Abstract: An operating method of an optical fingerprint sensor, an operating method of an electronic device including the optical fingerprint sensor, and a display device including the optical fingerprint sensor are disclosed. The method of operating a fingerprint sensor, wherein the fingerprint sensor senses a fingerprint image based on light reflected from a fingerprint, may include transmitting a first signal indicating a first request to turn on light emission, to a display driving circuit which drives a display panel disposed on the fingerprint sensor, scanning an object on the display panel, based on light irradiated from the display panel, and transmitting, to the display driving circuit, a second signal indicating a second request to turn off the light emission.
