Abstract

L'invention porte sur un dispositif d'affichage pouvant être réduit en épaisseur et permettant à un observateur d'observer une image agrandie. Le dispositif d'affichage comporte une plaque de guidage de lumière, un élément d'affichage, un élément de réflexion non régulier et une lentille. La plaque de guidage de lumière possède deux surfaces opposées l'une à l'autre, de telle sorte que l'intervalle entre les extrémités des deux surfaces sur un côté est différent de l'intervalle entre les autres extrémités de celles-ci. L'élément d'affichage est disposé dans une position telle que la lumière de sortie est totalement réfléchie entre les deux surfaces. L'élément de réflexion non régulier est disposé sur l'une des deux surfaces, à partir de laquelle la lumière totalement réfléchie est délivrée en sortie. La lentille délivre en sortie la lumière à partir de l'élément de réflexion non régulier dans une direction d'axe optique. Il est souhaitable que le flux lumineux délivré en sortie à partir de la plaque de guidage de lumière soit réfracté par l'élément de réflexion non régulier et amené à être incident sur la lentille.
