Abstract: Provided is a complex biometric sensor. The complex biometric sensor includes a substrate including a light emitting region, a first light receiving region, and a second light receiving region, a light emitting part disposed adjacent to the substrate in the light emitting region, a color conversion layer disposed on the substrate in the light emitting region and vertically overlapping the light emitting part; a first light receiving layer disposed on the substrate in the first light receiving region, and a second light receiving layer disposed on the substrate in the second light receiving region. The light emitting part generates light of a first wavelength. The color conversion layer receives light of the first wavelength and emits the light of the first wavelength and light of the second wavelength. The first light receiving layer detects the light of the first wavelength. The second light receiving layer detects the light of the second wavelength.

Abstract: Provided is a fingerprint sensor. The fingerprint sensor according to an embodiment of the inventive concept includes a plurality of transmission lines, a plurality of receive lines, and a sensor array including sensor units connected to the plurality of transmission lines. Each of the sensor units includes a switch transistor having a gate terminal and one terminal, which are commonly connected to a corresponding transmission line of the plurality of transmission lines and a sensor transistor connected between the other end of the switch transistor and a corresponding receive line of the plurality of receive lines. The sensor transistor performs a current suppression on in response to a voltage of a virtual gate that is touched by a fingerprint.
