Abstract
A pixel circuit, a display substrate, a display device and a driving method are provided. The pixel circuit includes a data writing sub-circuit and a driving sub-circuit, and the data writing sub-circuit is connected to a scan signal terminal, a control signal terminal, a data signal terminal and a drive sub circuit. The data writing sub-circuit is used to output a data signal from the data signal terminal to the control node in response to a control signal provided by the control signal terminal and a scan signal provided by the scan signal terminal. The driving sub-circuit is connected to the control node, a power signal terminal and a light-emitting element, respectively, and is used to drive the light-emitting element to emit light in response to a potential of the control node and a power signal provided by the power signal terminal.
