Abstract
A pixel circuit and a driving method thereof, and a display panel are provided. The pixel circuit includes a driving circuit, a data writing circuit, a storage circuit, an electrical compensation circuit, an optical compensation circuit. The driving circuit controls a driving current that drives a light emitting element to emit light. The data writing circuit writes a data signal to a control terminal of the driving circuit in response to a scanning signal. The storage circuit is used for storing the data signal. The electrical compensation circuit electrically connects the second terminal of the driving circuit to a first detecting terminal in response to an electrical detection enable signal. The optical compensation circuit applies an electrical signal generated according to the light emitted from the light emitting element to the second detecting terminal in response to an optical detection enable signal.
