Abstract

Die Erfindung betrifft eine LCD-Pixelmatrixanzeige deren Helligkeit bzw. Kontrast steuerbar ist. Dies wird zum einen durch Änderung der LCD-Steuerspannung entsprechend der Umgebungshelligkeit erreicht. Die LCD-Steuerspannung wird bei höherer Umgebungshelligkeit zu höheren Werten verschoben, wodurch die Trasmisivität der LCD-Anzeige steigt. Hierdurch erscheint die Anzeige heller und ist bei höherer Umgebungshelligkeit besser ablesbar bzw. erkennbar. Alternativ läßt sich die bessere Ablesbarkeit auch durch dadurch erreichen, daß das Verhältnis von aktiver Fläche zur gesamten Anzeige im Flächenbereich zwischen 40% und 95%, vorzugsweise im Bereich zwischen 50% und 87% und insbesondere im Bereich zwischen 60% und 85% liegt, wobei Pixeldichten mit 2 bis 3 Pixel pro Quadratzentimeter vorgesehen sind.
