Abstract: A display apparatus includes a display panel which displays an image, a compensation area determiner which divides a display area of the display panel into a compensation area and a normal area, a compensation coefficient determiner which determines a compensation coefficient corresponding to input data of the compensation area, a compensation look up table which stores a noise compensation data which compensates a luminance difference of the compensation area by an interference noise of a light-source driving signal, and a correction data calculator which calculates a correction data corresponding to the input data of the compensation area using the compensation coefficient and the noise compensation data.
