Abstract

A pixel circuit includes a light-emitting element, a driving circuit, a first light-emitting control circuit, a compensation control circuit and a resetting circuit. The resetting circuit is configured to write an initial voltage into the first electrode of the light-emitting element under the control of a first light-emitting control signal, the first light-emitting control circuit is configured to control the first electrode of the light-emitting element to be electrically connected to the first terminal of the driving circuit under the control of a second light-emitting control signal, and the compensation control circuit is configured to control the control terminal of the driving circuit to be electrically connected to the first terminal of the driving circuit under the control of a first scanning signal.
