Novel Shift Register Using Amorphous Silicon TFTs for Liquid Crystal Displays Application

Abstract

A new shift register has been successfully designed and integrated for a 3.8-inch WVGA (800xRGBx480) panel. With the proposed threshold voltage drop cancellation technique, output rise time can be substantially decreased by 24.6% for high resolution display application. Furthermore, the demonstrated panel shows almost no degradation after 500 hours operation.
