Abstract
Die Erfindung betrifft eine elektrophoretische Displayfolie, die jeweils eine in Mikrokammern gefasste Lösung mit geladenen Partikeln aufweist, die über ein anliegendes elektrisches Feld positionierbar sind. Erfindungsgemäß weisen die Lösungen in den Kammern (EFR, EFB) unterschiedliche Farben auf.The The invention relates to an electrophoretic display film, each a solution in microcompartments with charged particles having an applied electrical Field are positionable. According to the invention, the solutions in the chambers (EFR, EFB) different colors.
Description
Die Erfindung betrifft eine elektrophoretische Displayfolie gemäß dem Oberbegriff des Patentanspruchs 1 beziehungsweise 2.The The invention relates to an electrophoretic display film according to the preamble of claim 1 or 2.
In vielen Bereichen des Alltags werden von Hand gefertigte Zeichnungen oder Notizen zur Informations-Übertragung oder -speicherung benutzt. Dieses Vorgehen ist mit einigen Nachteilen behaftet, so beispielsweise der hohe Aufwand zum Kopieren und Verteilen der Notizen, die Notwendigkeit, ständig für Ersatzpapier sorgen zu müssen, und die fehlende Möglichkeit, Geschriebenes zu löschen.In In many areas of everyday life are hand-made drawings or notes for information transmission or storage used. This procedure has some disadvantages Afflicted, for example, the high cost of copying and distribution the notes, the need to constantly provide replacement paper, and the missing possibility To delete written.
Derzeit
entwickeln weltweit einige Firmen elektronische Displays, die sich
der Elektrophorese zur Darstellung von Bildinhalten bedienen. Diese
Folien werden auch als elektronische Tinte bezeichnet. Das Funktionsprinzip
einer elektrophoretischen Displayfolie EF ist in
Die
elektrophoretischen Displayfolie EF weist mit einer Lösung gefüllte Mikrokammern

beispielsweise negativ geladene Partikel (
Das elektrische Feld wird beispielsweise zwischen einer flächigen Gegenelektrode und einer metallischen Stiftspitze erzeugt. Weiter kann die Displayfolie über eine Elektroden struktur bewegt werden und dabei der Bildinhalt auf der Folie generiert werfen.The electric field, for example, between a planar counter electrode and a metallic pen nib. Next, the display film over a Electrode structure to be moved while keeping the image content on the Throw slide generated.
Der Erfindung liegt die Aufgabe zugrunde, eine Displayfolie anzugeben, die eine mehrfarbige Darstellung von Inhalten ermöglicht.Of the Invention is based on the object of specifying a display film which allows a multicolored presentation of content.
Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch 1 angegebenem Merkmale gelöst.These The object is achieved by the solved in claim 1 given features.
Die erfindungsgemäße Displayfolie ermöglicht durch die Mehrfarbigkeit die Darstellung von komplexen oder optisch ansprechenden Zeichnungen und Notizen.The inventive display film allows through the multicolor the representation of complex or optical attractive drawings and notes.
Im Folgenden wird die Erfindung an Hand eines in der Zeichnung dargestellten Ausführungsbeispiele beschrieben. Dabei zeigen:in the The invention will be described below with reference to a drawing embodiments described. Showing:
Die erfindungsgemäß ausgebildete elektrophoretische Displayfolie ermöglicht ein mehrfarbiges Schreiben und Zeichnen. Dies wird erreicht durch Kammern (EFR, EFB), die mit Flüssigkeiten unterschiedlicher Farben gefüllt sind. Bei einer alternativen Ausführungsform sind die in den Kammern (EFR, EFB) enthaltenen Partikel unterschiedlich gefärbt.The formed according to the invention Electrophoretic display film allows multi-color writing and drawing. This is achieved by means of chambers (EFR, EFB) with liquids filled different colors are. In an alternative embodiment, the in the Chambers (EFR, EFB) contained differently colored particles.
Die
Für ein „farbiges Schreiben" sind dann beispielsweise durch eine entsprechende Anordnung der Gegenelektroden die gewünschten Farbkammern anzusteuern.For a "colored Writing "are then, for example, by a corresponding arrangement of the counter electrodes the desired To control color chambers.
Die erfindungsgemäße Displayfolie lässt auch Mischfarben zu. Würde man in obigem Beispiel die beiden Farbkammern für rot und blaue Farbe gemeinsam ansteuert, so wäre die „Schriftfarbe" ein Violett-Ton als Kombination aus blau und rot. Ein lineares Verhältnis zwischen elektrischem Feld und Farbumschlag vorausgesetzt, können durch Kombination von roten, grünen und blauen Kammern sowie der Erzeugung eines entsprechenden elektrischen Feldes für jede Grundfarbe annähernd beliebige Mischfarben erzeugt werden.The inventive display film leaves too Mixed colors too. Would in the example above, the two color chambers for red and blue color are common controls, so would be the "font color" is a violet tone as a combination of blue and red. A linear relationship between electric field and color change provided by Combination of red, green and blue chambers as well as the generation of a corresponding electrical Field for approximate each base color Any mixed colors are generated.
Insbesondere für die Darstellung von Mischfarben sollten die Mikrokammern ausreichend klein ausgebildet sein, so dass der Betrachter diese nicht mehr optisch auflösen kann.Especially for the Representation of mixed colors, the microcompartments should be sufficient be small, so that the viewer no longer optically dissolve can.
