Abstract

The invention concerns a pixel-matrix display arrangement for displaying information in transport systems. In this arrangement, a pixel is produced by an organic light-emitting element.

Description

Die Erfindung betrifft eine Pixel-Matrix-Anzeigeeinrichtung zur Informationsdarstellung in Transportsystemen wie Kraft­ fahrzeugen, Zügen, Flugzeugen oder dergleichen.The invention relates to a pixel matrix display device for displaying information in transport systems such as power vehicles, trains, airplanes or the like.

Aus der internationalen Anmeldung WO 96/23200 ist eine Anzei­ geeinrichtung für Kraftfahrzeuge mit einem Anzeigeinstrument und einer Beleuchtungseinrichtung hierfür bekannt. Die Be­ leuchtungseinrichtung wird von einer eine organische lichte­ mittierende Substanz aufweisenden Leuchtquelle gebildet. Da­ bei ist auch vorgesehen, daß Buchstaben aus einem flächenhaf­ ten Material der Leuchtquelle ausgestanzt sind, so daß eine Kombination aus Anzeige und Beleuchtung erreicht wird. Eine variable Informationsdarstellung kann allerdings durch eine solche Leuchtquelle nicht erfolgen.An indication is from the international application WO 96/23200 device for motor vehicles with a display instrument and a lighting device known for this. The Be Lighting device is an organic light from one centering substance comprising light source is formed. There at is also provided that letters from an area th material of the light source are punched out, so that a Combination of display and lighting is achieved. A variable information display can, however, by a such light source does not take place.

Es ist ferner bekannt, in Kraftfahrzeugen Pixel-Matrix-Anzeigen in Form von passiven Flüssigkristall-Displays (LCDs) sowie Displays in Aktiv-Matrix-Ansteuerung (TFT) für die Se­ kundärinstrumentierung wie beispielsweise Radio, Uhr, Bordcomputer, Navigationssystem etc. einzusetzen. Eine solche Anzeigeeinrichtung benötigt wegen fehlender eigener Leucht­ kraft der Anzeigeelemente eine Hinterleuchtung. Diese bedingt eine hohe Energieaufnahme und eine komplexe Helligkeitsrege­ lung.It is also known to use pixel matrix displays in motor vehicles in the form of passive liquid crystal displays (LCDs) as well as displays in active matrix control (TFT) for the Se instrumentation such as radio, clock, To use on-board computer, navigation system etc. Such Display device required due to the lack of its own light backlighting due to the display elements. This requires high energy consumption and complex brightness rain lung.

Es ist ein Ziel der Erfindung, eine Pixel-Matrix-Anzeige-Einrichtung bereitzustellen, die auf eine Hinterleuchtung verzichten kann.It is an object of the invention to provide a pixel matrix display device provide that on a backlight can do without.

Dieses Ziel wird mit einer Pixel-Matrix-Anzeigeeinrichtung erreicht, wie sie in Anspruch 1 definiert ist. Zweckmäßige Weiterbildungen der Erfindung sind in den Unteransprüchen an­ gegeben.This goal is achieved with a pixel matrix display device achieved as defined in claim 1. Appropriate Developments of the invention are in the dependent claims given.

Aufgrund der Realisierung der Pixel durch eine organische lichtemittierende Substanz erübrigt sich grundsätzlich eine Hinterleuchtung der gesamten Anzeigeeinrichtung.Due to the realization of the pixels by an organic a light-emitting substance is basically unnecessary Backlighting of the entire display device.

Obgleich ein organisches lichtemittierendes Anzeigeelement nicht notwendigerweise eine Diodencharakteristik aufweisen muß, werden im folgenden derartige Anzeigeelemente als orga­ nische lichtemittierende Diode (OLED) bezeichnet.Although an organic light emitting display element do not necessarily have a diode characteristic must be in the following such display elements as orga African light-emitting diode (OLED).

Im Gegensatz zu passiven und aktiven Flüssigkristall-Displays kann ein auf organischen lichtemittierenden Anzeigeelementen oder Dioden basierendes Display extrem dünn und an die Geome­ trie und Krümmung eines Trägers angepaßt hergestellt werden. Zudem können OLEDs transparent ausgeführt werden. Ein OLED-Display eignet sich damit in idealer Weise zur Unterbringung in Transportsystemen. Insbesondere kann ein solches Display optimal an die Geometrie eines Armaturenbretts eines Kraft­ fahrzeugs angepaßt werden.In contrast to passive and active liquid crystal displays can be a on organic light emitting display elements or diode-based display extremely thin and attached to the geome trie and curvature of a carrier are made to fit. OLEDs can also be designed to be transparent. A OLED display is therefore ideal for accommodation in transport systems. In particular, such a display optimal to the geometry of a dashboard of a force be adapted to the vehicle.

