摘要:
The present disclosure provides a pixel driving circuit, including a first pixel driving unit and a second pixel driving unit. The first pixel driving unit includes a first driving transistor, a first storage capacitor and a first driving control unit. The first driving control unit is configured to apply a jumping voltage onto the data voltage at a first compensation stage, so as to perform jumping compensation on a threshold voltage of the first driving transistor. The second pixel driving unit includes a second driving transistor, a second storage capacitor and a second driving control unit. The second driving control unit is configured to apply a jumping voltage onto the data voltage at a second compensation stage, so as to perform jumping compensation on a threshold voltage of the second driving transistor and control the second light-emitting element to emit light.
