摘要

This work presents a new gate driver circuit based on hydrogenated amorphous silicon thin-film transistors (a-Si:H TFTs) with simple structure for liquid-crystal displays (LCDs). The circuit uses the capacitors and colck signals to periodically couple the gate node of the driving TFT to a low voltage level to enhance the stability of the presented gate driver circuit. Moreover, the dock signal drives the pull-down TFT to suppress the threshold voltage shifts. Simulation results verify that the output waveforms are sequential and uniform. Therefore, the presented gate driver circuit is applicable to slim-bezel TFT-LCD applications.
