Definitions

  • the invention relates to a composite pane with a hologram element, in particular for a holographic head-up display, a method for producing such a composite pane, and the use of such a composite pane.
  • Vehicle includes, among other things, road vehicles, aircraft, ships, agricultural machines and also work equipment.
  • Composite panes are also used in other areas. These include, for example, building glazing or information displays, e.g. in museums or as advertising displays.
  • Composite panes are often used as a head-up display (HUD) to display information.
  • An image is projected onto the laminated glass panes by means of a projection device in order to show information into the field of vision for the viewer.
  • the projection device is arranged e.g. on the dashboard, so that the projected image is reflected in the direction of the viewer on the closest glass surface of the laminated glass pane inclined towards the viewer (see, for example, patent EP 0420 228 B1 or DE 102012 211 729 A1).
  • Functional holograms and, for example, reflection holograms, which are laminated between the panes of a composite pane, can be used for head-up displays.
  • the functional hologram can contain information recorded therein.
  • the reflection hologram light emitted by a projector can be activated and the information recorded in the hologram can thus be reproduced for the viewer.
  • Head-up displays comprising holographic optical elements are known, for example, from WO 2012/156124 A1, DE 102017212 451 A1, WO 2018/206314 A1 and US 2019/0056596 A1.

  • the invention relates to a composite pane at least comprising an outer pane with an outer surface and an inner surface, a first intermediate layer, a hologram element, a second intermediate layer and an inner pane with an outer surface and an inner surface.
  • the hologram element according to the invention comprises at least one layer of a holographic material. Furthermore, the hologram element according to the invention comprises at least one hologram or at least one set of holograms, produced in the layer or layers of the holographic material.
  • the set of holograms comprises a blue hologram, a green hologram and a red hologram.
  • the blue hologram can be activated by means of blue light with a wavelength in a first range and does not react to light of other wavelengths.
  • the green hologram can be activated by means of green light with a wavelength in a second range and does not react to light of other wavelengths.
  • the red hologram can be activated by means of red light with a wavelength in a third range and does not react to light of other wavelengths.
  • the hologram element is arranged between the first and the second intermediate layer, which in turn are arranged between the outer pane and the inner pane.
  • the outer pane and the inner pane each have an outer surface, ie an outer surface, and an interior-side surface, ie an inner surface, and a circumferential side surface running between them, which is also called a side edge because of its comparatively small width.
  • the outer surface denotes that main surface which is intended to face the external environment in the installed position.

Description

Verbundscheibe mit Hologrammelement Composite pane with hologram element
Die Erfindung betrifft eine Verbundscheibe mit Hologrammelement, insbesondere für ein holographisches Head-Up-Display, ein Verfahren zur Herstellung einer solchen Verbundscheibe, sowie die Verwendung einer solchen Verbundscheibe. The invention relates to a composite pane with a hologram element, in particular for a holographic head-up display, a method for producing such a composite pane, and the use of such a composite pane.
Verbundscheiben werden heutzutage an vielen Orten, insbesondere im Fahrzeugbau, verwendet. Dabei umfasst der Begriff Fahrzeug unter anderem Straßenfahrzeuge, Flugzeuge, Schiffe, landwirtschaftliche Maschinen oder auch Arbeitsgeräte. Composite panes are used in many places today, especially in vehicle construction. The term vehicle includes, among other things, road vehicles, aircraft, ships, agricultural machines and also work equipment.
Auch in anderen Bereichen werden Verbundscheiben verwendet. Hierzu zählen beispielsweise Gebäudeverglasungen oder Informationsdisplays, z.B. in Museen oder als Werbedisplays. Composite panes are also used in other areas. These include, for example, building glazing or information displays, e.g. in museums or as advertising displays.
Häufig werden Verbundscheiben auch als Head-Up-Display (HUD) zur Anzeige von Informationen verwendet. Dabei wird mittels einer Projektionsvorrichtung ein Bild auf die Verbundglasscheiben projiziert, um dem Betrachter eine Information ins Sichtfeld einzublenden. Im Fahrzeugbereich wird die Projektionseinrichtung z.B. auf dem Armaturenbrett angeordnet, so dass das projizierte Bild auf der nächstliegenden Glasfläche der zum Betrachter hin geneigten Verbundglasscheibe in Richtung des Betrachters reflektiert wird (siehe beispielsweise Patent EP 0420 228 B1 oder DE 102012 211 729 A1). Composite panes are often used as a head-up display (HUD) to display information. An image is projected onto the laminated glass panes by means of a projection device in order to show information into the field of vision for the viewer. In the vehicle area, the projection device is arranged e.g. on the dashboard, so that the projected image is reflected in the direction of the viewer on the closest glass surface of the laminated glass pane inclined towards the viewer (see, for example, patent EP 0420 228 B1 or DE 102012 211 729 A1).
Für Head-Up-Displays können Funktionshologramme und beispielsweise Reflexionshologramme genutzt werden, die zwischen den Scheiben einer Verbundscheibe einlaminiert sind. Das Funktionshologramm kann darin aufgezeichnete Informationen enthalten. Beim Reflexionshologramm kann mittels von einem Projektor abgestrahltem Licht aktiviert werden und somit die in dem Hologramm aufgezeichneten Informationen für den Betrachter wiedergegeben werden. Functional holograms and, for example, reflection holograms, which are laminated between the panes of a composite pane, can be used for head-up displays. The functional hologram can contain information recorded therein. In the case of the reflection hologram, light emitted by a projector can be activated and the information recorded in the hologram can thus be reproduced for the viewer.
