Electronic device
Disclosed is an electronic device. In the electronic device according to the present disclosure, a central axis of a viewing angle based on an eye of a user and the central axis of the viewing angle based on a lens optical axis of a camera match each other. An electronic device according to the present disclosure may be associated with an artificial intelligence module, robot, augmented reality (AR) device, virtual reality (VR) device, and device related to 5G services.
1. An electronic device comprising:
a display including a see-through function;
a control unit configured to cause the display to display content;
a camera comprising an image sensor and configured to acquire images of an environment around the electronic device; and
a reflector formed in the display and comprising:
a first concave mirror including a first concave reflection surface facing an eye of a user and reflecting the content to the eye of the user; and
a second concave mirror including a second concave reflection surface facing the camera and reflecting light incident on the display from an exterior of the electronic device toward the camera,
wherein the first and second concave mirrors respectively comprise a pin-mirror and are disposed back-to-back to each other, and
wherein the first concave reflection surface has a first curvature and the second concave reflection surface has a second curvature to suppress generation of double images.
2. The electronic device of claim 1 , wherein a transparent optical glue is deposited between the first concave mirror and the second concave mirror.
3. The electronic device of claim 1 , wherein the first curvature and the second curvature are equal to each other.
4. The electronic device of claim 1 , wherein the first curvature is larger than the second curvature.
5. The electronic device of claim 1 , wherein the first curvature is smaller than the second curvature.
6. The electronic device of claim 1 , wherein the control unit is disposed at a first end of the display and the camera is disposed at a second end of the display opposite the first end such that the control unit and the camera face each other.
7. The electronic device of claim 6 , wherein the control unit is disposed at an upper end of the display and the camera is disposed at a lower end of the display, and
wherein the camera is disposed downward from the eye of the user along a vertical axis perpendicular to an optical axis of the eye of the user.
8. The electronic device of claim 7 , wherein the reflector is spaced apart from the control unit by a first distance and spaced apart from the camera by a second distance.
9. The electronic device of claim 8 , wherein the first distance is equal to the second distance.
10. The electronic device of claim 8 , wherein the first distance is greater than the second distance.
11. The electronic device of claim 8 , wherein the first distance is less than the second distance.
12. The electronic device of claim 1 , further comprising:
a lens array configured to focus the light reflected from the second concave reflection surface toward the camera.
