Abstract

L'invention porte sur un dispositif d'affichage comportant : un panneau d'affichage (11) qui affiche une image ; un panneau de conversion photoélectrique (12) qui convertit une lumière reçue en énergie électrique ; et un mécanisme de commutation (13) qui, dans une région prédéterminée de la surface avant du dispositif (Fr), commute entre un état dans lequel le panneau d'affichage (11) est disposé en regard de la surface avant du dispositif (Fr) et un état dans lequel le panneau de conversion photoélectrique (12) est disposé en regard de la surface avant du dispositif (Fr). Dans ce cas, au moyen du mécanisme de commutation (13), dans une région prédéterminée de la surface avant du dispositif (Fr), il est possible de commuter entre l'état dans lequel le panneau d'affichage (11) est disposé en regard de la surface avant du dispositif (Fr) et l'état dans lequel le panneau de conversion photoélectrique (12) est disposé en regard de la surface avant du dispositif (Fr).
