Abstract
Disclosed are a gate driving circuit, a driving method thereof, and a display device which comprises the gate driving circuit. In the gate driving circuit, the Qnode in the nstage circuit is precharged when an output signal of a Qnode in a previous stage driving circuit and an output signal of a Qnode in a next stage driving circuit are both in a high-level state. Both the Q−1 node and the Qnode are at low levels when the gate driving circuit is in an All Gate On display state, and thus a possibility of current leakage from the Qnode can be substantially reduced.
