Description
Die Erfindung betrifft eine Anzeigeneinheit, insbesondere für Kraftfahrzeuge, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a display unit, in particular for motor vehicles, according to the generic term of claim 1.
Der Einsatz von Anzeigeneinheiten in Kraftfahrzeugen ist vielfältig, z.B. als Kontrollvorrichtungen oder Tasten. Eine übliche Anzeigeneinheit kann ein Anzeigenelement mit einer lichtundurchlässigen Deckschicht mit Symbolöffnungen und eine lichtdurchlässige d.h. transparente Schicht und eine Lichtquelle aufweisen, wobei die Lichtquelle durch die Symbolöffnungen gebildete Symbole beleuchtet. Wichtig ist, dass die Symbole sowohl tagsüber als auch nachts einen guten Kontrast zu der Deckschicht bilden und somit gut erkennbar sind.The use of ad units in motor vehicles is varied e.g. as control devices or buttons. A common ad unit can be a display element with an opaque top layer with symbol openings and a translucent i.e. Have transparent layer and a light source, wherein the light source through the symbol openings formed symbols illuminated. It is important that the symbols are both during the day also form a good contrast to the top layer at night and are clearly recognizable.
Aus der
Eine solche Anordnung mit einem transparenten Träger und einer Abdeckung, d.h. mit einer transparenten Schicht und einer Deckschicht, führt zu einer guten Erkennbarkeit der Symbole wenn die Deckschicht dunkel und die transparente Schicht hell und damit auch diffus ist. Ist jedoch die Darstellung eines dunklen Symbols mit einem hellen Hintergrund erwünscht, so muss als transparente Schicht eine Rauchglasschicht, d.h. eine dunkel eingefärbte, transparente Schicht verwendet werden. Dabei kommt es aber zu einer bezüglich Homogenität und Blickwinkel nicht zufriedenstellenden Ausleuchtung des Symbols. Ursache dafür ist die geringe Streuwirkung des Rauchglases, was dazu führt, dass die vom Betrachter wahrgenommene Helligkeit stark mit größer werdendem Blickwinkel zur Senkrechten auf die Rauchglasschicht abnimmt.Such an arrangement with a transparent carrier and a cover, i.e. with a transparent layer and one Top layer, leads to good recognition of the symbols when the top layer is dark and the transparent layer is light and therefore also diffuse. is however, the display of a dark symbol with a light background is desired, so As a transparent layer, a smoked glass layer, i.e. one dark colored, transparent Layer can be used. However, this leads to a homogeneity and perspective unsatisfactory illumination of the symbol. The reason for this is the low scattering effect of the smoked glass, which leads to that of the viewer perceived brightness strongly with increasing perspective Vertical on the smoked glass layer decreases.

und mit einer Beleuchtung ist aus der
Aufgabe der Erfindung ist es, eine Anzeigeneinheit gemäß dem Oberbegriff des Anspruchs 1 zu entwickeln, die sowohl tagsüber als auch nachts eine gute Erkennbarkeit der Symbole ermöglicht, die flexibel verwendbar ist und die einen geringen Herstellungs- und Montageaufwand erfordert.The object of the invention is a Ad unit according to the generic term of claim 1 to develop a good both during the day and at night Recognizability of the symbols enables which can be used flexibly and which has a low manufacturing and assembly effort required.
Die Aufgabe ist durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The task is due to the characteristic features of claim 1 solved.
