Abstract

Abstract Translated from German An drei Seiten eines glasklaren, z.B. plattenförmigen, Lichtleiters (1) werden Fluoreszenzkörper (3) in verschiedenen Fluoreszenzfarben angebracht. Die Fluoreszenzkörper (3) sind vom Lichtleiter (1) durch Lichtventile (2) (z.B. Flüssigkristallzellen) getrennt. Im lichtdurchlässigen Schaltzustand des Lichtventils (2) wird der Lichtleiter(1) mit dem Licht der jeweiligen Fluoreszenzfarbe geflutet. Dadurch lassen sich mit nur einer Anzeige, die sich hinter dem Lichtleiter befindet, verschiedenfarbige Informationen darstellen. On three sides of a crystal clear, e.g. plate-shaped, light guide (1), fluorescent bodies (3) are attached in different fluorescent colors. The fluorescent bodies (3) are separated from the light guide (1) by light valves (2) (e.g. liquid crystal cells). In the translucent switching state of the light valve (2), the light guide (1) is flooded with the light of the respective fluorescent color. As a result, different colored information can be displayed with just one display, which is located behind the light guide.
