Diese EL-Lampe ist mit Laschen bzw.- Fahnen versehen, von welchen die eine Fahne an eine der Elektroden der EL-Lampe und die andere Fahne an die andere Elektrode der EL-Lampe angeschlossen sind. Ueber diese Fahnen bzw. Laschen wird die EL-Lampe mit elektrischer Energie versorgt.Symbols, pictures or the like can be executed. To protect these motifs, the front of the motifs is covered with a protective layer, for example made of a clear and hard resin. An electroluminescence device or an EL lamp is assigned to the side of the pane facing away from the motif. This EL lamp is provided with tabs or flags, of which one flag is connected to one of the electrodes of the EL lamp and the other flag to the other electrode of the EL lamp.

Ausserdem wird es oft verlangt, dass das Anzeigegerät eine nicht ebene Form aufweist. Oft wird nämlich verlangt, dass die Anzeige Fenster oder Vertiefungen aufweisen soll, deren Seitenflächen ebenfalls leuchten sollen. Zu diesem Zweck muss die EL- Lampe von der Frontfläche der Anzeige bis in den Bereich der dieses Fenster oder diese Vertiefung begrenzenden Seitenwände derselben gezogen werden. Unter anderem wegen dem zur Rissbildung neigenden Schichtaufbau in der vorbekannten Anzeige kann diese nur sanft gebogen werden. Der minimal erreichbare Radius eines gekrümmten Abschnittes der vorbekannten Anzeige liegt im Bereich von etwa 6mm. Dies ist beispielsweise bei Paneelgeräten inThe front area of this known device is of complex construction because of the need to use multiple layers. In addition, the display device is often required to have a non-flat shape. It is often required that the display should have windows or recesses whose side surfaces should also light up. For this purpose, the EL lamp must be pulled from the front surface of the display to the region of the side walls of this window or this recess. Among other things, due to the layer structure tending to crack in the previously known display, this can only be bent gently. The minimum achievable radius of a curved section of the known display is in the range of approximately 6 mm. This is the case, for example, with panel devices in

Fig.1 zeigt in einer Draufsicht die Frontseite einer der möglichen Ausführungen der vorliegenden dreidimensionalen Elektrolumineszenzanzeige. Diese dreidimensionale Elektrolumineszenzanzeige wird im Nachstehenden kurz auch als genannte. Fig. 2 zeigt einen vertikalen Schnitt durch das Anzeigegerät aus Fig. 1. Das Anzeigegerät weist einen im wesentlichen flächenhaften Hauptkörper 1 auf, welcher mit einer Elektrolumineszenzeinnchtung 20 versehen ist. Diese Einrichtung 20 ist im wesentlichen der Frontfläche 103 des Hauptkörpers 1 zugeordnet und sie kann gewünschte grafische Darstellungen wie Bilder, Zahlen usw. leuchtend erscheinen lassen. Dieser Hauptkörper 1 ist aus einem geeigneten Kunststoff, wobei es von Vorteil ist, wenn dieser Kunststoff sich in einem Spritzgiessprozess verarbeiten lässt. Es kann sich beispielsweise um ein Material aus der Gruppe von Acrylnitril-Butadien-Styrol- Terpolymere (ABS) handeln.1 shows a top view of the front of one of the possible versions of the present three-dimensional electroluminescent display. This three-dimensional electroluminescent display is also referred to briefly below. FIG. 2 shows a vertical section through the display device from FIG. 1. The display device has an essentially flat main body 1, which is provided with an electroluminescent device 20. This device 20 is essentially assigned to the front surface 103 of the main body 1 and it can make desired graphical representations such as images, numbers etc. appear bright. This main body 1 is made of a suitable plastic, it being advantageous if this plastic can be processed in an injection molding process. For example, it can be a material from the group of acrylonitrile-butadiene-styrene terpolymers (ABS).
In der Frontseite 103 des Hauptkörpers 1 des dargestellten Anzeigegeräts ist eine Vertiefung 101 ausgeführt, welche einen kreisförmigen Umriss hat. Diese Vertiefung 101 weist eine kreisförmig umlaufende Seitenwand 102 auf, deren Innenfläche zur Hauptebene bzw. zur Frontseite 103 des flächenhaften Hauptkörpers 1 praktisch rechtwinklig steht. Die Oberfläche dieses Abschnittes der Innenfläche 102 der Vertiefung 101 schliesst sich an die Frontfläche 103 des Hauptkörpers 1 an. Die umlaufende Seitenwand 102 steht von der Frontwand 103 des flächenhaften Hauptkörpers 1 somit nach unten bzw. rückwärts ab. Aus Fig. 2 ist ferner ersichtlich, dass sich ein Abschnitt 201 der Elektrolumineszenzeinnchtung 20 im Inneren der Hauptkörper- Vertiefung 101 fortsetzt und einen Teil der Innenfläche der die Vertiefung 101 begrenzenden Wand 102 bedeckt.In the front 103 of the main body 1 of the display device shown, a recess 101 is made, which has a circular outline. This depression 101 has a circular peripheral wall 102, the inner surface of which is practically at right angles to the main plane or to the front side 103 of the planar main body 1. The surface of this section of the inner surface 102 of the depression 101 adjoins the front surface 103 of the main body 1. The circumferential side wall 102 is from the Front wall 103 of the flat main body 1 thus downwards or backwards. From FIG. 2 it can also be seen that a section 201 of the electroluminescent device 20 continues in the interior of the main body depression 101 and covers part of the inner surface of the wall 102 delimiting the depression 101.
