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.

Abstract: The present disclosure provides a pixel structure, a display panel and a fabrication method thereof, and a display device. The pixel structure includes a substrate and an inorganic photoluminescent layer formed on the substrate. The pixel structure incudes an excitation layer disposed on a side of the inorganic photoluminescent layer away from the substrate and configured to excite the inorganic photoluminescent layer to emit light. The pixel structure includes an organic light-emitting layer in the same layer as the excitation layer. A space is disposed between the organic light-emitting layer and the excitation layer. An orthographic projection of the excitation layer on the substrate overlaps at least partially an orthographic projection of the inorganic photoluminescent layer on the substrate.
