Abstract
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.
