Abstract
(DE) Die Erfindung betrifft eine Mehrlagen-Bildanzeigevorrichtung mit zumindest folgenden entlang einer Längserstreckungsrichtung von hinten nach vorne in dieser Reihenfolge angeordneten Komponenten: a) eine Lichtquelle (16), b) eine erste Flüssigkristallschicht (214) und c) eine zweite Flüssigkristallschicht (224), wobei der ersten Flüssigkristallschicht mindestens ein Polarisationsfilter (210, 212) beigeordnet ist und der zweiten Flüssigkristallschicht mindestens ein Polarisationsfilter (220, 222) beigeordnet ist, wobei das Licht der Lichtquelle ferner durch mindestens ein optisches und/oder elektro-optisches Retardationselement (230, 221, 260) geleitet wird, bevor es einen Betrachter erreicht.
(EN) The invention relates to a multilayer image display device comprising at least the following components arranged along a longitudinal extension direction from the rear toward the front in this order: a) a light source (16), b) a first liquid crystal layer (214), and c) a second liquid crystal layer (224), wherein at least one polarization filter (210, 212) is assigned to the first liquid crystal layer and at least one polarization filter (220, 222) is assigned to the second liquid crystal layer, wherein the light from the light source is furthermore guided through at least one optical and/or electro-optical retardation element (230, 221, 260) before it reaches an observer.
(FR) L'invention concerne un dispositif d'affichage d'image multicouche comportant au moins les composants suivants disposés le long d'une direction longitudinale de l'arrière vers l'avant dans l'ordre suivant : a) une source de lumière; b) une première couche de cristal liquide; c) une deuxième couche de cristal liquide, un filtre polarisant au moins étant affecté à la première couche de cristal liquide et un filtre polarisant au moins étant affecté à la deuxième couche de cristal liquide, la lumière de la source de lumière étant acheminée en outre à travers au moins un élément optique et/ou électro-optique de retard, avant d'atteindre un observateur.
