Display device

A display device, comprising:

• a display panel including a pixel and an emission line connected to the pixel;
• an emission driver which provides an emission signal to the emission line,
• wherein the emission signal defines discontinuous emission periods and non-emission periods during a frame period among a plurality of frame periods;
• and
• a controller which determines an emission cycle corresponding to a number of the discontinuous emission periods during the frame period and an emission-off ratio which is a ratio of a sum of the non-emission periods to the frame period,
• wherein the plurality of frame periods includes an n−1th frame period, an n+1th frame period, and an nth frame period between the n−1th frame period and the n+1th frame period,
• wherein the emission cycle of the n−1th frame period is different from the emission cycle of the n+1th frame period, the emission-off ratio of the n−1th frame period is equal to the emission-off ratio of the n+1th frame period, and the nth frame period includes first to mth sub-frame periods having different emission-off ratios,
• wherein each of m and n is a positive integer greater than 1.
