  • Publication number: 20250149006
    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.
