Description

Gegenstand der Erfindung ist eine mehrschichtige Verscheibung mit elektrisch schaltbaren optischen Eigenschaften.The invention relates to a multi-layer glazing with electrically switchable optical properties.

Gemäß WIKIPEDIA (Stichwort Intelligentes Glas, Abruf 28.06.2019) definiert der Begriff intelligentes Glas (englisch Smart Glass) tönbare Verglasungen, deren Lichtdurchlässigkeit sich durch das Anlegen einer elektrischen Spannung (Elektrochromie), veränderte Lichtverhältnisse (Photochromie) oder Erwärmung (Thermochromie) verändert. Unter dem Oberbegriff intelligentes Glas werden verschiedene Techniken und Anwendungsfelder zusammengefasst. Je nach Ausführung können diese Gläser beispielsweise als Sonnenschutz dienen (Glas bleibt transparent) oder die Funktion eines Sichtschutzes (Glas wird opak) übernehmen.According to WIKIPEDIA (keyword Intelligent Glass, accessed on June 28, 2019) the term intelligent glass (English Smart Glass) defines tintable glazing, the transparency of which changes when an electrical voltage is applied (electrochromic), changed lighting conditions (photochromic) or heating (thermochromic). Various technologies and fields of application are summarized under the generic term intelligent glass. Depending on the design, these glasses can serve as sun protection (glass remains transparent) or act as a privacy screen (glass becomes opaque).

DE 10 2012 006 231 A1 betrifft eine Schichtenanordnung, die in Abhängigkeit von ihrer Temperatur die Transmission von Licht verändert, wobei die Schichtenanordnung eine erste Polarisationsschicht, eine in Abhängigkeit von der Temperatur die Polarisationseigenschaften des Lichtes beeinflussende Schaltschicht und eine zweite Polarisationsschicht sowie eine zusätzliche NIR-transmissionshindernde Schicht aufweist. DE 10 2012 006 231 A1 relates to a layer arrangement that changes the transmission of light depending on its temperature, the layer arrangement having a first polarization layer, a switching layer that influences the polarization properties of the light depending on the temperature, and a second polarization layer and an additional NIR transmission-preventing layer.

Demgegenüber besteht die Aufgabe der vorliegenden Erfindung darin, eine mehrschichtige Verscheibung bereitzustellen, die einen elektrisch schaltbaren, d.h. dimmbaren Sonnen- und Sichtschutz aufweist. Weitere wesentliche Merkmale der Verscheibung sollen sein:

  1. 1. Failsafe (ausfallsicher im stromlosen Zustand)
  2. 2. homogen und farbneutral
  3. 3. Flexibilität in der Anordnung, z.B. Muster und Design, Zellenteilungen, wie beispielsweise definierte örtlich begrenzte Flüssigkristallanzeigen, beispielsweise Blinds bzw. Segmente und/oder Schriftzüge
  4. 4. Stromversorgung liegt vorzugsweise im Niederspannungsbereich
  5. 5. kombinierte Privacy- und Sonnenschutzfunktion
  6. 6.  
In contrast, the object of the present invention is to provide a multi-layer glazing that has an electrically switchable, ie dimmable, sun and privacy screen. Further essential features of the glazing should be:
  1. 1. Failsafe (fail-safe when de-energized)
  2. 2. homogeneous and neutral in color
  3. 3. Flexibility in the arrangement, for example pattern and design, cell divisions, such as defined, locally limited liquid crystal displays, for example blinds or segments and / or lettering
  4. 4. Power supply is preferably in the low voltage range
  5. 5. Combined privacy and sun protection function
  6. 6.

Der Begriff der Verscheibung bezieht sich nachfolgend insbesondere auf Verscheibungen von Flugzeugen, wird aber auch synonym für Verscheibungen von Immobilien im Innen- und Außenbereich, allgemein im Bereich der Fahrzeugtechnik, d.h. für Scheiben von Schiffen, Zügen und Kraftfahrzeugen, insbesondere PKW, LKW und Busse eingesetzt. Die erfindungsgemäßen Verscheibungen können gleichermaßen auch als Sonnenblende in den Kraftfahrzeugen eingesetzt werden.The term glazing in the following refers in particular to glazing for aircraft, but is also used synonymously for glazing of real estate indoors and outdoors, generally in the field of vehicle technology, i.e. for windows on ships, trains and motor vehicles, in particular cars, trucks and buses . The glazing according to the invention can also be used as sun visors in motor vehicles.