Head-Up-Displays, umfassend holographische optische Elemente, sind beispielsweise WO 2012/156124 A1, DE 102017212 451 A1, WO 2018/206314 A1 und US 2019/0056596 A1 bekannt. Head-up displays comprising holographic optical elements are known, for example, from WO 2012/156124 A1, DE 102017212 451 A1, WO 2018/206314 A1 and US 2019/0056596 A1.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine verbesserte Verbundscheibe mit Hologrammelement bereitzustellen, die einfach und kostengünstig herzustellen ist. Die Aufgabe der vorliegenden Erfindung wird erfindungsgemäß durch eine Verbundscheibe gemäß Anspruch 1 gelöst. Bevorzugte Ausführungen gehen aus den Unteransprüchen hervor. The present invention is based on the object of providing an improved composite pane with a hologram element which is simple and inexpensive to manufacture. The object of the present invention is achieved according to the invention by a composite pane according to claim 1. Preferred designs emerge from the subclaims.
Die Erfindung betrifft eine Verbundscheibe mindestens umfassend eine Außenscheibe mit einer Außenfläche und einer Innenfläche, eine erste Zwischenschicht, ein Hologrammelement, eine zweite Zwischenschicht und eine Innenscheibe mit einer Außenfläche und einer Innenfläche.

Das erfindungsgemäße Hologrammelement umfasst mindestens eine Schicht eines holographischen Materials. Des Weiteren umfasst das erfindungsgemäße Hologrammelement mindestens ein Hologramm oder mindestens einen Satz von Hologrammen, hergestellt in der oder den Schichten des holographischen Materials. The hologram element according to the invention comprises at least one layer of a holographic material. Furthermore, the hologram element according to the invention comprises at least one hologram or at least one set of holograms, produced in the layer or layers of the holographic material.
In einer vorteilhaften Ausgestaltung eines erfindungsgemäßen Hologrammelements umfasst der Satz von Hologrammen ein blaues Hologramm, ein grünes Hologramm und ein rotes Hologramm. Das blaue Hologramm ist mittels blauen Lichts mit einer Wellenlänge in einem ersten Bereich aktivierbar und reagiert nicht auf Licht anderer Wellenlängen. Das grüne Hologramm ist mittels grünen Lichts mit einer Wellenlänge in einem zweiten Bereich aktivierbar und reagiert nicht auf Licht anderer Wellenlängen. Das rote Hologramm ist mittels roten Lichts mit einer Wellenlänge in einem dritten Bereich aktivierbar reagiert und nicht auf Licht anderer Wellenlängen. In an advantageous embodiment of a hologram element according to the invention, the set of holograms comprises a blue hologram, a green hologram and a red hologram. The blue hologram can be activated by means of blue light with a wavelength in a first range and does not react to light of other wavelengths. The green hologram can be activated by means of green light with a wavelength in a second range and does not react to light of other wavelengths. The red hologram can be activated by means of red light with a wavelength in a third range and does not react to light of other wavelengths.
In der erfindungsgemäßen Verbundscheibe ist das Hologrammelement zwischen der ersten und der zweiten Zwischenschicht angeordnet, die wiederum zwischen der Außenscheibe und der Innenscheibe angeordnet sind. In the composite pane according to the invention, the hologram element is arranged between the first and the second intermediate layer, which in turn are arranged between the outer pane and the inner pane.
Die Außenscheibe und die Innenscheibe weisen wie oben beschrieben jeweils eine außenseitige Oberfläche, d.h. eine Außenfläche, und eine innenraumseitige Oberfläche, d.h. eine Innenfläche, auf und eine dazwischen verlaufende, umlaufende Seitenfläche, die wegen ihrer vergleichsweise geringen Breite auch Seitenkante genannt wird. Mit Außenfläche wird im Sinne der Erfindung diejenige Hauptfläche bezeichnet, welche dafür vorgesehen ist, in Einbaulage der äußeren Umgebung zugewandt zu sein. Mit Innenfläche wird im Sinne der Erfindung diejenige Hauptfläche bezeichnet, welche dafür vorgesehen ist, in Einbaulage dem Innenraum zugewandt zu sein. Die Innenfläche der Außenscheibe und die Außenfläche der Innenscheibe sind in der erfindungsgemäßen Verbundscheibe einander zugewandt. As described above, the outer pane and the inner pane each have an outer surface, ie an outer surface, and an interior-side surface, ie an inner surface, and a circumferential side surface running between them, which is also called a side edge because of its comparatively small width. For the purposes of the invention, the outer surface denotes that main surface which is intended to face the external environment in the installed position. In the context of the invention, the inner surface denotes that main surface which is intended to be used in the installation position To be interior facing. The inner surface of the outer pane and the outer surface of the inner pane face one another in the composite pane according to the invention.
Ist die Verbundscheibe dafür vorgesehen, in einer Fensteröffnung eines Fahrzeugs oder eines Gebäudes einen Innenraum gegenüber der äußeren Umgebung abzutrennen, so wird mit Innenscheibe im Sinne der Erfindung die dem Innenraum (Fahrzeuginnenraum) zugewandte Scheibe bezeichnet. Mit Außenscheibe wird die der äußeren Umgebung zugewandte Scheibe bezeichnet. If the composite pane is intended to separate an interior space from the external environment in a window opening of a vehicle or a building, the term “interior pane” in the context of the invention denotes the pane facing the interior space (vehicle interior). The outer pane is referred to as the pane facing the external environment.
