A new gate driver has been designed and fabricated by amorphous silicon (a-Si) technology. With utilizing four clock signals in the design of gate driver on array (GOA), the pull-up transistor has ability for both output charging and discharging, and layout size of the proposed gate driver can be narrowed for bezel panel application. Moreover, lower duty cycle of clock signals can decrease static power loss to further reduce the overall power consumption of the proposed gate driver. The scan direction of the proposed gate driver can be adjusted by switching two direct control signals to present the reversal display of image. The proposed gate driver has been successfully demonstrated in a 4.5-inch WVGA (480 x RGB x 800) TFT-LCD panel and passed reliability tests of the supporting foundry.

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.
