Abstract

An electron control device is known which is arranged between the two chambers of a gas discharge display device. According to the invention, the control consists of two electrode planes (lines and columns) which are formed from groups of solid conductors as straight bars arranged parallel to one another. The conductors in the line plane are arranged crossing those in the column plane and are connected with insulators at their intersections. To generate the display, the electrons are drawn in lines between two line conductors (for example Z5, Z6) from the gas discharge cavity and are split into individual electron beams by the column conductors (for example S5, S6). To suppress cross-talk, the undesired electrons are captured by individual line conductors. <IMAGE>

Description

Die Erfindung betrifft eine Elektronensteuereinrichtung (Elektrodenplatte) bestehend aus zwei parallel zum Bildschirm liegenden Elektrodenebenen (Zeilen- und Spaltenleiter), die zwischen den beiden Kammern einer Gasentladungsanzeigevorrichtung angeordnet sind, wobei in einer Kammer die Gasentladung brennt und in der anderen Kammer Hochspannung zwischen der Elektrodenplatte und dem Bildschirm angelegt ist.The invention relates to an electron control device (electrode plate) consisting of two electrode planes (row and column conductors) lying parallel to the screen, which are arranged between the two chambers of a gas discharge display device, the gas discharge burning in one chamber and high voltage between the electrode plate and in the other chamber the screen.

Ein aus zwei Kammern aufgebautes Display ist in der DE-AS 24 12 869 beschrieben und dargestellt. Bei dieser bekannten Anzeigevorrichtung brennt in der Entladungskammer die Gasentladung von einer flächenartigen Kathode zu einer zeilenförmigen Anode. Eine gelochte Steuerscheibe mit matrixförmigen Elektroden läßt die Elektronen von der Gasentladungskammer zur Beschleunigungskammer passieren, wo sie die notwendige Energie zur Leuchtstoffanregung beziehen.A display made up of two chambers is described and shown in DE-AS 24 12 869. In this known display device, the gas discharge burns in the discharge chamber from a flat cathode to a line-shaped anode. A perforated control disk with matrix-shaped electrodes allows the electrons to pass from the gas discharge chamber to the acceleration chamber, where they draw the energy required to excite the phosphor.

Die dabei verwendete Steuerscheibe besteht aus einer Isolatorplatte mit sich kreuzenden Steuerleitungen, wobei die Steuerleitungen und die Isolatorplatte an den Kreuzungspunkten Löcher haben (DE-PS 26 15 569).The control disk used here consists of an insulator plate with intersecting control lines, the control lines and the insulator plate having holes at the intersection points (DE-PS 26 15 569).

In einer anderen Ausführungsform der Steuerplatte haben die Steuerleitungen an den Kreuzungspunkten ebenfalls Löcher und sind durch verschieden geformte Isolatoren auf Distanz zueinander gehalten (DE-PS 26 15 681).In another embodiment of the control plate, the control lines also have holes at the crossing points and are kept at a distance from one another by differently shaped insulators (DE-PS 26 15 681).

Beim Plasmadisplay (DE-AS 24 12 869) ist Helium als Betriebsgas erforderlich, da andere Gase außer H2 zu stark sputtern. Wasserstoff ist jedoch mit dem Leuchtstoff bei einem farbigen Display nicht verträglich.The plasma display (DE-AS 24 12 869) requires helium as the operating gas, since gases other than H 2 sputter too strongly. However, hydrogen is not compatible with the phosphor in a colored display.

Eine Steuerscheibe bestehend aus zwei Elektrodenebenen mit gelochten Zeilen und Spalten ist für einen nebensprechen-freien Betrieb nicht ausreichend. Außerdem gelangen angeregte Elektronen durch die Steueröffnungen in den Beschleunigungsraum und führen zu einer Aufhellung des Bildschirmes.A control disc consisting of two electrode levels with perforated rows and columns is not sufficient for operation without crosstalk. In addition, excited electrons enter the acceleration space through the control openings and brighten the screen.

