In response to the receipt of the control signal s1, the switch control unit 12 supplies the switch 13 with a control signal s2 which switches this through, so that the switching foil 4 is supplied with the alternating voltage required by it. Due to this power supply, the switching foil 4 is brought into the switched-on state from the switched-off state, in which it is largely non-transparent and, for example, gray-colored, in which it is transparent, so that the information signals shown on the display 2 for a front of the display device 1 positioned observer are visible. If the power supply is removed from the switching foil, the switching foil 4 again becomes largely non-transparent and changes to a translucent state in which its light transmission is reduced by, for example, up to 90%.
- the display 2 is covered by the switching film. This will prevent it from turning off very much dark or black appearing display, whose very dark or black color is often perceived as disturbing, is visible. Instead, the viewer sees through the second glass pane 5 only the color of the largely non-transparent switching foil 4, which is gray, for example, and preferably at least approximately coincides with the color of a side wall of a room adjacent to the display device.
- the switching foil 4 Due to the fact that the switching foil 4 is not completely opaque in its off state, a gap is provided between the switching foil 4 and the display 2, in which the first glass pane 3 is arranged.

- the second glass pane 4 is preferably frosted to prevent light reflections.
- the control unit 8 provides the switch control unit 12 with the control signal s1 for switching on the switching foil 4 when an information signal is to be displayed on the display 2, and provides the switch control unit 12 with a control signal for switching off the switching foil 4 when the display of the information signal to be ended on the display 2.
- the switch control unit can provide the switch control signals s2 for the switch 13 immediately after receiving the control signal s1 supplied thereto.
- the switch control unit 12 may also provide the switch control signals s2 for the switch 13 in such a way that the switching foil is dimmed, ie the light transmittance of the switching foil 4 is slowly increased when it is switched on and slowly reduced when it is switched off.
- a switchover between the two aforementioned embodiments can be carried out by means of the operating unit 9.
- FIG. 2 shows sketches for illustrating different operating positions of a display device according to the invention.
- FIG. 2a the display device 1 is inserted into a recess 15 of a side wall 14 of a room.

Das Display 2 weist eine Vorderseite 2a und eine Rückseite 2b auf. Die erste Glasscheibe 3 weist eine Vorderseite 3a und eine Rückseite 3b auf. Die Schaltfolie 4 weist eine Vorderseite 4a und eine Rückseite 4b auf. Die zweite Glasscheibe 5 weist eine Vorderseite 5a und eine Rückseite 5b auf.The
Die erste Glasscheibe 3 ist mit ihrer Rückseite 3b auf der Vorderseite 2a des Displays 2 angeordnet. Die Schaltfolie 4 ist mit ihrer Rückseite 4b auf der Vorderseite 3a der ersten Glasscheibe 3 angeordnet.

Die Wiedergabe der Informationssignale auf dem Display 2 wird von einer Steuereinheit 8 gesteuert. Diese Steuereinheit 8 kann wie in der

