A pixel driving circuit includes a driving control sub-circuit and a driving duration control sub-circuit. The driving control sub-circuit includes a first driving sub-circuit connected to a first node. The driving control sub-circuit is configured to be connected to an element to be driven. The driving control sub-circuit is configured to output a driving signal to drive the element to be driven to operate. The driving duration control sub-circuit includes a second driving sub-circuit connected to a second node. The driving duration control sub-circuit is configured to write a first voltage signal into the second node, write a third voltage signal into the second node, and transmit a second voltage signal to the first node in response to a voltage variation at the second node to stop the first driving sub-circuit from outputting the driving signal, so as to control an operating duration of the element to be driven.
