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.

Abstract: A display apparatus includes a gamma controller configured to determine whether the target pixel unit is driven in both time division method and space division method based on a plurality of comparison values and a reference condition, and an output controller configured to generate normal gamma-data of the target pixel unit using a normal gamma curve if the plurality of comparison values satisfy the reference condition and to generate high gamma-data and low gamma-data of the target pixel unit using a high gamma curve and a low gamma curve in both time division method and space division method if the plurality of comparison values do not satisfy the reference condition.
