Abstract
An image display device includes a plurality of pixels, a pixel detection unit configured to detect first pixels having same R, G, and B gray scale values for a predetermined time among the plurality of pixels, a gray scale value calculation unit configured to calculate average gray scale values of the first pixels and average gray scale values of corresponding R, G and B of second pixels in a predetermined area around the first pixels, a data correction unit configured to correct the R, G and B gray scale values of the first pixels, using the calculated average gray scale values of the first and second pixels, and a data driver configured to correct the image data with the corrected R, G and B gray scale values of the first pixels, and to supply the corrected image data to each pixel of the plurality of pixels.
