Display device and method of driving the same

A method of driving a display device, the display device comprising a display panel including a plurality of first pixels that form a first region and a plurality of second pixels that form a second region, the method comprising:

• receiving input image data at a controller electrically connected to the display panel and configured to generate modified image data from the input image data;
• first applying a preset first image processing algorithm to process the input image data corresponding to the first pixels via the controller so as to generate first modified mage data;
• and
• second applying a preset second image processing algorithm to process the input image data corresponding to the second pixels via the controller so as to generate second modified image data,
• wherein the second region does not overlap the first region and fully surrounds the first region,
• wherein the first region is formed in a center portion of the display panel, and the second region has the shape of a substantially circular ring, a substantially oval ring, a substantially square ring, or a polygonal ring,
• wherein the pixels include a plurality of boundary pixels,
• wherein the boundary pixels form a boundary region,
• wherein the boundary region surrounds the first region,
• wherein the second region surrounds the boundary region,
• wherein the boundary region comprises a first boundary region including a plurality of first boundary pixels and a second boundary region including a plurality of second boundary pixels,
• wherein the method further comprises i) third applying the first image processing algorithm to the input image data corresponding to first boundary pixels and ii) fourth applying the second image processing algorithm to image data corresponding to pixels formed in the second boundary region, from among the input image data so as to generate modified boundary image data,
• wherein the third and fourth applying are performed by the controller,
• wherein the first and second boundary regions are formed in the boundary region in a mosaic form,
• wherein the first group of pixels formed in the first region are divided into a first pixel set arranged in an n×n form, wherein the second group of pixels formed in the second region are divided into a second pixel set arranged in an m×m form, and wherein the first and second boundary regions having the mosaic form comprise the first pixel set and the second pixel set alternately arranged in vertical and horizontal directions.