Die Vertiefung 101 umfasst ferner einen Boden 105, welcher sich im dargestellten Beispiel etwa auf der halben Höhe der umlaufenden Seitenwand 102 der Vertiefung 101 befindet. In der Mitte dieses Bodens 105 ist eine Oeffnung 106 ausgeführt, durch welche beispielsweise die Achse einesThe depression 101 further comprises a floor 105, which in the example shown is located approximately at half the height of the circumferential side wall 102 of the depression 101. In the middle of this bottom 105 there is an opening 106 through which, for example, the axis of a
Potentiometers (nicht dargestellt) hindurchgehen kann. An dem vorstehenden Ende der Achse des Potentiometers kann ein Betätigungsknopf angebracht sein. Die sich verbreitende Spur 107 (Fig. 1), welche praktisch parallel zur Vertiefungswand 102 verläuft, deutet die Richtung an, in welcher die gesteuerte Grosse, beispielsweise Lautstärke, ihren grösseren Wert erhält.Potentiometers (not shown) can go through. An actuation button can be attached to the protruding end of the axis of the potentiometer. The widening track 107 (FIG. 1), which runs practically parallel to the recess wall 102, indicates the direction in which the controlled variable, for example volume, receives its greater value.
In einem weiteren Bereich des Hauptkörpers 1 des Gerätes ist ein Hohlraum 7 ausgeführt, welcher sich nach hinten bzw. rückwärts öffnet. Dieser Hohlraum 7 kann eine viereckförmige Kontur haben. In diesem Fall ist dieser Hohlraum 7 durch vier Wände 43 seitlich begrenzt, welche von der Rückseite des flächenhaften Abschnittes 103 des Hauptkörpers 1 rückwärts abstehen. Der Hohlraum 7 dient zur Aufnahme einer Quelle 15 zur Speisung der Elektrolumineszenzeinnchtung 20 mit elektrischer Energie. Der Hohlraum7 liegt im in Fig. 2 gezeigten Fall unterhalb der genannten Vertiefung 101. In Fig. 2 sind auch Kontaktstifte 17 und 18 dargestellt, über welche eine Gleichspannung von beispielsweise 12 Volt der Quelle 15 zugeführt wird. Diese Kontaktstifte 17 und 18 befinden sich an der von der Elektrolumineszenzeinnchtung 20 abgewandten Seite der Quelle 15. Fig. 3 zeigt in einem vertikalen Schnitt die Struktur der Elektrolumineszenzeinnchtung 20, wobei es sich in Fig. 3 nur um einen Ab- bzw. Ausschnitt aus der Einrichtung 20 handelt, welche in Fig. 2 dargestellt ist. Die Elektrolumineszenzeinnchtung 20 umfasst einen vorderen durchsichtigen oder zumindest durchscheinenden und flächenhaften Teil 2, welcher in Fig. 3 zuoberst dargestellt ist. Die Folie 2 muss ferner die Eigenschaft haben, dass sie sich tiefziehen lässt. Kunststoffe, welche für die Herstellung solcher Folien 2 geeignet sind, sind allgemein bekannt. Stellvertretend für auch andere Materialien dieser Art kann beispielsweise eine Folie genannt werden, welche die Firma Bayer AG unter der Marke Makrofol® vertreibt. Zur Erzielung besonderer Effekte kann die Folie 2 auch mittels Mehrschichtaufbau realisiert sein.In a further area of the main body 1 of the device there is a cavity 7 which opens towards the rear or backwards. This cavity 7 can have a quadrangular contour. In this case, this cavity 7 is laterally delimited by four walls 43 which protrude rearward from the rear of the flat section 103 of the main body 1. The cavity 7 serves to receive a source 15 for supplying the electroluminescent device 20 with electrical energy. In the case shown in FIG. 2, the cavity 7 lies below the depression 101 mentioned. In FIG. 2, contact pins 17 and 18 are also shown, via which a direct voltage of, for example, 12 volts is supplied to the source 15. These contact pins 17 and 18 are located on the side of the source 15 facing away from the electroluminescent device 20. FIG. 3 shows the structure of the electroluminescent device 20 in a vertical section, wherein in FIG. 3 it is only a section of the device 20 which is shown in FIG. 2. The electroluminescent device 20 comprises a front transparent or at least translucent and flat part 2, which is shown at the top in FIG. 3. The film 2 must also have the property that it can be deep drawn. Plastics which are suitable for the production of such films 2 are generally known. A film that Bayer AG sells under the Makrofol® brand can be used to represent other materials of this type. To achieve special effects, the film 2 can also be realized by means of a multilayer structure.
Die Unter- bzw. Hinterseite der in Fig. 3 dargestellten Folie 2 ist mit einem zweidimensionalen Motiv 9 versehen. Bei diesem Motiv 9 kann es sich beispielsweise um dreidimensionale grafische Darstellungen wie Symbole, Bilder, Zahlen usw. handeln. Die Inhalte solcher Motive 9 werden durch in Abständen nebeneinander liegende, diskrete Elemente 8 sowie dazwischen liegende Fenster 81 definiert. Licht, welches durch die Fenster 81 zwischen den Motivelementen 8 durch die Folie 2 hindurchgeht, wiedergibt den Inhalt des Motivs 9. Die Motivelemente 8 erscheinen in der Schnittdarstellung von Fig. 3 als diskrete Striche, welche auf der Hinter- bzw. Rückseite der Folie 2 angebracht sind. Diese Motive 9 befinden sich somit im Inneren der Elektrolumineszenzeinnchtung 20, wo sie beispielsweise gegen Abrieb und sonstige negative Einflüsse durch die davor angeordnete Folie 2 geschützt sind.The bottom or rear side of the film 2 shown in FIG. 3 is provided with a two-dimensional motif 9. This motif 9 can be, for example, three-dimensional graphic representations such as symbols, images, numbers, etc. The contents of such motifs 9 are defined by discrete elements 8 lying next to one another at intervals and windows 81 lying between them. Light that passes through the window 81 between the motif elements 8 through the film 2 reproduces the content of the motif 9. The motif elements 8 appear in the sectional view of FIG. 3 as discrete lines, which are on the back or back of the film 2 are attached. These motifs 9 are thus located inside the electroluminescent device 20, where they are protected, for example, against abrasion and other negative influences from the film 2 arranged in front of them.
