摘要

An integrated a-Si: H thin-film transistors (TFTs) gate driver on array with both forward and backward scanning function is proposed. The single stage of the gate driver only consists of seven TFTs. The bi-direction scannable function is just realized by controlling the turning-on sequence of two input TFTs. Both scanning modes use the same driving TFT for pulling-up and pulling-down the output voltage and the same circuit unit for holding the low level. The proposed gate driver is fabricated in the 4.5 G TFT production line, and the measurements with the fabricated drivers verify the feasibility of the proposed driver.