Erfindungsgemäß weist das Ausleuchtelement eine Streuschicht, d.h. eine lichtstreuende transparente Schicht auf, die flächig mit der Rauchglasschicht des Anzeigenelementes verbunden ist. Als Streuschicht kann eine an sich bekannte weiße Kunststoffschicht z.B. aus glasklarem PC (Polycarbonat) mit weißen Partikeln, als Rauchglasschicht eine dunkle Kunststoffschicht aus glasklarem PC mit dunklen z.B. schwarzen Partikeln und als Deckschicht z.B. eine helle Farbschicht eingesetzt werden. Die helle Farbschicht kann z.B. weiß, beige oder silbern sein und durch Lackieren oder durch Bedrucken hergestellt sein. Die Streuwirkung der Streuschicht ermöglicht mit einfachen Mitteln eine Vergleichmäßigung der Ausleuchtung der Symbole durch eine homogene Aufweitung der Lichtstrahlen von der Lichtquelle und damit neben einer guten Erkennbarkeit tagsüber auch nachts bei eingeschalteter Beleuchtung eine gute Erkennbarkeit der Symbole. Die Streuschicht liegt zumindest im Bereich der Symbole, d.h. unter den Symbolöffnungen und an den Rändern der Symbolöffnungen, flächig an der Rauchglasschicht an. Neben der Streuschicht kann das Ausleuchtelement Halterungen aufweisen, mit denen die Streuschicht flächig mit der Rauchglasschicht verbunden werden kann. Ein Ausleuchtungselement mit einer Streu schicht ist einfach und in beliebigen Größen herstellbar, so dass eine erfindungsgemäße Anzeigeneinheit flexibel für Symbole verschiedener Form und Größe einsetzbar ist.According to the illumination element a scattering layer, i.e. a light-scattering transparent layer on that flat is connected to the smoked glass layer of the display element. As Scatter layer can be a white plastic layer known per se e.g. out crystal-clear PC (polycarbonate) with white particles, as a smoked glass layer a dark plastic layer made of crystal-clear PC with dark e.g. black particles and as a top layer e.g. a light layer of paint be used. The light color layer can e.g. white, beige or be silver and produced by painting or by printing his. The scattering effect of the scattering layer enables simple means an equalization of the Illumination of the symbols through a homogeneous expansion of the light rays from the light source and thus in addition to good visibility during the day good visibility at night with the lighting switched on Symbols. The scattering layer is at least in the area of the symbols, i.e. under the symbol openings and on the edges the symbol openings, flat on the smoked glass layer. In addition to the diffusion layer, the illuminating element Have brackets with which the scattering layer along with the smoked glass layer can be connected. A lighting element with a spreading layer is easy and can be made in any size, so that a display unit according to the invention flexible for Symbols of various shapes and sizes can be used.
Gemäß Anspruch 2 kann die Streuschicht mit der Rauchglasschicht einteilig verbunden sein. Das hat den Vorteil, dass die Anzeigeneinheit aus nur zwei Teilen, nämlich dem Anzeigenelement mit integriertem Ausleuchtelement und der Lichtquelle besteht.According to claim 2, the scattering layer with the smoked glass layer be connected in one piece. That has the advantage, that the display unit consists of only two parts, namely the display element integrated lighting element and the light source.
Die Streuschicht des Ausleuchtelementes und die Rauchglasschicht des Anzeigenelementes gemäß Anspruch 3 als zwei mit einem 2-Komponentenspritzverfahren erzeugte Schichten auszubilden, ermöglicht eine einfach herzustellende Anzeigeneinheit hoher Qualität. Dabei wird z.B. zunächst die Rauchglasschicht aus dunklem Kunststoff gespritzt und direkt an die Rauchglasschicht anschließend die Streuschicht aus weißem Kunststoff angespritzt.Forming the diffusion layer of the illuminating element and the smoked glass layer of the display element according to claim 3 as two layers produced with a 2-component injection molding process enables a display unit of high quality that is easy to manufacture. For example, the smoked glass layer made of dark plastic is first injected and then the smoked glass layer is applied directly to it Sprayed layer of white plastic.
Als Lichtquelle kann gemäß Anspruch 4 eine Leuchtdiode eingesetzt werden. Die Leuchtdiode sollte mit einem Abstand zur Streuschicht angewendet werden, der ein Beleuchten der Streuschicht im Bereich der Symbole ermöglicht.As a light source can according to claim 4 a light emitting diode can be used. The LED should go with a distance from the scattering layer can be used, which is an illumination the scattering layer in the area of the symbols enables.
Als Lichtquelle kann gemäß Anspruch 5 auch ein Lichtleiter und eine Leuchtdiode eingesetzt werden. Bevorzugt erstreckt sich ein der Streuschicht zugewandtes Ende des Lichtleiters über den Bereich der Symbole, zumindest über die Symbolöffnungen, und befindet sich am anderen Ende des Lichtleiters die Leuchtdiode.As a light source can according to claim 5 an optical fiber and a light emitting diode can also be used. Prefers an end of the light guide facing the scattering layer extends over the Area of symbols, at least about the symbol openings, and the LED is at the other end of the light guide.
Gemäß Anspruch 6 als Deckschicht eine Lackschicht einzusetzen und die Symbolöffnungen durch Laseranwendungen zu erzeugen, führt zu Symbolöffnungen mit glatten Rändern. Das verbessert die Erkennbarkeit der Symbole.According to claim 6 as a top layer to apply a layer of lacquer and the symbol openings through laser applications to generate leads to symbol openings with smooth edges. This improves the recognizability of the symbols.
