Abstract

L'invention concerne un afficheur d'images comportant également une fonction de projecteur, mais cela n'entraîne pas une augmentation de taille relative à la forme du corps principal et, par ailleurs, le risque d'une d'application de faisceau laser au corps humain est totalement inexistant. L'invention concerne également un terminal portable. On décrit un afficheur d'images comportant une source de lumière laser (101); un système optique (lentilles de diffraction (103 et 104) et un élément à cristaux liquides à polymères dispersés (105)) qui peut être basculé en mode de vision directe, ce qui permet de moduler un faisceau laser destiné à être affiché sur un étage d'affichage, ou en mode de projection, ce qui permet de moduler un faisceau laser destiné à être projeté sur une surface prévue à cet effet; et, enfin, un circuit de commande (attaque des cristaux liquides (202)) contrôlant le système optique. Le circuit de commande est mis en mode de vision directe lorsque la source d'alimentation est activée.
