Foldable electronic device for detecting fingerprints through at least a part of display

An electronic device comprising:

• a hinge;
• a first housing connected to the hinge, the first housing comprising a first surface and a second surface directed in an opposite direction of the first surface;
• a second housing connected to the hinge, the second housing comprising a third surface and a fourth surface directed in an opposite direction of the third surface, the second housing being configured such that the first surface faces the third surface in a folded state and the first surface and the third surface are directed in a same direction in an unfolded state;
• a first display disposed over the first surface and the third surface, wherein the first display includes a first fingerprint contact portion formed at a portion of the first display corresponding to the third surface such that a first light is transmitted through the first fingerprint contact portion into the second housing;
• a second display exposed to an outside through at least a portion of the fourth surface, wherein the second display includes a second fingerprint contact portion formed at a portion of the second display such that a second light is transmitted through the second fingerprint contact portion into the second housing;
• a first reflective member configured to reflect the first light;
• a second reflective member configured to reflect the second light and not overlap with the first reflective member in a direction perpendicular to the first display;
• and
• an image sensor configured to detect the first light and the second light,
• wherein the first reflective member is disposed to reflect the first light such that the reflected first light forms a first path from the first reflective member toward the image sensor, and
• wherein the second reflective member is disposed to reflect the second light such that the reflected second light forms a second path from the second reflective member toward the image sensor.
