Abstract

The front plate (6) for an optical character display comprises a transparent sheet which is coated with an opaque layer (8) except for selected zones (10, 11) corresponding to the characters to be displayed. These zones (10, 11) are coated with a translucent layer (9), which pref. extends over the entire front surface of the front plate (6). The opaque layer (8) is pref. also applied to the front surface of the front plate (6), between the latter and the translucent layer (9) and the front plate (6) itself is pref. made from plastics. A light source (3) is positioned behind each of the character zones (10, 11).

Description

Anzeigofrontplatte für die optische Anzeige von Zeichen Front display panel for the visual display of characters

Die Erfindung bezieht sich auf eine Anzeigefrontplatte für die optische Anzeige von Zeichen mit einer Grunddplatte aus lichtdurchlässigem Material, die von einer lichtundurchlässigen Schicht überzogen ist, welche den anzuzeigenden Zeichen e-ntsprechend ausgespart ist.The invention relates to an optical display panel Display of characters with a base plate made of translucent material that is covered by an opaque layer, which the characters to be displayed e is correspondingly recessed.

Es sind Anzeigefrontplatten dieser Ant bekannt, bei denen die Grundplatte aus Acrylglas besteht, welche auf ihrer Rückseite, d.h. auf der der Lichtquelle bzw. den Lichtquellen zugewandten Seite dunkel bedruckt ist. Die Zeichen sind negativ ausgespart, so daß bei einer Beleuchtung der Platte die Zeichen sichtbar werden. Wegen der dunklen Färbung der lichtundurchlässigen Schicht sind die Zeichen dann, wenn die Platte nicht belenchtetist, praktisch nicht sichtbar.There are display front panels of this Ant known in which the base plate consists of acrylic glass, which is on its back, i.e. on that of the light source or the side facing the light sources is printed dark. The signs are negative recessed so that the characters are visible when the plate is illuminated. Because of the dark color of the opaque layer, the characters are then if the plate is not illuminated, practically invisible.

Nachteilig ist bei den bekannten Anzeigefrontplatten einerseits, daß die lichtundurchlässige Schicht immer in dunkler Farbe gehalten werden nuß, daß also andere Farbgebungen nicht möglich sind, und daß andererseits zwischen der der @ichtquelle bzw.The disadvantage of the known front display panels on the one hand is that the opaque layer must always be kept in a dark color so other colors are not possible, and that on the other hand between the @light source or

den Lichtquellen zugewandten Seite und Begrenzungsflächen für den Lichtstron eine lichtdichte Montage vorgenommen werden @uß.the side facing the light sources and boundary surfaces for the Lichtstron a light-tight assembly can be carried out.

Der Erfindung liegt die Aufgabe zugrunde, eine Anzeigefrontplatte der eingangs genannten Art zu schaffen, bei der eine beliebige Farbgebung möglich und ein ebsolut lichtdichter Übergang nu Begrenzungsflächen für das Licht nicht erforderlich ist.The invention is based on the object of a front display panel to create of the type mentioned, in which any color is possible and an absolutely light-tight transition nu boundary surfaces for the light is required.

Diese Aufgabe ist erfindungsgemäß gelöst durch eine transluzente Schicht, die die Anzeigefrontplatte mindesteiis im Bereich der anzuzeigenden Zeichen vollständie überdeckt. Bei der erfindungsgemäßen Anzeigefrontplatte ist es möglich, scwohlder lichtun- durchlässigen Schicht als auch der transluzenten Schicht eine beliebige Farbe zu geben. Wegen der Verwendung der transluzenten Schicht ist ein absolut lichtdichter Übergang von der der Lichtquelle bzw. den Licktquellen zugewandten Seite der Anzeigefrontplatte auf die Begrenzungsflächen für den Lichtstrom nicht erforderlich.According to the invention, this object is achieved by a translucent layer, which complete the display front panel at least in the area of the characters to be displayed covered. In the case of the front display panel according to the invention, it is possible to light- permeable layer as well as the translucent layer to give any color. Because of the use of the translucent layer it is an absolutely light-tight transition from the light source or the light sources facing side of the display front plate on the boundary surfaces for the luminous flux not mandatory.

