Abstract: A display device includes a display panel including a plurality of pixels, an image data corrector configured to generate a corrected image data by adjusting an image data and a data driver providing data signals to the plurality of pixels based on the corrected image data. The image data corrector divides the display panel into a plurality of unit areas, and adjust the image data for a unit area among the plurality of unit areas by using a full image load for the entire display panel, a first image load for the unit area, and a second image load for peripheral unit areas surrounding the unit area among the plurality of unit areas.

Abstract: A display device includes a display panel and a display panel driver. The display panel includes pixels. The display panel driver determines an average image load of input image data, determines an operation mode based on a grayscale value of the input image data and the average image load as a first operation mode or a second operation mode, applies a first scale factor to the input image data in the first operation mode, applies a second scale factor different from the first scale factor to the input image data in the second operation mode, and drives the display panel.

Abstract: A display device determines a target temperature based on an average luminance of each of the panel blocks, calculates a temperature change amount of each of the panel blocks by multiplying a difference between the target temperature and a previous prediction temperature of each of the panel blocks determined before a reference period by a block temperature coefficient of the panel blocks, and calculates a current prediction temperature of each of the panel blocks by adding the temperature change amount of each of the panel blocks to the previous prediction temperature of each of the panel blocks, the panel blocks include a first panel block and second panel blocks adjacent to the first panel block, and the block temperature coefficient of the first panel block is determined based on the target temperature of the first panel block and the target temperature of each of the second panel blocks.
