Abstract: A display device includes a signal receiver, a signal generator, and a signal corrector. The signal receiver receives an image signal. The signal generator generates a data signal for each of a first color pixel and a second color pixel based on the image signal. The signal corrector generates corrected data for the first color pixel based on the data signal for the second color pixel in a single driving mode. The first color pixel and the second color pixel emit light of different grayscale values of a same color. The first color pixel is driven and the second color pixel is not driven in the single driving mode.
