Description

Die Erfindung betrifft ein Bedienmittel, zum Beispiel eine Taste oder einen Drehknopf zum Bedienen eines elektrischen Geräts, mit einem beweglichen Körper und einem Anzeigeelement, das mit dem Körper verbunden ist und mit welchem ein Symbol darstellbar ist, das die Funktion des Bedienmittels bezeichnet.The invention relates to an operating means, for example a button or a knob for operating an electrical appliance, with a movable body and a display element which is connected to the body and with which a symbol can be displayed, which designates the function of the operating means.

Aus dem Stand der Technik sind eine Vielzahl derartiger Bedienmittel bekannt. So sind beispielsweise aus Kraftfahrzeugen Bedienmittel bekannt, mit denen eine Heckscheibenheizung ein- oder ausgeschaltet werden kann oder elektrische Fensterheber für Seitenscheiben in Betrieb gesetzt werden können. Auf derartigen Bedienmitteln sind in der Regel Symbole für die Funktion des Bedienmittels angegeben. Diesen Bedienmitteln ist eine Funktion fest zugewiesen. Ferner sind insbesondere von Infotairiment-Geräten in Kraftfahrzeugen Drehknöpfe, Taster oder Schalter bekannt, die je nachdem, in welchem Modus sich das Infotainment-Gerät befindet, eine erste oder eine weitere Funktion hat. So kann beispielsweise der gleiche Drehknopf zur Auswahl eines Fahrziels in einem Navigationssystem oder zum Einstellen der Temperatur einer Klimaanlage benutzt werden, je nachdem, in welchem Modus sich das Infotainment-Gerät befindet. Die Funktion, die den Drehknopf beziehungsweise das Bedienmittel in Abhängigkeit von dem Modus zugewiesen ist, muss dem Anwender in der Regel aus der Bedienungsanleitung bekannt sein. Eventuell ist in unmittelbarer Nähe zu dem Bedienmittel in einem Bildschirm des Infotainment-Geräts ein Hinweis auf die Funktion des Bedienmittels angegeben. Diese Lösung ist jedoch nicht besonders vorteilhaft, da dann auf dem Bildschirm Platz für die Darstellung von anderen Informationen verloren geht.From the prior art, a plurality of such operating means are known. For example, from motor vehicles operating means are known with which a rear window heating can be switched on or off or electric windows can be put into operation for side windows. On such control means symbols for the function of the control means are usually indicated. These controls are assigned a function. Furthermore, knobs, buttons or switches are known in particular of Infotairiment devices in motor vehicles, which has a first or another function depending on the mode in which the infotainment device is. For example, the same knob can be used to select a destination in a navigation system or to set the temperature of an air conditioning system, depending on which mode the infotainment device is in. The function, which is assigned to the rotary knob or the operating means depending on the mode, must be known to the user usually from the operating instructions. It may be indicated in the immediate vicinity of the operating means in a screen of the infotainment device, an indication of the function of the operating means. However, this solution is not particularly advantageous because then space is lost on the screen for the presentation of other information.

Wird gar keine Information über die Funktion des Bedienmittels angezeigt und ist der Anwender auf eine Bedienungsanleitung verwiesen, ist dies ebenfalls nicht vorteilhaft und anwenderfreundlich.If no information about the function of the operating means is displayed at all and the user is referred to an operating manual, this is likewise not advantageous and user-friendly.

Hier setzt die vorliegende Erfindung an.This is where the present invention begins.

Der Erfindung liegt die Aufgabe zugrunde, ein Bedienmittel, dem eine Funktion zugewiesen ist und das mit einem Symbol für die Funktion gekennzeichnet ist, so auszugestalten, dass dem Bedienmittel verschiedene Funktionen zugewiesen werden können und gleichzeitig durch ein Symbol die zugewiesene Funktion kennzeichnet werden kann.The invention is based on the object, an operating means, which is assigned to a function and which is marked with a symbol for the function to design so that the operating means various functions can be assigned and at the same time by a symbol, the assigned function can be identified.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass dem Bedienmittel verschiedene Funktionen zuweisbar sind und dass das Anzeigemittel zum Anzeigen des darstellbaren Symbols, das die zugewiesene Funktion bezeichnet, über elektrische Anschlüsse ansteuerbar ist. Das Anzeigemittel hat somit keine statische Anzeige, wie es beispielsweise von den Bedienmitteln für die Heckscheibenheizung oder die elektrischen Fensterheber bekannt ist. Das Bedienmittel hat vielmehr eine variable Anzeige, die ein entsprechendes Symbol der dem Bedienelement jeweils zugewiesenen Funktion darstellt. Das Anzeigemittel ist dazu elektrisch ansteuerbar.This object is achieved in that the operating means various functions are assignable and that the display means for displaying the displayable symbol, which designates the assigned function, can be controlled via electrical connections. The display means thus has no static indicator, as it is known for example by the control means for the rear window heater or the power windows. Rather, the operating means has a variable display which represents a corresponding symbol of the respective function assigned to the operating element. The display means is electrically controlled for this purpose.