Zur Unterdrückung dieser Erscheinungen werden zusätzliche Elektronenebenen eingeführt (DE-OS 32 28 183).Additional electron planes are introduced to suppress these phenomena (DE-OS 32 28 183).

Neben der Einführung zusätzlicher Elektrodenebenen bereitet die gegenwärtige Steuerscheibentechnologie sowie der Einbau der Scheiben in die Zelle Schwierigkeiten. Die Steuerscheiben sind empfindlich gegen mechanische Belastungen. Außerdem ist es schwierig, sie vakuumdicht in das Display einzubauen.In addition to the introduction of additional electrode levels, the current control disk technology and the installation of the disks in the cell cause difficulties. The control discs are sensitive to mechanical loads. It is also difficult to install them vacuum-tight in the display.

Der Erfindung liegt die Aufgabe zugrunde, eine eingangs definierte Elektronensteuereinrichtung zu konzipieren. Diese Einrichtung soll den Elektrcnenfluß zwischen den beiden Kammern mit zwei Elektrodenebenen steuern und die Steuerscheibentechnologie betreffend Aufbau, mechanischer Beanspruchbarkeit und vakuumdichten Einbau vereinfachen.The invention has for its object to design an electron control device defined at the outset. This device is intended to control the flow of electrons between the two chambers with two electrode levels and to simplify the control disk technology in terms of structure, mechanical strength and vacuum-tight installation.

Diese Aufgabe wird dadurch gelöst, daß die Elektrodenebenen aus Scharen gerader, parallel angeordneter, massiver Leiter bestehen, wobei die Leiter einer Ebene zu denen der anderen Ebene kreuzweise angeordnet und an ihren Kreuzungspunkten mit Isolatoren verbunden sind. Der Vorteil der Erfindung besteht darin, daß man ein nebensprechen-freies Bild mit zwei Elektrodenebenen erzeugen kann, was bisher nicht möglich war. Außerdem wird mit der Anordnung nach der Erfindung ein einfacher und kostengünstiger Aufbau erzielt.This object is achieved in that the electrode levels consist of sheets of straight, parallel, solid conductors, the conductors of one level being arranged crosswise to those of the other level and being connected to insulators at their crossing points. The advantage of the invention is that it is possible to generate a crosstalk-free image with two electrode planes, which was not possible until now. In addition, with the Arrangement according to the invention achieved a simple and inexpensive structure.

Weitere Einzelheiten der Erfindung ergeben sich aus den Unteransprüchen.Further details of the invention emerge from the subclaims.

Die Erfindung wird an einer schematischen Darstellung eines Teils einer Elektrodenplatte erläutert. In der Figur sind mit Z die Zeilenleiter und mit S die Spaltenleiter bezeichnet. Die Isolatoren an den Kreuzungspunkten tragen das Bezugszeichen I.The invention is explained in a schematic representation of part of an electrode plate. In the figure, Z denotes the row conductors and S the column conductors. The isolators at the crossing points have the reference symbol I.

Die der Plassakammer zugewendeten Leiter (Z1 - Z10) haben konstante Teilung entsprechend dem geforderten Raster. Sie sind zueinander parallel, liegen in einer parallelen Ebene zum Bildschirm und werden als Zeilenleiter bezeichnet. Die kreuzweise mittels Isolatoren I mit den Zeilenleitern verbundenen Leiter S1 - S10 konstanter Teilung werden Spaltenleiter genannt.The conductors facing the plasma chamber (Z1 - Z10) have constant pitches according to the required grid. They are parallel to each other, lie in a plane parallel to the screen and are called row conductors. The conductors S1-S10 of constant pitch connected crosswise by means of insulators I to the row conductors are called column conductors.

