Patent ID: 11615738

Abstract:
A pixel driving circuit includes a driving control sub-circuit having a first driving sub-circuit and a time control sub-circuit having a second driving sub-circuit. The driving control sub-circuit is configured to: be connected to an element to be driven, write a first data signal into the first driving sub-circuit, enable the first driving sub-circuit to output a driving signal to drive the element to operate. The time control sub-circuit is configured to: write a second voltage signal and a second data signal into the second driving sub-circuit, write a fourth voltage signal into the second driving sub-circuit, connect the second driving sub-circuit to a third voltage signal terminal and the first driving sub-circuit. The second driving sub-circuit is configured to output a third voltage signal to the first driving sub-circuit to enable the first driving sub-circuit to stop outputting the driving signal to control operating duration of the element.