Ein derartiges erfindungsgemäßes Bedienmittel hat den Vorteil, dass es sehr flexibel eingesetzt werden kann. Insbesondere für die Bedienung der sogenannten Infotainment-Geräte ist dies vorteilhaft, da die Funktion des Bedienmittels mit dem Wechsel des Modus des Infotainment-Geräts gleichfalls wechseln kann und die dem Bedienmittel dann zugewiesene Funktion unmittelbar an dem Bedienmittel, nämlich in dem Anzeigeelement des Bedienmittels angezeigt wird.Such an inventive control means has the advantage that it can be used very flexibly. This is advantageous in particular for the operation of the so-called infotainment devices, since the function of the operating means can likewise change with the change of the mode of the infotainment device and the function assigned to the operating means then directly on the Operating means, namely displayed in the display element of the operating means.

Gemäß der Erfindung können die Anzeigeelemente eines erfindungsgemäßen Bedienmittels eine oder mehrere organische Leuchtdioden aufweisen, wobei mit den organischen Leuchtdioden die Symbole dargestellt werden können.According to the invention, the display elements of an operating means according to the invention may comprise one or more organic light-emitting diodes, wherein with the organic light-emitting diodes, the symbols can be displayed.

Die organischen Leuchtdioden können in einer Ebene nebeneinander angeordnet sein. Ebenso ist es denkbar, dass zusätzlich oder alternativ Leuchtdioden in einer oder mehreren weiteren Ebenen angeordnet sind.The organic light-emitting diodes can be arranged next to one another in a plane. Likewise, it is conceivable that additionally or alternatively light-emitting diodes are arranged in one or more further planes.

Die Leuchtdioden einer Ebene können in einer Matrix angeordnet sein, wobei dann mittels der Matrix die verschiedenen Symbole darstellbar sind. Je nachdem, welches Symbol dargestellt werden soll, werden die einzelnen organischen Leuchtdioden individuell angesteuert und bestromt.The light-emitting diodes of a plane can be arranged in a matrix, in which case the various symbols can be represented by means of the matrix. Depending on which symbol is to be displayed, the individual organic light-emitting diodes are individually controlled and energized.

Ebenso ist es möglich, dass einer Leuchtdiode jeweils ein Symbol zugeordnet Ist, das mittels dieser Leuchtdiode darstellbar ist. Kann eine Anode, eine Katode und/oder eine organische Schicht der organischen Leuchtdiode, die zwischen der Anode und der Katode angeordnet ist, die Kontur des darzustellenden Symbols haben. Vorteilhaft haben sowohl die Anode, die Katode als auch die organische Schicht die Kontur des Symbols, es ist aber denkbar, dass lediglich die organische Schicht die Kontur des Symbols hat oder aber nur die Anode und/oder die Katode.It is also possible that a light-emitting diode is assigned in each case a symbol which can be displayed by means of this light-emitting diode. Can an anode, a cathode and / or an organic layer of the organic light emitting diode, which is arranged between the anode and the cathode, have the contour of the symbol to be displayed. Advantageously, both the anode, the cathode and the organic layer have the contour of the symbol, but it is conceivable that only the organic layer has the contour of the symbol or only the anode and / or the cathode.

Ein Teil des Körpers eines erfindungsgemäßen Bedienmittels kann ein Trägersubstrat für eine oder mehrere Leuchtdioden bilden. Vorteilhaft sind die Leuchtdioden in einem gasdichten Material zum Beispiel Glas gekapselt, um die Lebensdauer der Leuchtdioden zu erhöhen.A part of the body of an operating means according to the invention can form a carrier substrate for one or more light-emitting diodes. Advantageous For example, the LEDs are encapsulated in a gas-tight material, such as glass, to increase the life of the LEDs.

