1. A display device comprising:
pixels;
an image converter which generates a second image by correcting grayscales of a first logo in a first image for the pixels; and
a data driver which provides data signals corresponding to the second image to the pixels,
wherein the image converter detects the first logo based on value and saturation of the first image, generates first map data corresponding to the first logo, and specifies pixels corresponding to the first logo based on the first map data,
wherein the image converter includes a first logo detector which generates first sub-map data based on the value of the first image, generates second sub-map data based on the saturation of the first image, and generates the first map data by combining the first sub-map data and the second sub-map data.
