Abstract: A display device capable of substantially preventing a bruising phenomenon and a driving method thereof are provided. The display device includes a display panel which displays an image and a signal controller which controls signals for driving the display panel. The signal controller includes a first accurate color capture (“ACC”) unit which performs ACC correction on input image data to generate first correction image data; a second ACC unit which performs the ACC correction on the input image data to generate second correction image data; and an ACC selection unit which selectively applies the input image data to the first ACC unit or the second ACC unit. A maximum gray of the second correction image data is lower than a maximum gray of the first correction image data.

Abstract: A display device includes a data driver which outputs a data voltage of a positive polarity or a negative polarity to a data line based on the polarity control signal by a horizontal period, and a number of a positive horizontal period, in which the data voltage of the positive polarity is outputted to the data line, in a frame period is different from a number of a negative horizontal period, in which the data voltage of the negative polarity is outputted to the data line, in the frame period when the frame image data satisfy a condition of an afterimage pattern.