Das erfindungsgemäße Hologrammelement besteht aus mindestens einer Schicht eines holographischen Materials oder aus mindestens einer Schicht eines holographischen Materials und einer Substratschicht. The hologram element according to the invention consists of at least one layer of a holographic material or of at least one layer of a holographic material and a substrate layer.
Bevorzugt umfasst das Hologrammelement als holographisches Material ein Photopolymer. Das erfindungsgemäße Photopolymer ist vorteilhafterweise gegenüber Weichmachern oder Chemikalien aus den Zwischenschichten und insbesondere aus jeder der unmittelbar an die Photopolymer-Schicht grenzenden Zwischenschichten beständig. The hologram element preferably comprises a photopolymer as the holographic material. The photopolymer according to the invention is advantageously resistant to plasticizers or chemicals from the intermediate layers and in particular from each of the intermediate layers directly adjoining the photopolymer layer.
In einer vorteilhaften Ausgestaltung des erfindungsgemäßen Hologrammelements beträgt die Dicke der Photopolymer-Schicht von 5 pm bis 300 pm, bevorzugt von 10 pm bis 50 pm und beispielsweise 16 pm. In an advantageous embodiment of the hologram element according to the invention, the thickness of the photopolymer layer is from 5 μm to 300 μm, preferably from 10 μm to 50 μm and, for example, 16 μm.
In einer vorteilhaften Ausgestaltung einer erfindungsgemäßen Verbundscheibe, erstreckt sich das holographische Material vollflächig über die gesamte Verbundscheibe oder im Wesentlichen vollflächig, d.h. vollflächig abzüglich eines umlaufenden Randbereichs von beispielsweise 20 mm, der in der Regel von einem rahmenartigen dunklen Abdeckdruck verdeckt ist, erstreckt. In einer alternativen Ausgestaltung kann sich das holographische Material auch nur abschnittsweise über die Verbundscheibe erstrecken. In an advantageous embodiment of a composite pane according to the invention, the holographic material extends over the entire surface or essentially over the entire surface, i.e. over the entire surface minus a circumferential edge area of, for example, 20 mm, which is usually covered by a frame-like dark cover print. In an alternative embodiment, the holographic material can also only extend over the composite pane in sections.
Die erfindungsgemäße Verbundscheibe umfasst zwei zwischen der Außenscheibe und der Innenscheibe angeordnete Zwischenschichten, wobei das Hologrammelement zwischen der ersten Zwischenschicht und der zweiten Zwischenschicht angeordnet ist. The composite pane according to the invention comprises two intermediate layers arranged between the outer pane and the inner pane, the hologram element being arranged between the first intermediate layer and the second intermediate layer.
In einer vorteilhaften Ausgestaltung einer erfindungsgemäßen Verbundscheibe besteht das Hologrammelement ausschließlich aus einem holographischen Material. Das holgraphische Material besteht bevorzugt aus einer oder mehreren Schichten eines Photopolymers, bevorzugt aus genau einer Schicht eines Photopolymers. Die Dicke des holographischen Materials beträgt dann bevorzugt von 5 pm bis 300 pm, besonders bevorzugt von 10 pm bis 50 pm und beispielsweise 16 pm. Derartige Schichtdicken haben den Vorteil, dass die Schicht des holographischen Materials freitragend ist und als eine folienartige Schicht transferiert werden kann. In an advantageous embodiment of a composite pane according to the invention, the hologram element consists exclusively of a holographic material. The holgraphic Material preferably consists of one or more layers of a photopolymer, preferably exactly one layer of a photopolymer. The thickness of the holographic material is then preferably from 5 μm to 300 μm, particularly preferably from 10 μm to 50 μm and, for example, 16 μm. Such layer thicknesses have the advantage that the layer of the holographic material is self-supporting and can be transferred as a film-like layer.
Besteht das Hologrammelement nur aus einer oder mehreren Schichten des holographischen Materials, dann sind sowohl das holographische Material und die erste Zwischenschicht als auch das holographische Material und die zweite Zwischenschicht unmittelbar aufeinander angeordnet oder mit anderen Worten unmittelbar miteinander verbunden. If the hologram element consists of only one or more layers of the holographic material, then both the holographic material and the first intermediate layer and also the holographic material and the second intermediate layer are arranged directly on top of one another or, in other words, directly connected to one another.
In einer weiteren vorteilhaften Ausgestaltung einer erfindungsgemäßen Verbundscheibe besteht das Hologrammelement ausschließlich aus mindestens einer Schicht des holographischen Materials sowie einer Substratschicht, auf der das holographische Material angeordnet ist. Das holographische Material besteht bevorzugt aus einer oder mehreren Schichten eines Photopolymers, bevorzugt genau aus einer Schicht eines Photopolymers. Die Dicke des holographischen Materials beträgt dann bevorzugt 5 pm bis 300 pm, besonders bevorzugt von 10 pm bis 50 pm und beispielsweise 16 pm. Ein derartiger Aufbau hat den Vorteil, dass die Schichten des holographischen Materials dünner ausgebildet werden können, was die optischen Eigenschaften der des Hologrammelements verbessert. In a further advantageous embodiment of a composite pane according to the invention, the hologram element consists exclusively of at least one layer of the holographic material and a substrate layer on which the holographic material is arranged. The holographic material preferably consists of one or more layers of a photopolymer, preferably precisely one layer of a photopolymer. The thickness of the holographic material is then preferably 5 .mu.m to 300 .mu.m, particularly preferably from 10 .mu.m to 50 .mu.m and, for example, 16 .mu.m. Such a structure has the advantage that the layers of the holographic material can be made thinner, which improves the optical properties of the hologram element.
