1. A display device comprising:
a display panel which includes a plurality of light emitting pixels connected to emission control lines and scan lines, and a plurality of photosensitive pixels connected to the scan lines, wherein the plurality of photosensitive pixels is operated in an initialization period, a light exposure period and a sensing period;
an emission driver which supplies emission control signals to the emission control lines, based on an emission start signal;
a scan driver which supplies scan signals to the scan lines, based on a scan start signal; and
a timing controller which generates the emission start signal and the scan start signal,
wherein 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.