Der Hinterseite der Folie 2 und somit auch der Hinterseite des Motivs 9 ist die eigentliche Lumineszenzvorrichtung 10 zugeordnet, welche im dargestellten Fall eine Elektrolumineszenz-Vorrichtung ist. Im Nachstehenden wird diese Vorrichtung auch nur EL-Vorrichtung oder EL-Lampe 10 genannt. Die EL- Vorrichtung 10 weist zwei flächenhafte Elektroden, nämlich eine Frontelektrode 11 und eine Rückelektrode 12 auf, welche sich in einem Abstand voneinander befinden. Ein Dielektrikum 13 ist zwischen diesen Elektroden 11 und 12 angeordnet. Dieses Dielektrikum 13 ist derart, dass es leuchten kann, wenn die Betriebspannung an die Elektroden 11 und 12 der EL-Vorrichtung 10 angelegt wird. An der Rückseite der EL-Vorrichtung 10 ist eine Abdeckschicht 14 abgelagert, welche aus einem isolierenden Material ist.The actual luminescence device 10 is assigned to the back of the film 2 and thus also to the back of the motif 9, which is an electroluminescence device in the case shown. In the following this will be Device also called just EL device or EL lamp 10. The EL device 10 has two planar electrodes, namely a front electrode 11 and a rear electrode 12, which are located at a distance from one another. A dielectric 13 is arranged between these electrodes 11 and 12. This dielectric 13 is such that it can light up when the operating voltage is applied to the electrodes 11 and 12 of the EL device 10. A cover layer 14, which is made of an insulating material, is deposited on the back of the EL device 10.
Bei der Herstellung des vorliegenden Gerätes wird zunächst die Elektrolumineszenzeinnchtung 20 hergestellt. In einem ersten Herstellungsschritt wird die Folie 2 bereitgestellt. Dies bedeutet, dass die Folie 2 zunächst in ihrer unverformten, d.h. praktisch planen Form vorliegt. Diese Folie 2 dient im weiteren als Träger in der EL- Einrichtung 20, und zwar unter anderem auch als Träger für die EL-Vorrichtung 10. Die Rück- bzw. Hinterseite der Folie 2 wird mit einem oder mehreren Motiven 9 versehen, beispielsweise durch Bedrucken. Auf die Rückseite des Motivs 9 sowie auf die zwischen den Motivelementen 8 frei liegenden Bereichen der Rückseite der Folie 2 wird in einem weiteren Herstellungsschritt die erste Elektrode d.h. die Frontelektrode 11 der EL-Vorrichtung 10 angebracht. Dies kann ebenfalls in einem an sich bekannten Verfahren erfolgen. Bei der Wahl dieses Verfahrens ist darauf zu achten, dass die Frontelektrode 11 auf der Folie 2 möglichst gut haftet. Das Material der Frontelektrode 11 muss ferner nicht nur leitend sondern auch durchsichtig oder zumindest durchscheinend sein. Das Material der Frontelektrode 11 kann ein elektrisch leitendes Material auf anorganischer oder organischer Basis sein, z.B. Baytron® und/oder Polyanilin und/oder Polypyrrol, modifiziert mit hochflexiblen Bindemitteln, z.B. auf Basis PU, PMMA, PVA. Auf diese Frontelektrode 11 wird eine weitere Schicht 13 aufgetragen, welche aus dem bereits erwähnten dielektrischen Material besteht. Dieses Material kann beispielsweise aus einer Mischung von ZnS, BaTi03 und den erwähnten hochflexiblen Bindemitteln bestehen.In the manufacture of the present device, the electroluminescent device 20 is first produced. The film 2 is provided in a first production step. This means that the film 2 is initially in its undeformed, ie practically planar form. This film 2 also serves as a carrier in the EL device 20, specifically also as a carrier for the EL device 10. The rear or rear side of the film 2 is provided with one or more motifs 9, for example by printing , In a further production step, the first electrode, ie the front electrode 11 of the EL device 10, is attached to the back of the motif 9 and to the areas of the back of the film 2 which are exposed between the motif elements 8. This can also be done in a method known per se. When choosing this method, care must be taken that the front electrode 11 adheres to the film 2 as well as possible. The material of the front electrode 11 must not only be conductive but also transparent or at least translucent. The material of the front electrode 11 can be an electrically conductive material on an inorganic or organic basis, for example Baytron® and / or polyaniline and / or polypyrrole, modified with highly flexible binders, for example based on PU, PMMA, PVA. A further layer 13, which consists of the dielectric material already mentioned, is applied to this front electrode 11. This material can consist, for example, of a mixture of ZnS, BaTi0 3 and the highly flexible binders mentioned.
Auf der freien, d.h. hinteren Oberfläche dieser dielektrischen Schicht 13 wird schliesslich die dritte Schicht abgelagert, welche die Rückelektrode 12 darstellt. Das Material dieser Rückelektrode 12 kann ein elektrisch leitendes Material auf anorganischer oder organischer Basis sein, z.B. Baytron® und/oder Polyanilin und/oder Polypyrrol, modifiziert mit hochflexiblen Bindemitteln, z.B. auf Basis PU, PMMA, PVA. Zwecks Verbesserung der elektrischen Leitfähigkeit kann das Material dieser Schicht 12 mit Silber oder Kohlenstoff versetzt und/oder mit einer Lage aus diesen Materialien ergänzt sein.On the free, i.e. Finally, the third layer, which represents the rear electrode 12, is deposited on the rear surface of this dielectric layer 13. The material of this back electrode 12 can be an electrically conductive material on an inorganic or organic basis, e.g. Baytron® and / or polyaniline and / or polypyrrole, modified with highly flexible binders, e.g. based on PU, PMMA, PVA. In order to improve the electrical conductivity, the material of this layer 12 can be mixed with silver or carbon and / or supplemented with a layer of these materials.
