Abstract
A display device includes a driving frequency calculator configured to divide output image data into central, intermediate, and peripheral images respectively corresponding to central, intermediate, and peripheral visual field regions, 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.
