Abstract: In a display device including pixels that are coupled to data lines, that are supplied with a data signal during a display period, and that are configured to emit light corresponding to the data signal during a bias period, the display device includes a source capacitor coupled to each of the data lines, and a data driver configured to supply the data signal during the display period, to supply a bias signal during a first period in the bias period, and to not supply the bias signal during a second period.

Abstract: A display device may include a pixel, an emission control driver, and a timing controller. The emission control driver may supply an emission control signal set for controlling emission periods of the pixel. The timing controller may receive a received bit stream that includes a first bit set and a second bit set, may determine a first duty ratio of the emission control signal set using bits of the first bit set without using any bit of the second bit set. The first bit set may include at least two bits. The second bit set may include at least one bit. The emission control signal set may control the pixel to operate according to the first duty ratio for each frame of a first frame group.
