Abstract: An electronic device is disclosed. The electronic device of the present disclosure includes a light emitting unit for providing image light, and a display unit for reflecting the image light and transmitting the reflected image light to eyes of a user. The display unit includes a lens unit and a reflective surface for reflecting the image light. The reflective surface is formed of a 3-dimensional curved surface having different curvatures in a first direction and in a second direction perpendicular to the first direction, thereby correcting astigmatism. An electronic device according to the present invention may be associated with an artificial intelligence module, robot, augmented reality (AR) device, virtual reality (VR) device, and device related to 5G services.

Abstract: In order to provide an optical device for clearly implementing augmented reality provided from a display unit, regardless of a change in a focal point of an outer mirror through which a user views, the present invention comprises: the display unit for emitting an optical beam displaying an image; transparent glass through which external light passes and which forms the path of the optical beam emitted by the display unit; and a pinhole mirror disposed to the glass, and disposed on the path of the optical beam emitted by the display unit, so as to reflect the optical beam emitted by the display unit, wherein the pinhole mirror has a polygonal shape and has an area less than that of the pupil so that an image formed by the optical beam emitted by the display unit overlaps with an image formed by the external light having been transmitted through the glass.

Abstract: A spatial image projection apparatus including a receiver configured to receive an image signal; a display unit configured to display an image acquired by processing the image signal; a projection unit configured to project a spatial image to a prescribed space by transmitting or reflecting light corresponding to the image displayed on the display unit; and an optical-path length-converter located between the display unit and the projection unit so as to change an optical-path length of the image. Further, the optical-path length-converter includes a polarizer configured to transmit only specific polarized light, among the light introduced from the display unit, toward the projection unit, and to reflect the remaining light other than the specific polarized light; and a mirror configured to transmit light, introduced from the display unit, to the polarizer, and to convert the light reflected from the polarizer into specific polarized light so as to again reflect the light to the polarizer.
