Abstract

Die Erfindung betrifft eine Anzeigevorrichtung (1), durch deren Anzeige (4), welche bereichsweise transparent schaltbar ist, der dahinter befindliche Hintergrund (31) erkennbar ist. The invention relates to a display device (1) through whose display (4), which is partially transparent switchable, the background behind it (31) can be seen. Derartige Anzeigevorrichtungen (1) finden bisher in beispielsweise Kraftfahrzeugen (2) keine Anwendung, da die ständig wechselnden Lichtverhältnisse, insbesondere im Hintergrund (31) der Anzeige (4), die Ablesbarkeit beeinträchtigen. Such display devices (1) found so far in, for example, motor vehicles (2) do not apply, since the constantly changing light conditions, in particular (31) in the background of the display (4), interfere with the readability. Zur Lösung dieses Problems schlägt die Erfindung vor, dass die Anzeige (4) einen ersten schaltbaren Filter aufweist, welcher zwischen einer im Wesentlichen diffusen, zumindest teilweisen Transmission und einer im Wesentlichen transparenten, zumindest teilweisen Transmission hin- und her schaltbar ist. To solve this problem, the invention proposes that the display (4) comprises a first switchable filter which between a substantially diffuse at least partial transmission and substantially transparent, at least partially back and forth transmission switchable. Als erster Filter (10) ist ein PDLCD (11) bevorzugt. As the first filter (10) is a PDLCD (11) are preferred. Daneben ist ein Verfahren zum Betrieb der erfindungsgemäßen Anzeigevorrichtung (1) Gegenstand der Erfindung. In addition, a method for operating the display device according to the invention (1) is the subject of the invention.