Ein Problem des Standes der Technik besteht beispielsweise bei Flugzeugverscheibungen im Austausch und/oder der Umrüstung von bekannten elektrochromen oder elektrotropen Verscheibungen, beispielsweise wenn eine Scheibe ausfällt oder beschädigt ist. Hier hat das Bodenpersonal der Maschine höchstens 10 Minuten Zeit um eine Scheibe auszutauschen. Die bekannten Systeme des Standes der Technik sind aufwändig in Hinblick auf Zeit und Kosten.A problem of the state of the art exists for example in the case of aircraft glazing in the exchange and / or retrofitting of known electrochromic or electrotropic glazing, for example if a disc fails or is damaged. The ground staff of the machine has a maximum of 10 minutes to replace a pane. The known systems of the prior art are complex in terms of time and costs.

Die vorgenannte Aufgabe wird in einer ersten Ausführungsform gelöst durch eine mehrschichtige Verscheibung mit elektrisch schaltbaren optischen Eigenschaften, die dadurch gekennzeichnet ist, dass die Verscheibung im spannungslosen Zustand maximale Transluzenz (Transparenz) und minimale Opazität für Licht im sichtbaren Bereich (380 nm bis 780 nm, insbesondere 400 nm bis 750 nm)und im Zustand angelegter Spannung demgegenüber geringere Transluzenz (Transparenz) und/oder höhere Opazität aufweist.The above-mentioned object is achieved in a first embodiment by a multi-layer glazing with electrically switchable optical properties, which is characterized in that the glazing in the de-energized state has maximum translucency (transparency) and minimum opacity for light in the visible range (380 nm to 780 nm, in particular 400 nm to 750 nm) and in the state of applied voltage, on the other hand, has lower translucency (transparency) and / or higher opacity.

Der wesentliche Kern der Erfindung beschreibt somit ein „Failsafe Smartglass Window‟ (insbesondere Solarzellen - batteriebetrieben) und somit eine Austauschlösung gegenüber dem Stand der Technik ohne Änderungen bzw. Wartungen, die an das in einem Flugzeug vorhandenes CAN (Controller Aera Network) angeschlossen werden kann. Die wesentlichen Vorteile der Erfindung gegenüber dem oben definierten Stand der Technik liegen in dessen Flexibilität.

  • • Farbneutralität
  • • Homogenität
  • • Geringer Rand, beispielsweise weniger als 3 mm
  • • Geringes Gewicht
  • • Kleine Schaltgeschwindigkeit, beispielsweise <1 sec
  • • Direkter Anschluss an CAN ohne Zuschaltgerät. Ist kein Anschluss an CAN vorhanden, kann ein Solarbetrieb möglich sein
  • • Glas-Stärke beispielsweise 3 bis 8 mm
  • • Keine Blasenbildung
  • • Langlebigkeit.
The essential core of the invention thus describes a “Failsafe Smartglass Window” (especially solar cells - battery operated) and thus an exchange solution compared to the state of the art without changes or maintenance, which can be connected to the CAN (Controller Aera Network) in an aircraft . The main advantages of the invention over the prior art defined above are its flexibility.
  • • Color neutrality
  • • homogeneity
  • • Small margin, for example less than 3 mm
  • • Light weight
  • • Low switching speed, for example <1 sec
  • • Direct connection to CAN without an additional device. If there is no connection to the CAN, solar operation may be possible
  • • Glass thickness, for example 3 to 8 mm
  • • No blistering
  • • Longevity.

Die Verscheibung kann beispielsweise direkt an die Partition ohne Schaltgerät an die CAN (direkter Kontakt zum Passagier) angeschlossen werden. Die aktive Verscheibung kann daher direkt an den Innenraum Rahmen der Scheibe implementiert werden.The glazing can, for example, be connected directly to the partition without switching device to the CAN (direct contact with the passenger). The active glazing can therefore be implemented directly on the interior frame of the window.

