Abstract
A display device includes a display panel including a plurality of pixels, a gray group data generator configured to receive current line data for pixels in a current row, and to generate current row gray group data based on the current line data, a horizontal crosstalk determiner configured to determine whether horizontal crosstalk occurs in the current row, a horizontal crosstalk compensator configured to compare the current row gray group data with adjacent row gray group data when the horizontal crosstalk is determined to occur in the current row, and to selectively adjust a plurality of gamma reference voltages according to a result of the comparison between the current row gray group data and the adjacent row gray group data, and a data driver configured to generate and provide data voltages corresponding to the current line data based on the selectively adjusted plurality of gamma reference voltages.
