1. A driving circuit, comprising:
a driving transistor, electrically coupled between a first driving voltage terminal and a second driving voltage terminal, and the driving transistor is configured to control a driving current provided to a light emitting element;
a first capacitor, with a first terminal electrically coupled to a gate terminal of the driving transistor;
a first switching transistor, with a first terminal electrically coupled to a first terminal of the driving transistor, with a second terminal electrically coupled to a second terminal of the first capacitor;
a second switching transistor, with a first terminal electrically coupled to a gate terminal of the first switching transistor, with a second terminal electrically coupled a first reference voltage terminal;
a third switching transistor, electrically coupled between a gate terminal of the second switching transistor and a second reference voltage terminal; and
a second capacitor, with a first terminal electrically coupled to a gate terminal of the third switching transistor, with a second terminal configured to receive a sweep signal.