Ebenso ist es möglich, ein OLED-Display an einem Fenster oder einem Spiegel anzubringen. Es können daher beispielsweise An­ zeigen eines Navigationssystems auf einfache Weise direkt in einer Windschutzscheibe (Head-up Display) eines Kraftfahr­ zeugs oder die Abstandsanzeige einer Rangierhilfe in der Heckscheibe, in einem Spiegel oder in der Seitenscheibe neben dem Seitenspiegel angezeigt werden. Auch kann ein derartig angebrachtes Display mit einer Kamera aufgenommene Bilder an­ zeigen. Auf diese Weise kann beispielsweise ein die Aerodyna­ mik störender Fahrzeugaußenspiegel ersetzt werden. Ferner kann so der Abstand zu einem anderen Fahrzeug beim Einparken und Rangieren sichtbar gemacht werden sowie gänzlich auf Rückspiegel verzichtet werden.It is also possible to have an OLED display on a window or to attach a mirror. For example, An  show a navigation system in a simple way directly in a windshield (head-up display) of a motor vehicle stuff or the distance display of a maneuvering aid in the Rear window, in a mirror or in the side window next to the side mirror. One can also be such attached display with a camera demonstrate. In this way, for example, the Aerodyna mik disturbing vehicle exterior mirror to be replaced. Further the distance to another vehicle when parking and maneuvering are made visible as well as on Rear view mirrors can be dispensed with.

Im Gegensatz zu Flüssigkristall-Displays bietet ein OLED-Display einen optimalen ("paper-like") Betrachtungswinkel, so daß eine OLED-Display gleichzeitig von einem Fahrer und von Mitfahrern eines Kraftfahrzeugs genutzt werden kann.In contrast to liquid crystal displays, one offers OLED display an optimal ("paper-like") viewing angle, see above that an OLED display from a driver and from Passengers of a motor vehicle can be used.

Da ein OLED-Display auch als Folie herstellbar ist, eignet sich die Pixel-Matrix-Anzeigeeinrichtung besonders gut für die Nachrüstung eines Anzeigeinstruments in einem Fahrzeug. Es ist nur erforderlich das Display an eine geeignete Stelle zu kleben und die dazugehörige Elektronik an einer verdeckten Stelle anzubringen.Since an OLED display can also be produced as a film, it is suitable the pixel matrix display device is particularly good for retrofitting a display instrument in a vehicle. It is only necessary to put the display in a suitable place to stick and the associated electronics on a hidden Place.

Bevorzugt wird ein Pixel von einem etwa 0,5 mm.0,5 mm gro­ ßen organischen lichtemittierenden Substrat dargestellt. Nachdem aber OLEDs problemlos als mehrere Quadratzentimeter große Flächen realisierbar sind, kann ein Pixel auch als Sym­ bol, beispielsweise als Pfeil, geformt sein.A pixel is preferably approximately 0.5 mm. 0.5 mm in size organic light-emitting substrate. But after OLEDs easily as several square centimeters large areas can be realized, a pixel can also be used as a sym bol, for example, be shaped as an arrow.

Weitere Vorteile, Merkmale und Anwendungsmöglichkeiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung der Ausführungsbeispiele in Verbindung mit den Zeichnungen. Es zeigen:Further advantages, features and possible applications of the Invention result from the following description of the Exemplary embodiments in conjunction with the drawings. It demonstrate:

Fig. 1 mehrere OLED-Displays für mehrere Zusatzgeräte, FIG. 1 several OLED displays for multiple attachments,

Fig. 2 ein gemeinsames OLED-Display für mehrere Zusatzge­ räte, FIG. 2 a common OLED display councils for several Zusatzge,

Fig. 3 ein großflächiges OLED-Display zur Darstellung der Primär- und Sekundärinstrumentierung, und Fig. 3 is a large-area OLED display for showing the primary and secondary instrumentation, and

Fig. 4 OLED-Displays für Reisende auf Vorder- und Rücksit­ zen. Fig. 4 OLED displays for travelers on front and back seats.