Schliesslich wird die Abdeckschicht 14 auf die Hinterseite der EL-Vorrichtung 10 aufgetragen.Finally, the cover layer 14 is applied to the rear of the EL device 10.
Wegen der nachfolgenden Behandlung dieser Elektrolumineszenzeinnchtung 20 ist es von ausserordentlicher Wichtigkeit, dass auch die einzelnen Schichten der Elektrolumineszenzvornchtung 10 so gut wie möglich aufeinander haften. Die vorstehend beschriebene Zusammensetzung der einzelnen Schichten 11 bis 14 gewährleistet nicht nur die unverrückbare Haftung der genannten Schichten aufeinander sondern auch eine bislang nicht erreichbare Dehnfähigkeit der genannten Schichten. Die Elektrolumineszenzeinnchtung 20, in welcher die EL-Vorrichtung 10 auf der Folie 2 fest haftet, wird jetzt tiefgezogen, geprägt, hohlgeprägt, massivgeprägt oder dgl. (Fig. 2 und 4). Die so umgeformte Elektrolumineszenzeinnchtung 20 kann unter anderem auch Erhebungen 3 und Vertiefungen 4 (Fig. 2) aufweisen. Die Dicke dieser Abschnitte 3, und 4 der EL-Einrichtung 20 ist im wesentlichen dieselbe wie die Dicke der nicht verformten Abschnitte 5 (Fig. 2) der Elektrolumineszenzeinnchtung 20.Because of the subsequent treatment of this electroluminescent device 20, it is extremely important that the individual layers of the electroluminescent device 10 adhere to one another as well as possible. The composition of the individual layers 11 to 14 described above ensures not only the immovable adhesion of the layers mentioned to one another but also a previously unattainable elasticity of the layers mentioned. The electroluminescent device 20 in which the EL device 10 adheres firmly to the film 2 is now deep-drawn, embossed, hollow-embossed, solid-embossed or the like (FIGS. 2 and 4). The thus formed electroluminescent device 20 can also have elevations 3 and depressions 4 (FIG. 2). The thickness of these sections 3 and 4 of the EL device 20 is substantially the same as the thickness of the undeformed sections 5 (FIG. 2) of the electroluminescent device 20.
Während der genannten Verformung der Elektrolumineszenzeinnchtung 20 können sogar Durchbrüche in der Elektrolumineszenzeinnchtung 20 erzielt werden, ohne dass die Funktionstüchtigkeit der ElektrolumineszenzeinnchtungDuring the aforementioned deformation of the electroluminescent device 20, breakthroughs can even be achieved in the electroluminescent device 20 without the functionality of the electroluminescent device
20 darunter leidet. Fig. 4 zeigt einen der Bereiche der EL-Einrichtung 20 in einem vertikalen Schnitt, welcher einen solchen Durchbruch 110 aufweist.20 suffers from it. FIG. 4 shows one of the areas of the EL device 20 in a vertical section, which has such an opening 110.
Dieser Durchbruch 110 hat eine kreisförmige Kontur und an diese Kontur schliesst sich ein Fortsatz 201 an, welcher die Form eines kurzen Rohrstückes hat. Die Wand 111 bzw. die Wände dieses Fortsatzes 201 stehen unter einem praktisch rechten Winkel Alpha zur Stirnfläche 29 derThis opening 110 has a circular contour and an extension 201 adjoins this contour, which has the shape of a short piece of pipe. The wall 111 or the walls of this extension 201 are at a practically right angle alpha to the end face 29 of the
Elektrolumineszenzeinnchtung 20.Electroluminescent device 20.
Der Fortsatz 201 ist aus jenem Abschnitt des Materials der EL-Einrichtung 20 gebildet worden, welches sich innerhalb der genannten kreisförmigen Kontur des Durchbruches 110 befand und welches durch das Tiefziehen in den Durchbruch 110 hineingezogen wurde. Zwischen dem Fortsatz 201 und dem planen, den Durchbruch 110 umgebenden Abschnitt der EL-Einrichtung 20 befindet sich ein gekrümmter Uebergangsabschnitt 6 (Fig. 4 und 10) der EL- Einrichtung 20. Der Krümmungsradius dieses Uebergangsabschnittes 6, welcher sich von der Stirnfläche 29 der Elektrolumineszenzeinnchtung 20 bis zur Seitenfläche 111 des genannten Fortsatzes 201 erstreckt, kann sehr klein gehalten werden. Dank unter anderem der unverrückbaren Haftung der Schichten 2, 9 und 11 bis 14 aufeinander sowie wegen der bislang nicht erreichbaren Dehnfähigkeit der genannten Schichten 2, 9 und 11 bis 14, kann der Krümmungsradius des Uebergangsabschnittes 6 weniger als 1mm betragen, ohne dass Risse in den Schichten der EL-Einrichtung 20 entstehen. Zudem kann die Wand 111 des Fortsatzes 201 zur Stirnfläche 29 der Elektrolumineszenzeinnchtung 20 unter einem Winkel Alpha von praktisch 90 Grad, d.h. praktisch senkrecht stehen.The extension 201 has been formed from that portion of the material of the EL device 20 which was located within the circular contour of the opening 110 and which was drawn into the opening 110 by deep drawing. Between the extension 201 and the planar section of the EL device 20 surrounding the opening 110 there is a curved transition section 6 (FIGS. 4 and 10) of the EL device 20. The radius of curvature of this transition section 6, which extends from the end face 29 of the Electroluminescent device 20 extends to the side surface 111 of the extension 201 mentioned, can be kept very small. Thanks among other things to the immovable adhesion of layers 2, 9 and 11 to 14 to each other and because of the so far not achievable extensibility of the layers 2, 9 and 11 to 14 mentioned, the radius of curvature of the transition section 6 can be less than 1 mm, without cracks occurring in the layers of the EL device 20. In addition, the wall 111 of the extension 201 to the end face 29 of the electroluminescent device 20 can be at an angle alpha of practically 90 degrees, ie practically perpendicular.
