1. A display device comprising:
a display panel including pixels; and
a timing controller which determines a first dimming period and a second dimming period based on a maximum luminance, determines an emission off ratio of the pixels as a first off ratio increasing discretely as the maximum luminance decreases in the first dimming period, and to determine the emission off ratio as a second off ratio in the second dimming period,
wherein the emission off ratio increases discretely to a plurality of different levels at a plurality of discretely increasing points while the maximum luminance remains the same between contiguous discretely increasing points of the plurality of discretely increasing points during the first dimming period.