In Fig. 1 ist ein Armaturenbrett 1 eines Kraftfahrzeugs ab­ gebildet, das sowohl herkömmliche Anzeigeinstrumente 2 als auch OLED-Displays 3 aufweist. Dabei ist die Primärinstrumen­ tierung, das heißt Informationsanzeigen über den Betriebs zu­ stand eines Kraftfahrzeugs wie Geschwindigkeit, Kühlmittel­ temperatur und dergleichen, als analoge Anzeigeinstrumente ausgeführt. Die Sekundärinstrumentierung zur Anzeige von In­ formationen, die von Zusatzeinrichtungen wie Radio, Klimaan­ lage, Uhr, Navigationssystem oder dergleichen stammen, ist als separate Pixel-Matrix-Displays basierend auf organischen lichtemittierenden Dioden ausgeführt.In Fig. 1, a dashboard 1 of a motor vehicle is formed, which has both conventional display instruments 2 and OLED displays 3 . The primary instrumentation, that is, information displays on the operating status of a motor vehicle such as speed, coolant temperature and the like, is designed as an analog display instrument. The secondary instrumentation for displaying information that comes from additional devices such as radio, air conditioning, clock, navigation system or the like is designed as a separate pixel matrix display based on organic light-emitting diodes.

Diese können beispielsweise mit Polymeren, insbesondere kon­ jugierten Polymeren, Oligomeren, kleinen organischen Molekü­ len, Nanopartikeln in geeigneten Matrizes, wie zum Beispiel Polymeren oder Mischungen hiervon, realisiert werden. Die ak­ tiven organischen Schichten können weitere anorganische und/oder organische Hilfsstoffe enthalten. Derartige Displays werden typischerweise durch Gasphasenprozesse (Aufdampfen im Vakuum) oder Flüssigphasenprozesse (Spin Coating, Rakeln) von mehreren extrem dünnen Schichten hergestellt. Bevorzugte Schichtdicken liegen im Bereich zwischen 10 und 200 nm. Eine geeignete Schichtenfolge besteht aus transparentem Substrat wie Glas oder Polymer-Folie, einer transparenten Elektrode wie Indium-Zinn-Oxid, einer Löchertransportschicht wie N,N'- Bis-(3-methyl-phenyl)-N,N'-diphenylbenzidin (TPD), einer emittierenden Schicht wie 8-Hydroxychinolin-Aluminiumsalz (AlQ3), evtl. dotiert mit einem weiteren Emitterfarbstoff wie Rubren und einer Metallgegenelektrode wie Magnesium-Silber-Legierung.These can be, for example, with polymers, especially con jugated polymers, oligomers, small organic molecules len, nanoparticles in suitable matrices, such as Polymers or mixtures thereof can be realized. The ak tive organic layers can be further inorganic  and / or contain organic auxiliaries. Such displays are typically by gas phase processes (evaporation in the Vacuum) or liquid phase processes (spin coating, knife coating) from several extremely thin layers. Preferred Layer thicknesses are in the range between 10 and 200 nm suitable layer sequence consists of transparent substrate such as glass or polymer film, a transparent electrode like indium tin oxide, a hole transport layer like N, N'- Bis- (3-methylphenyl) -N, N'-diphenylbenzidine (TPD), one emitting layer such as 8-hydroxyquinoline aluminum salt (AlQ3), possibly doped with another emitter dye such as Rubren and a metal counter electrode like Magnesium-silver alloy.

Weitere Hilfseinrichtungen wie Ansteuerelektronik, die Optik beeinflussende Einrichtungen (Microcavities), Filter, Emissi­ ons-Konversionsfilter, UV-Filter, Antireflexschichten können integriert sein. Ebenso ist eine geeignete Umhüllung oder Verkapselung als Schutz gegen mechanische Belastung, Feuch­ tigkeit sowie als Kühlung und Wärmeabführung vorhanden.Other auxiliary devices such as control electronics, optics influencing devices (microcavities), filters, emissi ons conversion filters, UV filters, anti-reflective layers can be integrated. A suitable wrapping is also or Encapsulation as protection against mechanical stress, moisture activity as well as cooling and heat dissipation.

