Abstract: A display device includes: a display panel; an emission driver; a scan driver; and a timing controller. The display panel includes light emitting pixels and photosensitive pixels, where the photosensitive pixels are operated in an initialization period, a light exposure period and a sensing period. The emission driver supplies emission control signals to emission control lines connected to the light emitting pixels, based on an emission start signal. The scan driver supplies scan signals to scan lines connected to the light emitting pixels and the photosensitive pixels, based on a scan start signal. The timing controller generates the emission start signal having a single pulse of a gate-off level and the scan start signal having a single pulse of a gate-on level in a last frame period among frame periods corresponding to the light exposure period and in each of frame periods corresponding to the sensing period.
