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: A display device includes a set period setting unit for setting, as a set time, a time for which a set period elapses from a time at which a first area included in an input image is detected as a still area, and a gain generator for gradually decreasing an initial level of a gain value down to a saturation level having a lowest value of the gain value from the set time. The set period setting unit differently sets the saturation level of the gain value and a final level of the gain value, corresponding to grayscale values of the first area and a load value of the input image. The load value is an average value of grayscale values of an entirety of an area of the input image.
