Abstract

L'invention concerne un ensemble d'affichage autostéréoscopique et un appareil d'affichage autostéréoscopique. L'ensemble d'affichage autostéréoscopique comprend une structure de cadre tridimensionnelle (300, 500) ; la structure de cadre tridimensionnelle (300, 500) comprend un élément de blindage et un élément de montage, l'élément de blindage étant disposé sur l'élément de montage, l'élément de blindage étant utilisé pour protéger une région de bord (221, 421) d'un écran d'affichage (220, 420), et l'élément de protection étant pourvu d'une ouverture de visualisation pour exposer au moins partiellement une région d'affichage (222) de l'écran d'affichage (220, 420) ; et l'élément de montage est utilisé pour monter et placer l'élément de blindage à l'opposé de l'écran d'affichage (220, 420), de telle sorte qu'une distance prédéfinie est formée entre l'extrémité de l'élément de blindage à distance de l'écran d'affichage (220, 420) et l'écran d'affichage (220, 420).
