1. A display device comprising:
a driving frequency calculator configured to:
divide output image data into a central image, an intermediate image, and a peripheral image respectively corresponding to a central visual field region, an intermediate visual field region, and a peripheral visual field region;
calculate spatial frequencies of the central image, the intermediate image, and the peripheral image;
calculate critical flicker frequencies of the central visual field region, the intermediate visual field region, and the peripheral visual field region based on the spatial frequencies and based on viewing angles of the central visual field region, the intermediate visual field region, and the peripheral visual field region; and
determine driving frequencies of the central visual field region, the intermediate visual field region, and the peripheral visual field region based on the critical flicker frequencies; and
a display panel configured to display an image based on the output image data and based on the driving frequencies.
