Abstract

L'invention concerne un dispositif d'affichage utilisant un dispositif d'affichage transparent et un hologramme. Un dispositif d'affichage selon un mode de réalisation de la présente invention comprend un hologramme pour générer une image virtuelle d'une exposition et un dispositif d'affichage transparent situé entre l'hologramme et un observateur. En conséquence, la présente invention utilise un hologramme pouvant reproduire un effet d'une exposition comme si c'était le cas sans exposition réelle, ce qui peut réduire le volume du dispositif d'exposition, permettant ainsi de réduire considérablement un espace d'exposition.
