Abstract
We have developed a transflective TFT‐LCD device based on IGZO TFT(thin film transistor) using GIP and Demux driving circuit. The average flicker is −62.35dB when in reflective mode driving in 1Hz while −55dB in transmissive mode driving in 60Hz. The flicker and the visual effect still performance well after RA(reliability analysis) test. The flicker after RA test almost unchanged comparing with the LCD without RA test. The average contrast ratio is 24.9 in reflective mode while 33.4 in transmissive mode. The power consumption average reduced by 40% in 1Hz reflective mode contrasting to 60Hz in transmissive mode while in black, white, red, green, blue, grey, flicker, crosstalk, checkpixel image. We proved the power consumption can be reduced by even more if IC is well designed. The transflective LCD device supports 256 grey.
