Abstract

We designed 10bit source driver LSI, then the high color depth and the low power consumption are realized thru it. It is adopted mini-LVDS receiver with high speed data transmission and good data recovery performance, Hybrid type DAC to reduce decoder size and OP-AMP with low power consumption and high slew rate. In addition we show our results of the 10-bit gray scale TFT-LCD source driver for 42inch diagonal size and WXGA resolution TFT-LCD TV applications.
