Abstract

A display device includes a display panel having a display area including pixels in a emitting area, a layer disposed on the display panel and including photo sensors to generate sensing signals upon activation thereof, a panel driving unit to supply a first signal, during a first mode, to display an image in the display area, and supply a second signal, during a second mode, to increase the luminance of the emitting area, a detecting unit to perform a fingerprint sensing operation to detect a fingerprint, during the second mode, based on sensing signals received from the photo sensors, and a setting unit to change a characteristic of the emitting area in response to the fingerprint sensing operation.
