Claim 15:
16. A method of driving a display panel, the method comprising:
determining whether or not input image data includes a logo;
calculating a logo grayscale value of a logo area corresponding to the logo in response to the input image data including the logo;
determining a life expectancy of a light emitting element corresponding to the logo area;
determining a compensation reference grayscale value according to the life expectancy of the light emitting element corresponding to the logo area;
comparing the logo grayscale value to the compensation reference grayscale value to compensate a luminance of the logo area;
generating a data signal based on the input image data having the compensated luminance of the logo area;
converting the data signal to a data voltage; and
outputting the data voltage to the display panel,
wherein the input image data is determined to include the logo in response to a fixed image being maintained over a reference time period and a size of the fixed image being included in a reference size range.
