Abstract: A display device may include a pixel and a sensor. The pixel may include an emission element and a pixel driving circuit. The pixel driving circuit may receive a first scan signal and a second scan signal. The sensor may include a light sensing element and a sensor driving circuit. The sensor driving circuit may include a reset transistor, an amplifying transistor, and an output transistor. The reset transistor may receive a reset voltage and the first scan signal and be connected to a first sensing node. The amplifying transistor may receive a first driving voltage and be connected between the first sensing node and a second sensing node. The output transistor may receive the second scan signals and be connected between the second sensing node and a readout line.

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.
