Abstract:
A method of driving an active display device. The method including recovering a threshold voltage of a switching transistor connected to a pixel. The recovering including applying a negative bias voltage to the switching transistor prior to charging each pixel during a charging period. The negative bias voltage is applied to a drain of the switching transistor.
