Zusammenfassung:A pixel driving circuit, comprising a dual-gate drive transistor (210), a compensation sub-circuit (211), a data writing sub-circuit (212), and a light-emitting control sub-circuit (213). The dual-gate drive transistor (210) comprises a first gate electrode, a second gate electrode, a first electrode and a second electrode, and the first electrode of the dual-gate drive transistor is coupled to a first voltage end (VDD). The compensation sub-circuit (211) is coupled to a compensation signal end (Vcomp) and the first gate electrode of the dual-gate drive transistor (210), and is configured to write a compensation signal of the compensation signal end (Vcomp) into the first gate electrode of the dual-gate drive transistor (210) in response to a signal of a first control signal end (S1). The data writing sub-circuit (212) is coupled to a data signal end (Vdata) and the second gate electrode of the dual-gate drive transistor (210). The light-emitting control sub-circuit (213) is coupled to the second electrode of
