Abstract: A display device includes a display panel divided into panel blocks including pixels, and a display panel driver which drives the display panel, sets a time point to which a set time elapses from a time point when input image data is determined to be a still image as an operation time point, decreases a luminance gain from the operation time point, determines the set time based on accumulated deterioration amounts of the panel blocks, and applies the luminance gain to the input image data.

Abstract: A display device includes a display panel and a display image shift controller. The display panel includes a display area in which a display image is displayed and a shift area located within the display area. The display image shift controller generates a route shift signal, where a reference point of the display image is shifted in the shift area based on the route shift signal. The route shift signal includes first and second routes corresponding to a path through which the reference point of the display image is shifted. The first route includes a first sub-route and a second sub-route. The second route includes a third sub-route and a fourth sub-route. The first, second, third, and fourth sub-routes are different from each other.

Abstract: A display device includes a display panel which includes a compensation area, an image processing device, a timing controller which includes an average luminance decrease rate calculator which calculates an average luminance decrease rate, a luminance decrease rate calculator which calculates a luminance decrease rate for the compensation area, and a data compensator which generates output image data by applying the luminance decrease rate for the compensation area to the input image data, and a data driver which provides data voltages generated based on the output image data to the display panel.
