Description
Die vorliegende Erfindung betrifft eine Flüssigkristall- Anzeigevorrichtung nach dem Oberbegriff des Pa tentanspruchs 1.The present invention relates to a liquid crystal Display device according to the preamble of Pa claim 1.
Derartige Flüssigkristall-Anzeigevorrichtungen sind z B. aus der DE-OS 36 33 565 bekannt. Es ist ferner bekannt FK- Anzeigezellen so auszubilden, daß sie reflektiv transmis siv oder transflektiv betreibbar sind. Auch ist es bekannt in Flüssigkristalltechnik Matrixanzeigevorrichtungen her zustellen.Such liquid crystal display devices are e.g. known from DE-OS 36 33 565. It is also known FK- Form display cells so that they are transmissively reflective are operable siv or transflective. It is also known in liquid crystal technology matrix display devices deliver.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde eine neuartige Anzeigevorrichtung der eingangs genannten Art anzugeben, die eine Matrixanzeige ermöglicht, für unter schiedliche Betriebsarten wie transflektiv, transmissiv oder reflektiv geeignet ist und für Großanzeigetafeln ge eignet ist.The present invention is based on the object novel display device of the type mentioned specify that allows a matrix display for under different operating modes such as transflective, transmissive or is reflective and suitable for large display boards is suitable.
Diese Aufgabe wird durch die im Kennzeichen des Pa tentanspruchs 1 angegebenen Merkmale gelöst.This task is carried out by the Pa Features specified 1 solved.
Anhand des in den Fig. 1 und 2 dargestellten Ausfüh rungsbeispiels wird die Erfindung nachfolgend näher erläu tert.On the basis of the example shown in FIGS . 1 and 2, the invention is explained in more detail below.
Die Fig. 1 zeigt eine Aufsicht auf die Rückseite einer Flüssigkristall-Anzeigezelle die ein Anzeigeelement der beschriebenen Flüssigkristall-Anzeigevorrichtung bildet. Fig. 1 shows a plan view of the back of a liquid crystal display cell which forms a display element of the liquid crystal display device described.
Die Fig. 2 zeigt ausschnittsweise eine teilweise ge schnittene Seitenansicht einer erfindungsgemäßen Anzeige vorrichtung von der zwei Flüssigkristall-Anzeigezellen zu sehen sind. Fig. 2 shows a partial ge cut side view of a display device according to the invention of the two liquid crystal display cells can be seen.
Die in Fig. 1 gezeigte Flüssigkristall-Zelle besitzt rechteckige, insbesondere quadratische Außenmaße. Während die Frontscheibe die genannten Formen aufweist, sind an der Rückplatte 1 die Ecken 2 abgeschnitten, so daß an die sen Stellen von hinten die Frontplatte mit den darauf be findlichen, aus der Flüssigkristall-Zelle herausgeführten Kontaktierungsflächen 3 sichtbar sind. Diese Kontaktie rungsflächen 3 sind aus der Flüssigkristall-Zelle heraus geführt und ermöglichen die äußere Kontaktierung der im Innern der Flüssigkristall-Zelle befindlichen Elektroden zur Steuerung der optischen Beeinflussung der in der Zelle befindlichen Flüssigkristallschicht, in an sich bekannter Weise.The liquid crystal cell shown in FIG. 1 has rectangular, in particular square, external dimensions. While the windscreen has the forms mentioned, the corners 2 are cut off at the back plate 1, so that the front plate with the be out-sensitive, guided out of the liquid crystal cell contacting surfaces 3 are visible to the sen points from the rear. These contact surfaces 3 are guided out of the liquid crystal cell and enable the external contacting of the electrodes located in the interior of the liquid crystal cell to control the optical influencing of the liquid crystal layer located in the cell, in a manner known per se.
