Abstract
A pixel driving circuit is provided. The pixel driving circuit includes an initialization circuit, a driving circuit, and a first light-emitting control circuit. A first terminal of the driving circuit is coupled to a power voltage terminal, a second terminal of the driving circuit is coupled to a light-emitting element via the first light-emitting control circuit. The initialization circuit is configured to write an initialization voltage to a control terminal of the driving circuit under control of an initialization control signal input from an initialization control line, so that the driving circuit brings a connection between the first and second terminals into a conducting state under control of the control terminal. The first light-emitting control circuit is configured to bring a connection between the second terminal and the light-emitting element into a conducting state under control of a first light-emitting control signal input from a first light-emitting control line.
