Abstract: A pixel circuit includes a light-emitting element, a driving circuit, a first light-emission control circuit, a first initialization circuit, an energy storage circuit, a compensation control circuit and a data written-in circuit. A first terminal of the energy storage circuit is electrically connected to a control terminal of the driving circuit, and a second terminal of the energy storage circuit is electrically connected to a first electrode of the light-emitting element. The data written-in circuit writes a data voltage into a first terminal of the driving circuit under control of a written-in control signal. The compensation control circuit controls the control terminal of the driving circuit to be electrically connected to a second terminal of the driving circuit under control of a compensation control signal.