Aus der in der Fig. 2 dargestellten Seitenansicht ist eine Anzeigevorrichtung mit zwei der in Fig. 1 gezeigten Flüssigkristallzellen zu erkennen. Eine solche Anzeigeein heit kann eine Vielzahl von Zellen umfassen. Gleiche Teile sind mit gleichen Ziffern bezeichnet. Jede Flüssigkri stall-Zelle besitzt eine Frontplatte 4 und eine Rückplatte 1 mit der dazwischen befindlichen Flüssigkristallschicht 6. Die Rückplatten 1 weisen die abgekappten Ecken 2 auf, so daß die Kontaktierungsflächen 3 auf der Frontplatte 4 zugänglich sind. Beide Deckplatten 1, 4 der FK-Zellen be stehen aus Glas oder einem glasartigen Kunststoff.A display device with two of the liquid crystal cells shown in FIG. 1 can be seen from the side view shown in FIG. 2. Such a display unit can comprise a plurality of cells. The same parts are labeled with the same numbers. Each liquid crystal cell has a front panel 4 and a back panel 1 with the liquid crystal layer 6 therebetween. The back plates 1 have the cut corners 2 , so that the contact surfaces 3 on the front plate 4 are accessible. Both cover plates 1 , 4 of the FK cells are made of glass or a glass-like plastic.
Zur Bildung einer Vorrichtung mit mehreren Flüssigkri stall-Zellen sind zumindest eine Trägerplatte 5, 9 vorge sehen, die ebenfalls aus einem glasartigen Material wie Glas oder Kunststoff bestehen und durchsichtig sind. Diese Trägerplatten 5, 9 sind mittels eines optischen Klebers 7, 8, wie z. B. Kanadabalsam mit den einzelnen Deckplatten 1, 4 der Flüssigkristall-Zellen optisch verbunden.To form a device with a plurality of liquid crystal stall cells, at least one support plate 5 , 9 is provided, which also consist of a glass-like material such as glass or plastic and are transparent. These carrier plates 5 , 9 are by means of an optical adhesive 7 , 8 , such as. B. Canada balm with the individual cover plates 1 , 4 of the liquid crystal cells optically connected.
An den Stellen der fehlenden Ecken 2 der Rückplatte 1 be sitzt die hintere Trägerplatte 9 Durchbrüche 10, so daß die Kontaktierungen 3 auf den Frontplatten 4, von hinten zugänglich sind.At the locations of the missing corners 2 of the back plate 1 , the rear carrier plate 9 sits openings 10 so that the contacts 3 on the front plates 4 are accessible from the rear.
Die Anzeigevorrichtung weist weiterhin Leiterplatten 11 auf, die senkrecht zur Erstreckungsebene der Flüssigkri stall-Zellen und der Trägerplatten 5, 9 angeordnet sind. An der den Flüssigkristall-Zellen zugewandten Kante der Leiterplatten 11 sind elektrisch leitende Fortsätze 12 so angebracht, daß sie durch die Durchbrüche 10 hindurchra gend mit den Kontaktflächen 3 auf den Frontplatten 4 der Flüssigkristall-Zellen kontaktierbar sind. Auf der Leiter platte 11 sind z. B. die zur Ansteuerung der FK-Zellen er forderlichen Schaltkreise und Leitungen angebracht. Sie können aus irgendeinem geeigneten isolierenden Leiterplat tenmaterial bestehen. Die Kontaktierungsfortsätze 12 kön nen aus Blech oder Drahtteilen, sie können aber auch aus metallisierten Fortsätzen der Leiterplatte bestehen.The display device also has circuit boards 11 which are arranged perpendicular to the plane of extension of the liquid crystal cells and the carrier plates 5 , 9 . At the liquid crystal cells facing edge of the circuit boards 11 are electrically conductive projections 12 are attached so that they can be contacted through the openings 10 through with the contact surfaces 3 on the front plates 4 of the liquid crystal cells. On the circuit board 11 are z. B. attached to the control of the FK cells he required circuits and lines. They can be made of any suitable insulating circuit material. The contacting extensions 12 can NEN from sheet metal or wire parts, but they can also consist of metallized extensions of the circuit board.
