A dual-gate + Z-inversion(DZi) driving method was proposed to reduce power consumption of thin-film transistor liquid crystal display(TFT-LCD).The power saving principle of DZi driving was researched,the structure design and circuit design were finished,35.6 cm(14 in) WXGA(1 366 RGB×768) samples were manufactured,and the power saving effect was measured and analyzed.As results,DZi can save TFT-LCD power consumption in effect,such as panel AVDDS power reduces 70%(191 mW) when display color-bar pattern.Moire phenomenon that appeared in DZi module was analyzed,and solutions were proposed.The research established a driving method and design reference for lower power consumption in TFT-LCDs and other displays.