Die Erfindung ist nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläuter .The invention is illustrated below with reference to one in the drawing Explanation of the embodiment in more detail.

In der Zeiebnang ist ein Gehäuse 1 aus lichtundurchlässigem Material, z.B. lichtundurchlässigem Eunststoff,dangestellt, das Begrenzungsflächen 2 für den Lichtstrom einer Lichtquelle 3 und Begrenzungsflächen 4 für den Lichtstrom einer Lichtquelle 5 aufwsist. Auf den freien Enden der Begrenzungsflächen 2 und 4 sitzt eine Anseigefrontplatte 6, die aus einer Grundplatte 7 aus Aepylglas und zwei Schichten 8 und 9, die auf der Grundplatte 7 aufgebracht sind, besteht. Die Schicht 8 ist dabei eine lichtundurchlässige Schiebt mit beliebiger Farbe, die an den Stellen 10 und 11 den anzuzeigenden Schrift- oder Bildzeichen entsprechend ausgespart ist. Die lichtundurchlässige Scbicht 8 liegt zwischen den Grundplatte 7 und der transluzenten, also lieht däßpfenden aber hindurchlassenden Schicht 9, welche die lichtundurchlässige Scbicht 8 im Bereich der Aussparungen 10 und 11, also der ansuzeigenden Zeichen, vollständig überdeckt.In the Zeiebnang is a housing 1 made of opaque material, E.g. opaque plastic, placed, the boundary surfaces 2 for the Luminous flux of a light source 3 and boundary surfaces 4 for the luminous flux of a Light source 5 upsist. Sitting on the free ends of the boundary surfaces 2 and 4 a front plate 6, which consists of a base plate 7 made of Aepylglas and two layers 8 and 9, which are applied to the base plate 7, consists. Layer 8 is doing an opaque pushes with any color on the spots 10 and 11 is cut out according to the characters or symbols to be displayed. The opaque layer 8 lies between the base plate 7 and the translucent, thus lent dampening but permeable layer 9, which is the opaque Scbicht 8 in the area of the recesses 10 and 11, i.e. the signs to be displayed, completely covered.

Die transluzente Schicht 9 kann ebenfalls jede beliebige Farbe haben und besteht aus einem geeigneten Lack.The translucent layer 9 can also have any color and consists of a suitable varnish.

Bei ausgeschalteten Lichtquellen 3 und 5 sind die Aussparungen 10 und 11 und damit die anzuzeigenden Zeichen unsichtbar, da sie durch die transluzente Schicht 9 abgedeckt sind. Sie werden sichttar, wenn die Lichtquellen 3 und 5 eingeschaltet werden.When the light sources 3 and 5 are switched off, the recesses 10 are and 11 and thus the characters to be displayed are invisible because they are made through the translucent Layer 9 are covered. They become visible when light sources 3 and 5 are switched on will.

Wird nur eine dieser Lichtquellen eingeschalte, so wird nur das zugeordnete Zeichen sichtbar.If only one of these light sources is switched on, only the assigned one is activated Characters visible.

Die transluzente Schicht 9 ermöglicht es, daß ein absolut lichtdichter Übergeng von den begren@@@ngsflächen 2 und 4 auf die Anze@gefrentplatte 6 nicht erforderlich ist.The translucent layer 9 makes it possible that an absolutely light-tight Do not transfer from the limited areas 2 and 4 to the display panel 6 is required.

Bei dem Ausführungsbeispiel ist-die lichtundurchlassige Schicht 8 und die transluzente Schicht 9 auf der Außenseite der Grundplatte 7, auf der der Lichtstrom der Lichtquellen 3 und 5 austritt, angeordnet. Im Rahmen der Erfindung ist aber auch eine Anordnung auf der Innenseite möglich.In the exemplary embodiment, the opaque layer is 8 and the translucent layer 9 on the outside of the base plate 7 on which the Luminous flux of the light sources 3 and 5 exits, arranged. Within the scope of the invention however, an arrangement on the inside is also possible.
