Abstract
A gate driving circuit drives a plurality of gate lines arranged in a display panel. The gate driving circuit includes a shift register having at least two stages of shift register units, and a gate enable circuit. Each shift register unit includes a gate signal output terminal configured to output a gate signal. The gate enable circuit includes a plurality of gate enable units. Each gate enable unit corresponds to one of the shift register units and includes an input terminal connected to the gate signal output terminal of the corresponding shift register unit, an output terminal connected to a corresponding one of the gate lines, and an enable signal input terminal configured to receive an enable signal. Each gate enable unit is configured to selectively output the gate signal of the corresponding shift register unit to the corresponding gate line based on the state of the received enable signal.
