1. A display device comprising:
a display panel comprising:
scan lines;
sensing lines;
pixels electrically connected to each of the scan lines; and
photo sensors electrically connected to each of the scan lines and the sensing lines;
a scan driver which outputs scan signals to the scan lines according to a scan control signal;
a timing controller which outputs the scan control signal to the scan driver; and
a readout circuit which receives light sensing signals of the photo sensors from the sensing lines, wherein
the timing controller sets a frame frequency of the scan control signal to a first frame frequency in a first mode in which the display panel displays an image, and
the timing controller sets the frame frequency of the scan control signal to a second frame frequency different from the first frame frequency in a second mode in which the photo sensors sense a fingerprint, wherein
the first frame frequency and the second frame frequency are non-zero.
