Abstract
A display device includes 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 determines the emission off ratio as a second off ratio in the second dimming period.
Claims20
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.

A method of driving a display device, the method comprising:
- determining a first dimming period, a second dimming period, and a third dimming period based on a maximum luminance;
- determining an emission off ratio of pixels as a first off ratio increasing discretely as the maximum luminance decreases in the first dimming period;
- determining the emission off ratio as a second off ratio in the second dimming period;
- and
- determining the emission off ratio as a third off ratio in the third dimming period,
- wherein the emission off ratio increases discretely to a plurality of different levels at a plurality of discretely increasing points during the first dimming period while the maximum luminance remains the same between contiguous discretely increasing points of the plurality of discretely increasing points.
