Abstract
A display apparatus includes a data processor generating gamma data. The data processor sequentially selects each of a plurality of pixels as a reference pixel, calculates difference values between a reference grayscale value provided to the reference pixel and comparison grayscale values provided to comparison pixels adjacent to the reference pixel, compares the difference values to a threshold value, counts up a value of a grayscale grade to which the reference grayscale value belongs among a plurality of grayscale grades according to the compared result, and varies the gamma data based on distribution ratios of values accumulated in the grayscale grades.
