摘要： A display apparatus includes a timing controller and a display panel. The timing controller generates output image data based on input image data and generates a polarity control signal by analyzing the input image data. The display panel displays a plurality of frame images based on the output image data during a plurality of frames and operates based on an inversion driving scheme in which a polarity pattern of the plurality of frame images is changed based on the polarity control signal per N frames, where N is a natural number. The number N is variable based on the polarity control signal.
