Abstract
A pixel driving circuit is provided. The pixel driving circuit includes a first circuit, a second circuit, and one or more third circuits. The first circuit is configured to compensate for a variation in a threshold voltage in a driving transistor in the one or more third circuits. The first circuit is coupled to a first control signal line, a second control signal line, a first light emitting control signal line, and a second light emitting control signal line. The second circuit is coupled to the first light emitting control signal line and the second light emitting control signal line. The first light emitting control signal line and the second light emitting control signal line are configured to transmit light emitting control signals having reversed phases.
