Abstract: A display device is provided. The display device includes a display panel including a pixels; a fingerprint recognition sensor including an image sensor disposed under a first surface of the display panel; and a processor to control the display panel and the fingerprint recognition sensor. A portion of display pixels are configured to emit light in a fingerprint recognition mode. The image sensor includes pixels, at least a portion of the pixels are phase detection pixels. The image sensor generates a fingerprint image signal and a fingerprint phase signal based on reflected light received while the portion of display pixels emit light. The main processor is further configured to perform an anti-spoofing operation or a fingerprint authentication operation based on the fingerprint image signal and the fingerprint phase signal.
