1. A display device comprising:
pixels disposed in a display area;
an image converter that generates second image data of an (N+1)th frame by using first image data of an N-th frame and first image data of the (N+1)th frame; and
a data driver that supplies a data signal corresponding to the second image data of the (N+1)th frame to the pixels during an (N+1)th frame period, wherein
the image converter detects a logo and a logo area including the logo by using the first image data of the N-th frame,
the image converter calculates a first representative value of data corresponding to a peripheral area of the logo area among the first image data of the N-th frame and a second representative value of data corresponding to a reference area among the first image data of the (N+1)th frame,
the peripheral area is set as an area surrounding the logo area,
the image converter selectively converts data for the logo among the first image data of the (N+1)th frame according to the first representative value and the second representative value to generate the second image data of the (N+1)th frame,
the reference area is set as at least one area of an area of the peripheral area of the logo area that is scanned before the logo area, and
the first representative value is set as a grayscale value of a pixel corresponding to a luminance among grayscale values of the pixels disposed in the peripheral area of the logo area, and the second representative value is set as a grayscale value of a pixel corresponding to a luminance among grayscale values of the pixels disposed in the reference area.
