Abstract: A display device includes: a display panel having a first region and a second region defined in the display panel, in which the second region is adjacent to the first region in a first direction. The display panel includes: a first pixel disposed in the first region, a second pixel disposed in the second region, a first bias voltage line electrically connected to the first pixel to transmit a first bias voltage, and a second bias voltage line electrically connected to the second pixel to transmit a second bias voltage. A time point, at which a level of the first bias voltage is changed, differs from a time point at which a level of the second bias voltage is changed, when the display panel operates at a first frame frequency.

Abstract: In a method of operating a display device, it is determined whether an image represented by input image data is a single color image, it is determined whether the image represented by the input image data is a low gray image, compensated image data are generated by adding sub-pixel data corresponding to a color different from a color of the single color image to the input image data when the image represented by the input image data is the single color image and the low gray image, and an image is displayed based on the compensated image data.
