Abstract: A display device includes a shift controller which generates an output image by shifting an input image within a shift range; and pixels which displays the output image. The shift controller sets the shift range to a first range when the input image is a moving image, and sets the shift range to a second range smaller than the first range when the input image is a still image.

Abstract: A display device and a method of driving the same are provided. The method of driving the display includes a display area to display an image. The method includes performing a first first pixel shift driving by shifting an image by a first range in the display area without loss of image information due to enlargement or reduction of the image, checking whether a change of a block grayscale value is greater than or equal to a threshold in an interest area in the display area, and performing second pixel shift driving by shifting an image having the loss of image information.

Abstract: In order to display an image in a display device, in which a plurality of sub pixels within a unit pixel receives driving power from one driving power line, a driving voltage stability weak pattern is detected by analyzing image data. When the input image is determined as the driving voltage stability weak pattern, a white balance correction gain of each sub pixel is decreased while a ratio among the white balance correction gains of the sub pixels is maintained. Target luminance for displaying the input image is changed. A voltage level of the driving power is change in accordance with the changed target luminance.
