Abstract: A pixel circuit includes a light-emitting element, a data write-in sub-circuit, a driving sub-circuit, a storage sub-circuit, a light-emission control sub-circuit, and a step-down sub-circuit. The step-down sub-circuit is configured to, at a charging compensation stage, step down a data voltage to acquire a first step-down voltage, and output the first step-down voltage via a control node. The storage sub-circuit is configured to, at the charging compensation stage, charge or discharge the control node to enable a potential at the control node to be the first step-down voltage, and at a light-emitting stage, maintain the potential at the control node as the first step-down voltage. The driving sub-circuit is configured to, at the light-emitting stage, enable a first end of the driving sub-circuit to be electrically connected to a first electrode of the light-emitting element under the control of the control node, to drive the light-emitting element to emit light.
