Abstract
This application proposes a pixel driving circuit and a display panel including an output module, a current control module, and a duration control module. The duration control module includes a first input unit and a first capacitor connected to each other. A second plate of the first capacitor is connected to a voltage control signal terminal. The voltage control signal terminal outputs a periodic lighting control signal during a light emitting stage. When the voltage control signal terminal is configured in a first voltage range, the output module is turned on, and when it is configured in a second voltage range, the output module is turned off.