Die erzeugten angeregten Zustände (zum Beispiel Exzitonen) regen sich unter Aussendung von sichtbarem Licht an den Chro­ mophoren oder Polymerketten ab. Mit solchen OLEDs kann das gesamte Farbspektrum des sichtbaren Lichts abgedeckt werden. Ein farbiger Bildpunkt einer Pixel-Matrix kann daher durch mehrere verschiedenfarbige OLEDs durch Überlagerung der un­ terschiedlichen Leuchtfarben oder auf herkömmliche Weise mit OLEDs einer einheitlichen Farbe und entsprechenden Farbfil­ tern gebildet werden. The generated excited states (e.g. excitons) stimulate the chro by emitting visible light mophores or polymer chains. With such OLEDs it can entire color spectrum of visible light can be covered. A colored pixel of a pixel matrix can therefore by several different colored OLEDs by overlaying the un different fluorescent colors or in a conventional way OLEDs of a uniform color and corresponding color film tern are formed.  

Dabei kann im Gegensatz zu Flüssigkristall-Displays die Hel­ ligkeit der Anzeige sehr einfach über die angelegte Spannung, den eingeprägten Strom oder die Pulsbreite geregelt werden. Daher läßt sich mit einfachen Mitteln eine automatische Hel­ ligkeitsregelung zur Nachführung der OLEDs an die aktuellen Lichtverhältnisse realisieren.In contrast to liquid crystal displays, the Hel display is very simple about the applied voltage, the impressed current or the pulse width can be regulated. Therefore, an automatic hel validity regulation for the tracking of the OLEDs to the current ones Realize lighting conditions.

Da nur kleine elektrische Leistungen zu regeln sind, reicht eine einfache Regelelektronik aus. Wegen der fehlenden lei­ stungsintensiven Hinterleuchtung und der damit verbundenen komplexen Helligkeitsregelung ist der Aufbau eines OLED-Pixel-Matrix-Displays einfacher als bei Flüssigkristall-Displays. Insbesondere gegenüber TFT-Displays ergeben sich deutliche Kostenvorteile.Since only small electrical outputs are to be regulated, it is enough a simple control electronics. Because of the missing lei intensive backlighting and the associated complex brightness control is the structure of a OLED pixel matrix displays easier than with liquid crystal displays. Compared to TFT displays in particular clear cost advantages.

In Fig. 2 werden mehrere Anzeigen der Sekundärinstrumentie­ rung in einem einzigen OLED-Display 3 wiedergegeben. Ein Dis­ play ist somit für die Wiedergabe von unterschiedlichen In­ formationsquellen wie Bordcomputer, Navigationssystem, Radio und Telefon zuständig. Da Größe und Gestalt eines OLED-Displays weitgehend beliebig ist, ist eine optimale Anpassung an die vom Innenraum eines Fahrzeugs vorgegebenen Formen mög­ lich.In Fig. 2, several displays of the secondary instrumentation are shown in a single OLED display 3 . A dis play is therefore responsible for the reproduction of different information sources such as on-board computer, navigation system, radio and telephone. Since the size and shape of an OLED display is largely arbitrary, an optimal adaptation to the shapes given by the interior of a vehicle is possible.

Bedienelemente 4 eines Bedienteils 5 wie Tasten und Schalter weisen ebenfalls eine Oberfläche auf, die als OLED-Pixel-Matrix gestaltet ist. Dabei erlaubt die Verwendung eines fle­ xiblen Substrates für die OLEDs auch die Realisierung von Be­ dienelementen als Bildschirmtasten (Softkeys). Control elements 4 of an operating part 5, such as buttons and switches, also have a surface which is designed as an OLED pixel matrix. The use of a flexible substrate for the OLEDs also enables control elements to be implemented as screen keys (softkeys).

Aufgrund des Matrix-Displays auf einem solchen Bedienelement kann dasselbe Bedienelement unterschiedliche Symbole oder Be­ schriftungen in Abhängigkeit einer gewählten Funktion (zum Beispiel Radio, Telefon oder Navigationssystem) oder eines Betriebszustands (Fenster offen/geschlossen) darstellen.Because of the matrix display on such a control element can the same control element different symbols or Be depending on a selected function (for Radio, telephone or navigation system) or one Display operating status (window open / closed).

