Abstract:
An embodiment of the present disclosure provides an actively driven organic light-emitting display apparatus to eliminate a defect in which the current flowing through the lighting device in the actively driven organic light-emitting display apparatus is affected by the instable current caused by the instable threshold voltage of the drive transistor, so that the current flowing through the lighting device is accurate and make the brightness of the whole actively driven organic light-emitting display apparatus be even. The display apparatus comprises a light emitting device, a light emitting device drive unit, a first switch unit, a second switch unit, a current control unit and a resistor which constitute a feedback loop. An input terminal of the current control unit is input a data signal to control that the current of the light emitting device is only associated with the resistor, voltage of the input data signal and the supply voltage.
