Abstract
A pixel driving circuit includes a driving sub-circuit and a control sub-circuit. The driving sub-circuit is coupled to a data signal terminal, a scan signal terminal, a first power supply voltage terminal, an enable signal control terminal and an element to be driven, and the driving sub-circuit is configured to, in response to an enable signal, transmit a generated driving signal to the element to be driven, and control a current path transmitting the driving signal to be turned on and off. The control sub-circuit is coupled to the enable signal control terminal, and the control sub-circuit is configured to, in response to a signal received at the control signal terminal, transmit a signal received at a first enable signal terminal or a signal received at a second enable signal terminal to the enable signal control terminal.