Eine Zeile am Bildschirm wird dadurch angesteuert, daß zwei Zeilenleiter, zum Beispiel Z5, Z6, auf positives Potential gegenüber den benachbarten Zeilenleitern (zum Beispiel Z4, Z7) gelegt werden. Das Plasma brennt dann von der Kathode zu den angesteuerten Leitern und die Elektronen kennen den Zwischenraum der Leiter (Z5, Z6) passieren.A line on the screen is controlled by placing two line conductors, for example Z5, Z6, at a positive potential with respect to the adjacent line conductors (for example Z4, Z7). The plasma then burns from the cathode to the activated conductors and the electrons know the gap between the conductors (Z5, Z6).

Zur Unterdrückung des Nebensprechens werden die Zeilenleiter außer den für die Bilderzeugung angesteuerten Leitern (Z5, Z6) so geschaltet, daß zum Beispiel jeder zweite Leiter eine Potentialsenke für Elektronen darstellt. Bildet der Leiter Z3 eine der Potentialsenken, so herrscht zwischen den Leitern Z3, Z4 bzw. Z2, Z3 ein elektrisches Feld, das die Elektronen zum Leiter Z3 ablenkt, wo sie eingefangen werden. Außerdem können jeder zweite, dritte oder n-te Zeilenleiter, cder Kombinationen von diesen jeweils Potentialsenken für Elektronen bilden, wobei die unerwünschten Elektronen wieder in den Potentialsenken eingefangen werden.In order to suppress the crosstalk, the row conductors are switched in addition to the conductors (Z5, Z6) controlled for image generation in such a way that, for example, every second conductor represents a potential sink for electrons. If the conductor Z3 forms one of the potential sinks, an electrical field prevails between the conductors Z3, Z4 or Z2, Z3, which deflects the electrons to the conductor Z3, where they are captured. In addition, every second, third or nth row conductor, or combinations each of these form potential sinks for electrons, the undesired electrons being trapped again in the potential sinks.

Zur Beseitigung störender Elektronen, die die Zwischenräume der zur Bilderzeugung nicht angesteuerten Zeilenleiter passieren, wenn diese auf gleichem Potential liegen, werden die Potentiale benachbarter Leiter wie oben beschrieben variiert, daß in den Zwischenräumen der Leiter elektrische Felder entstehen. Sind die Zwischenräume zwischen den Zeilenleitern hoch im Verhältnis zur Breite, so genügen entsprechend schwache elektrische Felder zur Unterdrückung des Spaltennebensprechens sowie der angeregten Elektronen aus dem Gasentladungsraum.To remove interfering electrons that pass through the interstices of the row conductors that are not driven for image formation, if these are at the same potential, the potentials of adjacent conductors are varied as described above, so that electrical fields are generated in the interstices of the conductors. If the gaps between the row conductors are high in relation to the width, then correspondingly weak electric fields are sufficient to suppress the column crosstalk and the excited electrons from the gas discharge space.

Die Steuerung der Bildpunkte erfolgt zeilenweise, wobei die Elektronen jeweils zwischen zwei angesteuerten Zeilenleitern abgesaugt und von den Spaltenleitern in einzelne Elektronenstrahlen derart unterteilt werden, daß je zwei benachbarte Spaltenleiter (zum Beispiel S5, S6) auf positives Potential gegenüber den danebenliegenden Spaltenleitern (zum Beispiel S4, S7) gelegt werden. Dabei treten die Elektronen (Figur) durch die aus den Leitern Z5, Z6 und S5, S6 gebildete Öffnung und werden anschließend in der Beschleunigungskammer zur Leuchtstoffanregung beschleunigt. Das bedeutet, daß gleichzeitig nur jede dritte Steueröffnung der Elektrcdenplatte unabhängig geschaltet werden kann. Will man mit jeder Steueröffnung einen Leuchtstoffpunkt ansteuern, muß die Spaltentaktzeit auf etwa ein Drittel der Zeilentaktzeit herabgesetzt werden, um die drei Bildpunkte nacheinander anzusteuern. Diese Art der Ansteuerung wird für Vakuumdisplays im einzelnen in der DE-OS 32 47 132.7 beschrieben.The pixels are controlled line by line, with the electrons being sucked off between two driven row conductors and divided into individual electron beams by the column conductors such that two adjacent column conductors (for example S5, S6) each have a positive potential with respect to the adjacent column conductors (for example S4 , S7). The electrons (figure) pass through the opening formed by the conductors Z5, Z6 and S5, S6 and are then accelerated in the acceleration chamber to stimulate the phosphor. This means that only every third control opening of the electrode plate can be switched independently at the same time. If you want to control a fluorescent dot with each control opening, the column cycle time must be reduced to about a third of the line cycle time in order to control the three pixels one after the other. This type of control is described in detail for vacuum displays in DE-OS 32 47 132.7.

