Abstract
Embodiments of the present disclosure provide a resetting circuit, a shift register, a gate driving circuit and a driving method thereof, and a display device. The first switching sub-circuit, the storage sub-circuit, the controlling sub-circuit, and the second switching sub-circuit in the resetting circuit output a first level signal to a second terminal of the resetting circuit. When a scanning frequency of the gate driving circuit is switched, a resetting function may be implemented by the resetting circuit even if there is no resetting signal provided by a resetting signal terminal for resetting a part of outputting terminals of the gate driving circuit.
