Abstract
(EN)
To overcome the difficulty of manufacturing a pin mirror or a pin hole inside an optical element, the present disclosure provides an electronic device comprising an optical element forming an inner side surface facing a user's eye and an outer side surface that is a back surface of the inner side surface, an optical driving assembly configured to inject image light into one side of the optical element, a reflection member provided in the optical element to reflect at least a part of the injected image light, and a pin hole/mirror member provided in one region of the inner side surface or the outer side surface of the optical element to deepen a depth by reflecting or transmitting the image light reflected by the reflection member.
(FR)
La présente invention concerne, pour surmonter la difficulté de fabrication d'un miroir de broche ou d'un trou de broche à l'intérieur d'un élément optique, un dispositif électronique comprenant un élément optique formant une surface latérale interne faisant face à l’œil d'un utilisateur et une surface latérale externe qui est une surface arrière de la surface latérale interne, un ensemble d'entraînement optique configuré pour injecter une lumière d'image dans un côté de l'élément optique, un élément de réflexion situé dans l'élément optique pour réfléchir au moins une partie de la lumière d'image injectée, et un élément de trou/miroir de broche situé dans une région de la surface latérale interne ou externe de l'élément optique pour approfondir une profondeur par réflexion ou transmission de la lumière d'image réfléchie par l'élément de réflexion.
