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 display panel including a plurality of pixels configured to receive pixel driving currents; a current sensor configured to measure an entire driving current diverged into the pixel driving currents; and a temperature sensor configured to measure an ambient temperature of the display panel, wherein the display panel includes a degradation compensator configured to generate output grayscale values for the pixels based on the entire driving current, the ambient temperature, and input grayscale values for the pixels.