Das Dielektrikum 13 stellt im Vergleich mit den Elektroden 11 und 12 der EL- Einrichtung 20 eine verhältnismässig dicke Schicht dar.The dielectric 13 represents a relatively thick layer in comparison with the electrodes 11 and 12 of the EL device 20.
Diese dielektrische Schicht 13 kann aus mehreren aufeinander liegenden Lagen bestehen. In Fig. 10 ist der betreffende Abschnitt des Uebergangsbereiches 6 der EL-Einrichtung 20 stark vergrössert dargestellt.This dielectric layer 13 can consist of several layers lying one on top of the other. The relevant section of the transition area 6 of the EL device 20 is shown in a greatly enlarged manner in FIG. 10.
Die in Fig. 10 dargestellte Elektrolumineszenzeinnchtung 20 weist eineThe electroluminescent device 20 shown in FIG. 10 has one
Dielektrikumschicht 13 auf, welche aus drei Lagen besteht 131 , 132 und 133. Diese Lagen 131 , 132 und 133 können aus einem der vorstehend genannten dielektrischen Matehale oder sie können aus unterschiedlichen dielektrischen Materialien sein. Während der Herstellung der EL-Einrichtung 20 werden die Lagen 131 , 132 und 133 einzeln und nacheinander auf die Frontelektrode 11 bzw. auf die jeweils vorher aufgetragene Lage aufgetragen. Dielectric layer 13, which consists of three layers 131, 132 and 133. These layers 131, 132 and 133 can be made of one of the above-mentioned dielectric materials or they can be made of different dielectric materials. During the manufacture of the EL device 20, the layers 131, 132 and 133 are applied individually and in succession to the front electrode 11 or to the layer previously applied in each case.
Die unten liegende Kante 115 des Fortsatzes 201 steht frei. Wegen der bereits erwähnten ausserordentlichen Haftung der einzelnen Schichten der Elektrolumineszenzeinnchtung 20 aufeinander sowie deren hohen Dehnfähigkeit behält die Elektrolumineszenzeinnchtung 20 ihre ursprüngliche bzw. im Bereich der Frontfläche 103 vorhandene Struktur auch im tiefgezogenen Abschnitt 201. Folglich kann auch die zylinderförmige Innenfläche 111 dieses Fortsatzes 201 das durch die Elektrolumineszenzvornchtung 10 erzeugte Licht abstrahlen.The lower edge 115 of the extension 201 is free. Because of the already mentioned extraordinary adhesion of the individual layers of the electroluminescent device 20 to one another and their high elasticity, the electroluminescent device 20 retains its original structure or structure present in the area of the front surface 103 even in the deep-drawn section 201 the electroluminescent device 10 emit light generated.
Bei dieser Ausführung der vorliegenden Einrichtung ist es möglich, die freie Endpartie 115 des Fortsatzes 201 so zu gestalten, dass die Elektroden 11 und 12 nicht bis zur Schnittkante 115 reichen. Sowohl die Frontelektrode 11 als auch die Rückelektrode 12 enden in einem Abstand von der Schnittkante 115. Hingegen sowohl die Abdeckschicht 14 als auch die Dielektrikumschicht 13 reichen bis in den Bereich der Schnittkante 115. Dies bringt unter anderem auch einen sicherheitsrelevanten Vorteil mit sich, nämlich, dass die Elektroden 11 und 12, welche an einem verhältnismässig hohen elektrischen Potential liegen nicht berührt werden können, weil deren freien Kanten zumindest durch das isolierende Material der Abdeckschicht 14 zugedeckt sind. Ausserdem verhindern die bis zur Schnittkante 115 reichenden Schichten 13 und 14 ein allfälliges Eindringen von Feuchtigkeit in die Räume zwischen den einzelnen Schichten der Elektrolumineszenzeinnchtung 20.In this embodiment of the present device, it is possible to design the free end portion 115 of the extension 201 in such a way that the electrodes 11 and 12 do not reach the cutting edge 115. Both the front electrode 11 and the rear electrode 12 end at a distance from the cut edge 115. On the other hand, both the cover layer 14 and the dielectric layer 13 extend into the area of the cut edge 115. This also brings with it a safety-relevant advantage, namely, that the electrodes 11 and 12, which are at a relatively high electrical potential, cannot be touched because their free edges are at least covered by the insulating material of the covering layer 14. In addition, the layers 13 and 14 reaching to the cutting edge 115 prevent any penetration of moisture into the spaces between the individual layers of the electroluminescent device 20.
Nach dem Tiefziehen wird der Hauptkörper 1 der Rückseite der Elektrolumineszenzeinnchtung 20 zugeordnet. Dies kann beispielsweise durch Hinterspritzen der Elektrolumineszenzeinnchtung 20 mit einem dazu geeigneten Material. Einige der dazu geeigneten Materialien sind vorstehende bereit genannt worden. Fig. 5 zeigt in einem vertikalen Schnitt jenen Ausschnitt aus dem Gerät gemäss Fig. 2, in welchem sich die Vertiefung befindet, und zwar samt dem betreffenden Abschnitt des Hauptkörpers 1 , in welchem der rohrstückförmige Fortsatz 201 liegt. Es versteht sich, dass sich das Material des Hauptteiles 1 während dem Hinterspritzen an die Aussenseite des Fortsatzes 115 legte.After the deep-drawing, the main body 1 is assigned to the rear of the electroluminescent device 20. This can be done, for example, by injecting the electroluminescent device 20 with a suitable material. Some of the suitable materials have already been mentioned above. FIG. 5 shows, in a vertical section, that section of the device according to FIG. 2 in which the depression is located, namely together with the relevant section of the main body 1 in which the tubular extension 201 is located. It goes without saying that the material of the main part 1 lay against the outside of the extension 115 during the back injection.
