Abstract

The fixation has an artwork (1) connected to a high pressure generator (6) by electrical contacts (5), where the artwork includes an electrically conductive coating on its backside. The electrical contacts are designed as press buttons. The artwork is isolated and movably suspended from stepping motors (7). A side of a lens plate (2) is provided with an electrically conductive coating. An independent claim is also included for a method of controlling lenticular displays.

Description

Die Erfindung betrifft eine Lenticular- Display- Fixierung für Werbedisplays mit animierten Bildern, die eine künstliche Hinterleuchtung besitzen können, aber auch von Tageslicht beleuchtet sein können,
wobei ein Lenticularbild oder eine in Richtung des Betrachters davor angeordnete Linsenscheibe bewegt wird.The invention relates to a lenticular display fixation for advertising displays with animated images, which may have an artificial backlight, but may also be illuminated by daylight,
wherein a lenticular image or a lens disc arranged in front of the observer is moved.

Bisherige Lenticular- Displays mit integriertem Bewegungsablauf verwenden zum Andrücken des Artworks an die Linsenscheibe entweder eine extrem präzise Führung oder Watte.Previous Use lenticular displays with integrated motion sequence for pressing the Artworks to the lens disk either an extremely precise guide or Cotton wool.

Die Präzisionsführung ist teuer in der Fertigung, Watte erbringt einen gleichmäßig hohen Andruck und damit Reibung, die Motorkraft kostet, auch wenn er nicht benötigt wird.The Precision guidance is expensive in manufacturing, cotton wool provides a consistently high Pressure and thus friction, which costs engine power, even if he does not needed becomes.

Es ist deshalb Aufgabe der Erfindung, eine solche Lenticular- Display-Fixierung zu schaffen, wodurch Artwork und Linsenscheibe perfekt und energiesparend aneinandergedrückt werden.It It is therefore an object of the invention to provide such a lenticular display fixation, which artwork and lens disk are pressed together perfectly and energy-saving.

Zur Definition soll noch gesagt werden, dass unter dem Lenticularbild oder auch Artwork ineinander verschachtelte, linienförmige Bilder zu verstehen sind. Sie sind durch Computerberechnung aus mehreren Einzelbildern zusammengesetzt. Der Aufdruck der Lenticularbilder erfolgt entweder auf Papier oder – bei Betrieb mit Hinterleuchtung – auf Folie. Unter der Linsenscheibe versteht man eine dünne durchsichtige Kunststoffscheibe – in der Regel zwischen 0,1 Millimeter und mehreren Millimetern dick -, die auf der dem Artwork zugewandten Seite glatt ist und auf der anderen Seite zylindrische Linsen aufweist. Die Feinheit des Linienrasters von Artwork und Linsenscheibe müssen dabei übereinstimmen. Durch die Gegeneinander-Verschiebung von Artwork und Linsenscheibe senkrecht zum Linienraster entstehen wechselnde Bilder bzw. je nach Berechnung Morphing-, Zoom und 3D-Effekte.to Definition should be said that under the lenticular image or even artwork nested, line-shaped images to be understood. They are made by computer calculation of several Composed of individual images. The imprint of the lenticular images takes place either on paper or - when operated with backlight - on foil. The lens disc is a thin transparent plastic disc - in the Usually between 0.1 millimeters and several millimeters thick - the on the side facing the artwork is smooth and on the other Side cylindrical lenses. The fineness of the line grid of artwork and lens disk need agree. By the opposition of artwork and lens slice perpendicular to the line grid arise changing Pictures or, depending on the calculation, morphing, zoom and 3D effects.

Die gestellte Aufgabe wird entsprechend des ersten Anspruches und der folgenden Unteransprüche gelöst.The Asked object is according to the first claim and the the following subclaims solved.

Entscheidend ist, dass die Rückseite des Artworks mit einer wenigstens teilweise elektrisch leitfähigen Beschichtung versehen ist, die über elektrische Kontakte oder Druckknöpfe mit einem Hochspannungsgenerator verbunden ist.critical is that the back the artwork with an at least partially electrically conductive coating that is over electrical contacts or pushbuttons with a high voltage generator connected is.

Dessen Spannungsmaximum liegt in der Ruhephase des Artwork dort an und dessen Spannungsminimum in der Bewegung des Artwork.Whose Maximum tension is in the resting phase of the artwork there and its tension minimum in the movement of the artwork.

Praktisch liegt eine statische Aufladung der Folien und des Artwork mit entgegengesetzter Polarität in der Ruhephase vor. In der Folge ziehen sich Artwork und Lenticularfolie an.Practically is a static charge of the slides and the artwork with opposite polarity in the resting phase. As a result, artwork and lenticular film are drawn at.

In der Bewegung ist die elektrische Feldstärke Null bis entgegengesetzt. Dadurch kommt es zum Lösen oder Abstoßen der Folien.In In motion, the electric field strength is zero to opposite. This leads to the release or repelling the slides.

Auch an einen kurzen, entgegengesetzten Spannungsimpuls kurz vor oder während der Bewegung zum Lösen der Folien ist gedacht.Also to a short, opposite voltage pulse just before or while the movement to release the slides is meant.

Man hat so eine elegante Möglichkeit geschaffen, ohne mechanische Hilfsmittel, wie Watte oder extrem präzise Führungen den optisch notwendigen Andruck zwischen Artwork und Linsenscheibe zu sichern.you has such an elegant possibility created without mechanical aids, such as cotton or extreme precise guides the optically necessary pressure between the artwork and lens disk to back up.
