Design of Gate Driver Circuit Using a-Si:H Thin-Film Transistors with Bootstrapping Structure for High-Resolution Displays

Abstract

This work proposes a novel hydrogenated amorphous silicon thin-film transistor (a-Si:H TFT) gate driver circuit with a bootstrapping structure to shorten the falling time of output waveforms. The driving capability of the proposed circuit is improved without increasing the aspect ratio of driving TFT owing to the enlarged gate voltages by bootstrapping structure. The falling time of output waveforms is reduced by 20% compared to that of conventional gate driver circuit.