In einer solchen Ausgestaltung ist die mindestens eine Schicht des holographischen Materials unmittelbar mit der ersten Zwischenschicht oder der zweiten Zwischenschicht verbunden. Die dem holographischen Material abgewandte Seite der Substratschicht ist dann mit der jeweils anderen Zwischenschicht unmittelbar verbunden. In such a configuration, the at least one layer of the holographic material is directly connected to the first intermediate layer or the second intermediate layer. The side of the substrate layer facing away from the holographic material is then directly connected to the respective other intermediate layer.
Die erfindungsgemäße Substratschicht enthält vorteilhafterweise eine Schicht aus Polyamid (PA), Cellulosetriacetat (TAC) und/oder Polyethylenterephthalat (PET) oder besteht aus einer Schicht dieser Materialien. Die Schichtdicke der Substratschicht beträgt bevorzugt von 20 pm bis 300 pm, besonders bevorzugt von 30 pm bis 150 pm und insbesondere von 35 pm bis 60 pm. The substrate layer according to the invention advantageously contains a layer made of polyamide (PA), cellulose triacetate (TAC) and / or polyethylene terephthalate (PET) or consists of a layer of these materials. The layer thickness of the substrate layer is preferably from 20 μm to 300 μm, particularly preferably from 30 μm to 150 μm and in particular from 35 μm to 60 μm.
In einer weiteren Ausführungsform umfasst das erfindungsgemäße Hologrammelement zusätzlich zu dem ersten Satz von Hologrammen, hergestellt in eine oder mehrere Schichten des holographischen Materials, einen zweiten Satz von Hologrammen. Dieser zweite Satz von Hologrammen umfasst beispielsweise ein blaues Hologramm, das mittels blauen Lichts mit einer Wellenlänge in dem ersten Bereich aktivierbar ist und nicht auf Licht anderer Wellenlängen reagiert, ein grünes Hologramm, das mittels grünen Lichts mit einer Wellenlänge in dem zweiten Bereich aktivierbar ist und nicht auf Licht anderer Wellenlängen reagiert, und ein rotes Hologramm, dass mittels roten Lichts mit einer Wellenlänge in dem dritten Bereich aktivierbar ist und nicht auf Licht anderer Wellenlängen reagiert. In a further embodiment, the hologram element according to the invention comprises, in addition to the first set of holograms, produced in one or more layers of the holographic material, a second set of holograms. This second sentence of holograms includes, for example, a blue hologram that can be activated by means of blue light with a wavelength in the first range and does not react to light of other wavelengths, a green hologram that can be activated by means of green light with a wavelength in the second range and not to light other wavelengths reacts, and a red hologram that can be activated by means of red light with a wavelength in the third range and does not react to light of other wavelengths.
Die erste Zwischenschicht und die zweite Zwischenschicht sind bevorzugt thermoplastische Zwischenschichten. In einer vorteilhaften Ausgestaltung enthalten die erste thermoplastische Zwischenschicht und die zweite thermoplastische Zwischenschicht unabhängig voneinander zumindest Polyvinylbutyral (PVB), Ethylenvinylacetat (EVA), Polyurethan (PU) oder Gemische oder Copolymere oder Derivate davon, bevorzugt Polyvinylbutyral (PVB), besonders bevorzugt Polyvinylbutyral (PVB) und dem Fachmann bekannte Additive wie beispielsweise Weichmacher. Bevorzugt besteht jede Zwischenschicht unabhängig voneinander aus einem der soeben genannten Materialien. The first intermediate layer and the second intermediate layer are preferably thermoplastic intermediate layers. In an advantageous embodiment, the first thermoplastic intermediate layer and the second thermoplastic intermediate layer contain, independently of one another, at least polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), polyurethane (PU) or mixtures or copolymers or derivatives thereof, preferably polyvinyl butyral (PVB), particularly preferably polyvinyl butyral (PVB) ) and additives known to those skilled in the art, such as plasticizers, for example. Each intermediate layer is preferably composed of one of the materials just mentioned, independently of one another.
Die Dicke jeder thermoplastischen Zwischenschicht beträgt vorteilhafterweise von 0,030 mm bis 1 mm, bevorzugt von 30 pm bis 300 pm und besonders bevorzugt von 50 pm bis 100 pm oder von 300 pm bis 800 pm und beispielsweise 380 pm oder 760 pm. Es versteht sich, dass die erste und die zweite Zwischenschicht gleich oder unterschiedlich dick ausgebildet sein können. The thickness of each thermoplastic intermediate layer is advantageously from 0.030 mm to 1 mm, preferably from 30 pm to 300 pm and particularly preferably from 50 pm to 100 pm or from 300 pm to 800 pm and, for example, 380 pm or 760 pm. It goes without saying that the first and the second intermediate layer can have the same or different thicknesses.
