Driving controller, display device, and method of driving the same

A electronic device comprising:

• a display panel including sub-pixels;
• a data driver which provides data voltages to the sub-pixels;
• a gate driver which provides gate signals to the sub-pixels;
• an emission driver which provides emission signals to the sub-pixels;
• and
• a driving controller which controls the data driver and the gate driver,
• wherein the driving controller determines an on-duty period of an emission signal of the emission signals, based on a number of at least one cycle of a current frame, determines a first compensation value of a bias voltage according to a variation of the on-duty period, determines a second compensation value of the bias voltage, based on a driving frequency of a previous frame, and determines a third compensation value, based on the first compensation value and the second compensation value.
