Description
Die
Erfindung betrifft ein Anzeigeelement mit mindestens einer strahlungserzeugenden OLED-Schicht,
die auf einem transparenten Trägersubstrat angeordnet ist.
Ein derartiges Anzeigeelement ist beispielsweise aus der
Der Begriff OLED (Kurzform für „organic light-emitting diode" oder „organic light-emitting device") bezeichnet ein als Dünnfilm ausgebildetes, leuchtendes Bauelement aus organischen, halbleitenden Materialien. OLED finden Anwendungen als relativ großflächige Leuchtelemente oder auch als Displays für Digitalkameras oder Mobiltelefone.Of the Term OLED (short for "organic light-emitting diode "or" organic light-emitting device ") a trained as a thin film, luminous component made of organic, semiconducting materials. OLED find applications as a relatively large-area lighting elements or as displays for digital cameras or mobile phones.
Es stellte sich die Aufgabe, ein Anzeigeelement zu schaffen, welches die Möglichkeiten der Symboldarstellung erweitert bzw. völlig neue Darstellungsformen ermöglicht.It the task was to create a display element which expanded the possibilities of symbol representation allows completely new forms of presentation.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass mehrere OLED-Schichten, durch jeweils ein transparentes Trägersubstrat voneinander getrennt, übereinander angeordnet sind.These The object is achieved according to the invention that multiple OLED layers, each by a transparent carrier substrate separated from each other, are arranged one above the other.
Durch die mittels der Trägersubstrate zwischen den einzelnen OLED-Schichten jeweils realisierten Abstände wird eine reale Tiefe erzeugt, durch die ein Symbol aus verschiedenen Perspektiven betrachtet werden kann.By the means of the carrier substrates between the individual OLED layers each realized spacing becomes one real depth generated by a symbol from different perspectives can be considered.
Da sowohl die OLED-Schichten als auch die Trägersubstrate transparent ausgebildet sind, also jeweils nur wenig absorbierend wirken, scheinen die Darstellungen der unteren OLED-Schichten durch die darüber liegenden OLED-Schichten hindurch, so dass die Darstellungen aller OLED-Schichten bei Ansicht des Anzeigeelements, und zwar sowohl von oben als auch aus einer seitlichen Blickrichtung, gut erkennbar sind.There both the OLED layers and the carrier substrates are transparent, so in each case little absorbing act, the representations of the lower OLED layers through the overlying OLED layers, so that the Representations of all OLED layers when viewing the display element, both from above and from a lateral direction, are clearly recognizable.
Um die dennoch unvermeidlich auftretenden Absorptionsverluste auszugleichen, die zudem für die einzelnen OLED-Schichten unterschiedlich sind, ist es vorteilhaft, wenn die Helligkeit jeder OLED-Schicht durch eine Ansteuervorrichtung separat vorgegeben werden kann.Around compensate for the inevitable absorption losses, which also differs for the individual OLED layers It is beneficial if the brightness of each OLED layer can be specified separately by a drive device.
Das erfindungsgemäße Anzeigeelement kann, abhängig von der vorgesehenen Anwendung, einen mehr oder weniger komplexen Aufbau aufweisen. Im einfachsten Fall weist jede OLED-Schicht eine vorgegebene Form oder mehrere einzelne Bereiche auf, die durch eine Ansteuerung zum Leuchten angeregt werden können. Solche relativ einfach ausgeführten Anzeigeelemente sind, etwa im Vergleich mit Matrix-Displays, besonders kostengünstig herstellbar.The Display element according to the invention can, depending from the intended application, a more or less complex Have structure. In the simplest case, each OLED layer has one given shape or several individual areas, by a Control can be excited to glow. Such relatively simple display elements are, for example Compared with matrix displays, particularly cost-effective produced.
Vorteilhaft ist, wenn die OLED-Schichten derart ausgebildet sind, dass die Form und/oder die Farbe von dargestellten Symbolen und Objekten verändert werden kann, so dass farbliche und kinetische Animationen möglich werden. Auch diesbezüglich ist es vorteilhaft, wenn die einzelnen OLED-Schichten separat angesteuert werden können.Advantageous is when the OLED layers are formed such that the shape and / or changes the color of displayed symbols and objects can be, allowing colored and kinetic animations become. Also in this regard, it is advantageous if the individual OLED layers can be controlled separately.
Besonders komplex ausgestaltete Anzeigeelemente können in jeder OLED-Schicht ein vollständiges hochauflösendes Display ausbilden, so dass durch die Stapelung von mehreren OLED-Schichten frei programmierbare Symbole oder gegenständliche Objekte dreidimensional und nahezu fotorealistisch darstellbar sind. Darüber hinaus sind dreidimensionale videoartige Animationen realisierbar.Especially Complex display elements can be used in any OLED layer form a complete high-resolution display, so that by the stacking of several OLED layers freely programmable Symbols or representational objects three-dimensional and are almost photorealistic representable. Furthermore Three-dimensional video-like animations are possible.
Eine bevorzugte Anwendung des erfindungsgemäßen Anzeigeelements liegt in der Verwendung als Display in einem Kraftfahrzeug und zwar insbesondere im Zusammenhang mit den im Kraftfahrzeug vorhandenen Bedienelementen.A preferred application of the display element according to the invention is in use as a display in a motor vehicle and that in particular in connection with the existing in the motor vehicle Controls.
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung gehen aus den abhängigen Ansprüchen und der nachfolgenden Beschreibung eines Ausführungsbeispiels anhand der Zeichnung hervor. Es zeigenadvantageous Embodiments and developments of the invention will be apparent from the dependent claims and the following description of a Embodiment with reference to the drawing. Show it

In
einer weiteren, hier nicht dargestellten Ausführungsvariante
können auch mehrere fest vorgegebene Symbole an einem Ort
des Anzeigeelements räumlich wirkend dargestellt werden.
Dies kann dadurch erreicht werden, dass die verschiedenen Symbolformen
den verschiedenen OLED-Schichten
So kann beispielsweise eine erste, dritte, fünfte OLED-Schicht die Form eines ersten Symbols ausbilden, während eine zweite, vierte und sechste OLED-Schicht die Form eines zweiten Symbols wiedergibt. Jedes Symbol kann aufgrund der Verteilung auf mehrere Anzeigeschichten in dreidimensionaler Darstellung angezeigt werden. Dabei können beide Symbole beispielsweise nacheinander, gleichzeitig, in unterschiedlichen Farben oder durch eine kinetische Animation verbunden, dargestellt werden. Des weiteren können Symbole ein- oder mehrfarbig erscheinen.So For example, a first, third, fifth OLED layer form the shape of a first symbol, while a second, fourth and sixth OLED layer reflects the shape of a second symbol. Each symbol may be due to distribution over multiple display layers be displayed in three-dimensional representation. It can both symbols, for example, successively, simultaneously, in different Colors or through a kinetic animation connected, shown become. Furthermore, symbols can be single or multi-colored appear.
Das Anzeigeelement erzeugt eine ausreichende Helligkeit um das Symbol sowohl nachts bei Dunkelheit als auch tagsüber erkennbar darzustellen. Das Anzeigeelement kann vorteilhaft in ein Bedienelement integriert sein.The Display element generates sufficient brightness around the symbol both at night in darkness and during the day recognizable display. The display element can be advantageous in a control be integrated.