Die Grausteuerung der Bildpunkte erfolgt durch Pulsdauermodulation benachbarter Spaltenleiter, wie sie bereits in der DE-OS 29 38 759 dargestellt ist.The gray control of the pixels is carried out by pulse duration modulation of adjacent column conductors, as is already shown in DE-OS 29 38 759.

Bei einer anderen Art der Spaltenansteuerung wird jeder dritte Spaltenleiter (zum Beispiel S4, S7) dauernd auf negatives Potential gegenüber den anderen Leitern der Elektrodenplatte gelegt, um die danebenliegenden Öffnungen dauernd zu sperren.In another type of column control, every third column conductor (for example S4, S7) is continuously placed at a negative potential with respect to the other conductors of the electrode plate in order to permanently block the openings lying next to it.

Mit den dazwischenliegenden Spaltenleiterpaaren (zum Beispiel S5, S6) kann der Weg für Elektronen geöffnet oder geschlossen werden.The path for electrons can be opened or closed with the intermediate pairs of column conductors (e.g. S5, S6).

Bei dieser Spaltenansteuerung ist das Bildpunktraster dreimal so groß wie das Spaltenraster der Elektrodenplatte.With this column control, the pixel grid is three times as large as the column grid of the electrode plate.

Zur Erzeugung farbiger Bilder muß das Display zum hochauflösendent Bildschirm eine entsprechende Elektronensteuereinrichtung enthalten.To generate colored images, the display for the high-resolution screen must contain an appropriate electron control device.

Eine entsprechende Elektronensteuereinrichtung stellt die Elektrodenplatte dar,'die Gegenstand der Erfindung ist, wobei die drei Grundfarben des Farbdisplays in periodischer Reihenfolge streifenförmig gegenüber den Zwischenräumen der Spaltenleiter am Bildschirm angeordnet sind.A corresponding electron control device is represented by the electrode plate, which is the subject of the invention, the three primary colors of the color display being arranged in a strip-like manner in periodic order in relation to the spaces between the column conductors on the screen.

Der Bildschirm wird derart angesteuert, daß während eines Zeilentaktes drei benachbarte Spaltenöffnungen nacheinander angesteuert werden, wobei die Elektronenstrahlen mit der entsprechenden Information moduliert werden (DE-OS 32 47 132.7).The screen is driven in such a way that three adjacent column openings are driven in succession during a line cycle, the electron beams being modulated with the corresponding information (DE-OS 32 47 132.7).

Im Gegensatz zu dieser bekannten Methode (DE-OS 32 47 132.7) wird eine andere Methode zur Erzeugung farbiger Bilder durch Nacrablenkung von Elektronenstrahlen in der DE-OS 27 42 555 beschrieben. Danach wird ein Elektronenstrahl pro Weißpunkt erzeugt, der die drei Grundfarben abtastet, die streifenförmig gegenüber den Ablenkelektroden am Bildschirm angeordnet sind. Jeder Spalte der Elektrodenmatrix sind jeweils zwei Ablenkelektroden nachgeordnet, wobei durch Anlegen von entsprechenden Potentialen auf die Elektroden alle Elektronenstrahlen zuerst nach einer Seite abgelenkt, dann gerade durchgelassen und anschließend nach der anderen Seite abgelenkt werden. Die Elektronenstrahlen erhalten beim Abtasten der einzelnen Grundfarben über die Spalten die entsprechende Farbinformation.In contrast to this known method (DE-OS 32 47 132.7), another method for producing colored images by means of Nacrablen deflection of electron beams is described in DE-OS 27 42 555. Then an electron beam is generated for each white point, which scans the three primary colors, which are stripe-shaped compared to the Deflection electrodes are arranged on the screen. Each column of the electrode matrix is followed by two deflecting electrodes, whereby by applying corresponding potentials to the electrodes, all the electron beams are first deflected to one side, then passed straight through and then deflected to the other side. When scanning the individual primary colors, the electron beams receive the corresponding color information via the columns.