Der Körper eines erfindungsgemäßen Bedienmittels kann zumindest teilweise aus einem metallisierbaren Kunststoff bestehen. Der Körper kann mit einer räumlich strukturierten Metallisierung versehen werden, um die elektrischen Anschlüsse für die Leuchtdioden beziehungsweise das Anzeigeelement zu erhalten.The body of an operating means according to the invention may at least partially consist of a metallizable plastic. The body can be provided with a spatially structured metallization in order to obtain the electrical connections for the LEDs or the display element.

Die Anode und/oder die Katode einer organischen Leuchtdiode eines erfindungsgemäßen Bedienmittels können aus Schichten aus Indium-Zinn-Oxid gebildet sein.The anode and / or the cathode of an organic light-emitting diode of an operating means according to the invention can be formed from layers of indium tin oxide.

Das in Fig. 1 dargestellte Bedienmittel weist einen Körper 2 aus einem metallisierbaren Kunststoff auf, der im Wesentlichen hülsenförmig ausgebildet ist. Die äußere Mantelfläche und die Außenseite des stirnseitigen Abschlusses des Körpers 2 ist mit einer Metallisierung 8 versehen, welche elektrische Anschlüsse für eine Leuchtdiode 3 bildet. Die Leuchtdiode 3 ist Teil eines Anzeigeelements das auf der Oberseite des Körpers 2 angebracht ist. Die Leuchtdiode 3 ist dabei auf der Unterseite seitlich und auf der Oberseite von Schichten eines gasdichten Materials fast vollständig eingeschlossen. Bei dem gasdichten Material kann es sich beispielsweise um Glas oder einen Kunststoff hoher Dichte oder auch eine gasdichte Lack-/Oberflächenbehandlung handeln. Durch eine transparente Kunststoffschicht 5 kann die Oberseite des gasdichten Materials 5 gegen Beschädigung, zum Beispiel Zerkratzen geschützt werden.The operating means shown in Fig. 1 comprises a body 2 made of a metallizable plastic, which is formed substantially sleeve-shaped. The outer circumferential surface and the outer side of the front-side termination of the body 2 is provided with a metallization 8, which forms electrical connections for a light-emitting diode 3. The light emitting diode 3 is part of a display element which is mounted on the top of the body 2. The light-emitting diode 3 is almost completely enclosed on the underside laterally and on the upper side of layers of a gas-tight material. The gas-tight material may be, for example, glass or a high-density plastic or else a gas-tight lacquer / surface treatment. Through a transparent plastic layer 5, the top of the gas-tight Materials 5 are protected against damage, for example, scratching.

Die Schichten aus gasdichtem Material 5 sind transparent, so dass von der Leuchtdiode 3 emittiertes Licht auf der Oberseite des Bedienmittels sichtbar ist.The layers of gas-tight material 5 are transparent, so that light emitted by the light-emitting diode 3 is visible on the upper side of the operating means.

Das Anzeigeelement kann mit seinen Leuchtdioden 3, bei denen es sich um organische Leuchtdioden (OLED) handelt, verschiedene Symbole darstellen. Je nachdem, welches Symbol dargestellt werden soll, wird das Anzeigeelement über die Metallisierungen 8 auf der Außenseite des Körpers 2 elektrisch angesteuert.The display element can represent different symbols with its light-emitting diodes 3, which are organic light-emitting diodes (OLEDs). Depending on which symbol is to be displayed, the display element is electrically controlled via the metallizations 8 on the outside of the body 2.

Zwei Beispiele für die Ausbildung der organischen Leuchtdioden 3 des Anzeigelements sind in Fig. 2a, b und Fig. 3a, b dargestellt.Two examples of the design of the organic light-emitting diodes 3 of the display element are shown in Fig. 2a, b and Fig. 3a, b.

Das Bedienmittel 1 ist beweglich in einer Schaltung eingesetzt. Zur Verbindung mit den übrigen Bestandteilen der Schaltung und zur Ansteuerung der organischen Leuchtdioden 3 des Anzeigeelements sind an einer Leiterplatte 7 Federkontakte 6 vorgesehen, die zum einen eine elektrische Verbindung zwischen den elektrischen Anschlüssen, die durch die Metallisierungen 8 gebildet werden, herstellen und zum anderen das Bedienmittel 1 mechanisch halten.The operating means 1 is movably inserted in a circuit. For connection to the other components of the circuit and for driving the organic light-emitting diodes 3 of the display element 7 spring contacts 6 are provided on a circuit board, on the one hand, an electrical connection between the electrical terminals, which are formed by the metallization 8, and on the other Hold operating means 1 mechanically.

