Abstract
The present invention provides a gate driver on array circuit. The gate driver on array circuit comprises: multiple gate driver on array units connected in cascade. The n-th gate driver on array unit of the gate driver on array circuit comprises a (n−2)-th signal input terminal, a (n+2)-th signal input terminal, a clock signal first input terminal, a clock signal second input terminal, a first low-level input terminal, a second low-level input terminal, a first output terminaland a second output terminal. The n-th gate driver on array unit further comprises: a pulling-up driving unit, a pulling-up unit, a first to a third pulling-down unit. The present invention adds a second low-level signal, which uses the second low-level to decrease the voltage difference (V) between the gate and the source of the thin film transistor of the first output terminal, so that the leakage current of the thin film transistor is less and can be controlled precisely.
