Der Erfindung liegt das technische Problem zugrunde, ein flexibles Display der eingangs genannten Art der eingangs gennanten Art zu schaffen, das hinsichtlich der Größe modular an unterschiedliche Größenverhältnisse anpassbar ist und insbesondere als Kinoleinwand, Panoramaleinwand oder Theaterkulisse verwendbar ist und bei ausreichend hoher Auflösung ein geringes optisches Übersprechen aufweist.Of the Invention is based on the technical problem of a flexible display to create the type mentioned at the beginning of the type mentioned, that in terms of size modular to different proportions is customizable and in particular as a cinema screen, panorama screen or theater backdrop is usable and at sufficiently high resolution low optical crosstalk having.
Die Lösung des technischen Problems ergibt sich durch den Gegenstand mit den Merkmalen des Anspruchs 1. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The solution the technical problem arises from the subject with the Features of claim 1. Further advantageous embodiments of Invention will become apparent from the dependent claims.
Hierzu umfasst das flexible Display eine flexible, transparente Trägerfolie, wobei auf der Trägerfolie eine Vielzahl von lichtemittierenden Elementen angeordnet sind. Jedes lichtemittierende Element kann mindestens in drei Farben emittieren, vorzugsweise Rot, Grün und Blau, wobei die Farben selektiv zu- oder abschaltbar sind. Jedem lichtemittierenden Element ist ein diffuses linsenartiges Element zugeordnet, mittels dessen die Farben gemischt und die Strahlung gerichtet wird, wobei zwischen den lichtemittierenden Elementen eine lichtundurchlässige Trennschicht angeordnet ist und unterhalb der lichtemittierenden Elemente mindestens ein thermisches Interface und ein elekirisches Interface angeordnet sind. Durch die flexible Trägerfolie kann das flexible Display an gewünschte Größen und Formen angepasst werden, wodurch auch große Leinwände oder Kulissen realisiert werden können. Die Auflösung des Displays hängt von der Größe und Dichte der lichtemittierenden Elemente ab. Insbesondere bei Großleinwänden kann dabei ein Abstand zwischen den lichtemittierenden Elementen im cm-Bereich liegen, was eine ausreichende Auflösung gewährleistet und technologisch gut handhabbar ist. Mittels der lichtundurchlässigen Trennschicht wird dabei ein unerwünschtes optisches Übersprechen zwischen zwei benachbarten lichtemittierenden Elementen vermieden. Über das thermische Interface kann dann die elektrische Verlustwärme der lichtemittierenden Elemente abgeleitet werden und über das elektrische Interface die Ansteuersignale für die lichtemittierenden Elemente zugeführt werden.For this purpose, the flexible display comprises a flexible, transparent carrier film, wherein a plurality of light-emitting elements are arranged on the carrier film. Each light-emitting element can emit at least three colors, preferably red, green and blue, the colors being selectively switchable on or off. Each light-emitting element is associated with a diffuse lenticular element, by means of which the colors are mixed and the radiation is directed, wherein between the light-emitting elements, an opaque separation layer is disposed and below the light-emitting elements at least one thermal interface and an electrical interface are arranged. Due to the flexible carrier foil, the flexible display can be adapted to desired sizes and shapes, whereby even large canvases or scenes can be realized. The resolution of the Displays depend on the size and density of the light-emitting elements. In particular, in large screens can be a distance between the light-emitting elements in the cm range, which ensures a sufficient resolution and is technologically easy to handle. By means of the opaque separating layer, an undesired optical crosstalk between two adjacent light-emitting elements is avoided. The electrical loss of heat of the light-emitting elements can then be dissipated via the thermal interface and the drive signals for the light-emitting elements can be supplied via the electrical interface.
In einer bevorzugten Ausführungsform sind die lichtemittierenden Elemente als RGB-LEDs ausgebildet. Der Vorteil von RGB-LEDs ist die relativ hohe Lichtstärke sowie deren gute Integrierbarkeit, so dass die einzelnen Elemente des flexiblen Displays in Multi-Chip-Modul-Technik realisiert werden können.In a preferred embodiment the light-emitting elements are designed as RGB LEDs. Of the The advantage of RGB LEDs is the relatively high light intensity as well as their brightness good integrability, so that the individual elements of the flexible Displays in multi-chip module technology can be realized.

Dies ermöglicht einen kompakten Aufbau, der keinen zusätzlichen Bauraum in der Fläche benötigt.In a further preferred embodiment is between the thermal interface and the electrical interface a DA converter and an amplifier stage arranged one above the other are arranged. this makes possible a compact structure that requires no additional space in the area.
In einer weiteren bevorzugten Ausführungsform ist zwischen den lichtemittierenden Elementen und der Verstärkerstufe eine Zwischenschicht angeordnet, die das thermische Interface sowie Kontakte und ein erstes elektrisches Isolationsinterface umfasst. Über die Kontakte können dann die Signale von der Verstärkerstufe zu den lichtemittierenden Elementen durchgeschleift werden, wobei über das thermische Interface die Verlustwärme der lichtemittierenden Elemente abgeleitet wird. Das elektrische Isolationsinterface verhindert hingegen insbesondere elektrische Kopplungen zwischen benachbarten lichtemittierenden Elementen.In a further preferred embodiment is between the light-emitting elements and the amplifier stage an intermediate layer arranged, which is the thermal interface as well Contacts and a first electrical isolation interface comprises. About the Contacts can then the signals from the amplifier stage are looped through to the light-emitting elements, wherein the thermal Interface the heat loss the light-emitting elements is derived. The electrical insulation interface In contrast, in particular prevents electrical couplings between adjacent light-emitting elements.
In einer weiteren bevorzugten Ausführungsform ist zwischen dem DA-Wandler und der Verstärkerstufe eine weitere Zwischenschicht angeordnet, die ein thermisches Interface, elektrische Kontakte und ein elektrisches Isolationsinterface umfasst.In a further preferred embodiment is between the DA converter and the amplifier stage another intermediate layer arranged, which has a thermal interface, electrical contacts and an electrical isolation interface comprises.
Diese Zwischenschicht dient vor allem der durchgängigen Wärmeableitung sowie der notwendigen elektrischen Verbindung zwischen den elektrischen Bauelementen.These Interlayer mainly serves the continuous heat dissipation and the necessary electrical connection between the electrical components.
In einer weiteren bevorzugten Ausführungsform ist zwischen dem DA-Wandler und dem elektrischen Interface eine weitere Zwischenschicht angeordnet, die ein thermisches Interface, elektrische Kontakte und ein elektrisches Isolationsinterface umfasst. Hierdurch wird eine Kompatibilität zwischen den Schichten bezüglich ihrer thermischen Ausdehnung erreicht.In a further preferred embodiment is a between the DA converter and the electrical interface further intermediate layer arranged, which is a thermal interface, includes electrical contacts and an electrical isolation interface.
