Abstract
A display apparatus includes a display panel, a timing controller, data and gate driving parts. The display panel includes first and second substrates, and a liquid crystal layer disposed between the first and second substrates, and displays an image. The timing controller includes a data compensating unit that outputs compensated grayscale data in an n-th pixel row, based upon a coupling capacitance generated according to a grayscale data variation between an (n−1)-th pixel row and the n-th pixel row, n′ being a natural number. The data driving part converts the compensated grayscale data to an analog data voltage, and outputs the analog data voltage to data lines.
