Abstract: A method of displaying an image in a display device may include determining the degree of deterioration of pixels included in a display unit based on image data of a current frame image, determining a shift route of the current frame image so as to correspond to the determined degree of deterioration. The first image data is corrected to second image data so that the current frame image is shifted along the shift route.

Abstract: A display device including a controller and a display panel. The controller receives original image data and output a display image signal. The display panel receives the display image signal and displays a display image corresponding to the display image signal. The controller includes an image shift controller and a memory. The image shift controller generates shifted image data by modulating the original image data to shift the display image sequentially along a preset shift path on the display panel. The memory stores a shift path value indicating a distance by which the display image has been shifted on the preset shift path. The image shift controller generates the display image signal by processing the shifted image data. When the display device is powered on, the image shift controller generates shifted image data corresponding to a shift path value stored in the memory.

Abstract: A method of displaying an image by using a display device. The method includes: grouping pixels included in a display unit into pixel blocks, generating a first accumulated stress map representing a degree of a deteriorated performance of the pixels included in the pixel blocks based on first image data of a current frame image, and determining a shiftable range of the current frame image by analyzing the first accumulated stress map. The first image data is corrected to second image data in which the current frame image is shifted within the shiftable range.

Abstract: A display device includes an afterimage compensator generating output grayscales by applying at least one of first and second weights to input grayscales when the input grayscales correspond to a still image, and pixels displaying an image based on the output grayscales. The afterimage compensator applies the first weight having an initial value greater than 1 to the input grayscales of a first group, and converges the first weight to 1, and applies the second weight having initial values less than 1 to the input grayscales of a second group, and converges the second weights to 1.
