Abstract

Eine Anzeigevorrichtung ist mit einem Gehäuseelement (2), das eine Lichtaustrittsöffnung (3) hat, einer ersten Leuchtdiode (5) einer ersten Lichtfarbe, und einer zweiten Leuchtdiode (6) einer von der ersten Lichtfarbe verschiedenen zweiten Lichtfarbe ausgestattet. Hierbei sind die erste und die zweite Leuchtdiode (5, 6) separat ansteuerbar und die erste und die zweite Leuchtdiode (5, 6) sind im Wesentlichen quer zu einer Lichtaustrittsrichtung der Lichtaustrittsöffnung (3) so angeordnet, dass sie sich gegenseitig beleuchten können. Aufgrund dieser Anordnung wird ein Teil des von der einen Leuchtdiode (5) abgestrahlten Lichts durch Reflexion an der anderen Leuchtdiode (6) in den lichtdurchlässigen Bereich (3) gelenkt.

A display device is equipped with a housing element (2) which has a light exit opening (3), a first light-emitting diode (5) of a first light color, and a second light-emitting diode (6) of a second light color different from the first light color. In this case, the first and the second light-emitting diode (5, 6) can be controlled separately and the first and the second light-emitting diode (5, 6) are arranged substantially transversely to a light exit direction of the light exit opening (3) so that they can illuminate each other. By virtue of this arrangement, a part of the light emitted by one light-emitting diode (5) is deflected by reflection at the other light-emitting diode (6) into the light-permeable region (3).
