Abstract: A display device includes a display unit including a plurality of pixels, a data converter to receive grayscale values respectively corresponding to the plurality of pixels, generate first compensated grayscale values by remapping the grayscale values of a first grayscale range to the first compensated grayscale value of a second grayscale range, and generate second compensated grayscale values by compensating for the first compensated grayscale values based on first compensated grayscale values of adjacent pixels, and a data driver to generate data signals based on the second compensated grayscale values and provide the data signals to the plurality of pixels of display unit, wherein adjacent pixels of a target pixel correspond to pixels adjacent to the target pixel, and wherein at least one of the adjacent pixels emits light having a color different from that of the target pixel.

Abstract: A display device includes: a display unit including pixels connected to data lines and scan lines, the display unit being partitioned into a plurality of blocks; at least one driver overlapping with the display unit in a plan view, where the at least one driver is configured to drive the display unit; a temperature sensor for generating an ambient temperature value; and a timing controller for generating a panel temperature value corresponding to an actual temperature of the display unit by using the ambient temperature value, and generating pixel temperature values corresponding to temperatures of the pixels, respectively, by using the panel temperature value. The timing controller is supplied with input data, and generates output data by reflecting the pixel temperature value on the input data.
