13. A method of driving an electronic device, the method comprising:
receiving input data by a signal control circuit that controls a driving frequency of a display panel;
dividing data of one frame among the input data into a plurality of regions based on a gray scale and calculating a distribution of the data of the one frame based on the plurality of regions;
calculating a number of major grayscales having data of a specific number or more among the input data;
generating a signal calculated based on an optical waveform of the display panel; and
calculating the driving frequency based on the distribution of the data of the one frame, the number of the major grayscales, and the signal.
