Abstract

L’invention concerne un écran optique (1) comprenant des motifs de découplage de lumière (100) pour réaliser une fonction de signalisation (F1) pour un véhicule (2), caractérisé en ce que ledit écran optique (1) comprend deux pièces (11, 12) d’indices de réfraction (r1, r2) sensiblement identiques :- dont l’une des pièces (11, 12) au moins comprend lesdits motifs de découplage de lumière (100),- ledit écran optique (1) étant configuré pour prendre deux états (s1, s2) dont :- un état de signalisation (s1) dans lequel les deux pièces (11, 12) sont séparées par un matériau d’indice de réfraction différent de leurs indices de réfraction respectifs (r1, r2),- un état neutre (s2) dans lequel ledit écran optique (1) possède un indice de réfraction sensiblement constant dans son volume. Figure pour abrégé : Fig. 1The invention relates to an optical screen (1) comprising light decoupling patterns (100) for performing a signaling function (F1) for a vehicle (2), characterized in that said optical screen (1) comprises two parts ( 11, 12) of substantially identical refractive indices (r1, r2): - at least one of the parts (11, 12) comprises said light decoupling patterns (100), - said optical screen (1) being configured to take two states (s1, s2) including: - a signaling state (s1) in which the two parts (11, 12) are separated by a material with a refractive index different from their respective refractive indices (r1, r2), - a neutral state (s2) in which said optical screen (1) has a refractive index substantially constant in its volume. Figure for abbreviation: Fig. 1
