Abstract
A pixel circuit, a parameter detection method, a display panel and a display device are provided. The pixel circuit includes a data writing-in circuit, a driving circuit, a reset control circuit, a detection control circuit, and a light emitting element. The detection control circuit is configured to control the connection or disconnection between the first electrode of the light emitting element and the sensing line under the control of a detection control signal provided by the detection control line. The reset control circuit is configured to control the connection or disconnection between the first electrode of the light emitting element and the second electrode of the light emitting element under the control of a reset control signal provided by the reset control line.
