Flüssigkristall-Anzeigevorrichtung Die vorliegende Erfindung betrifft eine Flüssigkristall-Anzeigevorrichtung gemäß dem Oberbegriff des Patentanspruches 1.Liquid crystal display device The present invention relates to a liquid crystal display device according to the preamble of the claim 1.
Transflektiv betreibbare Flüssigkristallanzeigen, die sowohl bei Dunkelheit als auch bei Helligkeit ablesbar sind, weisen vom Betrachter aus gesehen, auf der Rückseite einen teildurchlässigen Spiegel (Transflektor) und eine Beleuchtungseinrichtung auf. Derartige Flüssigkristallanzeigen sind universell z. B. in Kraftfahrzeugen, Bahnhö-£ein, Abl'cr tiguiigshalluii uiid dergleichen einsetzbar. Je nach Verwendungszweck stellt sich die Forderung einzelnen elektrisch steuerbaren Zahlenfenstern, Stufenskalen usw.Transflectively operable liquid crystal displays, which can be used both in the dark as well as can be read at brightness point, seen from the viewer, on the Backside a partially transparent mirror (transflector) and a lighting device on. Such liquid crystal displays are universal z. B. in motor vehicles, Railway stations- £ a, Abl'cr tiguiigshalluii uiid the like can be used. Depending on the intended use The requirement arises for individual electrically controllable number windows, graduated scales etc.
unterschiedliche Festwerte wie z.B. physikalische Einheiten, Festskalen zuzuordnen. Zu diesem Zweck ist bereits vorgeschlagen worden, Festzeichen auf die Frontseite der Flüssigkristallzelle aufzudrucken oder durch entsprechende Formgebung und Gestaltung der Elektroden darzustellen. Dies bedeutet, daß für die einezelnen Verwendungszwecke spezielle Flüssigkristallzellen herzustellen sind.different fixed values such as physical units, fixed scales assign. For this purpose it has already been proposed to use fixed characters on the To be printed on the front of the liquid crystal cell or by appropriate shaping and design of the electrodes. This means that for the individual uses are to manufacture special liquid crystal cells.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde Flüssigkristall-Anzeigevorrichtungen der eingangs genannten Art vorzusehen, die wesentlich universeller einsetzbar sind und daher rationeller herstellbar sind.The present invention is based on the object of liquid crystal display devices of the type mentioned above, which can be used much more universally and can therefore be produced more efficiently.
Diese Aufgabe wird durch die im Kennzeichen des Patentanspruches 1 angegebenen Merkmale gelöst.This task is achieved by the characterizing part of claim 1 specified features solved.
Die beschriebeiie Flüssigkristallanzeige ermöglicht bei gleichem elektrisch steuerbarem Anzeigeinhalt, wie z. B.The beschreibeiie liquid crystal display enables the same electrical controllable display content, such as B.
Linear- und Digit alanzeigefenstern das Anbringen unterschiedlicher Skalierungen und Festzeichenangaben, die gegebenenfalls sogar durch den Kunden durch einfaches Einsetzen oder Auswechseln eines Baut eins durchführbar sind. So kann z. B. einer Linearanzeige einmal eine in Grad Celsius und ein andermal eine in Volt elektrischer Spannung geeichte Skala lediglich durch Austauschen des Transflektors zugeordnet werden. Der Transflektor ist ein verhältnismäßig einfaches Bauteil, das ohne große Schwieringkeiten, z. 13. durch Bedrucken mit entsprechenden Fest -zeichen, Skalierungen, Beschriftungen und dergleichen versehen werden kann.Linear and digital display windows allow the attachment of different Scalings and fixed character information, which may even be carried out by the customer simple insertion or replacement of a component are feasible. So can z. B. a linear display once one in degrees Celsius and another time one in volts Electric voltage calibrated scale simply by exchanging the transflector be assigned. The transflector is a relatively simple component that without much difficulty, e.g. 13. by printing with the appropriate fixed characters, Scales, labels and the like can be provided.
Anhand des in der Figur schematisch dargestellten Ausführungsbeispiels wird die Erfindung näher erläutert.On the basis of the exemplary embodiment shown schematically in the figure the invention is explained in more detail.
Die Figur ausschnittsweise einen Querschnitt durch eine Flüssigkristallzelle mit Transflektor 7, der auf der dem Betrachter 11 abgewandten Seite der Flüssigkristallzelle mit den Polarisatoren 4 und 5, den transparenten Glassubstraten oder Folien 2 und 3 und der Flüssigkristallschicht 1 angeordnet ist. Hinter der Flüssigkristallzelle ist eine ßeleuchtungsquelle 10 für den Betrieb bei Dunkelheit vorgesehen.The figure shows a detail of a cross section through a liquid crystal cell with transflector 7 on the side of the liquid crystal cell facing away from the viewer 11 with the polarizers 4 and 5, the transparent glass substrates or foils 2 and 3 and the liquid crystal layer 1 is arranged. Behind the liquid crystal cell a light source 10 is provided for operation in the dark.
Gemäß der Erfindung ist nun der Transflektor 7 mit einer Festzeichenmarkierung 8 versehen. Der Transflektor ist bevorzugt leicht auswechselbar an der Flüssigkristallzelle befestigt.According to the invention, the transflector 7 is now marked with a fixed character 8 provided. The transflector is preferably easily exchangeable on the liquid crystal cell attached.
Arbeitet die Flüssigkristallzelle im Negativanzeigemodus (helle Symbole auf dunklem Grund), so ist auch das Festzeichen 8 auf dem Transflektor 7 im Negativdruck aufzubringen. Umgekehrt ist das Festzeichen 8 im Positivdruck (dunkles Symbol auf hellem Grund) auf dem Transflektor 7 anzubringen, wenn die Flüssigkristallzelle im Positivanzeigemodus arbeitet.If the liquid crystal cell operates in negative display mode (light icons on a dark background), the fixed mark 8 on the transflector 7 is also in negative print to raise. Conversely, the fixed character 8 is in positive printing (dark symbol on light background) to be attached to the transflector 7 if the liquid crystal cell works in positive display mode.
In der Figur ist eine Vorrichtung dargestellt, bei der das Festzeichen 8 auf den TrallsJlektor 7 elektrisch nicht schaltbar ist, weil durch entsprechend eingefügte Stege 12 dafür Sorge getragen ist, daß vor den Festzeichen 8 sich ein von Flüssigkristallmaterial freier Raum 9 befindet.In the figure, a device is shown in which the fixed character 8 on the TrallsJlektor 7 is not electrically switchable, because accordingly inserted webs 12 ensure that in front of the fixed characters 8 a of liquid crystal material free space 9 is located.
Es ist ebenso möglich, in der Flüssigkristallzelle vor dem Festzeichen durch transparente Elektroden steuerbares Flüssigkristallmaterial 1 vorzusehen, z. B. durch Weglassen der Trennstege 12. In diesem Fall ist es möglich, das Festzeichen z. B. in die Zustände sichtbar und unsichtbar zu schalten.It is also possible in the liquid crystal cell before the solid character to provide liquid crystal material 1 controllable by transparent electrodes, z. B. by omitting the separators 12. In this case it is possible to use the fixed characters z. B. to switch to the states visible and invisible.
