Claim 0:
1. A driving controller comprising:
a logo determiner configured to determine whether or not input image data includes a logo;
a logo grayscale value calculator configured to calculate a logo grayscale value of a logo area corresponding to the logo in response to the input image data including the logo;
a light emitting element life expectancy determiner configured to determine a life expectancy of a light emitting element corresponding to the logo area;
a compensation reference grayscale value generator configured to determine a compensation reference grayscale value according to the life expectancy of the light emitting element corresponding to the logo area; and
a logo luminance compensator configured to compare the logo grayscale value to the compensation reference grayscale value to determine whether or not to compensate a luminance of the logo area,
wherein the logo determiner is configured to determine that the input image data includes 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.