Alternativ können eine oder beide Zwischenschichten einen optisch-transparenten Klebstoff (OCA, engl. Optically clear adhesive) enthalten oder daraus bestehen. Die Dicke jeder Zwischenschicht aus optisch-transparenten Kunststoff beträgt vorteilhafterweise von 0,030 mm bis 1 mm, bevorzugt von 30 pm bis 300 pm und besonders bevorzugt von 50 pm bis 100 pm. Deratige optisch transparente Klebstoffe bestehen oder enthalten üblicherweise acryl- oder acrylat-basierten Klebstoffe. Alternatively, one or both intermediate layers can contain or consist of an optically transparent adhesive (OCA). The thickness of each intermediate layer made of optically transparent plastic is advantageously from 0.030 mm to 1 mm, preferably from 30 μm to 300 μm and particularly preferably from 50 μm to 100 μm. Such optically transparent adhesives consist or usually contain acrylic or acrylate-based adhesives.
Die erste Zwischenschicht und die zweite Zwischenschicht können unabhängig voneinander durch eine einzelne Folie oder Schicht ausgebildet sein oder auch durch mehr als eine Folie oder Schicht. The first intermediate layer and the second intermediate layer can be formed independently of one another by a single film or layer or also by more than one film or layer.
Die erste Zwischenschicht und/oder die zweite Zwischenschicht können unabhängig voneinander auch eine funktionale Zwischenschicht sein, insbesondere eine Zwischenschicht mit akustisch dämpfenden Eigenschaften, eine Infrarotstrahlung reflektierende Zwischenschicht, eine Infrarotstrahlung absorbierende Zwischenschicht, eine UV-Strahlung absorbierende Zwischenschicht, eine zumindest abschnittsweise gefärbte Zwischenschicht und/oder eine zumindest abschnittsweise getönte Zwischenschicht. So kann die erste Zwischenschicht oder die zweite Zwischenschicht beispielsweise auch eine Bandfilterfolie sein. Dies gilt insbesondere für thermoplastische Zwischenschichten. The first intermediate layer and / or the second intermediate layer can also be a functional intermediate layer, in particular an intermediate layer, independently of one another with acoustic damping properties, an intermediate layer which reflects infrared radiation, an intermediate layer which absorbs infrared radiation, an intermediate layer which absorbs UV radiation, an intermediate layer which is at least partially colored and / or an intermediate layer which is tinted at least partially. For example, the first intermediate layer or the second intermediate layer can also be a belt filter film. This applies in particular to thermoplastic intermediate layers.
Zur Verbesserung der Haftung können sowohl die Oberflächen der Scheiben, der Zwischenschichten, der Substratschicht und/oder der Photopolymer-Schicht chemisch vorbehandelt oder Plasma-behandelt werden oder es kann ein Primer aufgetragen werden. To improve the adhesion, both the surfaces of the panes, the intermediate layers, the substrate layer and / or the photopolymer layer can be chemically pretreated or plasma-treated, or a primer can be applied.
Die Außenscheibe und die Innenscheibe sind bevorzugt aus Glas gefertigt, besonders bevorzugt aus Kalk-Natron-Glas, wie es für Fensterscheiben üblich ist. Die Scheiben können aber auch aus anderen Glassorten gefertigt sein, beispielsweise Quarzglas, Borosilikatglas oder Alumino-Silikat-Glas, oder aus starren klaren Kunststoffen, beispielsweise Polycarbonat oder Polymethylmethacrylat. Die Scheiben können klar oder auch getönt oder gefärbt sein. Sofern die Verbundscheibe als Windschutzscheibe verwendet wird, sollte diese im zentralen Sichtbereich eine ausreichende Lichttransmission aufweisen, bevorzugt mindestens 70 % im Haupt-Durchsichtbereich A gemäß ECE-R43. The outer pane and the inner pane are preferably made of glass, particularly preferably of soda-lime glass, as is customary for window panes. The panes can, however, also be made from other types of glass, for example quartz glass, borosilicate glass or aluminosilicate glass, or from rigid, clear plastics, for example polycarbonate or polymethyl methacrylate. The panes can be clear or tinted or colored. If the composite pane is used as a windshield, it should have sufficient light transmission in the central viewing area, preferably at least 70% in the main viewing area A in accordance with ECE-R43.
Die Außenscheibe, die Innenscheibe, die erste Zwischenschicht und/oder die zweite Zwischenschicht können geeignete, an sich bekannte Beschichtungen aufweisen, beispielsweise Antireflexbeschichtungen, Antihaftbeschichtungen, Antikratzbeschichtungen, photokatalytische Beschichtungen oder Sonnenschutzbeschichtungen oder Low-E- Beschichtungen. Derartige Beschichtungen sind vorteilhafterweise unmittelbar auf der Außenscheibe und/oder der Innenscheibe angeordnet. Bei Sonnenschutzbeschichtungen sind spektral möglichst neutrale Beschichtungen bevorzugt und/oder diese sind bevorzugt auf der ersten Zwischenschicht oder auf der Außenscheibe, insbesondere auf der I nnenfläche der Außenscheibe aufgebracht. The outer pane, the inner pane, the first intermediate layer and / or the second intermediate layer can have suitable coatings known per se, for example anti-reflective coatings, non-stick coatings, anti-scratch coatings, photocatalytic coatings or sun protection coatings or low-E coatings. Such coatings are advantageously arranged directly on the outer pane and / or the inner pane. In the case of sun protection coatings, coatings that are as spectrally neutral as possible are preferred and / or these are preferably applied to the first intermediate layer or to the outer pane, in particular to the inner surface of the outer pane.