Wird bei der Elektrcdenplatte jeder dritte Spaltenleiter, zum Beispiel S4, S7, auf konstantes Sperrpotential gelegt um die neben den Drähten liegenden Öffnungen dauernd zu sperren, so stehen je zwei Leiter zur Steuerung der Elektronen zwischen diesen beiden Leitern, zum Beispiel S5, S6, zur Verfugung. Mit diesen Leiterpaaren können die Elektronenstrahlen gesperrt oder durchgelassen, aber auch zusätzlich noch abgelenkt werden, wenn die Ablenkspannung zwischen den Leiterpaaren kleiner ist als der Spannungshub zum Öffnen oder Sperren der Elektronenstrahlen. Sind die drei Grundfarben in periodischer Reihenfolge streifenförmig gegenüber den Zwischenräumen der Spaltenleiter der Elektrodenplatte am Bildschirm angeordnet, so können unter den angegebenen Bedingungen die Elektrcnenstrahlen durch die Leiterpaare mit der Farbinformation moduliert und zu den entsprechenden Farbstreifen gelenkt werden.If in the electrode plate every third column conductor, for example S4, S7, is set to a constant blocking potential in order to permanently block the openings next to the wires, two conductors are available for controlling the electrons between these two conductors, for example S5, S6 Grouting. With these pairs of conductors, the electron beams can be blocked or passed, but can also be deflected if the deflection voltage between the pairs of conductors is smaller than the voltage swing for opening or blocking the electron beams. If the three primary colors are arranged on the screen in strips in a periodic sequence in relation to the spaces between the column conductors of the electrode plate, the electron beams can be modulated with the color information by the conductor pairs under the specified conditions and directed to the corresponding color strips.

Die Elektrodenplatte kann auf verschiedene Weise aufgebaut werden:

  • 1. Die Leiter der Elektrodenebenen (Zeilen und Spalten) werden separat ätztechnisch oder mittels Drahtebenen hergestellt und beim Einbau in die Zelle an den Kreuzungspunkten mit Glaslot miteinander verbunden, sowie an den Durchführungen vakuumdicht eingeschmolzen (DE-OS 32 47 132.7).
  • 2. Gesonderter Aufbau der Elektrodenplatte.
The electrode plate can be constructed in different ways:
  • 1. The conductors of the electrode levels (rows and columns) are manufactured separately using etching technology or by means of wire levels and are connected to one another at the crossing points with glass solder when they are installed in the cell, and are melted down in a vacuum-tight manner at the bushings (DE-OS 32 47 132.7).
  • 2. Separate construction of the electrode plate.

Bei der ätztechnischen Herstellung der Elektrodenebenen wird der Ätzprozeß unterbrochen, eine die Ebenen in einzelne Leiter zerfallen. Dann werden die Leiter mit Glaslot kreuzweise verbunden und anschließend wird das Gebilde fertiggeätzt. Daraufhin kann die Elektrodenplatte nach dem üblichen Verfahren (zum Beispiel DE-AS 24 12 869) in die Zelle eingebaut werden.The etching process is interrupted during the etching production of the electrode planes, and the planes disintegrate into individual conductors. Then the conductors are cross-connected with glass solder and then the structure is etched. The electrode plate can then be installed in the cell using the usual method (for example DE-AS 24 12 869).
