Claim 12:
13. A display device comprising:
a display panel comprising:
a pixel; and
a photo sensor;

first scan lines which provide a first scan signal to the pixel and the photo sensor;
second scan lines which provide a second scan signal to the pixel;
a scan driver which outputs the first scan signal to the first scan lines and outputs the second scan signal to the second scan lines;
a timing controller which controls the scan driver; and
a readout circuit which receives a light sensing signal from the photo sensor through a sensing line, wherein
a pulse interval between the first scan signal and the second scan signal in a first mode in which the display panel displays an image has a first horizontal period, and
a pulse interval between the first scan signal and the second scan signal in a second mode in which the photo sensor senses a fingerprint has a second horizontal period, the second horizontal period being different from the first horizontal period.
