Die Erfindung ist besonders vorteilhaft wenn die Verglasung eine Wärmestrahlung reflektierende leitfähige Beschichtung mit einem g-Wert < 75% enthält. «g-Wert» bedeutet nach ISO 9050:2003-08 Gesamttransmissionsgrad an Sonnenenergie durch das erfindungsgemäße Laminat einer Verglasung.

Es folgt die Erläuterung der Erfindung anhand der Figuren nach Aufbau und gegebenenfalls auch nach Wirkweise der dargestellten Erfindung. There follows the explanation of the invention with reference to the figures according to the structure and, where appropriate, also by mode of action of the illustrated invention.
Figuren 1 bis 3 zeigen eine Draufsicht auf einen Querschnitt und einen Längsschnitt durch ein Ausführungsbeispiel einer erfindungsgemäßen Verglasung (I). Auf eine Windschutzscheibe (5) eines Fahrzeugs war eine elektrisch leitfähige transparente wärmereflektierende Beschichtung (1 ) mit einer transparenten leitfähigen Silberschicht aufgebracht worden. Die Verglasung (I) hatte einen g-Wert von 70 %. Die Gesamtschichtdicke der Beschichtung (1 ) betrug 200 nm. Die Fläche der Verglasung (I) mit der elektrisch leitfähigen Beschichtung (1 ) betrug 5000 cm2. In der elektrisch leitfähigen Beschichtung (1 ) waren spiralförmige Isolationsbereiche (6) mit einer Breite von 0,1 mm vorhanden. Die Isolationsbereiche (6) trennten zwei ineinander liegende spiralförmige Elektroden (2a)(3a) elektrisch voneinander. Die Leiterbahnen der Elektroden (2a)(3a) hatten eine Breite von 1 mm. Durch weitere Isolationsbereiche (6) wurden Leitungsführungen (2b)(3b) und Kontaktbereiche (2c)(3c) von der elektrisch leitfähigen Schichtstruktur (1 ) elektrisch getrennt. Im Randbereich (4) der Glasscheibe (1 ) waren die Kontaktbereiche (2c)(3c) mit Flachleitern (10) verbunden. Die Elektroden (2a)(3a), Leitungsführungen (2b)(3b) und Kontaktbereiche (2c)(3c) waren transparent und für den Betrachter nicht oder kaum sichtbar. Die Elektroden (2a)(3a) wurden mit einer Wechselspannung von 2 MHz angeregt und ein elektrisches Wechselfeld wurde erzeugt. In Abhängigkeit von der Breite der Isolationsbereiche (6), der Form der Elektroden (2a)(3a), der Schichtdicke der Elektroden (2a)(3a), der Glasscheibe (5) und der verwendeten Materialien wurde eine Impedanz zwischen den Elektroden gemessen. Näherte sich ein Körper, beispielsweise ein menschlicher Finger, den Elektroden (2a)(3a) und / oder der Glasscheibe (5), änderte sich das elektrische Feld und in der Folge die Impedanz zwischen den Elektroden (2a)(3a). Die Änderung der Impedanz wurde messtechnisch erfasst. Das elektrische Wechselfeld durchdrang die Glasscheibe (5). Auf der der elektrisch leitfähigen Schichtstruktur abgewandten Seite der Glasscheibe (5) wurde im Bereich der Elektroden (2a)(3a) durch das Wechselfeld eine Schaltfläche (16) mit einer Fläche von 9 cm2 erzeugt. Zur Vermeidung von ungewollten Detektionen von Körpern außerhalb der Schaltfläche (16) war die elektrisch leitfähige Beschichtung (1 ) außerhalb des Elektrodenbereichs (2a)(3a) über einen weiteren Kontaktbereich (3c) auf Massepotential gelegt. Zur Erhöhung der Sensitivität der Anordnung wurden über weitere Isolationsbereiche (6) Zwischenbereiche (7) zwischen der elektrisch leitfähigen Beschichtung (1 ) und den Elektroden (2a)(2b) von der elektrisch leitfähigen Beschichtung (1 ) elektrisch isoliert. Die Scheibe (5) mit der elektrisch leitfähigen Beschichtung (1 ), den Isolationsbereichen (6) und Teilen des Flachleiters (10) waren über eine Haftschicht (9) mit Polyvinylbutyral und lumineszierenden Partikeln mit einer Deckscheibe (8) verbunden. Die Deckscheibe (8) war im Fahrzeug außenliegend. Die Schaltfläche (16) war zum Fahrgastraum hin ausgerichtet. Die Schaltfläche (16) konnte vom Innenraum des Fahrzeugs aus bedient werden. Die