Abstract

Die Erfindung betrifft einen Flüssigkristallbildschirm (1), aufweisend einen Signaleingang (4) zum Empfangen eines Bildsignals von einer Bildsignalquelle (3), eine Flüssigkristallanzeige (7) mit einer Vielzahl von Bildpunkten (8), eine mit dem Signaleingang (4) und der Flüssigkristallanzeige (7) verbundene Ansteuervorrichtung (6) zum Ansteuern der Vielzahl von Bildpunkten (8) in Abhängigkeit des empfangenen Bildsignals und eine mit der Ansteuervorrichtung (6) verbundene Übersteuerungsvorrichtung (11), die dazu eingerichtet ist, wenigstens einige der Vielzahl von Bildpunkten (8) zu übersteuern. Der Flüssigkristallbildschirm (1) ist gekennzeichnet durch eine mit der Ansteuervorrichtung (6) verbundene Farbtemperaturwahlvorrichtung (12), die dazu eingerichtet ist, eine Farbtemperatur (33) für den Flüssigkristallbildschirm (1) festzulegen, und eine mit der Übersteuerungsvorrichtung (11) und der Farbtemperaturwahlvorrichtung (12) verbundene Betriebsartwahlvorrichtung (13), die dazu eingerichtet ist, eine Betriebsart (31) des Flüssigkristallbildschirms (1) auszuwählen und in Abhängigkeit der ausgewählten Betriebsart (31) die Übersteuerungsvorrichtung (11) und die Farbtemperaturwahlvorrichtung (12) anzusteuern.The present invention relates to a liquid crystal panel (1) comprising a signal input (4) for receiving an image signal from an image signal source (3), a liquid crystal display (7) having a plurality of pixels (8), one having the signal input (4) and the liquid crystal display (7) connected drive device (6) for driving the plurality of pixels (8) in response to the received image signal and an override device (11) connected to the drive device (6), which is adapted to at least some of the plurality of pixels (8) to oversteer. The liquid crystal panel (1) is characterized by a color temperature selection device (12) connected to the drive device (6) arranged to set a color temperature (33) for the liquid crystal panel (1) and one having the override device (11) and the color temperature selection device (12) associated mode selection means (13) adapted to select a mode (31) of the liquid crystal panel (1) and to control the override device (11) and the color temperature selection device (12) depending on the selected mode (31).

Die Erfindung betrifft außerdem ein Verfahren zur Anzeige eines Bildsignals durch einen Flüssigkristallbildschirm (1).
