Abstract
A gate driving circuit and a display panel with the gate driving circuit are provided. The gate driving circuit includes shift registers. The shift registers are configured to respectively provide scan signals to gate lines of a display panel. One of the shift registers includes a pre-charge unit, a pull-up unit and a reset unit. The pre-charge unit is coupled to a first node and is configured to output a pre-charge signal to the first node. The pull-up unit is coupled to the first node and a second node and is configured to output one of the scan signals to the second node. The reset unit is coupled to the first node and the second node and is configured to receive a reset signal. A voltage level of the reset signal switches after the gate driving circuit scans the gate lines sequentially in a frame period.
