Bei der Verwendung großflächiger Flüssigkristallanzeige-Tätaleaus in Glastaäüweise treten wegen des unterschiedlichen Wäfmeäusdehurtgsverhaltens häufig BefestigüngSprobleme auf. Diese Probleme machen sich besonders dann störend bemerkbar, wenn, einerseits einfache und lösbare Befestigungsmöglichkeiten gewünscht werden, und andererseits aus optischen Gründen gewisse Genauigkeiten eingehalten werden müssen. Dies ist beispielsweise der Fall» wenn solche Flüsigkristall-Anzeigeanordnungen in Glasbauweise an Lichtleiterplatten gehaltert werden sollen.When using large liquid crystal display tattoos step in glass due to the different Wäfmeäus expansion behavior often fastening problems on. These problems are particularly noticeable when, on the one hand, simple and solvable Mounting options are desired, and on the other hand certain accuracies must be maintained for optical reasons. This is the case, for example » if such liquid crystal display assemblies in glass construction to be held on light guide plates.
Der vorliegenden Neuerung liegt die Aufgabe zugrunde, bei einer Mehrfachanzeigeani>rdnung der eingangs genannten Art eine hinsichtlich der vorstehenden Probleme verbesserte Halterung anzugeben*The present innovation is based on the task of a multiple display arrangement of the type mentioned at the beginning to specify an improved bracket with regard to the above problems *
Diese Aufgabe wird gemäß der Neuerung dadurch gelöst, daß die Halterungsvorrichtung als in Öffnungen jines Trägers einsteckbarer und einrastender Vorsprung aus flexiblem Material ausgebildet und an der gläsernen Deckplatte angeklebt ist.This object is achieved according to the innovation in that the mounting device as in openings in jines carrier insertable and latching projection formed from flexible material and on the glass cover plate is glued on.
Die vorgeschlagene federnde Steckbefestigung eignet sich besonders zur Verwendung in Kraftfahrzeugen, bei welchen sehr hohe Temperaturunterschiede auftreten können« Die beschriebene Befestigungsart stellt einerseits eine gute Austauschbarkeit xicher, indem die Flüssigkristall-Anzeigezelle einfach abgenommen werden kann und gewährleistet andererseits eine dauerhafte sichere Halterung der aus Glas bestehenden Flüssigkristallzelle einer Trägerplatte, wobei die Abstandsverhältnisse zur Trägerplatte sehr genau bestimmbar sind. Letzteres ist besonders wichtig, wenn die Trägerplatte eine der Beleuchtung dienende Lichtleiterplatte ist. The proposed resilient plug-in fastening is suitable especially for use in automobiles in which very high temperature differences can occur «The type of fastening described is, on the one hand, a good one Interchangeability xicher by adding the liquid crystal display cell can be easily removed and, on the other hand, ensures that the off is permanently and securely held Glass existing liquid crystal cell of a carrier plate, the spacing ratios to the carrier plate being very precise are determinable. The latter is particularly important if the carrier plate is a light guide plate used for lighting.
UL 82/147UL 82/147
Anhand des in den Figuren i und 2 dargestellten Äusfüh rüngsbeisplela wird die Neuerung nachfolgend naher erklärt . Based on the Äusfüh shown in Figures i and 2 The innovation is explained in more detail below.
Die FIG. 1 zeigt im Ausschnitt einen Querschnitt durch eine neuerüngsgemäße Flüssigkristall-Anzeigezelle mit einer vorderen Glasplatte 6 und einer hinteren Glasplatte 1, zwischen welchen sich der Flüssigkristall 7 in bekannter Form einer dünnen Schicht befindet * Selbstverständlich können zwischen den Glasplatten noch weitere, insbesondere metallische Schichten angeordnet sein. Sie sind jedoch nicht dargestellt, weil sie für die vorliegenden Neuerung nicht von Bedeutung sind.The FIG. 1 shows a section through a new liquid crystal display cell with a front glass plate 6 and a rear glass plate 1, between which the liquid crystal 7 is located in the known form of a thin layer * Of course, further, in particular metallic layers can be arranged between the glass plates . However, they are not shown because they are not important for the present innovation.
Gemäß der Neuerung sind nun auf der hinteren Glasplatte ein oder mehrere aus Kunststoff bestehende elastische Steckverbinder 4 vorgesehen, die bevorzugt mittels einer Klebung 3 auf der Glasplatte 1 befestigt sind. Die Fortsätze 4 weisen zweckmäßig Schlitze 9 auf, wodurch die federnde Eigenschaft dieser einrastenden Steckstifte verbessert wird.According to the innovation, one or more elastic ones made of plastic are now on the rear glass plate Connectors 4 are provided, which are preferably fastened to the glass plate 1 by means of an adhesive 3. The appendages 4 expediently have slots 9, whereby the resilient property of these locking pins is improved.
Die FIG. 2 zeigt wie eine solche Flüssigkristallzelle an einer als Lichtleiter ausgebildeten Trägerplatte 2 befestigt ist. Die Trägerplatte 2 weist entsprechende Öffnungen 8 auf, in welche die rastenden Fortsätze 4 eingesteckt sind, in der Weise, daß sie eine klemmende Halte— rung bewirken und die gläserne Trägerplatte 1 der Flüssigkristallzelle an die Lichtleiterplatte 2 andrücken.The FIG. 2 shows how such a liquid crystal cell is attached to a carrier plate 2 designed as a light guide is. The carrier plate 2 has corresponding openings 8 into which the latching extensions 4 are inserted are, in such a way that they effect a clamping holding, and the glass support plate 1 of the liquid crystal cell press onto the light guide plate 2.

Zur Sicherstellüng eines gewünschten Abstandes sind Diatänzteile 5 zwischengefügt, die z. B. in Form Von Streifen oder dergleichen gegebenenfalls an die Lichtleiterplatte 2 öder an der rückwärtigen Deckplatte 1 befestigt sein können. Die bevorzugt gewählte dopßelkonische Form der Fortsätze 4 dermöglicht einerseits ein einfaches Einstecken in die Öffnungen 8 und gewährleistet andererseits ein dauerndes Andrücken der Lichtleiterplatte an den iiäger 2.In order to ensure a desired distance, diet parts 5 are inserted which, for. B. in the form of strips or the like can optionally be attached to the light guide plate 2 or to the rear cover plate 1. The preferably selected double-conical shape of the extensions 4 enables, on the one hand, simple insertion into the openings 8 and, on the other hand, ensures that the light guide plate is pressed continuously against the carrier 2.
