Abstract

The screen includes image points, e.g. from liquid crystal or other optically reacting medium, located at interfaces of electric conductors, which are activated when an AC voltage is applied on the conductors. The voltage produces a field sufficient for the activation of an image point, only if both conductors are supplied with equal current frequencies. A color screen may be provided by stacking several individually colored screens, e.g. in the colors red, green, and blue.

Description

Die Erfindung betrifft eine Vorrichtung entsprechend dem Oberbe­ griff des Anspruchs 1.The invention relates to a device according to the Oberbe handle of claim 1.

Flachbildschirme, vor allem auf LCD-Basis, besitzen den großen Vor­ teil einer, z. B. gegenüber der Braunschen Röhre, sehr flachen Bau­ weise. Ihr Einbau, in Farbausführung, in Geräte wie Notebooks, Kameras bis hin zu Fernsehgeräten nimmt in der Gegenwart explo­ sionsartig zu.Flat screens, especially those based on LCD, have the big advantage part one, e.g. B. compared to the Braun tube, very flat construction wise. Your installation, in color, in devices such as notebooks, Cameras to televisions are exploited in the present sions like.

Der komplizierte Aufbau beschränkt jedoch ihre Einsatzmöglich­ keiten auf den Einbau in Geräte jeglicher Art. Auch dürften rela­ tiv hohe Herstellungskosten einer Verwendung als "billiges Bild­ schirmmaterial" entgegenstehen.However, the complicated structure limits their possible use on installation in devices of any kind. Rela tiv high manufacturing costs of use as a "cheap picture shield material ".

Dies soll mit dem (LCD)-Ultraflachbildschirm vorliegen, der keine Steuerungen und dergleichen am Bildschirm selbst besitzt. Bei einer Dicke bis hinunter zur derberen Folie, auch wenn erfor­ derlich ihrer Flexibilität, eröffnet er ein Feld völlig neuer Bildschirmeinsatzmöglichkeiten, so z. B. als Werbeträger an beleuch­ teten Litfaßsäulen, Wänden, Aufstellern und Schildern, als Groß­ bildschirm an Kaufhäusern, in Stadien, bis, bei genügender Qualität evtl. sogar, hin als Bildschirm von Monitoren u. Fernsehgeräten, od. als ausrollbare Zeitschrift usw. This is said to be the case with the (LCD) ultra flat screen, which is none Controls and the like on the screen itself. With a thickness down to the coarser film, even if required Because of their flexibility, it opens up a completely new field Screen applications, such. B. as advertising medium to illuminate advertising columns, walls, stands and signs, as large screen at department stores, in stadiums, up to, with sufficient quality possibly even as a monitor screen u. Televisions, or as a roll-out magazine etc.  

Der (LCD)-Ultraflachbildschirm ist zunächst einmal aufgebaut wie jedes einfache Anzeigen-Display. Nur sind bei ihm keine Figuren oder Zahlensegmente vorgegeben, sondern der Flüssigkristall ist als Punktraster zwischen den meist horizontal und vertikal ver­ laufenden elektr. Leitern, jeweils ein Feld pro Schnittpunkt, eingelagert, (Abb. 1). Das Aktivieren eines Bildpunktes erfolgt mittels Wechselstroms. Dabei ist den elektr. Leitern einer Seite (in Abb. 1 den horizontal verlaufenden) jeweils eine bestimmte, feste Wechselstromfrequenz pro Leiter zugeteilt. Auf den Leitern der anderen Seite (in Abb. 1 den vertikal verlaufenden) liegen auf jedem Leiter jeweils alle Wechselstromfrequenzen an, die be­ nötigt werden, die gewünschten Bildpunkte zu aktivieren.The (LCD) ultra-flat screen is initially structured like any simple display. Only no figures or number segments are specified for him, but the liquid crystal is a grid of points between the mostly horizontal and vertical ver running electr. Ladders, one field per intersection, stored ( Fig. 1). A pixel is activated by means of alternating current. The electr. Conductors on one side (in Fig. 1 the horizontal ones) are each assigned a specific, fixed AC frequency per conductor. On the conductors on the other side (the vertical ones in Fig. 1), all AC frequencies are present on each conductor, which are required to activate the desired pixels.

Die angelegte Stromstärke und Spannung sind derart fein einge­ stellt, daß das elektr. Feld einer Schnittstelle, eines Bildpunktes nur in dem Fall ausreichend ist, den Flüssigkristall o. ä. anzure­ gen, wenn beide sich schneidenden und überlagernden Leiter die gleiche Wechselstromfrequenz führen.The applied current and voltage are so fine represents that the electr. Field of an interface, a pixel is sufficient only in the case, the liquid crystal or the like if both intersecting and overlapping conductors carry the same AC frequency.

Diese Technologie ließe auch einen Farbbildschirm zu, indem mehrere Einzelbildschirme deren Material an den Bildpunkten z. B. rot, grün u. blau eingefärbt ist, übereinander geschichtet werden.This technology also allowed for a color screen by several Single screens whose material at the pixels z. B. red, green u. is colored blue, can be layered on top of each other.

Durch gezielte Zuschaltung der einzelnen nun Farbpunkte ließen sich Farben leicht mischen, bei definierten Flimmern bestimmter sogar auf kleiner Fläche sehr scharf, (Abb. 2).By deliberately switching on the individual color dots, colors could be mixed easily, with defined flicker certain colors even very small, ( Fig. 2).

Claims (2)

1. Ultraflachbildschirm, dadurch gekennzeichnet, daß die sich an den Schnittstellen seiner elektr. Leiter befindenden Bildpunkte, z. B. aus Flüssigkristall od. jedem anderen optisch reagierenden Medium, aktiviert werden, indem auf den Leitern ein Wechselstrom anliegt, der nur in dem Fall ein zur Aktivierung eines Bildpunk­ tes genügendes Feld erzeugt, wenn beide Leiter die gleiche Stromfrequenz führen, (Abb. 1).1. Ultra flat screen, characterized in that at the interfaces of its electrical. Head pixels, z. B. from liquid crystal or any other optically reactive medium, be activated by applying an alternating current to the conductors, which only produces a field sufficient to activate a pixel if both conductors have the same current frequency ( Fig. 1 ). 2. Ultraflachbildschirm nach Anspruch 1, dadurch gekennzeichnet, daß sich durch Aufeinanderfügen mehrerer, z. B. in den Farben rot, grün und blau, teileingefärbter Einzelbildschirme ein Farbbildschirm herstellen läßt, (Abb. 2).2. Ultra flat screen according to claim 1, characterized in that by joining several, z. B. in the colors red, green and blue, partially colored single screens can produce a color screen ( Fig. 2).
