LOW-POWER TECHNOLOGIES FOR THIN-FILM-TRANSISTOR COLOR LIQUID-CRYSTAL DISPLAYS

As a most favorable flat panel display for notebook Personal Computers (PCs), 23 similar to 26 cm-diagonal Thin Film Transistor (TFT) color Liquid Crystal Displays (LCDs) quickly developed a worldwide volume ma rket several years. Since the debut in the notebook PC market, portabi lity features such as weight, thickness and power consumption have bee n continuously improved. Among them, power consumption has been primar ily demanded for achieving longer battery life. The recent TFT-LCD mod ule power consumption far notebook PCs decreased to around 3 W, which is actually less than 1/3 of the first version. This paper describes t he past and future trends in the low-power consumption technologies fo r TFT-LCD modules of notebook PCs.
