Abstract

Die Erfindung geht aus von einer Wiedergabeeinrichtung zur optischen Wiedergabe von Informationen an insbesondere einen menschlichen Betrachter, insbesondere zur Anzeige von Zuständen oder Schaltstellungen, mit einem Grundelement, mit einer an dem Grundelement angeordneten Lichtquelle und mit wenigstens einem die wiederzugebende Information wiedergebenden, von der Lichtquelle ausleuchtbaren Piktogramm.The invention is based on a playback device for the optical reproduction of information in particular a human viewer, especially for displaying States or switching positions, with a basic element, with a light source arranged on the base element and with at least one the information to be reproduced reproducing, illuminable by the light source Pictogram.

Die Erfindung zeichnet sich dadurch aus, dass das Grundelement eine Grundfolie ist, dass als Lichtquelle eine Leuchtpigmentschicht vorhanden ist, dass eine dem Betrachter zugewandte erste Elektrode und eine dem Betrachter abgewandte Rückelektrode vorhanden ist, wobei die Leuchtpigmentschicht zwischen den beiden Elektroden angeordnet ist, dass durch Anlegen einer Spannung an die Elektroden die Leuchtpigmentschicht wenigstens abschnittsweise zum Leuchten gebracht werden kann und dass auf der dem Betrachter zugewandten Seite der Leuchtpigmentschicht eine undurchsichtige Abdeckschicht vorhanden ist, welche durchsichtige Aussparungen in Form und Größe des wenigstens einen Piktogramms aufweist.

Figure 00000001
The invention is characterized in that the basic element is a base film, that there is a luminous pigment layer as the light source, that there is a first electrode facing the viewer and a back electrode facing away from the viewer, the luminous pigment layer being arranged between the two electrodes Applying a voltage to the electrodes can illuminate the luminescent pigment layer at least in sections and that on the side of the luminescent pigment layer facing the viewer there is an opaque covering layer which has transparent cutouts in the shape and size of the at least one pictogram.
