    摘要： A pixel circuit, a driving method, a display panel and a display device. The pixel circuit includes: at least two pixel sub-circuits, a data line, a first scan line, a second scan line, a third scan line and a light-emitting control line. The pixel sub-circuit includes: a light-emitting control sub-circuit, a node reset sub-circuit, a drive control sub-circuit, a write sub-circuit and a light emitting device. The light-emitting control sub-circuit is configured to provide a signal provided by the first voltage signal end to a first node; the node reset sub-circuit is configured to form a conductive path between the first node and a second node; the write sub-circuit is configured to write a data signal provided by the data signal end and a threshold voltage to the second node; and the drive control sub-circuit is configured to drive the light emitting device to emit light.