Fig. 6 zeigt ein Werkzeug 30, in welchem das in Fig. 1 bzw. 2 gezeigte Gerät durch Hinterspritzen der Elektrolumineszenzeinnchtung 20 hergestellt werden kann. Dieses Werkzeug 30 hat einen Unterteil 31 und einen Oberteil 32, welche aufeinander passen und welche in einer an sich bekannten Weise zueinander beispielsweise schwenkbar oder geradlinig verschiebbar geführt werden, wenn dieses Werkzeug 30 geöffnet und geschlossen werden soll. Im unteren Formteil 31 befindet sich ein erster Gesenkeinsatz 33 und im oberen Formteil 32 befindet sich ein zweiter Gesenkeinsatz 34. Der Verlauf der Oberfläche der Höhlung im jeweiligen Gesenkeinsatz 33 bzw. 34 entspricht dem Verlauf der gewünschten Oberfläche jener Seite des Anzeigegeräts, welche durch den betreffenden Gesenkeinsatz 33 bzw. 34 geformt werden soll. Im unterenFIG. 6 shows a tool 30 in which the device shown in FIGS. 1 and 2 can be produced by back-injection of the electroluminescent device 20. This tool 30 has a lower part 31 and an upper part 32, which fit one another and which can be guided in a manner known per se, for example pivotably or in a straight line, when this tool 30 is to be opened and closed. In the lower mold part 31 there is a first die insert 33 and in the upper mold part 32 there is a second die insert 34. The course of the surface of the cavity in the respective die insert 33 or 34 corresponds to the course of the desired surface of that side of the display device which is affected by the relevant one Die insert 33 or 34 is to be shaped. At the bottom
Werkzeugteil 31 sind Kanäle 37 ausgeführt, durch welche das Material, welches in den Hohlraum des Werkzeuges gelangen soll, in das Werkzeug 30 eingeführt und in diesem verteilt wird.Tool part 31 are designed channels 37 through which the material which is to get into the cavity of the tool is introduced into the tool 30 and distributed therein.
Im Zusammenhang mit Fig. 2 ist der Verlauf der Oberflächen der Folie 2 bereits beschrieben worden. Der Verlauf der Oberfläche der Höhlung im oberen Gesenkeinsatz 34 muss dem Verlauf der äusseren Oberfläche bzw. der Vorderfläche der Folie 2 entsprechen. Entsprechendes gilt für die Form der Oberfläche der Höhlung im unteren Gesenkeinsatz 33. Hier ist vor allen auf zwei sich in einem Abstand voneinander befindlichen Vorsprünge 38 und 39 hinzuweisen, welche aus der Oberfläche der Höhlung im unteren Gesenkeinsatz 33 hervorstehen. Die Höhe dieser Vorsprünge 38 und 39 ist derart gewählt, dass die Stirnfläche dieser Vorsprünge 38 und 39 während dem Hinterspritzprozess auf der rückwärtigen Seite der EL-Einrichtung 20 aufliegen. Dadurch bleiben zwei Kanäle 38 und 39 in diesem Bereich des Hauptkörpers 1 frei, deren Verwendung im nachstehend beschrieben istThe course of the surfaces of the film 2 has already been described in connection with FIG. 2. The course of the surface of the cavity in the upper die insert 34 must correspond to the course of the outer surface or the front surface of the film 2. The same applies to the shape of the surface of the cavity in the lower die insert 33. Here it is important to point out two projections 38 and 39 which are at a distance from one another and which protrude from the surface of the cavity in the lower die insert 33. The height of these projections 38 and 39 is selected such that the end face of these projections 38 and 39 lie on the rear side of the EL device 20 during the back injection process. This leaves two channels 38 and 39 free in this area of the main body 1, the use of which is described below
Zur bereits genannten Speisequelle 15 gehört ein elektronischer Teil nämlich ein Wandler 16, welcher eine verhältnismässig niedrige Gleichspannung von beispielsweise 12 V in eine für den Betrieb der EL-Vorrichtung 10 erforderliche und verhältnismässig hohe Wechselspannung umwandelt. Dieser Umformer 16 ist im dargestellten Fall im bereits genannten Hohlraum 7 des Hauptkörpers 1 eingelassen und mit Hilfe beispielsweise einer Spannhülse 44 an Ort und Stelle gehalten. Sonst kann der Wandler 16 im Hauptkörper 1 des Anzeigegeräts nur teilweise eingelassen sein oder dieser kann als eine vom Anzeigegerät unabhängige Einheit vorliegen.An electronic part belongs to the aforementioned feed source 15, namely a converter 16, which converts a relatively low DC voltage of, for example, 12 V into a relatively high AC voltage required for the operation of the EL device 10. In the case shown, this converter 16 is embedded in the cavity 7 of the main body 1 already mentioned and is held in place with the aid of, for example, an adapter sleeve 44. Otherwise, the converter 16 can be only partially embedded in the main body 1 of the display device or it can be present as a unit that is independent of the display device.
