摘要：A pixel circuit and a driving method thereof, and a display panel are provided. The pixel circuit (10) includes a driving circuit (100), a data writing circuit (200), a storage circuit (300), an electrical compensation circuit (500), and an optical compensation circuit (600). The driving circuit (100) controls a driving current that drives a light emitting element (400) to emit light. The data writing circuit (200) writes a data signal to a control terminal (130) of the driving circuit (100) in response to a scanning signal. A first terminal and a second terminal of the storage circuit (300) are respectively connected to the control terminal (130) and a second terminal (120) of the driving circuit (100), and the storage circuit (300) is used for storing the data signal. The electrical compensation circuit (500) is connected to the second terminal (120) of the driving circuit (100), and electrically connects the second terminal (120) of the driving circuit (100) to a first detecting terminal (SI) in response to an electrical detection enable signal. The optical compensation circuit (600) applies an electrical signal, which is generated according to the light emitted from the light emitting element (400), to the second detecting terminal (S2) in response to an optical detection enable signal. The pixel circuit can compensate for brightness uniformity.