In Fig. 3 sind nicht nur einzelne oder mehrere Instrumente der Sekundärinstrumentierung, wie oben gezeigt, durch ein OLED-Pixel-Matrix-Display ersetzt, sondern es wird sowohl die Primärinstrumentierung als auch die Sekundärinstrumentierung durch ein einziges großflächiges OLED-Display 3 dargestellt. Ferner ist ein Pixel-Matrix-Display aus transparenten OLEDs in einer Windschutzscheibe 6 integriert.In Fig. 3 not only individual or more instruments of secondary instrumentation, as shown above, are replaced by an OLED pixel matrix display, but both the primary instrumentation and the secondary instrumentation are represented by a single large-area OLED display 3 . Furthermore, a pixel matrix display made of transparent OLEDs is integrated in a windshield 6 .

Die Aufteilung der Displays ist jeweils beliebig. Die Dar­ stellung, einschließlich aller Symbole und Instrumentenanzei­ gen, ist in bezug auf ihre Anordnung und auf ihre Gestaltung frei programmierbar. Hieraus resultiert eine hohe gestalteri­ sche Freiheit bei einfacher Umsetzung eines Designs auf einen bestimmten Fahrzeugtyp. Es muß jeweils nur die Software ent­ sprechend angepaßt werden. Eine Speichereinrichtung 7 spei­ chert die programmierte Instrumentenkonfiguration ab, die über eine Steuereinrichtung 8 oder CPU ausgegeben wird.The layout of the displays is arbitrary. The representation, including all symbols and instrument displays, is freely programmable in terms of their arrangement and design. This results in a high level of design freedom with simple implementation of a design for a specific vehicle type. Only the software has to be adapted accordingly. A memory device 7 stores the programmed instrument configuration, which is output via a control device 8 or CPU.

Durch die Integration mehrerer Anzeigen in ein Display, das über eine Steuereinrichtung ansteuerbar ist, wird der Verka­ belungsaufwand gegenüber einer herkömmlichen Primärinstrumen­ tierung deutlich reduziert. Ferner sind die Herstellung und der Einbau des gezeigten OLED-Displays in wenigeren bzw. ein­ facheren Arbeitsschritten möglich. By integrating multiple ads into one display, the can be controlled via a control device, the Verka occupancy compared to a conventional primary instrument significantly reduced. Furthermore, the manufacture and the installation of the OLED display shown in less or a more specialized work steps possible.  

Neben der vom Hersteller vorgegebenen Aufteilung kann der Be­ nutzer eine individuelle Gestaltung des Displays vornehmen. So können zusätzliche Navigationspiktogramme an vom Fahrer oder Mitfahrer vorgegebenen Positionen des Bildschirms ange­ zeigt werden. Zusätzliche benutzerspezifische Symbole, wie beispielsweise ein Symbol zur Anzeige eines eingehenden Fa­ xes, können generiert und in einem bestimmten Bereich ange­ zeigt werden. Der Benutzer kann entscheiden, ob ein bestimm­ tes, vom Fahrzeughersteller in der Speichereinrichtung 7 ab­ gespeichertes Anzeigeinstrument angezeigt wird und an welchem Ort es gegebenenfalls angezeigt wird. Ferner kann er aus ei­ ner Mehrzahl von in der Speichereinrichtung 7 abgelegten De­ signs für ein bestimmtes Anzeigeinstrument, beispielsweise analoges oder digitales Instrument, auswählen. Es kann eine Vielzahl von benutzerspezifischen Konfigurationen abgespei­ chert werden. Daher kann ein Benutzer auch bei einem Mietwa­ gen seine gewohnte Benutzeroberfläche konfigurieren.In addition to the division specified by the manufacturer, the user can customize the display. Additional navigation pictograms can be displayed at positions on the screen specified by the driver or passenger. Additional user-specific symbols, such as a symbol for displaying an incoming fax, can be generated and displayed in a specific area. The user can decide whether a particular display instrument stored by the vehicle manufacturer in the storage device 7 or above is displayed and at which location it is displayed if necessary. Furthermore, he can select from a plurality of designs stored in the storage device 7 for a specific display instrument, for example an analog or digital instrument. A variety of user-specific configurations can be saved. Therefore, a user can also configure his usual user interface for a rental car.

Die angezeigte Information weist wegen der eigenen Leucht­ kraft einen sehr hohen Kontrast auf und wird daher sehr gut wahrgenommen.The information displayed shows because of its own light due to a very high contrast and therefore becomes very good perceived.
