Abstract

Dispositif de projection d’images Un aspect de l’invention concerne un dispositif de projection d’images (5) comprenant :- une source lumineuse (6) d’émission d’un faisceau source (FS), - un système optique d’éclairage (7) apte à recevoir et transformer le faisceau source (FS) en un faisceau homogène (FH), - une image à projeter (Im) placée sur le trajet du faisceau homogène (FH) et apte à réfléchir le faisceau homogène (FH) en un faisceau réfléchi (FR), - un système optique de projection (8) placé sur le trajet du faisceau réfléchi (FR) et apte à projeter l’image à projeter (Im), l’image à projeter (Im) comportant une structure multicouche (S) comprenant un substrat (2), une couche métallique (3), et une couche de matériau organique électrochrome (4) structurée en une pluralité d’éléments, chaque élément étant encapsulé dans une couche d’électrolyte et connecté à une paire d’électrodes apte à recevoir une tension, l’image à projeter (Im) étant déterminée par la tension aux bornes de chaque paire d’électrodes. Figure à publier avec l’abrégé : Figure 2
