Zusammenfassung: | A light-emitting control circuit comprises a first transistor, a capacitor, a control unit, a first discharge unit, a second discharge unit and a voltage supply unit. The first transistor outputs a light-emitting control voltage according to a control voltage. The control unit outputs the control voltage according to a light-emitting clock pulse signal. The first discharge unit comprises a first discharge transistor and a second discharge transistor which are connected in series. The first discharge unit and the second discharge unit operate according to a discharge control signal and the light-emitting clock pulse signal so as to discharge the control unit and the first transistor respectively when being conducted and to stop discharging when being closed. The voltage supply unit suppliesa discharge suppression voltage to suppress discharge of the first discharge unit when the first discharge unit and the second discharge unit stop discharging by the light-emitting clock pulse signal.
