Abstract
A driving circuit includes a driving transistor, first to second capacitors and first to third switching transistors. The driving transistor is configured to control a driving current provided to a light emitting element to emit light. The first capacitor includes a first terminal coupled to a gate terminal of the driving transistor. The first switching transistor coupled between a second terminal of the first capacitor and a driving voltage terminal. The second switching transistor includes a first terminal coupled to a gate terminal of the first switching transistor and a second terminal coupled to a first reference voltage terminal. The third switching transistor coupled between a gate terminal of the second switching transistor and a second reference voltage terminal. The second capacitor includes a first terminal coupled to a gate terminal of the third switching transistor and a second configured to receive a sweep signal.
