An Integrated a-Si∶H TFT Gate Driver for WXGA TFT-LCD

An integrated a-Si∶H TFT gate driver for 14.1inch WXGA(1280×RGB×800) TFT-LCD has been developed.A major feature of the driving circuit is that no TFT device suffers from a successive DC bias.This alleviates significantly the shifts of threshold voltages of the TFTs,making the driver highly reliable in a long term.Experimental results show that the proposed a-Si∶H TFT gate driver is suitable for TFT-LCD application.
