Description

Die Erfindung betrifft eine hinterleuchtbare Anzeige, wie sie beispielsweise als Hinweisleuchte in Gebäuden oder Fahrzeugen und insbesondere in Flugzeugen eingesetzt wird.The invention relates to a backlit display, as for example as Indicator light in buildings or vehicles and in particular in aircraft is used.

In einer Vielzahl von Applikationen werden Informationen optisch angezeigt, und zwar über hinterleuchtbare Anzeigeflächen. Derartige hinterleuchtbare Anzeigen finden sich beispielsweise in Flugzeugen zur Anzeige, ob die Toiletten besetzt sind oder nicht oder zur Darstellung der Anschnall- bzw. Nichtraucherzeichen. Die beiden letztgenannten optischen Anzeigen befinden sich unmittelbar oberhalb der Passagiere und sind Bestandteil der sogenannten Passenger-Service-Units (PSU).In a variety of applications, information is visually displayed, via backlit display surfaces. Such backlit Ads can be found, for example, in airplanes to indicate if the toilets are occupied or not or for the presentation of the seat belt or nonsmoker sign. The latter two optical displays are located immediately above the passengers and are part of the so-called passenger service units (PSU).

Hinterleuchtbare Anzeigeflächen bestehen im Regelfall aus einem transparenten Kunststoffmaterial als Blendenelement, auf dessen Vorderseite zur Darstellung der Symbole o.dgl. Anzeigeinformationen gedruckt sind. Über diese bedruckte, Vorderseite ist dann ein lichtundurchlässiger Lack aufgetragen, der im Bereich der Symbole freigelegt ist. Die gesamte Vorderseite des Blendenelements wird dann anschließend mit transluzenter Farbe lackiert. Aufgrund dieses Farbschichtenauftrages sollen die Symbolfelder dann, wenn sie nicht hinterleuchtet sind, für den Betrachter kaum und im Idealfall nicht erkennbar sein.Backlit display surfaces are usually made of a transparent Plastic material as a panel element, on the front side for illustration the symbols or the like Display information is printed. About these printed, front is then applied an opaque paint, the is exposed in the area of symbols. The entire front of the panel element is then subsequently painted with translucent color. by virtue of This color layer order should be the symbol fields if they are not are backlit, for the viewer hardly and ideally not recognizable be.

Allerdings hat sich in der Praxis herausgestellt, dass die wegen der Auftragung der diversen Lackschichten strukturierte Vorderseite der Blendenelemente aufgrund von Schattenwirkungen des Umgebungslichts doch relativ deutlich sichtbar sind, wenn die Symbolfelder nicht hinterleuchtet sind. Dies wird als ästhetisch wenig ansprechend empfunden. However, in practice it has turned out that because of the application the various layers of paint structured front of the aperture elements due Shadow effects of the ambient light but relatively clearly visible are if the symbol fields are not backlit. This is considered aesthetic not very appealing.

Ferner ist es im Stand der Technik bekannt, bedruckte Folien an der Vorderseite der Frontblende von Bedieneinheiten zu verwenden, wobei diese Folien mit Kunststoff hinterspült sind. Die Folien sind mit einer lichtundurchlässigen Farbe bedruckt und lediglich im Bereich des zu hinterleuchtenden Symbolbereiches lichtdurchlässig. Diese Symbolbereiche sollen auch ohne Hinterleuchtung, z. B. bei Tageslicht, optisch wahrnehmbar sein.Further, it is known in the art to use printed films on the front side to use the front panel of control units, these slides are backwashed with plastic. The slides are with an opaque Color printed and only in the area to be backlit symbol area translucent. These symbol areas should also be without backlight, z. B. in daylight, be visually perceptible.

Eine Aufgabe der Erfindung ist es, das optische Erscheinungsbild einer hinterleuchtbaren Anzeige zu verbessern, und zwar insbesondere dann, wenn die Anzeige nicht hinterleuchtet ist.An object of the invention is to improve the visual appearance of a backlit Improve display, especially if the Display is not backlit.

Zur Lösung dieser Aufgabe wird mit der Erfindung eine hinterleuchtbare Anzeige vorgeschlagen, die versehen ist

  • mit einem Blendenelement, das eine Vorderseite mit mindestens einem hinterleuchtbaren Symbolfeld und eine der Vorderseite abgewandte Rückseite aufweist,
  • wobei die Vorderseite von einer mit einer transluzenten Farbe versehenen transparenten Kunststofffolie gebildet ist und
  • wobei die Rückseite durch Hinterspritzen von Kunststoff-Spritzgussmaterial gegen die Kunststofffolie gebildet ist und dieses Kunststoff-Spritzgussmaterial die Kunststofflolie unter Freihaltung des mindestens einen Symbolfeldes lichtundurchlässig bedeckt.
To solve this problem, a backlit display is proposed with the invention, which is provided
  • with an aperture element which has a front side with at least one backlightable symbol field and a rear side facing away from the front side,
  • wherein the front side is formed by a transparent plastic film provided with a translucent color and
  • wherein the back is formed by injection molding of plastic injection molding material against the plastic film and this plastic injection molding material, the plastic film, leaving the at least one symbol field opaque opaque.

