Abstract

Dispositif d'affichage (100) qui comporte :- au moins un afficheur « latéral», placé après la surface d'affichage du dispositif, apte à afficher un message, et qui comporte :- un guide d'onde composé d'un substrat (110, 160) transparent ou translucide, portant un message à afficher composé d'au moins une zone « message » (111, 161) placée sur une des surfaces du substrat,- au moins une source de lumière (141, 191) adaptée à éclairer latéralement le guide d'onde,- au moins un filtre «négatif» (120, 170), couvrant au moins partiellement les zones « message » (111, 161) du guide d'onde, placé après le guide d'onde, les zones en superposition des zones « message » étant transparentes et les zones complémentaires (121, 122, 171, 172) aux zones « message » ayant une fonction de transmission équivalente à celle des zones « message » et- un moyen de modulation (150) d'au moins une caractéristique physique d'une source de lumière d'un afficheur, de telle manière que, lorsque la source de lumière d'un afficheur est allumée, les rayons lumineux émis se propagent à l'intérieur du substrat correspondant jusqu'aux zones « message ». Ces dites zones réfléchissent une partie et/ou transmettent une autre partie des ces rayons lumineux, en dehors du substrat correspondant.Display device (100) which comprises: - at least one "side" display, placed after the display surface of the device, capable of displaying a message, and which comprises: - a waveguide composed of a substrate (110, 160) transparent or translucent, carrying a message to be displayed composed of at least one “message” zone (111, 161) placed on one of the surfaces of the substrate, - at least one suitable light source (141, 191) to illuminate the waveguide laterally, - at least one “negative” filter (120, 170), at least partially covering the “message” areas (111, 161) of the waveguide, placed after the waveguide , the zones superimposed on the “message” zones being transparent and the additional zones (121, 122, 171, 172) to the “message” zones having a transmission function equivalent to that of the “message” zones and a modulation means ( 150) of at least one physical characteristic of a light source of a display, such that when the light source When a display is on, the light rays emitted propagate inside the corresponding substrate as far as the “message” zones. These said zones reflect a part and / or transmit another part of these light rays, outside the corresponding substrate.
