Abstract
A pixel circuit, a display panel, a display device and a driving method are disclosed. The pixel circuit includes: a light-emitting circuit including a plurality of light-emitting sub-circuits (111); and a compensation driving circuit including an output terminal and a driving transistor. The plurality of light-emitting sub-circuits are all electrically connected to the output terminal; and the compensation driving circuit is configured to receive a light-emitting data signal, compensate for a threshold voltage of the driving transistor, and drive any one of the plurality of light-emitting sub-circuits to emit light according to an output signal output by the output terminal.
