Electronic device including light blocking member with micro-hole

An electronic device comprising:

• a housing comprising:
• a first surface facing in a first direction, a second surface facing in a second direction opposite to the first direction, and
• a transparent member forming at least part of the first surface;
• a display device disposed between the first surface and the second surface of the housing, and configured to display information to the outside through the transparent member;
• a light blocking member disposed to face one surface of the display device, and configured to block light directed in the second direction from the display device;
• and
• a biometric sensor module disposed between the first surface and the second surface of the housing, and configured to sense a fingerprint of a user touching the transparent member,
• wherein the biometric sensor module comprises:
• a plurality of light emitting devices configured to emit light toward the transparent member;
• an image sensor disposed to face one surface of the light blocking member, and configured to sense light reflected from an external object;
• and
• a pin-hole structure formed inside or near to the light blocking member, and configured to provide a path for the reflected light directed toward the image sensor.

A biometric sensor module comprising:

• a plurality of light emitting devices configured to emit light toward the outside;
• an image sensor disposed to face at least part of arrangement of the plurality of light emitting devices, and configured to sense the emitted light after the emitted light is reflected from a user's body;
• and
• a pin-hole structure disposed between the plurality of light emitting devices and the image sensor, and configured to guide a path of the reflected light directed toward the image sensor,
• wherein the pin-hole structure comprises:
• a plurality of pin holes arranged apart from each other by a predetermined gap in an area facing the image sensor, and
• a plurality of walls, each disposed between pin holes, and configured to block interference of the reflected light.
