Abstract: A display device is provided that includes a plurality of pixels, a plurality of optical sensors, an emission line connected to the pixels, and an emission driver connected to the emission line. The emission driver outputs a first emission signal to the emission line having a first frame frequency in a first mode for displaying an image using the pixels and outputs a second emission signal to the emission line having a second frame frequency in a second mode for sensing light using the optical sensors. The second frame frequency is different from the first frame frequency.
