Abstract:
Embodiments may be directed to a gate driving circuit. The gate driving circuit includes a pre-charge unit, a pull-up unit, a boosting unit, and a discharge unit. The pre-charge unit pre-charges a first node in response to a first input signal. The pull-up unit outputs a first clock signal as a gate driving signal in response to a first node signal of the first node. The boosting unit boosts the first node signal of the first node in response to the first node signal and the first clock signal. The discharge unit discharges the first node to a gate-off voltage level in response to a second input signal and a second clock signal.
