Abstract: A gate driving circuit includes a stage configured to output a scan gate signal based on a scan clock signal, a voltage of a first node, and a voltage of a second node, and to output a sensing gate signal based on, a sensing clock signal, the voltage of the first node, and the voltage of the second node. The stage includes: a first sensing circuit configured to select a gate line to be sensed based on a S1 signal or to determine a frame reset based on a S7 signal; a first inverting circuit configured to control the first sensing circuit base on the S7 signal; and a second sensing circuit configured to control the voltage of the first node using the first sensing circuit based on a S2 signal. The frame reset is determined based on a maximum frequency of a variable frame frequency.
