Abstract: A method of driving a display panel includes adjusting a level of a data sustaining voltage or an on bias voltage during an on bias compensating period, applying the on bias voltage to pixels through data lines during an on bias period, which is subsequent to the on bias compensating period, to adjust a voltage level of control electrodes of driving transistors of the pixels, initiating a voltage of anode electrodes of organic light emitting elements of the pixels during an initiating period, applying data voltages to the pixels through the data lines during a scanning period, and turning on the organic light emitting elements of the pixels during an emission period.