Schaltfläche (16) wurde über Lumineszenz im Polyvinylbutyral über eine dynamische Projektion (Head-up Display, nicht dargestellt) im Fahrzeug dynamisch markiert. Figures 1 to 3 show a plan view of a cross section and a longitudinal section through an embodiment of a glazing (I) according to the invention. Onto a windshield (5) of a vehicle, an electrically conductive transparent heat reflective coating (1) having a transparent conductive silver layer was applied. The glazing (I) had a g-value of 70%. The total layer thickness of the coating (1) was 200 nm. The area of the glazing (I) with the electrically conductive coating (1) was 5000 cm 2 . In the electrically conductive coating (1) spiral insulation regions (6) were present with a width of 0.1 mm. The isolation regions (6) electrically separated two nested helical electrodes (2a) (3a). The conductor tracks of the electrodes (2a) (3a) had a width of 1 mm. Through further isolation regions (6), cable guides (2b) (3b) and contact regions (2c) (3c) were electrically separated from the electrically conductive layer structure (1). In the edge region (4) of the glass pane (1), the contact regions (2c) (3c) were connected to flat conductors (10). The electrodes (2a) (3a), line guides (2b) (3b) and contact areas (2c) (3c) were transparent and not or hardly visible to the viewer. The electrodes (2a) (3a) were excited with an alternating voltage of 2 MHz and an alternating electric field was generated. Depending on the width of the isolation regions (6), the shape of the electrodes (2a) (3a), the layer thickness of the electrodes (2a) (3a), the glass sheet (5) and the materials used, an impedance between the electrodes was measured. When a body, for example a human finger, approaches the electrodes (2a) (3a) and / or the glass pane (5), the electric field changed and, as a consequence, the impedance between the electrodes (2a) (3a). The change in impedance was measured. The alternating electric field penetrated the glass pane (5). On the side of the glass pane (5) facing away from the electrically conductive layer structure, a button (16) having an area of 9 cm 2 was produced in the region of the electrodes (2a) (3a) by the alternating field. To avoid unwanted detections of bodies Outside the button (16), the electrically conductive coating (1) outside the electrode region (2a) (3a) was grounded via a further contact region (3c). To increase the sensitivity of the arrangement, intermediate regions (7) between the electrically conductive coating (1) and the electrodes (2a) (2b) were electrically insulated from the electrically conductive coating (1) via further insulation regions (6). The disk (5) with the electrically conductive coating (1), the insulation regions (6) and parts of the flat conductor (10) were connected via an adhesive layer (9) with polyvinyl butyral and luminescent particles with a cover plate (8). The cover disc (8) was outboard in the vehicle. The button (16) was aligned to the passenger compartment. The button (16) could be operated from the interior of the vehicle. The button (16) was dynamically marked via luminescence in the polyvinyl butyral via a dynamic projection (head-up display, not shown) in the vehicle.
Es war für den Fachmann nicht vorhersehbar, dass auf einfache Weise eine transparente Schaltfläche (16) aus Bereichen einer wärmereflektierenden und beheizbaren Schicht (1 ) einer Windschutzscheibe gebildet werden konnte, die zur Ansteuerung von Funktionen des Fahrzeugs genutzt werden kann. It was unforeseeable for a person skilled in the art that a transparent button (16) could be formed in a simple manner from regions of a heat-reflecting and heatable layer (1) of a windshield that can be used to control functions of the vehicle.
