1. A display device comprising:
a display panel including a plurality of sub-pixels arranged in a first pixel arrangement structure; and
a display driver which receives input image data corresponding to a second pixel arrangement structure different from the first pixel arrangement structure,
wherein, when the display device is in a normal driving mode, the display driver generates first output image data for all of the plurality of sub-pixels by performing a first rending operation on the input image data, and drives all of the plurality of sub-pixels based on the first output image data, and
wherein, when the display device is in a low power driving mode, the display driver generates second output image data for a portion of the plurality of sub-pixels by performing a second rending operation different from the first rending operation on the input image data, and drives the portion of the plurality of sub-pixels based on the second output image data,
wherein the display panel includes a plurality of pixel groups,
wherein each of the plurality of pixel groups is defined by first and second red sub-pixels, first through fourth green sub-pixels and first and second blue sub-pixels,
wherein, with respect to each of the plurality of pixel groups, the input image data include first through fourth red sub-pixel data, first through fourth green sub-pixel data and first through fourth blue sub-pixel data, and
wherein one red sub-pixel of the first and second red sub-pixels, two green sub-pixels of the first through fourth green sub-pixels, and one blue sub-pixel of the first and second blue sub-pixels in each of the plurality of pixel groups are driven in the low power driving mode.