In einer weiteren bevorzugten Ausführungsform der Erfindung umfasst die Verscheibung in einer Version 1 von außen nach innen:

  1. (a) eine Schutzscheibe,
  2. (b) eine erste Flüssigkristallzelle
  3. (c) eine erste Zwischenschicht, die insbesondere eine Klebeschicht umfasst,
  4. (d) gegebenenfalls ein PN Flüssigkristall- und/oder ein PD Flüssigkristall-Element,
  5. (e) eine zweite Zwischenschicht, die auch in Form einer Scheibe ausgebildet sein kann; für den Fall, dass das PN Flüssigkristall- und/oder ein PD Flüssigkristall-Element (d) nicht vorhanden ist, kann die Zwischenschicht (e) gegebenenfalls auch entfallen,
  6. (f) eine zweite Flüssigkristallzelle und
  7. (g) eine Innenscheibe.
In a further preferred embodiment of the invention, the glazing comprises one version 1 from the outside to the inside:
  1. (a) a protective screen,
  2. (b) a first liquid crystal cell
  3. (c) a first intermediate layer, which in particular comprises an adhesive layer,
  4. (d) optionally a PN liquid crystal and / or a PD liquid crystal element,
  5. (e) a second intermediate layer, which can also be designed in the form of a disk; in the event that the PN liquid crystal and / or a PD liquid crystal element (d) is not present, the intermediate layer (e) can optionally also be omitted,
  6. (f) a second liquid crystal cell and
  7. (g) an inner disc.

Hierbei ist zu beachten, dass die Schutzscheibe nicht die äußerste, der Atmosphäre benachbarte Scheibe ist, die den Temperaturen und Witterungseinflüssen, beispielsweise während des Fluges ausgesetzt ist. Wenn die Schicht (d) nicht vorhanden ist, ist nur eine Zwischenschicht erforderlich.It should be noted here that the protective pane is not the outermost pane adjacent to the atmosphere, which is exposed to temperatures and weather influences, for example during a flight. If layer (d) is not present, only an intermediate layer is required.

In einer Version 2 sind gegenüber der Version 1 hier die Schichten (d) und (f) vertauscht, so dass der Sketcher-Eindruck, d.h. die milchig-weiße Trübung im Vordergrund steht.In version 2, layers (d) and (f) are reversed compared to version 1, so that the sketcher impression, i.e. the milky-white cloudiness, is in the foreground.

Bevorzugte Materialien sind für alle Varianten und Versionen in der nachfolgenden Tabelle aufgeführt, die auch Materialien für andere Versionen beschreibt: Übersicht Version 2: (a) Schutzscheibe, beispielsweise aus Kunststoff (insbesondere Polycarbonat oder PMMA ) (c) Klebeverbund, beispielsweise durch EVA, PVB oder OCA Verklebung (e) Klebeverbund wie oben unter (c) (g) Schutzscheibe wie oben unter (a) Preferred materials are listed for all variants and versions in the following table, which also describes materials for other versions: Overview version 2: (a) Protective screen, for example made of plastic (especially polycarbonate or PMMA) (c) Adhesive bond, for example through EVA, PVB or OCA bonding (e) Adhesive bond as above under (c) (g) Protective disk as above under (a)

Die Vorteile der vorliegenden Erfindung liegen in der Flexibilität der Lichttransmission. Zudem wird die Kombination Privacy und Sonnenschutz in Einem ergänzt, vor Allem als Failsafe Lösung. Auch eine optische Flexibilität durch variable Mehrschicht-Kombination ist möglich; siehe beispielsweise den Übergang von der Version 1 auf die Version 2, die gegebenenfalls auch beispielsweise insgesamt 8 Schichten haben könnte.The advantages of the present invention lie in the flexibility of light transmission. In addition, the combination of privacy and sun protection is supplemented in one, especially as a fail-safe solution. Optical flexibility through variable multilayer combinations is also possible; see for example the transition from version 1 to version 2, which could possibly also have a total of 8 layers.

