Abstract: A display device includes a signal controller and a data driver. The signal controller processes an input image signal to generate an output image signal. The signal controller processes the input image signal using a correction unit. The correction unit corrects the input image signal to a first gray scale value greater than 0 gray scale value when the gray scale value of the input image signal is 0. The output image signal is based on the corrected input image signal. The data driver converts the output image signal into a data voltage to be applied to a display panel.
