Es sind bereits Bildschirme zur Wiedergabe farbiger Bilder bekannt, die aus einer Vielzahl von dicht nebeneinanderliegenden Stirnflächen von Lichtleitfasern bestehen. Aus der deutschen Offenlegungsschrift 2*132 O67 ist bereits ein aus Lichtleitfasern bestehender Leuchtschirm bekannt, bei -welchem die einzelnen Lichtleitfasern auf der Betrachterseite in einem größeren Abstand zueinander angeordnet sind, wodurch die Bildschirmfläche gegenüber dem Querschnitt des Lichtleitfaserbündels vergrößert wird.There are already known screens for reproducing colored images, which consist of a large number of closely spaced end faces of optical fibers. From the German Offenlegungsschri ft 2 * 132 O67 a luminescent screen consisting of optical fibers is already known, in which the individual optical fibers are arranged at a greater distance from one another on the viewer side, whereby the screen area is enlarged compared to the cross-section of the optical fiber bundle.
Die Aufgabe der vorliegenden Erfindung besteht darin, einen neuartigen Bildschirm der eingangs genannten Art anzugeben, der hinsichtlich seiner Anwendung bei farbiger Wiedergabe verbessert ist.The object of the present invention is to provide a novel screen of the type mentioned above, which improves in terms of its application in color reproduction is.
Gemäß der Erfindung wird vorgeschlagen, daß jeweils eine Lichtleitfaser bzw. Lichtleitfaserbündel von jeder Grundfarbe Gruppen dicht beieinanderliegender Lichtleitfaserstirnflächen bilden, und daß die einzelnen Gruppen zumindest in einer seitlichen Richtung einen größeren Abstand voneinander besitzen als die Lichtleitfaser Stirnflächen Innerhalb einer Gruppe.According to the invention it is proposed that each one optical fiber or optical fiber bundles of each primary color form groups of closely spaced optical fiber end faces, and that the individual groups have a greater distance from one another than the optical fiber, at least in one lateral direction End faces within a group.

Anhand des in der Figur dargestellten bevorzugten Ausführungsbeispieles wird die Erfindung nachfolgend naher erklärt.The invention is explained in more detail below on the basis of the preferred exemplary embodiment shown in the figure.
Die Figur zeigt einen Ausschnitt eines erfindungsgemäßen Bildschirms 1 in Aufsicht. Bei dem dargestellten Ausführungsbeispiel sind jeweils die Stirnflächen dreier in den Grundfarben grün-, rot-, blauleuchtender Lichtleitfasern zu Dreier-Gruppen zusammengefaßt« Mit jedem Triplett lassen sich weitgehend alle darstellbaren Farben darstellen. Je nach Intensität der einzelnen Grundfarben erfolgt im menschlichen Auge eine additive Mischung der Strahlungen, so daß eine solche Dreier-Gruppe aus einiger Entfernung jeweils insgesamt in einer Farbe leuchtend gesehen wird.The figure shows a detail of a screen 1 according to the invention in a plan view. In the illustrated embodiment, the end faces are three in the basic colors Green, red, and blue-shining optical fibers combined into groups of three «With every triplet, almost all represent representable colors. Depending on the intensity of the individual basic colors, there is an additive in the human eye Mixing of the radiations so that such a group of three shines in one color from a distance is seen.
Die einzelnen Dreier-Gruppen 2 sind nun gemäß der Erfindung in einem gewissen Abstand voneinander angeordnet, wobei die Abstände der einzelnen Dreier-Gruppen voneinander großer sind als die Abstände der einzelnen Lichtleitfasern G, R, B voneinander innerhalb einer Gruppe. Der Abstand der einzelnen Gruppen voneinander wird so gewählt, daß bei üblichem gewünschten Betrachterabstand die Mosaikstruktur des Bildschirmes vom Betrachter noch nicht als störend empfunden wird. Vorzugsweise wird der Abstand der Gruppen voneinander so gewählt, daß eine Vergrößerung der BildschirmflSche um etwa den Faktor 1,5 bis 10 erzielt wird. Die Vergrößerung des Bildschirmes ist bezogen auf einen Bildschirm, bei welchem die einzelnen Gruppen dicht nebeneinander liegen wurden.The individual groups of three 2 are now arranged according to the invention at a certain distance from one another, the distances between the individual groups of three being greater than the distances between the individual optical fibers G, R, B from one another within a group. The spacing of the individual groups from one another is chosen so that the mosaic structure of the screen is not yet perceived as disturbing by the observer at the usual desired observer spacing. The distance between the groups is preferably selected such that the screen area is enlarged by a factor of about 1.5 to 10. The enlargement of the screen is based on a screen on which the individual groups are close to one another.

surfaces of the / three basic colors emitting optical fibers can also z. B. be arranged in a row next to each other. Instead of a single optical fiber, optical fiber bundles with, for example, two to five optical fibers can also be used. The end faces of the optical fibers or optical fiber bundles facing the viewer can also be designed as optically scattering or also as optically converging lenses. To hold the individual optical fiber groups, a plastic or a potting compound can be used, in which these ends of the optical fibers are embedded at the desired distance from one another. In this way, a flat or curved screen surface can be achieved.
