Zusammenfassung:A pixel circuit includes a first transistor, a second transistor and a driving transistor. The first transistor is configured to selectively be turned on according to a light emitting control signal, wherein the first end of the first transistor is coupled to a first node, and the second end of the first transistor is coupled to a light emitting element. The second transistor is coupled to the first transistor and is configured to selectively be turned on according to a light emitting switch signal. The first end of the driving transistor receives a system low voltage, and the second end of the driving transistor is coupled to the first node. The light emitting control signal has a first pulse frequency, the light emitting switch signal has a second pulse frequency, and the first pulse frequency is higher than the second pulse frequency. The duty ratio of the light emitting control signal is lower than 50%.