Figur 4 zeigt einen alternativen Querschnitt mit schematisierter Verschaltung einer erfindungsgemäßen aktiven Verglasung (I) gemäß dem Schnitt A-A der Fig. 1 . Die Verglasung (I) enthielt zwischen den Elektrodenstrukturen (2a)(3a) und einer zusätzlichen weiteren elektrisch leitfähigen Schicht (14) eine elektrochrome Schichtstruktur (15). Bei Anlegen einer elektrischen Gleichspannung über einen Signalstromkreis zwischen den Elektrodenstrukturen (2a)(3a) und der weiteren elektrisch leitfähigen Schicht (14) konnte der Lichttransmissionsgrad der elektrochromen Schichtstruktur (15) im Anzeigebereich (16) auf einer Fläche von 9 cm2 eingestellt werden. Zur Ansteuerung des Anzeigebereichs (16) enthielt der Signalstromkreis einen Schalter (19) der mit der Versorgungs- und Auswerteelektronik (13) verbunden war. Durch Anlegen einer elektrischen Gleichspannung über einen Leistungsstromkreis zwischen der elektrisch leitfähigen Schichtstruktur (1 ) und der weiteren elektrisch leitfähige Beschichtung (14) konnte auch der Transmissionsgrad der aktiven Verglasung (I) auf einer Fläche von etwa 4990 cm2 eingestellt werden. Der Leistungsstromkreis (12) enthielt ebenfalls mindestens einen Schalter (19), der ebenfalls mit der Versorgungs- und Auswerteelektronik (13) verbunden war. Durch die unabhängige Schaltmöglichkeit von Anzeigebereich (16) und dem übrigen Bereich der aktiven Verglasung (I) konnte zuerst die schnell reagierende Anzeigefläche (16) geschaltet werden und danach die übrige Fläche der aktiven Verglasung (I). Die Elektroden (2a)(3a) wurden weiter zur Ausbildung des elektrischen Wechselfeldes einer Schaltfläche (16) genutzt, sodass eine kombinierte Schalt- und Anzeigefläche (16) vorhanden war. Zusätzlich wurden die Elektroden (2a)(3a) mit einer Wechselspannung von 2 MHz angeregt, um ein elektrisches Wechselfeld für die Schaltfläche (16) bereitzustellen. Zur Messung der Impedanz zwischen den Elektrodenstrukturen (2a)(2b) wurden die Kontaktbereiche (2c)(3c) über einen Signalstromkreis (1 1 ) mit der Versorgungs- und Auswerteelektronik (13) verbunden. Ein Hochpass im Signalstromkreis (1 1 ) trennte die Wechselspannungen und die Gleichspannungen. FIG. 4 shows an alternative cross-section with schematic interconnection of an active glazing (I) according to the invention according to section AA of FIG. 1. The glazing (I) contained an electrochromic layer structure (15) between the electrode structures (2a) (3a) and an additional further electrically conductive layer (14). When a direct electrical voltage was applied via a signal circuit between the electrode structures (2a) (3a) and the further electrically conductive layer (14), the light transmittance of the electrochromic layer structure (15) in the display area (16) could be adjusted to an area of 9 cm 2 . To control the display area (16), the signal circuit contained a switch (19) which was connected to the supply and evaluation electronics (13). By applying a direct electrical voltage via a power circuit between the electrically conductive layer structure (1) and the further electrically conductive coating (14), the transmittance of the active glazing (I) on an area of about 4990 cm 2 could be adjusted. The power circuit (12) also contained at least one switch (19), which was also connected to the supply and evaluation electronics (13). By the independent Switching possibility of display area (16) and the remaining area of the active glazing (I) was first the fast-reacting display surface (16) are switched and then the remaining surface of the active glazing (I). The electrodes (2a) (3a) were further used to form the alternating electric field of a button (16), so that a combined switching and display surface (16) was present. In addition, the electrodes (2a) (3a) were excited with an AC voltage of 2 MHz to provide an AC electric field for the button (16). For measuring the impedance between the electrode structures (2a) (2b), the contact areas (2c) (3c) were connected to the supply and evaluation electronics (13) via a signal circuit (11). A high pass in the signal circuit (1 1) separated the alternating voltages and the DC voltages.
