Abstract

Embodiments of the present disclosure provide a pixel unit and a driving method thereof, a display panel and a driving method thereof, and a display apparatus. The pixel unit comprises a driving sub-circuit, a first switching sub-circuit, a second switching sub-circuit, and a light-emitting element. The driving sub-circuit has a first terminal electrically coupled to a first power supply terminal, and a second terminal electrically coupled to a first terminal of the light-emitting element. The first switching sub-circuit has an inputting terminal electrically coupled to a data line, an outputting terminal electrically coupled to an inputting terminal of the second switching sub-circuit, and a controlling terminal electrically coupled to a scanning line. The second switching sub-circuit has an outputting terminal electrically coupled to an inputting terminal of the driving sub-circuit.
