Abstract

Provided is a pixel driving circuit configured to provide a signal to a to-be-driven element. The pixel driving circuit includes: a current control sub-circuit, configured to transmit a current signal; a time length control sub-circuit, configured to transmit a time signal; and an output sub-circuit, electrically connected with the time length control sub-circuit and the current control sub-circuit, respectively; where the time length control sub-circuit is further configured to control the output sub-circuit to be turned on or off based on the time signal; the output sub-circuit is configured to, when turned on, control a current applied to the to-be-driven element based on the current signal, where duration of two adjacent turn-ons of the output sub-circuit is same and duration of two adjacent turn-offs of the output sub-circuit is same.