Eine weitere bevorzugte Ausführungsform der erfindungsgemäßen Verscheibung ist dadurch gekennzeichnet, dass die Schutzscheibe (Außenscheibe), die Zwischenscheibe(n) und/oder die Innenscheibe jeweils Mineralglas, insbesondere gehärtetes Glas oder Kunststoffglas, insbesondere Polymethylmethacrylat oder Polycarbonat umfassen können bzw. daraus bestehen. Die vorgenannten Gläser weisen eine überdurchschnittliche Härte und Kratzfestigkeit auf.Another preferred embodiment of the glazing according to the invention is characterized in that the protective pane (outer pane), the intermediate pane (s) and / or the inner pane can each comprise or consist of mineral glass, in particular hardened glass or plastic glass, in particular polymethyl methacrylate or polycarbonate. The aforementioned glasses have an above-average hardness and scratch resistance.

Besonders bevorzugt im Sinne der vorliegenden Erfindung ist eine Verscheibung, die dadurch gekennzeichnet ist, dass das erste und/oder zweite Flüssigkristall-Element eine handelsübliche Flüssigkristallmischung zwischen zwei mit transparenten leitfähigen Oxiden beschichteten Scheiben (Folien) umfasst. Entsprechende Elemente sind beispielsweise von der Fa. Merck im Handel erhältlich.Particularly preferred in the context of the present invention is glazing which is characterized in that the first and / or second liquid crystal element comprises a commercially available liquid crystal mixture between two panes (foils) coated with transparent conductive oxides. Corresponding elements are commercially available from Merck, for example.

Eine Verscheibung im Sinne der vorliegenden Erfindung ist dann besonders bevorzugt, wenn diese dadurch gekennzeichnet ist, dass auch das PN Flüssigkristall- und/oder das PD Flüssigkristall-Element sofern vorhanden im stromlosen Zustand farblos transparent sind. Der Vorteil liegt in der Ausfallsicherheit. Fällt der Strom aus, können Passagiere nach außen sehen, wenn beispielsweise eine Turbine brennt.Glazing in the sense of the present invention is particularly preferred if it is characterized in that the PN liquid crystal and / or the PD liquid crystal element, if present, are colorlessly transparent in the currentless state. The advantage lies in the reliability. If the power fails, passengers can see outside if, for example, a turbine is burning.

Besonders bevorzugt im Sinne der vorliegenden Erfindung ist eine Verscheibung wie oben definiert, die dadurch gekennzeichnet ist, dass das erste und zweite Flüssigkristallelement eine erste und eine zweite Polarisationsschicht bilden, die in Abhängigkeit von der angelegten Spannung die Transluzenz schalt. Der Vorteil liegt auch hier in der Ausfallsicherheit. Fällt der Strom aus, können Passagiere nach außen sehen, wenn beispielsweise eine Turbine brennt. Sonst würde das bei Anwesenheit eines PN Flüssigkristall-Elements keinen Vorteil bilden. Beide Systeme müssen ausfallsicher sein.Particularly preferred within the meaning of the present invention is glazing as defined above, which is characterized in that the first and second liquid crystal elements form a first and a second polarization layer which switches the translucency as a function of the applied voltage. The advantage here also lies in the reliability. If the power fails, passengers can see outside if, for example, a turbine is burning. Otherwise there would be no advantage in the presence of a PN liquid crystal element. Both systems must be fail-safe.

Mit Hilfe der vorliegenden Erfindung gelingt die Bereitstellung von Verscheibungen, die dadurch gekennzeichnet sind, dass der Hazewert (Trübung), bestimmt mit einem Hazemeter NDH 2000 bei Normlichtart D65 im spannungslosen Zustand im Bereich des sichtbaren Lichts weniger als 1%, insbesondere weniger als 0,5% beträgt. Damit ist die Verscheibung im stromlosen zustand praktisch klar durchsichtig. Im gleichen Spannungszustand kann die Transmission ebenfalls mit einem Hazemeter NDH 2000 bei Normlichtart D65 von wenigstens 50 %, insbesondere wenigstens 60% vermessen werden. Damit ist der erfindungsgemäße Schichtaufbau unter üblichen Bedingungen mit bloßem Auge praktisch nicht sichtbar. Der Haze und die Transmission werden wie im Stand der Technik üblich mit der Gesamtverscheibung unter Einsatz der Normlichtart D65 (siehe hierzu WIKIPEDIA, Stichwort „Normlichtart“, Abrufdatum 28.06.2019) gemessen.With the help of the present invention, it is possible to provide glazing, which is characterized in that the haze value (turbidity), determined with a Hazemeter NDH 2000 with standard illuminant D65 in the de-energized state in the range of visible light is less than 1%, in particular less than 0, 5%. This means that the glazing is practically clear when the power is off. In the same voltage state, the transmission can also be measured with a Hazemeter NDH 2000 with standard light type D65 of at least 50%, in particular at least 60%. The layer structure according to the invention is therefore practically invisible to the naked eye under customary conditions. The haze and the transmission are measured as usual in the state of the art with the entire glazing using the standard illuminant D65 (see WIKIPEDIA, keyword "standard illuminant", retrieval date 28.06.2019).