In einer vorteilhaften Ausgestaltung befinden sich zwischen den Zwischenschichten und dem Hologrammelement keine weiteren Beschichtungen. In an advantageous embodiment, there are no further coatings between the intermediate layers and the hologram element.
Die Dicke der Außenscheibe und der Innenscheibe kann breit variieren und so den Erfordernissen im Einzelfall angepasst werden. Die Außenscheibe und die Innenscheibe weisen bevorzugt Dicken von 0,5 mm bis 5 mm auf, besonders bevorzugt von 1 mm bis 3 mm, ganz besonders bevorzugt von 1,6 mm bis 2,1 mm. Beispielsweise weist die Außenscheibe eine Dicke von 2,1 mm auf und die Innenscheibe eine Dicke von 1,6 mm auf. Es kann sich bei der Außenscheibe oder insbesondere der Innenscheibe aber auch um Dünnglas mit einer Dicke von beispielsweise 0,55 mm handeln. The thickness of the outer pane and the inner pane can vary widely and thus be adapted to the requirements of the individual case. The outer pane and the inner pane preferably have thicknesses from 0.5 mm to 5 mm, particularly preferably from 1 mm to 3 mm, very particularly preferably from 1.6 mm to 2.1 mm. For example, the outer pane has a thickness of 2.1 mm and the inner pane has a thickness of 1.6 mm. However, the outer pane or in particular the inner pane can also be thin glass with a thickness of, for example, 0.55 mm.
Ein weiterer Aspekt der Erfindung umfasst eine Projektionsanordnung zur Darstellung von Informationen für einen Betrachter, mindestens umfassend eine erfindungsgemäße Verbundscheibe und einen Projektor, der von innen auf das Hologramm in dem Hologrammelement gerichtet ist. Die erfindungsgemäße Verbundscheibe kann dabei wie oben in den verschiedenen Ausführungsformen beschrieben ausgebildet sein. Another aspect of the invention comprises a projection arrangement for displaying information for a viewer, at least comprising a composite pane according to the invention and a projector which is directed from the inside onto the hologram in the hologram element. The composite pane according to the invention can be designed as described above in the various embodiments.
Es versteht sich, dass, sofern die erfindungsgemäße Verbundscheibe neben einem ersten Satz von Hologrammen einen zweiten Satz von Hologrammen aufweist, der Projektor von innen sowohl auf den ersten Satz von Hologrammen als auch auf den zweiten Satz von Hologrammen gerichtet ist. Alternativ kann die Projektionsanordnung auch zwei Projektoren umfassen, wobei einer von innen auf den ersten Satz von Hologrammen und einer von innen auf den zweiten Satz von Hologrammen gerichtet ist. It goes without saying that if the laminated pane according to the invention has a second set of holograms in addition to a first set of holograms, the projector is directed from the inside onto both the first set of holograms and the second set of holograms. Alternatively, the projection arrangement can also comprise two projectors, one being directed from the inside onto the first set of holograms and one from the inside onto the second set of holograms.
Der Projektor sendet Licht mit Wellenlängen aus, auf die die Hologramme des ersten Satzes an Hologrammen ansprechen. The projector emits light at wavelengths to which the holograms of the first set of holograms respond.
Bei Vorhandensein von zwei Sätzen von Hologrammen sendet der Projektor, bzw. bei Vorhandensein von zwei Projektoren die Projektoren, Licht mit Wellenlängen aus, auf die sowohl die Hologramme des ersten Satzes an Hologrammen als auch die Hologramme des zweiten Satzes an Hologrammen ansprechen If there are two sets of holograms, the projector, or if there are two projectors, the projectors, emit light with wavelengths to which both the holograms of the first set of holograms and the holograms of the second set of holograms respond
Laserprojektoren sind bevorzugt, da sich mit diesen in einfacher Weise sehr diskrete Wellenlängen erzielen lassen. Laser projectors are preferred because they can be used to achieve very discrete wavelengths in a simple manner.

In an advantageous embodiment of the method according to the invention, the intermediate layers are designed as thermoplastic intermediate layers and the stack of layers is connected by lamination, for example in an autoclave, by calendering processes or by other lamination processes.
Bei Verwendung von mindestens einer Zwischenschicht aus einem optisch-transparenten Klebstoff kann die Verbindung auch durch UV-Licht oder Temperaturerhöhung erfolgen. When using at least one intermediate layer made of an optically transparent adhesive, the connection can also take place by means of UV light or an increase in temperature.
In einer vorteilhaften Ausführungsform des erfindungsgemäßen Verfahrens wird vor, während oder nach den Schritten a), b) oder c) ein Hologrammelement hergestellt, indem ein Hologramm oder ein Satz von Hologrammen in die eine oder mehrere Schichten des holographischen Materials eingebracht werden, insbesondere durch Belichtung.