Die erfindungsgemäße hinterleuchtbare Anzeige ist zweiteilig aufgebaut und umfasst eine die Vorderseite des Blendenelements bildende transparente Kunststofffolie, die mit lichtundurchlässigem Kunststoff-Spritzgussmaterial hinterspritzt ist. Dieser Herstellungsprozess erfolgt beispielsweise in einem Einsatz-Spritzgusswerkzeug, wobei als Einsatzteil die transparente Kunststorffolie dient. Diese Kunststofffolie ist auf der dem hinterspritzten Kunststoff-Spritzgussmaterial abgewandten (Vorder-) Seite mit transluzenter Farbe versehen. Auf ihrer Rückseite liegt die Kunststofffolie im Bereich des mindestens einen Symbolfeldes frei.The inventive backlit display is constructed in two parts and comprises a transparent forming the front of the diaphragm element Plastic film covered with opaque plastic injection molding material is injected behind. This manufacturing process takes place, for example, in one Insert injection mold, wherein as an insert the transparent Kunststorffolie serves. This plastic film is on the back-injected plastic injection molding material opposite (front) side provided with translucent color. The plastic film lies in the area of at least on the back a symbol field free.

Durch den erfindungsgemäßen Aufbau des Blendenelements weist dieses eine ebene und damit nicht strukturierte Vorderseite auf, die von der Folie gebildet wird. Folien lassen sich technisch wesentlich einfacher und genauer bedrucken als die Oberfläche von nicht blattförmigem Gut. Denn die Drucktechniken können insbesondere mit Vorteil bei flachen Bogen- oder Baumaterialien eingesetzt werden, ohne dass die Druckfarben optisch erkennbar auftragen. Dadurch sind die Symbolfelder im nicht hinterleuchteten Zustand der Anzeige nicht erkennbar. Die transparente Kunststofffolie ist derart dünn, dass über die Symbolfelder von der Rückseite des Blendenelements aus eingespeistes Hinterleuchtungslicht an den Seitenkanten der Kunststofffolie optisch nicht mehr wahrnehmbar austritt. Die durch die transparente Kunststofffolie notwendigerweise gegebene Lichtleitung zur Außenkante der Folie ist also optisch nicht wahrnehmbar.Due to the structure of the diaphragm element according to the invention this has a level and thus unstructured front, formed by the film becomes. Films can be technically much easier and more accurate print as the surface of non-foliated material. Because the printing techniques can particularly advantageously used in flat sheet or building materials without the printing inks being optically recognizable. As a result, the symbol fields are in the non-backlit state of the display not visible. The transparent plastic film is so thin that over the Symbol fields fed from the back of the aperture element Backlit light on the side edges of the plastic film optically not more perceptible exit. The through the transparent plastic film necessarily given light pipe to the outer edge of the film is so optically imperceptible.

In vorteilhafter Weiterbildung der Erfindung ist vorgesehen, dass die Kunststofffolie innerhalb des mindestens einen Symbolfeldes zur Erzeugung eines graphischen Symbols, eines Buchstaben- und/oder Zahlensymbols oder eines anderen Anzeigesymbols bedruckt ist, und zwar insbesondere im Siebdruckverfahren. In diesem Zusammenhang sei angemerkt, dass das Wort "bedrucken" recht allgemein zu verstehen und nicht auf einen Bedruckungsvorgang im eigentlichen Sinne beschränkt ist. Allerdings hat sich herausgestellt, dass ein Siebdruck besonders vorteilhaft im Hinblick auf ein homogenes Druckbild ist.In an advantageous embodiment of the invention, it is provided that the plastic film within the at least one symbol field for generating a graphic symbol, a letter and / or number symbol or a other display symbol is printed, especially in screen printing. In this context it should be noted that the word "printing" is understood quite generally and not on a printing process is limited in the true sense. However, it has turned out that a screen printing particularly advantageous in terms of a homogeneous Print image is.

Je nach der optisch anzuzeigenden Information ist es erforderlich, dass ein Symbolfeld der hinterleuchtbaren Anzeige in unterschiedlichen Farben hinterleuchtet werden muss. Dies ist beispielsweise im Flugzeug beim Nichtraucher-Zeichen der Fall, das eine stilisierte Zigarettendarstellung und z.B. ein Kreuz mit roten Balken aufweist. Zur Abschattung der mit unterschiedlicher Farbe zur hinterleuchtenden Bereiche des Symbolfeldes ist es von Vorteil, wenn innerhalb des Symbolfeldes von der Rückseite der Kunststofffolie mindestens ein aus dem Kunststoff-Spritzgussmaterial bestehender Lichtabschattungssteg absteht.Depending on the information to be visually displayed, it is necessary that a Symbol field of the backlit display backlit in different colors must become. This is for example in the airplane at the non-smoking sign the case involving a stylized cigarette presentation and e.g. a cross with red bars. For shading with different color backlit areas of the symbol field, it is advantageous if within of the symbol field from the back of the plastic film at least one Light shading web consisting of the plastic injection molding material projects.

Alternativ kann zur Erzeugung von unterschiedlichen Farben innerhalb der Symbolfelder auch die Folie mit unterschiedlicher Farbe bedruckt sein und das gesamte Symbolfeld mit Hinterleuchtungslicht der gleichen Farbe, z. B. weiß, hinterleuchtet werden.Alternatively, to produce different colors within the Symbol fields also the foil be printed with different color and that entire symbol field with backlight of the same color, z. For example, knows be backlit.
