Abstract

A pixel driving circuit includes: a dual-gate driving transistor, a compensation sub-circuit, a data writing sub-circuit and a light-emitting control sub-circuit. A first electrode of the dual-gate driving transistor is coupled to a first voltage terminal. The compensation sub-circuit is configured to write a compensation signal of a compensation signal terminal into a first gate of the dual-gate driving transistor in response to a signal of a first control signal terminal. The data writing sub-circuit is configured to write a data signal of a data signal terminal into a second gate of the dual-gate driving transistor in response to a signal of a second control signal terminal. The light-emitting control sub-circuit is configured to cause a second electrode of the dual-gate driving transistor and a first electrode of a light-emitting element to be connected or disconnected in response to a signal of a light-emitting control signal terminal.
