A driving controller includes: 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.
