Abstract: A gamma correction apparatus for a display device, includes: a measurer configured to measure an optical characteristic of a display panel; and a gamma data generator configured to generate measurement gamma data for at least one measurement gray level pre-determined from among a plurality of gray levels, based on the optical characteristic received from the measurer, generate prediction gamma data for at least one prediction gray level other than the at least one measurement gray level from among the plurality of gray levels by using an equation defining a relationship between a gray level and an optical characteristic, and generate gray level-wise gamma data, based on the measurement gamma data and the prediction gamma data.

Abstract: In a method of operating a display device, it is determined whether an image represented by input image data is a single color image, it is determined whether the image represented by the input image data is a low gray image, compensated image data are generated by adding sub-pixel data corresponding to a color different from a color of the single color image to the input image data when the image represented by the input image data is the single color image and the low gray image, and an image is displayed based on the compensated image data.