Von der Rückseite des Wandlers 16 stehen die ebenfalls bereits erwähnten Kontaktstifte 17 und 18 ab, welche aus dem Material des Hauptkörpers 1 teilweise ragen können. An die aus dem Hauptkörper 1 ragenden Abschnitte der Pins 17 und 18 können die Pole einer Gleichspannungsquelle, z.B. eines Akkumulators (nicht dargestellt) angeschlossen sein. Die für den Betrieb der Elektrolumineszenzeinnchtung 20 erforderliche Spannung kann 110V/ 400Hz betragen und sie wird über Kontaktvorrichtungen 21 und 22 an die Elektrolumineszenzeinnchtung 20 angeschlossen. (Fig. 7, 8 und 9)The contact pins 17 and 18, which have also already been mentioned, protrude from the rear of the converter 16 and can partially protrude from the material of the main body 1. The poles of a DC voltage source, e.g. an accumulator (not shown) may be connected. The voltage required for the operation of the electroluminescent device 20 can be 110V / 400Hz and it is connected to the electroluminescent device 20 via contact devices 21 and 22. (Figs. 7, 8 and 9)
Die erste dieser Kontaktvorrichtungen 21 kontaktiert die Rückelektrode 12 der EL-Lampe 10. Die zweite der Kontaktvorrichtungen 22 kontaktiert die Frontelektrode 11 der EL-Lampe 10. Die erste dieser Kontaktvorrichtungen 21 liegt im ersten Kanal 38 des Hauptteiles 1. Die zweite der Kontaktvorrichtungen 22 liegt im zweiten Kanal 39 des Hauptteiles 1. Die jeweiligen Kontaktvorrichtung 21 bzw. 22 umfasst eine Feder, im dargestellten Fall eine Schraubenfeder 210 bzw. 220. Die Federn 210 und 220 liegen einerends an einer entsprechenden elektrisch leitenden Ausgangsstelle 211 bzw. 221 des Wandlers 16 auf. Das andere Ende der Feder 210 der ersten Kontaktvorrichtung 21 liegt auf dem Material der Rückelektrode 12 der EL- Vorrichtung 10 auf. Das andere Ende der Feder 220 der zweiten Kontaktvorrichtung 22 liegt auf dem Material der Frontelektrode 11 der EL- Vorrichtung 10 auf.The first of these contact devices 21 contacts the back electrode 12 of the EL lamp 10. The second of the contact devices 22 contacts the front electrode 11 of the EL lamp 10. The first of these contact devices 21 lies in the first channel 38 of the main part 1. The second of the contact devices 22 lies in the second channel 39 of the main part 1. The respective contact device 21 or 22 comprises a spring, in the illustrated case a coil spring 210 or 220. The springs 210 and 220 are located at one end at a corresponding electrically conductive starting point 211 or 221 of the Converter 16 on. The other end of the spring 210 of the first contact device 21 lies on the material of the back electrode 12 of the EL device 10. The other end of the spring 220 of the second contact device 22 lies on the material of the front electrode 11 of the EL device 10.
Die in Fig. 7 dargestellte Anordnung betrifft den Fall, wenn die Kontaktvorrichtungen 21 und 22 einem Bereich der EL-Lampe 10 dieser zugeordnet sind, wo die Elektroden 11 und 12 der EL-Lampe 10 nicht übereinander liegen. Dies kann beispielsweise in einer Randpartie 42 der EL- Lampe 10 der Fall sein, welche in Fig. 7 abgebildet ist. In dieser Randpartie 42 liegt die Randkante der Rückelektrode 12 in einem grösseren Abstand von der Kante 42 der EL-Lampe 10 als die Randkante der Frontelektrode 11. Bis zur Kante 42 der EL-Lampe 10 reicht nur die Abdeckelektrode 14, welche aus einem elektrisch isolierenden Material ist.The arrangement shown in FIG. 7 relates to the case when the contact devices 21 and 22 are assigned to a region of the EL lamp 10 where the electrodes 11 and 12 of the EL lamp 10 are not superimposed. This can be the case, for example, in an edge area 42 of the EL lamp 10, which is shown in FIG. 7. In this edge area 42, the edge of the rear electrode 12 lies at a greater distance from the edge 42 of the EL lamp 10 than the edge of the front electrode 11. Only the cover electrode 14, which consists of an electrically insulating material, extends to the edge 42 of the EL lamp 10 Material is.
Wenn die Elektroden 11 und 12 der EL-Lampe 10 durch die Speisequelle 15 in einem innenliegenden Bereich der EL-Lampe 10 kontaktiert werden sollen, in welchem die Elektroden 11 und 12 übereinander liegen, dann muss in der Schicht der Rückelektrode 12 eine Oeffnung 43 für den Durchgang jenerIf the electrodes 11 and 12 of the EL lamp 10 are to be contacted by the supply source 15 in an inner region of the EL lamp 10, in which the electrodes 11 and 12 lie one above the other, then an opening 43 must be made in the layer of the back electrode 12 the passage of those
Kontaktvorrichtung 22 ausgeführt sein, welche die Frontelektrode 11 berühren soll. Die Oeffnung 43 in der Rückelektrode 12 muss so gross sein, dass diese Kontaktvorrichtung 22 die Rückelektrode 12 nicht berührt. Hierzu genügt es normalerweise, wenn die Oeffnung 43 in der Rückelektrode 12 ausreichend gross ist, um zu verhindern, dass die Feder 220 der Kontaktvorrichtung 22 für die Frontelektrode 11 die Rückelektrode 12 berührt.Contact device 22 may be executed, which should touch the front electrode 11. The opening 43 in the back electrode 12 must be so large that this contact device 22 does not touch the back electrode 12. To this end, it is normally sufficient if the opening 43 in the rear electrode 12 is sufficiently large to prevent the spring 220 of the contact device 22 for the front electrode 11 from touching the rear electrode 12.
