Abstract:
A GOA unit circuit is provided with an input sub-circuit configured to set a turn-on voltage to a first node and a turn-off voltage to a second node in response to an input signal and a first clock signal; a first pull-down sub-circuit, a pull-up sub-circuit, a first control sub-circuit, and a second control sub-circuit configured to set voltage levels of the first, the second, and a third nodes. The gate on array unit circuit also includes a first output sub-circuit to output a first output signal at the turn-on voltage triggered by a second clock in response to voltage levels at the first, second nodes and a second output sub-circuit to output a second output signal falling to the turn-off voltage triggered by the first clock and rising to the turn-on voltage triggered by the third clock in response to voltage levels at the first, third nodes.
