Abstract: A display device is disclosed that includes pixels, a memory, and a degradation compensator. The pixels include light emitting elements. The memory is operable to store degradation information including degradation degrees of the light emitting elements. The degradation compensator is operable to receive the degradation information and generate output grayscales by changing each of input grayscales of the pixels in proportion to each of the degradation degrees. The degradation compensator includes a degradation information changer for changing the degradation information by decreasing a degradation degree having a variation greater than a threshold value among variations of the degradation degrees.

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 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.