Nachdem der Hauptteil 1 des Anzeigegerätes durch Hinterspritzen der Elektrolumineszenzeinnchtung 20 hergestellt worden ist, haftet die Elektrolumineszenzeinnchtung 20 auf dem Hauptkörper 1. Die genannte Speisequelle 15 wird nun in den Hohlraum 7 des Hauptkörpers 1 eingesetzt, und zwar derart, dass die Kontaktvorrichtungen 21 und 22 in den Kanälen 38 und 39 des Hauptkörpers 1 liegen. Danach wird die Speisequelle 16 in den Hohlraum 7 so weit eingedrückt, bis die Frontenden der Feder 210 und 220 auf der leitenden Schicht der betreffenden Elektrode 12 bzw. 13 der Elektrolumineszenzvornchtung 10 aufliegen. Hiernach muss man die Speisequelle 15 in dieser Lage fixieren, was beispielsweise durch einen geeigneten Klebstoff oder dgl. geschehen kann.After the main part 1 of the display device has been produced by back-injection of the electroluminescent device 20, it is liable Electroluminescent device 20 on the main body 1. The feed source 15 is now inserted into the cavity 7 of the main body 1 in such a way that the contact devices 21 and 22 are located in the channels 38 and 39 of the main body 1. The feed source 16 is then pressed into the cavity 7 until the front ends of the springs 210 and 220 rest on the conductive layer of the relevant electrode 12 or 13 of the electroluminescent device 10. After this, the feed source 15 must be fixed in this position, which can be done, for example, with a suitable adhesive or the like.
Fig. 8 zeigt eine weitere Möglichkeit dafür, wie die Speisequelle 15 dem Hauptkörper 1 zugeordnet sein kann. In diesem Fall ist der wesentliche Teil der Speisequelle 15 im Hauptkörper 1 eingelassen. Um diese Anordnung herzustellen wird ein flächenhaftes Zwischenstück 46 verwendet. In diesem Zwischenstück 46 gibt es Kanäle 48 und 49, welche sich senkrecht zu den Hauptflächen des Zwischenstückes 46 erstrecken. Eine der Grossflächen des Zwischenstückes 46 wird auf der Abdeckschicht 14 der EL-Lampe 10 aufgeklebt. Danach wird die Speisequelle 15 dem Zwischenstück 46 so zugeordnet, dass die jeweilige Feder 38 bzw. 39 der Speisequelle 15 durch einen der Kanäle 48 bzw. 49 so hindurchgeht, dass ihr Frontende auf der betreffenden Elektrode 11 bzw. 12 der EL-Lampe 10 aufliegt. Auf die von der EL-Lampe 10 abgewandte Grossfläche des Zwischenstückes 46 wird die Vorderseite des Wandlers 16 aufgeklebt. Das so vorbereitete Halbzeug kann in die Form 30 gelegt und mit dem Material des Hauptkörpers 1 hinterspritzt werden. Der untere Teil 31 des Werkzeuges 30 ist in diesem Fall so geformt, dass sich das Material des Hauptkörpers 1 auch hinter dem Wandler 16 befinden und dass nur Abschnitte der Pins 17 und 18 aus diesem Material des Hauptkörpers 1 ragen, an welche die bereits erwähnte Gleichspannung angelegt werden kann. Das Anzeigegerät umfasst den Hauptkörper 1 und die EL-Einrichtung 20. Diese Elektrolumineszenzeinrichtung 20 besteht aus der Folie 2 und der Elektrolumineszenzvorrichtung 10, welche miteinander ein Ganzes bilden. Die der Elektrolumineszenzvorrichtung 10 zugewandte Fläche der Folie 2 ist mit anzuzeigenden Motiven 9 versehen. Die Elektrolumineszenzvorrichtung 10 umfasst die Frontelektrode 11 und die Rückelektrode 12, zwischen welchen sich das Dielektrikum 13 befindet. Die Frontelektrode 11 ist der das Motiv 9 wiedergebenden Schicht zugeordnet und mit dieser einstückig. Innerhalb der Fläche der Elektrolumineszenzeinrichtung 20 ist die Speisequelle 15 angeordnet, welche die Elektroden 11 und12 der Elektrolumineszenzeinrichtung 20 kontaktiert. FIG. 8 shows a further possibility of how the feed source 15 can be assigned to the main body 1. In this case, the essential part of the feed source 15 is embedded in the main body 1. In order to produce this arrangement, a flat intermediate piece 46 is used. In this intermediate piece 46 there are channels 48 and 49 which extend perpendicular to the main surfaces of the intermediate piece 46. One of the large areas of the intermediate piece 46 is glued onto the cover layer 14 of the EL lamp 10. Thereafter, the feed source 15 is assigned to the intermediate piece 46 in such a way that the respective spring 38 or 39 of the feed source 15 passes through one of the channels 48 or 49 such that its front end rests on the relevant electrode 11 or 12 of the EL lamp 10 , The front of the transducer 16 is glued onto the large surface of the intermediate piece 46 facing away from the EL lamp 10. The semi-finished product thus prepared can be placed in the mold 30 and back-injected with the material of the main body 1. In this case, the lower part 31 of the tool 30 is shaped in such a way that the material of the main body 1 is also located behind the transducer 16 and that only portions of the pins 17 and 18 made of this material of the main body 1 protrude to which the DC voltage already mentioned can be created. The display device comprises the main body 1 and the EL device 20. This electroluminescent device 20 consists of the film 2 and the electroluminescent device 10, which together form a whole. The surface of the film 2 facing the electroluminescent device 10 is provided with motifs 9 to be displayed. The electroluminescent device 10 comprises the front electrode 11 and the rear electrode 12, between which the dielectric 13 is located. The front electrode 11 is assigned to the layer representing the motif 9 and is integral with it. Disposed within the surface of the electroluminescent device 20 is the feed source 15, which contacts the electrodes 11 and 12 of the electroluminescent device 20.
