Abstract

Un dispositif électronique traditionnel comportant un viseur stéréo rencontre de nombreux problèmes lors d'une commutation entre un affichage 2D (affichage normal) et un affichage 3D (affichage tridimensionnel), et possède de mauvaises caractéristiques de transport du fait de la difficulté à réduire son épaisseur. Un boîtier de l'élément d'affichage et un cache de boîtier sur la surface arrière sont connectés l'un à l'autre par un premier arbre rotatif, le cache et une lentille binoculaire étant connectés l'un à l'autre par un second arbre rotatif, et le cache et la lentille binoculaire pouvant tourner d'environ 270 degrés l'un par rapport à l'autre, respectivement, de manière à réaliser un affichage 3D, dans lequel la lentille binoculaire est disposée en parallèle à l'élément d'affichage, et un affichage 2D, dans lequel la lentille binoculaire est contenue dans le boîtier, en même temps, ce qui permet d'obtenir un dispositif électronique à affichage 3D fin et facilement portable.
