Abstract

A luminance compensator in a display device includes a temperature sensor that detects a temperature of a display panel, a temperature estimator that calculates an estimated temperature of each of a plurality of pixel blocks based on an average luminance of each pixel block and the temperature of the display panel, a first weight calculator that detects a displacement of the display panel and calculates a first temperature compensation weight for first compensation pixel blocks of the pixel blocks, the first compensation pixel blocks being adjacent to an upper side of an image pattern area displayed on a portion of the display panel, and a temperature compensator that calculates temperature compensation data by applying the first temperature compensation weight to the estimated temperature to compensate the average luminance, and outputs the temperature compensation data.
