    Abstract: A pixel driving circuit includes a data writing sub-circuit, a driving sub-circuit, and a control sub-circuit. The data writing sub-circuit is configured to: in response to a first scanning signal and a third scanning signal, write a first data signal into the driving sub-circuit; and in response to a second scanning signal and the third scanning signal, write a second data signal into the driving sub-circuit. The control sub-circuit is configured to, in response to an enable signal, connect a driving transistor to a first power supply voltage signal terminal and an element to be driven. The driving sub-circuit is configured to: according to the first data signal and a first power supply voltage signal, output a driving signal; and according to the second data signal and the first power supply voltage signal, control an operating state of the element to be driven.
