LCDs (RLCDs) and LCLV 1318 . In particular, for the case of reflective displays based on CMOS on crystalline silicon, RLCD modes w...
