Abstract:
A pixel driving circuit includes: a driving control sub-circuit configured to write at least a first data signal into a first driving sub-circuit in response to a first scanning signal and cause a driving transistor to output a driving signal to an element to be driven according to the first data signal and a first power supply voltage signal in response to an enable signal, and a time control sub-circuit configured to write at least a second data signal into a second driving sub-circuit in response to a second scanning signal and cause the second driving sub-circuit to be connected to a second power supply voltage signal terminal and the element in response to the enable signal. The second driving sub-circuit is configured to output a second power supply voltage signal to the element in response to the second data signal and a common voltage signal.