Fig. 1 zeigt einen Querschnitt durch eine Ausgestaltung einer erfindungsgemäßen Projektionsanordnung 101. Die Projektionsanordnung 101 umfasst eine Verbundscheibe 100 beispielsweise gemäß der in den folgenden Figuren 2 oder 3 gezeigten Ausführungsform und einen Projektor 18. Der Projektor 18 ist beispielsweise innen angeordnet, d.h. auf einer einem Innenraum eines Fahrzeugs oder eines Gebäudes zugewandten Seite. In der Fig. 1 ist der Strahlengang für von dem Projektor 18 ausgehendem Licht dargestellt. Das von dem Projektor 18 ausgehende Licht trifft auf das Hologrammelement 4 und aktiviert das Hologramm. Das vom Projektor 18 abgestrahlte Licht wird von dem Hologramm reflektiert, so dass das Hologramm von einem Betrachter 10 als virtuelles oder reales Bild auf der von ihm abgewandten Seite der Verbundscheibe 100 wahrgenommen wird, wenn sich seine Augen innerhalb der sogenannten Eyebox E befinden. Der Strahlengang des von dem Projektor ausgehenden Lichts ist in der Fig. 1 durch Pfeile dargestellt, die vom Projektor 18 zum Hologrammelement 4 und vom Hologrammelement 4 zur Eyebox E reichen. 1 shows a cross section through an embodiment of a projection arrangement 101 according to the invention. The projection arrangement 101 comprises a composite pane 100, for example according to the embodiment shown in the following FIGS Interior of a vehicle or a building facing side. In FIG. 1, the beam path for light emanating from the projector 18 is shown. The light emanating from the projector 18 hits the hologram element 4 and activates the hologram. The light emitted by the projector 18 is reflected by the hologram, so that the hologram is perceived by a viewer 10 as a virtual or real image on the side of the laminated pane 100 facing away from him when his eyes are located within the so-called eyebox E. The beam path of the light emanating from the projector is shown in FIG. 1 by arrows which extend from the projector 18 to the hologram element 4 and from the hologram element 4 to the eyebox E.
Fig. 2 zeigt einen Querschnitt einer Ausgestaltung einer erfindungsgemäßen Verbundscheibe 100. In der in der Fig. 2 gezeigten Ausführungsform weist die Verbundscheibe 100 eine Außenscheibe 1 mit einer Innenfläche I und einer Außenfläche II, eine erste thermoplastischen Zwischenschicht 3, ein Hologrammelement 4, eine zweite thermoplastische Zwischenschicht 5 und eine Innenscheibe 1 mit einer Außenfläche III und einer Innenfläche IV auf. 2 shows a cross section of an embodiment of a composite pane 100 according to the invention. In the embodiment shown in FIG thermoplastic intermediate layer 5 and an inner pane 1 with an outer surface III and an inner surface IV.
In der in der Fig. 2 gezeigten Ausführungsform ist das Hologrammelement 4 zwischen der Außenscheibe 1 und der Innenscheibe 2 angeordnet. Die erste thermoplastische Schicht 3 ist zwischen der Außenscheibe 1 und dem Hologrammelement 4 angeordnet und beispielsweise mit dem Hologrammelement 4 unmittelbar verbunden Des Weiteren ist die zweite thermoplastische Schicht 5 zwischen dem Hologrammelement 4 und der Innenscheibe 2 angeordnet und beispielsweise mit dem Hologrammelement 4 unmittelbar verbunden. Es versteht sich, dass auf der Außenscheibe 1 und/oder der Innenscheibe 2 und insbesondere zwischen der Außenscheibe 1 und der ersten Zwischenschicht 3 und/oder zwischen der zweiten Zwischenschicht 5 und der Innenscheibe 2 weitere transparente oder opake Schichten auf den Scheiben angeordnet sein können, beispielsweise IRR-reflektierende Schichten oder Siebdruck-Schichten. Des Weiteren kann auf der Innenseite IV der Innenscheibe 2 eine oder mehrere weitere transparente Schichten, beispielsweise ein oder mehrere Low-E-Schichten angeordnet sein. In the embodiment shown in FIG. 2, the hologram element 4 is arranged between the outer pane 1 and the inner pane 2. The first thermoplastic layer 3 is arranged between the outer pane 1 and the hologram element 4 and, for example, directly connected to the hologram element 4. Furthermore, the second thermoplastic layer 5 is arranged between the hologram element 4 and the inner pane 2 and, for example, directly connected to the hologram element 4. It goes without saying that on the outer pane 1 and / or the inner pane 2 and in particular between the outer pane 1 and the first intermediate layer 3 and / or between the second intermediate layer 5 and the inner pane 2, further transparent or opaque layers can be arranged on the panes, for example IRR-reflective layers or screen-printed layers. Furthermore, one or more further transparent layers, for example one or more low-E layers, can be arranged on the inside IV of the inner pane 2.
Die Außenscheibe 1 besteht beispielsweise aus Kalk-Natron-Glas und ist 2,1 mm dick. Die Innenscheibe 2 besteht beispielsweise aus Kalk-Natron-Glas und ist 1,6 mm dick. The outer pane 1 consists, for example, of soda-lime glass and is 2.1 mm thick. The inner pane 2 consists, for example, of soda-lime glass and is 1.6 mm thick.