Bei angelegter Spannung kann erfindungsgemäß ein Hazewert mit dem Hazemeter NDH 2000 bei Normlichtart D65 von mehr als 70 %, insbesondere mehr als 80 % und/ oder eine Transmission im Spannungszustand mit dem Hazemeter NDH 2000 bei Normlichtart D65 von bis zu 20 %, insbesondere bis zu 10 % gemessen werden.When voltage is applied, according to the invention, a hazard value with the Hazemeter NDH 2000 with standard light type D65 of more than 70%, in particular more than 80% and / or a transmission in the voltage state with the Hazemeter NDH 2000 with standard light type D65 of up to 20%, in particular up to 10% can be measured.

Gegebenenfalls kann die Verscheibung segmentierte Schaltbereiche der Zellen zur lokal begrenzten hell-dunkel und/oder transparent-opak Steuerung umfassen. Die Stromversorgung und Ansteuerung der Verscheibung oder einzelner Zellen erfolgt insbesondere durch externe Anschlüsse. Zum Beispiel steuert eine flache flexible Kontrolleinheit (PCB) mit dem CAN oder einer Batterie, die beispielsweise durch Solarzellen die Spannung speichert, die die einzelnen (Spannungs-) Schaltzustände) erlaubt. Damit ist eine autonome Funktion und Steuerung der Eigenschaften der verscheibung und einzelner Zellen möglich.If necessary, the glazing can comprise segmented switching areas of the cells for locally delimited light-dark and / or transparent-opaque control. The power supply and control of the glazing or individual cells takes place in particular through external connections. For example, a flat, flexible control unit (PCB) controls with the CAN or a battery that stores the voltage, for example through solar cells, which allows the individual (voltage) switching states. This enables an autonomous function and control of the properties of the glazing and individual cells.

Eine erfindungsgemäße Verscheibung kann weiterhin eine separate oder integrierte Bildschirm-/Displayeinrichtung aufweisen, da es erfindungsgemäß möglich ist, aktive oder passive Matrizen zu steuern, mit denen beispielsweise die Geschwindigkeit, Uhrzeit, Flughöhen, Zeichen (Gurt) dargestellt werden können. In gleicher Weise lassen sich auch (kleine) OLED Displays einbetten.A glazing according to the invention can also have a separate or integrated screen / display device, since according to the invention it is possible to control active or passive matrices with which, for example, the speed, time, altitude, characters (belt) can be displayed. (Small) OLED displays can also be embedded in the same way.

In einer weiteren bevorzugten Ausführungsform der Erfindung umfasst die Verscheibung eine in diese integrierte, flexible, gegebenenfalls eingebettete solarzellenbetriebene Batterie beispielsweise mit Touch-Funktion in der Bedieneinheit. Die Bedienung erfolgt dann durch eine Touchmembran. Diese Touchelemente werden über die PCB bzw. Steuerelemente als ON , OFF bzw. Schaltbefehle in die Funktion umgesetzt. Der User kann direkt an der Verscheibung, beispielsweise am Fenster über die Berührung der maskierten Touchbereiche die Verscheibung bedienen.In a further preferred embodiment of the invention, the glazing comprises a flexible, possibly embedded solar cell-operated battery, for example with a touch function in the operating unit, integrated into it. Operation is then carried out through a touch membrane. These touch elements are implemented as ON, OFF or switching commands via the PCB or control elements. The user can operate the glazing directly on the glazing, for example on the window by touching the masked touch areas.
