Design of a universal a-Si TFT LCD controller for UXGA class

摘要

We present a universal a-Si (amorphous-Silicon) TFT (Thin Film Transistor) LCD (Liquid Crystal Display) controller of UXGA (Ultra eXtended Graphics Array, resolution: 1600 x 1200) class that can display the full screen of a LCD panel with lower or higher resolution of video sources such as NTSC,VGA,SVGA,XGA,SXGA,and UXGA. The proposed controller includes a new image scaler that can interpolate a new line data and decimate an original line data.
