Zusammenfassung:A display panel includes a scan driving circuit. The scan driving circuit includes multiple shift-registers coupled in serial. At least one of the shift-registers includes a control circuit, a pumping circuit and an output circuit. The control circuit controls a voltage at a first control node according to a start-up signal and controls a voltage at a second control node according to a reset signal. The pumping circuit is coupled to the control circuit for pumping up the voltage at the first control node. The output circuit is coupled to the pumping circuit and the control circuit for outputting multiple gate driving signals at multiple output nodes in response to the voltage at the first control node. One of the output gate driving signals is provided to a following stage of shift-register as the start-up signal thereof.
