Abstract: An electronic device is provided. The electronic device may include: a housing including a first face facing a first direction and a second face facing a second direction opposite the first direction, and further including a transparent window comprising at least a portion of the first face; a display device disposed between the first face and the second face of the housing and configured to display information to an outside through the transparent window; an illumination unit comprising light emitting circuitry disposed inside the first face of the housing and configured to emit light toward the transparent window; a reflective unit comprising a reflective surface and disposed between the illumination unit and the transparent window, and including a plurality of reflective structures configured to reflect light emitted from the illumination unit toward the transparent window; and a biometric sensor disposed to face at least a portion of the transparent window and configured to sense light reflected on the transparent window. The electronic device including a fingerprint sensor is capable of ensuring a superior performance using a light source in sensing fingerprint information of a user using a fingerprint sensor located in a display active region. Further, the electronic device is capable of effectively ensuring an amount of incident light transmitted to the biometric sensor using the reflective unit and the transparent window, which substantially completely reflects the light emitted from the light source.

Abstract: An electronic device is provided. The electronic device includes an optical sensor, the optical sensor comprising a lighting device configured to emit light, a sensor layer including an array of sensors configured to detect first image information corresponding to an object from light reflected by the object, and a filter layer including openings configured to transmit the light reflected by the object, the filter layer disposed on the sensor layer, wherein the first image information is different from an image of the object identified with naked eyes. The electronic device may be diversified according to embodiments.
