Three-Outputs-Single-Stage Gate Driver on Array for Internal Compensation Method Applications

A gate driver on array circuit using hydrogenated amorphous silicon (a-Si:H) thin-film transistor (TFT) with three-outputs for internal compensation display has been proposed. The driver circuit could simultaneously generate both positive and negative outputs, and a delayed positive third output. The pre-charge node of the negative output could multi-couple which decreases the rising time. Moreover, while the two outputs are generated, the electric potential is maintained until generating the positive third output. The length of delay interval between the first two outputs and the third output could be simply adjusted.