Die in Fig. 2a und Fig. 2b dargestellte organische Leuchtdiode ist auf ein Substrat aufgebracht. Bei dem Substrat kann es sich um den . Körper 2 oder aber um das gasdichte Material 4 handeln. Zunächst ist auf das Substrat S eine Schicht aus Indium-Zinn-Oxid aufgebracht. Diese Schicht hat die Kontur einer "0". Auf diese Schicht aus Indium-Zinn-Oxid ist eine Schicht aus einem organischen Material aufgebracht, die ebenfalls die Kontur einer "0" hat. Kongurent zu den vorgenannten Schichten schließt sich eine weitere Schicht aus Indium-Zinn-Oxid an. Die beiden Schichten aus Indium-Zinn-Oxid bilden eine Anode 31 und eine Katode 33 der anorganischen Leuchtdiode 3. Die organische Schicht 32 zwischen der Anode 31 und der Katode 33 wird durch ein Bestromen der Leuchtdiode 3 zum Leuchten angeregt, wobei die Farbe des Lichtes von der Zusammensetzung der organischen Schicht 32 abhängt. Eine derartige Leuchtdiode, wie sie in den Fig. 2a und 2b dargestellt ist, kann zum Erzeugen des Symbols "0" benutzt werden. Soll eine "0" leuchten, wird die Leuchtdiode bestromt.The organic light emitting diode shown in Fig. 2a and Fig. 2b is applied to a substrate. The substrate may be the. Body 2 or act around the gas-tight material 4. First, a layer of indium tin oxide is applied to the substrate S. This layer has the contour of a "0". On this layer of indium tin oxide, a layer of an organic material is applied, which also has the contour of a "0". Kongurent to the aforementioned layers excludes another layer Indium tin oxide on. The two layers of indium-tin-oxide form an anode 31 and a cathode 33 of the inorganic light emitting diode 3. The organic layer 32 between the anode 31 and the cathode 33 is energized by energizing the light emitting diode 3, wherein the color of the light depends on the composition of the organic layer 32. Such a light-emitting diode, as shown in FIGS. 2a and 2b, can be used to generate the symbol "0". If a "0" is lit, the LED is energized.

Um weitere Symbole darstellen zu können, können in einer gleichen Ebene neben der Leuchtdiode oder in Ebenen über oder unter der Leuchtdiode weitere entsprechende Leuchtdioden, deren Konturen Symbole nachbilden, angeordnet werden. Die Gesamtheit aus solchen Leuchtdioden bildet dann das Anzeigemittel, wobei mit jeder Leuchtdiode ein Symbol erzeugt werden kann.In order to be able to display further symbols, further corresponding light-emitting diodes, the contours of which simulate symbols, can be arranged in a same plane next to the light-emitting diode or in planes above or below the light-emitting diode. The totality of such light-emitting diodes then forms the display means, wherein a symbol can be generated with each light-emitting diode.

Alternativ dazu kann die Matrix von Leuchtdioden eingesetzt werden, wie sie in Fig. 3a und 3b dargestellt ist. Eine solche Matrix von im Wesentlichen rechteckigen, in Zeilen und Spalten nebeneinander angeordneten Leuchtdioden 3 kann dazu genutzt werden, um verschiedene Symbole mit dieser Matrix darzustellen. Dazu werden die einzelnen Leuchtdioden 3 der Matrix individuell angesteuert.Alternatively, the matrix of light-emitting diodes may be used, as shown in FIGS. 3a and 3b. Such a matrix of substantially rectangular light emitting diodes 3 arranged side by side in rows and columns can be used to represent different symbols with this matrix. For this purpose, the individual light-emitting diodes 3 of the matrix are individually controlled.

Auch die Leuchtdioden 3 der Leuchtdiodenmatrix gemäß der Fig. 3a, 3b sind in drei Schichten aufgebaut und zwar aus zwei Schichten aus Indium-Zinn-Oxid und einer dazwischen liegenden Schicht aus einem organischen Material. Die Indium-Zinn-Oxid-Schichten bilden wiederum eine Anode 31 und eine Katode 33. Wird die Leuchtdiode bestromt, sendet die organische Schicht 32 Licht aus.The light-emitting diodes 3 of the light-emitting diode matrix according to FIGS. 3a, 3b are also constructed in three layers, namely two layers of indium-tin oxide and an intermediate layer of an organic material. The indium tin oxide layers in turn form an anode 31 and a cathode 33. When the LED is energized, the organic layer 32 emits light.
