1. A display apparatus comprising:
a display panel comprising a first display area having a first pixel density and a second display area having a second pixel density higher than the first pixel density; and
a display panel driver driving the display panel in a first mode when an image complexity of input image data corresponding to a determination area which includes the first display area and a portion of the second display area disposed adjacent to the first display area is greater than a threshold value and driving the display panel in a second mode different from the first mode when the image complexity of the input image data corresponding to the determination area is less than or equal to the threshold value,
wherein the second display area includes a first adjacent display area disposed adjacent to the first display area and surrounding the first display area, a second adjacent display area disposed adjacent to the first adjacent display area and surrounding the first adjacent display area and a third adjacent display area disposed adjacent to the second adjacent display area and surrounding the second adjacent display area, and
wherein a luminance of the first display area is less than a luminance of the first adjacent display area for the same grayscale value, the luminance of the first adjacent display area is less than a luminance of the second adjacent display area for the same grayscale value, the luminance of the second adjacent display area is less than a luminance of the third adjacent display area for the same grayscale value and the luminance of the third adjacent display area is less than a luminance of an area of the second display area except for the first adjacent display area, the second adjacent display area and the third adjacent display area for the same grayscale value in the first mode.
