Abstract:
A pixel driving circuit includes a driving control sub-circuit and a time control sub-circuit. The driving control sub-circuit includes a first driving sub-circuit. The first driving sub-circuit is configured to output a driving signal to drive an element to be driven to operate. The time control sub-circuit includes a second driving sub-circuit. The second driving sub-circuit is configured to output a third voltage signal to make the first driving sub-circuit stop outputting the driving signal, so as to control operating duration of the element to be driven.
