A display device includes a display panel including a plurality of pixels configured to display an image, a photo sensor on one surface of the display panel to sense light, and a fingerprint detector configured to control a fake determination image pattern of a fingerprint sensing area of the display panel configured to sense a fingerprint, and to perform fingerprint authentication and fake fingerprint determination, based on a sensing signal supplied from the photo sensor.

Display device and method for driving the same

The display device comprises: a display panel displaying an image, a light blocking layer disposed under the display panel and comprising a plurality of holes, a fingerprint sensing layer disposed under the light blocking layer and comprising a plurality of fingerprint sensors receiving reflected light passing through the plurality of hole and generating a sensing signal, and a sensor driver controlling operations of the plurality of fingerprint sensors. The sensor driver compares fingerprint data generated based on a sensing signal generated from reflected light by a user's fingerprint with prestored reference data to generate a fingerprint image.
