Abstract: A display apparatus includes a timing controller, a data driver and a display panel. The timing controller generates a mode selection signal and output image data in response to input image data. The data driver generates first through N-th data voltages in response to the mode selection signal and the output image data and applies the first through N-th data voltages to first through N-th data lines. The display panel is connected to the first through N-th data lines. During the first operation mode, each of a polarity pattern of first through M-th data voltages and a polarity pattern of (M+1)-th through N-th data voltages repeats a first polarity pattern. During the second operation mode, the polarity pattern of the first through M-th data voltages repeats the first polarity pattern, and the polarity pattern of the (M+1)-th through N-th data voltages repeats a second polarity pattern.
