Abstract: The present application discloses a pixel driving circuit and a display panel. Before the charging module charges the pixel electrode, the present application releases the voltage of the pixel electrode by means of the discharging electrode. Therefore, it is possible to avoid that the voltage of the pixel electrode is charged to a target value after the residual voltage on the pixel electrode needs to be canceled during charging the pixel electrode by the charging module. As a result, the power consumption of the pixel electrode during the charging/discharging process can be reduced, and the charging/discharging time period of the pixel electrode can be reduced.

Abstract: A driving method of a gate driver on array (GOA) circuit, a gate driver, and a display panel are provided to reduce a time period of a gate signal rising from a first low potential to a first high potential, so that pixel units can be charged faster and earlier and a charging rate of the pixel units can be improved. In addition, a time period for the gate signal to fall from the first high potential to the first low potential can be reduced. As a result, the pixel units can be turned off faster and earlier, so that a risk of wrong charging of the pixel units is reduced.
