Abstract
A driving circuit for driving a light emitting unit is provided. The driving circuit includes a driving transistor, a switch transistor, an emitting transistor, a first capacitor and a first compensation transistor. The switch transistor is coupled to the driving transistor. The emitting transistor is coupled between the light emitting unit and the driving transistor. The first capacitor is coupled to the driving transistor. The first compensation transistor is coupled to the first capacitor. A first end of the first compensation transistor and a first end of the emitting transistor receive same signal.