Bei Detektion eines Körpers im elektrischen Wechselfeld des Schaltbereichs (16) wurde beispielsweise ein Schalter (19) für den Anzeigebereich geschlossen und die aktive Schichtstruktur (15) änderte zuerst im Anzeigebereich (16) ihren Zustand. Durch die geringe Fläche von 9 cm2 änderte die Schichtstruktur (15) im Anzeigebereich (16) innerhalb von 10 ms bis 10 s den Transmissionsgrad. Der Bediener wurde damit innerhalb kurzer Zeit über die Detektion informiert. Die Änderung des Schaltzustandes der aktiven Verglasung mit einer Fläche von 4990 cm2 erfolgte danach innerhalb einer Zeitspanne von 20 s bis 3600 s. Upon detection of a body in the alternating electric field of the switching area (16), for example, a switch (19) for the display area was closed and the active layer structure (15) first changed its state in the display area (16). Due to the small area of 9 cm 2 , the layer structure (15) in the display area (16) changed the transmittance within 10 ms to 10 s. The operator was informed about the detection within a short time. The change in the switching state of the active glazing with an area of 4990 cm 2 was then carried out within a period of 20 s to 3600 s.
Es war für den Fachmann nicht vorhersehbar, dass auf einfache Weise eine Schalt- / und schnell reagierende Anzeigefläche (16) in bestehende elektrisch leitfähige Beschichtungen (1 ) integriert werden konnte und damit eine elektrochrome Verglasung (I) bereitgestellt werden konnte, die einem Bediener innerhalb kurzer Zeit den Schaltzustand der elektrochromen Verglasung (I) anzeigte. It was not foreseeable for a person skilled in the art that a switchable and rapidly responding display surface (16) could easily be integrated into existing electrically conductive coatings (1) and thus an electrochromic glazing (I) could be provided to an operator within a short time the switching state of the electrochromic glazing (I) displayed.
Fig. 5 zeigt eine weitere Ausgestaltung der erfindungsgemäßen aktiven Verglasung gemäß dem Ausführungsbeispiel der Fig. 4. Der Unterschied zu der Verglasung nach Fig. 4 liegt darin, dass Isolationsbereiche (6) zusätzlich in der aktiven Schichtstruktur (15) eingebracht waren. Durch diese erfindungsgemäße Ausgestaltung konnte die Empfindlichkeit des Schaltbereichs (16) und / oder die Reaktionszeit des Anzeigebereichs (16) weiter erhöht werden. Fig. 6 zeigt Ausgestaltungen der erfindungsgemäßen Wärmeschutzverglasung (I) mit einer Schaltfläche (16) oder eine Ausgestaltung als aktive elektrochrome Verglasung mit Schalt- / und Anzeigefläche (16). Die elektrisch leitfähige Schichtstruktur (1 ) war im Randbereich (4) der Scheibe (5) rahmenförmig randentschichtet und lag auf Massepotential. Die aktive Verglasung (I) war über schaltbare Leistungsstromkreise (12) und schaltbare Signalstromkreise (1 1 ) mit der Versorgungs- und Auswerteelektronik (13) verbunden. FIG. 5 shows a further embodiment of the active glazing according to the invention according to the exemplary embodiment of FIG. 4. The difference from the glazing according to FIG. 4 lies in the fact that insulation regions (6) were additionally introduced into the active layer structure (15). By means of this embodiment according to the invention, the sensitivity of the switching region (16) and / or the reaction time of the display region (16) could be further increased. FIG. 6 shows embodiments of the inventive heat-insulating glazing (I) with a button (16) or a configuration as an active electrochromic glazing with switching and display surface (16).
