Abstract: A pixel circuit, a pixel driving method and a display device. The pixel circuit includes a light-emitting element, a driving circuit, a first energy storage circuit, a second energy storage circuit, a data writing circuit, and a compensation control circuit. The data writing circuit controls writing of a data voltage on a data line into a data writing node under control of a scanning signal. The compensation control circuit controls whether a second node is connected with or disconnected from a compensation node under control of a first reset signal. The compensation node is electrically connected to a third node, and/or, the compensation node is electrically connected to a second terminal of the driving circuit. The present disclosure can achieve high-frequency driving under the premise of sufficient compensating for the threshold voltage of the driving transistor included in the driving circuit.