Das Netzteil 11 ist zur Spannungsversorgung der Schaltfolie 4 vorgesehen und mit dieser über einen Schalter 13 verbunden, bei dem es sich um einen elektronischen Schalter oder einen elektromechanischen Schalter handelt. Mittels des Netzteils 11 wird die von der Wechselspannungsquelle 10 bereitgestellte Wechselspannung in die von der Schaltfolie 4 benötigte Wechselspannung umgewandelt, die in Abhängigkeit von der jeweils verwendeten Schaltfolie im Bereich zwischen 12 V und der von der Wechselspannungsquelle 10 bereitgestellten Wechselspannung liegt.The
Zur Steuerung des Schalters 13 ist eine Schaltersteuereinheit 12 vorgesehen, welcher von der Steuereinheit 8 ein Steuersignal s1 zugeführt wird, wenn die Darstellung der Informationssignale auf dem Display 2 beginnen soll. Als Reaktion auf den Empfang des Steuersignals s1 führt die Schaltersteuereinheit 12 dem Schalter 13 ein diesen durchschaltendes Steuersignal s2 zu, so dass die Schaltfolie 4 mit der von ihr benötigten Wechselspannung versorgt wird. Die Schaltfolie 4 wird aufgrund dieser Spannungsversorgung vom ausgeschalteten Zustand, in dem sie weitgehend intransparent ist und beispielsweise eine Graufärbung aufweist, in den eingeschalteten Zustand gebracht, in welchem sie transparent ist, so dass die auf dem Display 2 dargestellten Informationssignale für einen vor der Displayvorrichtung 1 positionierten Betrachters sichtbar sind. Wird der Schaltfolie die Spannungsversorgung wieder genommen, dann wird die Schaltfolie 4 wieder weitgehend intransparent und geht in einen transluzenten Zustand über, in welchem ihre Lichtdurchlässigkeit um beispielsweise bis zu 90% reduziert ist.For controlling the
In diesem ausgeschalteten Zustand der Schaltfolie 4 wird das Display 2 von der Schaltfolie abgedeckt. Dadurch wird verhindert, dass das im ausgeschalteten Zustand sehr dunkel bzw. schwarz erscheinende Display, dessen sehr dunkle bzw. schwarze Farbe oft als störend empfunden wird, sichtbar ist. Stattdessen sieht der Betrachter durch die zweite Glasscheibe 5 lediglich die Farbe der weitgehend intransparenten Schaltfolie 4, die beispielsweise grau ist und vorzugsweise mit der Farbe einer der Displayvorrichtung benachbarten Seitenwand eines Raumes zumindest annähernd übereinstimmt.In this switched-off state of the switching
Aufgrund des Umstandes, dass die Schaltfolie 4 in ihrem ausgeschalteten Zustand nicht vollständig lichtundurchlässig ist, ist zwischen der Schaltfolie 4 und dem Display 2 ein Abstand vorgesehen, in welchem die erste Glasscheibe 3 angeordnet ist. Diese erste Glasscheibe 3, deren Dicke beispielsweise im Bereich zwischen 2 mm und 20 mm liegt, dient zum einen als Abstandshalter zwischen dem Display 2 und der Schaltfolie 4 und hat des Weiteren die Aufgabe, die Stabilität der Schaltfolie 4 zu gewährleisten. Durch diesen Abstand zwischen der Schaltfolie 4 und dem Display 2 erscheint die Schaltfolie 4 in ihrem ausgeschalteten Zustand in ihrer Originalfarbe bzw. ihrem Originalfarbton.Due to the fact that the
Die zweite Glasscheibe 5, deren Dicke beispielsweise zwischen 2 mm und 4 mm liegt, dient ebenfalls zur Gewährleistung der Stabilität der Schaltfolie 4 und damit des gesamten vor dem Display 2 angeordneten Systems, welches aus der Schaltfolie 4 und den die Schaltfolie 4 beidseitig umgebenden Glasscheiben 3 und 5 besteht. Die zweite Glasscheibe 4 ist vorzugsweise mattiert, um Lichtspiegelungen zu verhindern.The
Die Steuereinheit 8 stellt der Schaltersteuereinheit 12 das Steuersignal s1 zur Einschaltung der Schaltfolie 4 dann zur Verfügung, wenn ein Informationssignal auf dem Display 2 angezeigt werden soll, und stellt der Schaltersteuereinheit 12 ein Steuersignal zur Abschaltung der Schaltfolie 4 zur Verfügung, wenn die Anzeige des Informationssignals auf dem Display 2 beendet werden soll.The
Die Schaltersteuereinheit kann gemäß einer Ausführungsform der Erfindung die Schaltersteuersignale s2 für den Schalter 13 unmittelbar nach dem Empfang des ihr zugeführten Steuersignals s1 bereitstellen.The switch control unit according to an embodiment of the invention can provide the switch control signals s2 for the
Gemäß einer anderen Ausführungsform kann die Schaltersteuereinheit 12 die Schaltersteuersignale s2 für den Schalter 13 auch derart zur Verfügung stellen, dass ein Dimmen der Schaltfolie erfolgt, d. h., dass die Lichtdurchlässigkeit der Schaltfolie 4 bei deren Einschalten langsam erhöht und bei deren Ausschalten langsam verringert wird.According to another embodiment, the
Eine Umschaltung zwischen den beiden vorgenannten Ausführungsformen kann mittels der Bedieneinheit 9 durchgeführt werden.A switchover between the two aforementioned embodiments can be carried out by means of the
