Stability of hydrogenated amorphous silicon TFT driver

Abstract Gate and data drivers are essential for driving active matrix display. In this study, we integrate drivers with a‐Si:H to develop a compact, better reliability and cost effective display. We design and fabricate drivers with conventional a‐Si:H thin film transistors (TFTs). The output voltages are investigated according to the input voltage, temperature and operation time. Based on these studies, we propose here a new driver to prevent gate line from the floated state. For the external coupled voltage fluctuation, the proposed driver shows better stability.
