Abstract
A pixel circuit, a driving method, and a display device. The pixel circuit includes a light-emitting element, a data writing circuit, a first control circuit, a driving circuit, a first power storage circuit, and a second power storage circuit. The first control circuit is configured to write a first initial voltage provided by a first initial voltage terminal into a first electrode of the light-emitting element under control of a first control signal provided by a first control terminal in a non-light-emitting phase. The driving circuit drives the light-emitting element to emit light under the control of a potential of a control terminal of the driving circuit. The present disclosure enhances the contrast in the non-light-emitting phase.
