1. A display device, comprising:
a display panel comprising a plurality of pixels, each of the plurality of pixels including a light emitting element that emits light; and
a controlling circuit configured to output image data to the display panel based on a first frame of data and a second frame of data that is arranged after the first frame of data, wherein a subject in the image data moves across the first frame of data and the second frame of data
wherein the controlling circuit comprises:
a frame generating circuit configured to generate for the first frame of data a luminance emphasis frame having a luminance value of the subject that is increased relative to a luminance value of the subject in the first frame of data and a black insertion frame where a black color is inserted into the subject to replace a color of the subject in the first frame of data; and
a frame outputting circuit configured to sequentially output the luminance emphasis frame and the black insertion frame to the display panel instead of the first frame of data,
wherein the display panel displays the luminance emphasis frame and the black insertion frame after the luminance emphasis frame.
