18. A method of driving a display device, the method comprising:
-
supplying normal data voltages to normal pixels to display an image;
supplying a first sample data voltage obtained from the normal data voltages to a sample pixel to emit light;
supplying a second sample data voltage having a fixed value to the sample pixel to emit light;
determining values of gray voltages based on a luminance of the sample pixel according to the second sample data voltage; and
generating the normal data voltages from the gray voltages. - View Dependent Claims (19)
