Abstract: A display device includes a display panel configured to display an image. A biometric sensor module is disposed on the display panel. The biometric sensor module is configured to output a first transmission signal having a first frequency to sense fingerprint information in a fingerprint sensing mode. The biometric sensor is also configured to output a second transmission signal having a second frequency that is different from the first frequency to sense skin condition information in a skin measuring mode.