Die erste Zwischenschicht 3 und die zweite Zwischenschicht 5 sind beispielsweise als thermoplastische Zwischenschichten ausgebildet und bestehen in der in der Fig. 2 gezeigten Ausführungsform beispielsweise aus Polyvinylbutyral (PVB). Sie sind beispielsweise jeweils 0,76 mm dick. Es versteht sich, dass eine oder beide der Zwischenschichten auch aus anderen Materialien, beispielsweise thermoplastischem EVA, thermoplastischem PU oder aus einem optisch-transparenten Klebstoff, ausgebildet sein können. Es versteht sich auch, dass eine oder beide der Zwischenschichten andere Dicken aufweisen können, beispielsweise 0,38 mm. The first intermediate layer 3 and the second intermediate layer 5 are designed, for example, as thermoplastic intermediate layers and, in the embodiment shown in FIG. 2, consist, for example, of polyvinyl butyral (PVB). For example, they are each 0.76 mm thick. It goes without saying that one or both of the intermediate layers can also be formed from other materials, for example thermoplastic EVA, thermoplastic PU or from an optically transparent adhesive. It is also understood that one or both of the intermediate layers can have other thicknesses, for example 0.38 mm.
Das Hologrammelement 4 besteht in der in der Fig. 2 gezeigten Ausführungsform aus einem Photopolymer als holographisches Material. In the embodiment shown in FIG. 2, the hologram element 4 consists of a photopolymer as the holographic material.
Fig. 3 zeigt einen Querschnitt einer weiteren Ausgestaltung einer erfindungsgemäßen Verbundscheibe 100. In der in der Fig. 3 gezeigten Ausführungsform weist die Verbundscheibe 100 eine Außenscheibe 1 mit einer Innenfläche I und einer Außenfläche II, eine erste thermoplastischen Zwischenschicht 3, ein Hologrammelement 4 und eine zweite thermoplastische Zwischenschicht 5 auf. 3 shows a cross section of a further embodiment of a composite pane 100 according to the invention. In the embodiment shown in FIG second thermoplastic intermediate layer 5.
Die in der Fig. 3 gezeigte Ausführungsform unterscheidet sich somit von der in der Fig. 2 gezeigten insbesondere dadurch, dass das Hologrammelement 4 aus einer Schicht aus holographischem Material 16 und einer Substratschicht 15 besteht. Die Substratschicht 15 besteht beispielsweise aus Polyethylentherephthalat (PET) und weißt eine Dicke von 35 pm auf. Bei dem holographischen Material 16 kann es sich beispielsweise um ein Photopolymer mit einer Dicke von beispielsweise 16 pm handeln. Das Photopolymer ist besonders beständig gegenüber von Weichmachern und anderen Chemikalien, die in der zweiten Zwischenschicht 5 enthalten sind und in die Schicht aus holographischem Material 16 diffundieren können. The embodiment shown in FIG. 3 thus differs from that shown in FIG. 2 in particular in that the hologram element 4 consists of a layer of holographic material 16 and a substrate layer 15. The substrate layer 15 consists, for example, of polyethylene terephthalate (PET) and has a thickness of 35 μm. The holographic material 16 can be, for example, a photopolymer with a thickness of, for example, 16 μm. The photopolymer is particularly resistant to plasticizers and other chemicals that are contained in the second intermediate layer 5 and can diffuse into the layer of holographic material 16.
In der in der Fig. 3 gezeigten Ausführungsform ist die Außenscheibe 1 über die Innenfläche II mit der ersten thermoplastischen Zwischenschicht 3 verbunden. Die zweite thermoplastische Zwischenschicht 5 ist hier beispielsweise über die Substratschicht 15 mit dem Hologrammelement 4 verbunden. Das Hologrammelement 4 ist wiederum über die Schicht aus holographischem Material 16 unmittelbar mit der ersten thermoplastischen Zwischenschicht 3 verbunden. In the embodiment shown in FIG. 3, the outer pane 1 is connected to the first thermoplastic intermediate layer 3 via the inner surface II. The second thermoplastic intermediate layer 5 is here connected to the hologram element 4 via the substrate layer 15, for example. The hologram element 4 is in turn connected directly to the first thermoplastic intermediate layer 3 via the layer of holographic material 16.
Die Außenscheibe besteht beispielsweise aus Kalk-Natron-Glas und ist 2,1 mm dick. Die Innenscheibe 2 besteht beispielsweise aus Kalk-Natron-Glas und ist 1,6 mm dick. The outer pane is made of soda-lime glass, for example, and is 2.1 mm thick. The inner pane 2 consists, for example, of soda-lime glass and is 1.6 mm thick.
Die erste thermoplastische Zwischenschicht 3 und die zweite thermoplastische Zwischenschicht 5 bestehen in der in der Fig. 1 gezeigten Ausführungsform beispielsweise aus Polyvinylbutyral (PVB) und sind jeweils 0,38 mm dick. Es versteht sich, dass auch hier die unter Fig. 2 genannten Materialien sowie Material- und Schichtdicken-Kombinationen möglich sind. In the embodiment shown in FIG. 1, the first thermoplastic intermediate layer 3 and the second thermoplastic intermediate layer 5 consist, for example, of polyvinyl butyral (PVB) and are each 0.38 mm thick. It goes without saying that the materials mentioned under FIG. 2 as well as material and layer thickness combinations are possible here as well.
Fig. 4 zeigt ein Ausführungsbeispiel des erfindungsgemäßen Verfahrens zur Herstellung einer erfindungsgemäßen Verbundscheibe 100 anhand eines Flussdiagramms umfassend die Schritte: FIG. 4 shows an exemplary embodiment of the method according to the invention for producing a composite pane 100 according to the invention on the basis of a flowchart comprising the steps:
