- the control lines in the column direction are based on the number of half columns, i.e. twice the number of columns in the matrix, and the control lines in the row direction are reduced to the number of the matrix.

- the optical fibers of a sub-matrix can be combined to form an optical fiber bundle and at the same time illuminated by a corresponding filter.
- the light exit end of each optical fiber can be covered and released by means of a flap, so that the image partial point with the assigned color can be included in the display or eliminated from the display.
- the partial image point b1 white, the partial pixel b2 yellow, the partial pixel b3 green and the partial pixel red are examples of the partial image point b1 white, the partial pixel b2 yellow, the partial pixel b3 green and the partial pixel red.
- This arrangement of a matrix point mp is repeated over all columns x1 to xn and over all rows y1 to ym.
- the columns x1 to xn are divided into half columns x11, x12 to xn1, xn2 with assigned control lines and the lines y1 to ym into half lines y11, y12 to ym1, ym2 with assigned control lines.
- the control information present or supplied in the display control device ASt corresponds to the display information, the value "0" meaning a covered optical fiber and the value "1 indicating an enabled optical fiber.

- the display control device ASt positions the partial display information in the assigned field B1, B2, B3, B4 ... of the matrix M. This process is repeated until the text letter by letter in the matrix M in the corresponding fields B1, B2, B3, B4 ... is set.
- FIG. 5 shows the electrical structure of a matrix point mp (x1, y1) with the four electromagnets Kx11y11, Kx12y11, Kx11y12 and Kx12y12 of the flaps. These electromagnets of the flaps are connected with the one connections to the assigned control lines of the half columns x11 and x12. The respective other connections lead via two rectifiers Ds and Dr to the set line and the reset line of the assigned half line y11 and y12.
- the electromagnet Kx11y11 of the flap is the half column x11 and the half line y11, the electromagnet Kx12y11 of the flap of the half column x12 and the half line y11, the electromagnet Kx11y12 of the half column x11 and the half line y12 and the electromagnet Kx12y12 of the flap of the half column x12 and the half line y12 assigned.
- the half line y11 has a set line y11 s and a reset line y11 r and the half line y12 has a set line y12s and a reset line y12r.
- Each set line y11 s or y12s is assigned a set switch shz1 or shz2, which connects the set potential + to the set line y11 s or y12s via the rectifier Ds.
- the selected half column x11 or x12 is switched to the setting reference potential ground via setting switch shsp1 or shsp2.
- Each reset line y11 r or y12r is assigned a reset switch rhz1 or rhz2, which connects the reset reference potential ground to the reset line rhz1 or rhz2 via the rectifier Dr.
- the selected half column x11 or x12 is switched on to the reset potential + via a reset switch rhsp1 or rhsp2.
- the rectifiers Ds and Dr are switched on so that when setting or resetting the current flow in one direction or the other flows over the electromagnet of the flap. A brief impulse is sufficient. The flap is then held in the set position by remanence until the electromagnet is actuated in the other direction of the current.
- the control cycle can be done in two ways. So the setting and resetting can include a separate cycle. Before a new display information is set, all flaps are reset to the cover position. This is done by applying the reset potential + to the half-columns x11, x12 to xn1, xn2 in succession via their reset switches rhsp1 and rhsp2. Each time a half column x11, x12 to xn1, xn2 is actuated, all reset lines y11 and y12r are always supplied with reset reference potential ground via the reset switches rhz1 and rhz2. This will reset all the flaps in the selected half column to their cover positions in one step.
- the flaps can be set from half column to half column in accordance with the display information according to FIG. 4 in a setting cycle.
- the information assigned to the matrix point mp (x1, y1) will lead to the setting of the electromagnet Kx11y12 of the assigned flap when the half-column x11 is activated and to the setting of the electromagnet Kx12y11 of the assigned flap when the half-column x12 is activated.
- all partial display information Tlnf of the display information is transferred into the half columns x11, x12 to xn1, xn2 of the matrix M.
- the assigned flaps release the partial pixels and the matrix M shows the corresponding display.
- the partial pixels of each matrix point mp can be set as desired or not set.
- the set cycle and the reset cycle can also be nested.
- the half column x11, x12 to xn1, xn2 is first reset in a first sub-step and then set in accordance with the assigned part display information Tlnf.
- This has the advantage that the half column x11, x12 to xn1, xn2 only has to be addressed once.
- the resetting and setting process is repeated until the cycle on the last half column x11, x12 to xn1, xn2 is completed and ended. New display information is then overwritten from half column to half column.

Abstract
Description
Die Erfindung betrifft eine Anzeigevorrichtung nach dem Oberbegriff des Anspruches 1.The invention relates to a display device according to the preamble of
Eine Anzeigevorrichtung dieser Art ist durch die DE 89 13 499 U1 bekannt. Bei dieser bekannten Anzeigevorrichtung sind verschachtelten Einzelmatrizen eigene Teil-Steuereinrichtungen zugeordnet, denen von einer Zentralsteuerung Teil-Anzeigeinformationen zugeführt werden. Aus den Teil-Anzeigeinformationen wird die Anzeigeinformation zusammengesetzt. Die Teil-Steuereinrichtungen steuern dabei die zugeordneten Teil-Bildpunkte über eigene Steuerleitungen an.A display device of this type is known from DE 89 13 499 U1. In this known display device, nested individual matrices are assigned their own part control devices, to which part display information is supplied by a central control. The display information is composed of the partial display information. The sub-control devices control the assigned sub-pixels via their own control lines.
Diese Art der Steuerung einer Matrix mit vier ineinander verschachtelten Teilmatrizen erfordert nicht nur einen hohen Steuerungsaufwand, sondern auch eine aufwendige Verdrahtung der Matrix. Außerdem ist die Einstellung der Matrix nur dann schnell, wenn die Teil-Steuereinrichtungen parallel alle zu setzenden Teil-Bildpunkte ansteuern. Dies bringt aber einen hohen Aufwand an Setzschaltern in den Teil-Steuereinrichtungen, da für jeden Teil-Bildpunkt ein eigener Setzschalter vorzusehen ist.This type of control of a matrix with four nested sub-matrices not only requires a high level of control effort, but also complex wiring of the matrix. In addition, the setting of the matrix is only quick if the partial control devices control all partial pixels to be set in parallel. However, this entails a high outlay on set switches in the partial control devices, since a separate set switch must be provided for each partial pixel.
Aus der DE 40 24 499 C1 ist eine Schaltungsanordnung für eine Anzeigevorrichtung mit einer Matrix aus bistabilen Matrixpunkten bekannt, bei der zum Überprüfen die Spalten bzw. die Zeilen nacheinander angesteuert werden, wobei stets alle Matrixpunkte der Spalte bzw. jeder Zeile gesetzt oder zurückgesetzt werden. Mit dieser Schaltungsanordnung kann aber keine Anzeige gesetzt und gelöscht werden, da in der Regel bei einer Anzeige nur ein Teil der Matrixpunkte einer Spalte bzw. Zeile gesetzt wird. Außerdem kann bei der Anzeige ein Matrixpunkt nur in einer Farbe wiedergegeben werden.From DE 40 24 499 C1, a circuit arrangement for a display device with a matrix of bistable matrix points is known, in which the columns or the rows are controlled one after the other for checking, wherein all matrix points of the column or each row are always set or reset. With this circuit arrangement, however, no display can be set and deleted since, as a rule, only part of the matrix points of a column or row are set in a display. In addition, a matrix point can only be reproduced in one color.
Es ist Aufgabe der Erfindung, eine Anzeigevorrichtung der eingangs erwähnten Art zu schaffen, bei der mit wesentlich reduziertem Aufwand für die Steuerung die gewünschte Anzeige sehr schnell und verschiedenfarbig dargestellt werden kann.It is an object of the invention to provide a display device of the type mentioned in the introduction, in which the desired display can be displayed very quickly and in different colors with significantly reduced effort for the control.
Diese Aufgabe wird nach der Erfindung einmal dadurch gelöst, daß in Spaltenrichtung die Elektromagnete der Klappen mittels einer Spaltensteuereinrichtung halbspaltenweise nacheinander ansteuerbar sind, wobei jeweils in einem ersten Teilschritt an die angesteuerte Halbspalte das Rücksetzbezugspotential und in einem zweiten Teilschritt das Setzbezugspotential anschaltbar ist, und daß in Zeilenrichtung die Elektromagnete der Klappen mittels einer Zeilensteuereinrichtung parallel ansteuerbar sind, wobei im ersten Teilschritt einer Spaltenansteuerung jeweils an alle Halbzeilen das Rücksetzpotential und im zweiten Teilschritt der Spaltenansteuerung jeweils die der angesteuerten Halbspalte entsprechende Teil-Anzeigeinformation als Setzpotential an die jeweils zugeordneten Halbzeilen anschaltbar ist, oder in gleich vorteilhafter Weise dadurch, daß in Spaltenrichtung die Elektromagnete der Klappen mittels einer Spaltensteuereinrichtung halbspaltenweise nacheinander ansteuerbar sind, wobei in einem Rücksetzzyklus an die angesteuerte Halbspalte jeweils das Rücksetzbezugspotential und bei jeder Spaltenansteuerung jeweils an alle Halbzeilen mittels einer Zeilensteuereinrichtung gleichzeitig das Rücksetzpotential anschaltbar ist, und daß in einem Setzzyklus mittels der Spaltensteuereinrichtung die Elektromagnete der Klappen halbspaltenweise nacheinander mit Setzbezugspotential ansteuerbar sind, wobei bei jeder Spaltenansteuerung jeweils die der angesteuerten Halbspalte entsprechende Teil-Anzeigeinformation als Setzpotential an die zugeordneten Halbzeilen anschaltbar ist.This object is achieved according to the invention in that the electromagnets of the flaps can be controlled one after the other in the column direction by means of a column control device, the reset reference potential in each case in a first sub-step and the set reference potential in a second sub-step, and that in In the row direction, the electromagnets of the flaps can be controlled in parallel by means of a row control device, the reset potential being able to be switched to all half rows in the first partial step of a column control and the partial display information corresponding to the controlled half column being set to the respective assigned half rows as setting potential in the second partial step, or in the same advantageous manner in that the electromagnets of the flaps can be controlled one after the other in the column direction by means of a column control device, wherein the reset reference potential in each case in a reset cycle to the controlled half-column and the reset potential can be switched on at the same time on all half-rows in each column control by means of a line control device, and that in a setting cycle by means of the column control device the electromagnets of the flaps can be controlled one after the other with set reference potential, with each column control in each case, the partial display information corresponding to the controlled half column can be connected to the assigned half lines as setting potential.
Durch die Aufteilung der Matrixpunkte in Halbspalten und Halbzeilen lassen sich mit entsprechend vorgegebenen halbspaltenweisen Teil-Anzeigeinformationen alle Teilmatrizen in einem Ansteuerzyklus einstellen. Dabei sind die Steuerleitungen in Spaltenrichtung auf die Anzahl der Halbspalten, d.h. die doppelte Anzahl der Spalten der Matrix, und die Steuerleitungen in Zeilenrichtung auf die Anzahl der Matrix reduziert. In Spaltenrichtung arbeitet die Ansteuerung seriell und in Zeilenrichtung parallel, so daß sowohl das Setzen als auch das Rücksetzen der Teil-Bildpunkte sehr schnell erfolgen kann, zumal die Setz- und Rücksetzimpulse nur wenige Millisekunden anstehen müssen, um die Klappen zu betätigen.By dividing the matrix points into half columns and half rows, all partial matrices can be set in one control cycle with the corresponding half-column partial display information. The control lines in the column direction are based on the number of half columns, i.e. twice the number of columns in the matrix, and the control lines in the row direction are reduced to the number of the matrix. In the column direction, the control works in series and in the row direction in parallel, so that both the setting and the resetting of the partial pixels can take place very quickly, especially since the set and reset pulses only have to be present for a few milliseconds to actuate the flaps.
Der Aufbau der Matrix ist nach einer Ausgestaltung so ausgeführt, daß jede Halbzeile sowohl eine Rücksetzleitung als auch eine Setzleitung aufweist, daß jede Rücksetzleitung über für das Rücksetzpotential durchlässige Gleichrichter mit den einen Anschlüssen aller Elektromagnete der Klappen der zugeordneten Halbzeile verbunden ist, daß jede Setzleitung über für das Setzpotential durchlässige Gleichrichter mit den einen Anschlüssen aller Elektromagnete der Klappen der zugeordneten Halbzeile verbunden ist, daß die anderen Anschlüsse der Elektromagnete der Klappen an zugeordnete Halbspaltenleitungen angeschaltet sind, und daß die Spaltensteuereinrichtung halbspaltenindividuelle Rücksetzschalter und halbspaltenindividuelle Setzschalter und die Zeilensteuereinrichtung halbzeilenindividuelle Rücksetzschalter und halbzeilenindividuelle Setzschalter aufweisen.The structure of the matrix is designed in such a way that each half line has both a reset line and a set line, that each reset line is connected to the one connections of all the electromagnets of the flaps of the assigned half line via rectifiers that are permeable to the reset potential, so that each set line has a rectifier permeable to the setting potential is connected to the one connections of all the electromagnets of the flaps of the assigned half row, that the other connections of the electromagnets of the flaps are connected to assigned half column lines, and that the column control device half-column-specific reset switches and half-column-individual reset switches and the row control device half-line individual reset switches and half-line switches exhibit.
Die Spaltensteuereinrichtung und die Zeilensteuereinrichtung sind von einer Anzeigesteuereinrichtung, z.B. einem Prozessor, ansteuerbar, der die Anzeigeinformation aus einem Speicher in Form von halbspaltenindividuellen Teil-Anzeigeinformationen zuführbar ist.The column controller and the row controller are from a display controller, e.g. a processor, which can be supplied with the display information from a memory in the form of half-column-specific partial display information.
Für die Anzeige eines Textes ist vorzugsweise vorgesehen, daß der Speicher die Anzeigeinformation in Halbspalten und Halbzeilen als Werte "0" und "1 enthält, wobei der Wert "1 das Setzen der zugeordneten Klappe in die Freigabestellung bedeutet.For the display of a text, it is preferably provided that the memory contains the display information in half columns and half rows as values "0" and "1, the value" 1 setting the assigned flap means in the release position.

Wie der Fig. 1 zu entnehmen ist, wird einer Matrix M mit Matrixpunkten mp aus vier verschiedenfarbigen Teil-Bildpunkten eine Spaltensteuereinrichtung SpSt und eine Zeilensteuereinrichtung ZSt zugeordnet. Eine zentrale Anzeigesteuereinrichtung ASt steuert die Spaltensteuereinrichtung SpSt und die Zeilensteuereinrichtung ZSt. Über eine Eingabe EG wird vorgegeben, welche Anzeigeinformation mit der Matrix M angezeigt werden soll. Verschiedene Anzeigeinformationen sind in einem Speicher ZSp gespeichert. Dabei kann über einen Textspeicher TxSp auch ein bestimmter Text ausgewählt werden. Der Speicher ZSp setzt dann die Buchstaben des Textes in Teil-Anzeigeinformationen um und plaziert diese in die in der Matrix M vorgegebenen Felder.As can be seen from FIG. 1, a column control device SpSt and a row control device ZSt are assigned to a matrix M with matrix points mp consisting of four differently colored partial picture elements. A central display control device ASt controls the column control device SpSt and the row control device ZSt. An input EG specifies which display information is to be displayed with the matrix M. Various display information is stored in a memory ZSp. A specific text can also be selected using a TxSp text memory. The memory ZSp then converts the letters of the text into partial display information and places them in the fields specified in the matrix M.
In Fig. 2 ist der Aufbau der Matrix M schematisch dargestellt. Jeder Teil-Bildpunkt des Matrixpunktes mp weist eine Lichtleitfaser auf, die entsprechend der der Teilmatrix zugeordneten Farbe beleuchtet wird. Die Lichtleitfasern einer Teilmatrix können zu einem Lichtleitfaser-Bündel zusammengefaßt und gleichzeitig über ein entsprechendes Filter beleuchtet werden. Das lichtaustrittsseitige Ende jeder Lichtleitfaser ist mittels einer Klappe abdeckbar und freigebbar, so daß der Bild-Teilpunkt mit der zugeordneten Farbe in die Anzeige einbezogen oder aus der Anzeige eliminiert werden kann .So kann, wie Fig. 3 schematisch zeigt, der Teil-Bildpunkt b1 weiß, der Teil-Bildpunkt b2 gelb, der Teil-Bildpunkt b3 grün und der Teil-Bildpunkt rot sein. Diese Anordnung eines Matrixpunktes mp wiederholt sich über alle Spalten x1 bis xn und über alle Zeilen y1 bis ym. Für die Steuerung werden die Spalten x1 bis xn in Halbspalten x11, x12 bis xn1, xn2 mit zugeordneten Steuerleitungen und die Zeilen y1 bis ym in Halbzeilen y11, y12 bis ym1, ym2 mit zugeordneten Steuerleitungen aufgeteilt.The structure of the matrix M is shown schematically in FIG. Each partial pixel of the matrix point mp has an optical fiber which is illuminated in accordance with the color assigned to the partial matrix. The optical fibers of a sub-matrix can be combined to form an optical fiber bundle and at the same time illuminated by a corresponding filter. The light exit end of each optical fiber can be covered and released by means of a flap, so that the image partial point with the assigned color can be included in the display or eliminated from the display. Thus, as shown schematically in FIG. 3, the partial image point b1 white, the partial pixel b2 yellow, the partial pixel b3 green and the partial pixel red. This arrangement of a matrix point mp is repeated over all columns x1 to xn and over all rows y1 to ym. For the control, the columns x1 to xn are divided into half columns x11, x12 to xn1, xn2 with assigned control lines and the lines y1 to ym into half lines y11, y12 to ym1, ym2 with assigned control lines.
Die in der Anzeigesteuereinrichtung ASt anstehende oder zugeführte Steuerinformation entspricht der Anzeigeinformation, wobei der Wert "0" eine abgedeckte Lichtleitfaser und der Wert "1 eine freigegebene Lichtleitfaser bedeutet. Der Aufbau der Steuerinformation entspricht mit den Spalten x1 bis xn und den Halbspalten x11, x12 bis xn1, xn2 sowie mit den Zeilen y1 bis ym und den Halbzeilen y11, y12 bis ym1, ym2 dem Aufbau der Matrix M. Eine Halbspalte x11, x12 bis xn1, xn2 bildet eine Teil-Anzeigeinformation Tlnf, die parallel in die zugeordnete Halbspalte x11, x12 bis xn1, xn2 der Matrix M übertragen wird.The control information present or supplied in the display control device ASt corresponds to the display information, the value "0" meaning a covered optical fiber and the value "1 indicating an enabled optical fiber. The structure of the control information corresponds to the columns x1 to xn and the half columns x11, x12 to xn1, xn2 and with the lines y1 to ym and the half lines y11, y12 to ym1, ym2 the structure of the matrix M. A half column x11, x12 to xn1, xn2 forms part of the display information Tlnf, which is parallel to the assigned half column x11, x12 to xn1, xn2 of the matrix M is transmitted.
Wie Fig. 4 zeigt, kann die Anzeigeinformation wie die Matrix M in gleich große Felder B1, B2, B3, B4 ... aufgeteilt sein. Die Felder B1, B2, B3, B4 ... sind so groß, daß ein Buchstabe eines Textes dargestellt werden kann. Wird mit dem Textspeicher TxSp ein bestimmter Text vorgegeben, dann kann mit Hilfe des Speichers ZSp Buchstabe für Buchstabe des Textes in die entsprechende Teil-Anzeigeinformation umgesetzt werden. Die Anzeigesteuereinrichtung ASt positioniert die Teil-Anzeigeinformation in das zugeordnete Feld B1, B2, B3, B4 ... der Matrix M. Dieser Vorgang wiederholt sich solange, bis der Text Buchstabe für Buchstabe in der Matrix M in den entsprechenden Feldern B1, B2, B3, B4 ... gesetzt ist.As FIG. 4 shows, the display information, like the matrix M, can be divided into fields B1, B2, B3, B4 ... of the same size. The fields B1, B2, B3, B4 ... are so large that a letter of a text can be displayed. If a certain text is specified with the text memory TxSp, the memory ZSp can be converted letter by letter of the text into the corresponding partial display information. The display control device ASt positions the partial display information in the assigned field B1, B2, B3, B4 ... of the matrix M. This process is repeated until the text letter by letter in the matrix M in the corresponding fields B1, B2, B3, B4 ... is set.
Fig. 5 zeigt den elektrischen Aufbau eines Matrixpunktes mp (x1, y1) mit den vier Elektromagneten Kx11y11, Kx12y11, Kx11y12 und Kx12y12 der Klappen. Diese Elektromagnete der Klappen sind mit den einen Anschlüssen an den zugeordneten Steuerleitungen der Halbspalten x11 und x12 angeschaltet. Die jeweils anderen Anschlüsse führen über jeweils zwei Gleichrichter Ds und Dr an die Setzleitung und die Rücksetzleitung der zugeordneten Halbzeile y11 bzw. y12. Der Elektromagnet Kx11y11 der Klappe ist der Halbspalte x11 und der Halbzeile y11, der Elektromagnet Kx12y11 der Klappe der Halbspalte x12 und der Halbzeile y11, der Elektromagnet Kx11y12 der Halbspalte x11 und der Halbzeile y12 sowie der Elektromagnet Kx12y12 der Klappe der Halbspalte x12 und der Halbzeile y12 zugeordnet.5 shows the electrical structure of a matrix point mp (x1, y1) with the four electromagnets Kx11y11, Kx12y11, Kx11y12 and Kx12y12 of the flaps. These electromagnets of the flaps are connected with the one connections to the assigned control lines of the half columns x11 and x12. The respective other connections lead via two rectifiers Ds and Dr to the set line and the reset line of the assigned half line y11 and y12.

Die Halbzeile y11 hat eine Setzleitung y11 s und eine Rücksetzleitung y11 r und die Halbzeile y12 eine Setzleitung y12s und eine Rücksetzleitung y12r. Jeder Setzleitung y11 s bzw. y12s ist ein Setzschalter shz1 bzw. shz2 zugeordnet, der über den Gleichrichter Ds das Setzpotential + an die Setzleitung y11 s bzw. y12s anschaltet. Während des Setzens ist die ausgewählte Halbspalte x11 bzw. x12 über Setzschalter shsp1 bzw. shsp2 an das Setzbezugspotential Masse angeschaltet.The half line y11 has a set line y11 s and a reset line y11 r and the half line y12 has a set line y12s and a reset line y12r. Each set line y11 s or y12s is assigned a set switch shz1 or shz2, which connects the set potential + to the set line y11 s or y12s via the rectifier Ds. During the setting, the selected half column x11 or x12 is switched to the setting reference potential ground via setting switch shsp1 or shsp2.
Jeder Rücksetzleitung y11 r bzw. y12r ist ein Rücksetzschalter rhz1 bzw. rhz2 zugeordnet, der über den Gleichrichter Dr das Rücksetzbezugspotential Masse an die Rücksetzleitung rhz1 bzw. rhz2 anschaltet. Während des Rücksetzens ist die ausgewählte Halbspalte x11 bzw. x12 über einen Rücksetzschalter rhsp1 bzw. rhsp2 an das Rücksetzpotential + angeschaltet. Die Gleichrichter Ds und Dr sind so eingeschaltet, daß beim Setzen bzw. Rücksetzen der Stromfluß in der einen bzw. anderen Richtung über den Elektromagneten der Klappe fließt. Es genügt dabei ein kurzzeitiger Impuls. Die Klappe wird dann solange durch Remanenz in der eingestellten Stellung gehalten, bis die Ansteuerung des Elektromagneten in der jeweils anderen Stromrichtung erfolgt.Each reset line y11 r or y12r is assigned a reset switch rhz1 or rhz2, which connects the reset reference potential ground to the reset line rhz1 or rhz2 via the rectifier Dr. During the reset, the selected half column x11 or x12 is switched on to the reset potential + via a reset switch rhsp1 or rhsp2. The rectifiers Ds and Dr are switched on so that when setting or resetting the current flow in one direction or the other flows over the electromagnet of the flap. A brief impulse is sufficient. The flap is then held in the set position by remanence until the electromagnet is actuated in the other direction of the current.
Der Steuerzyklus kann auf zwei Arten erfolgen. So kann das Setzen und Rücksetzen einen eigenen Zyklus umfassen. Vor dem Setzen einer neuen Anzeigeinformation werden alle Klappen in die Abdeckstellung zurückgestellt. Dies erfolgt dadurch, daß die Halbspalten x11, x12 bis xn1, xn2 nacheinander über ihre Rücksetzschalter rhsp1 bzw. rhsp2 mit dem Rücksetzpotential + beaufschlagt werden. Bei jeder Ansteuerung einer Halbspalte x11, x12 bis xn1, xn2 werden stets alle Rücksetzleitungen y11 bzw. y12r über die Rücksetzschalter rhz1 bzw. rhz2 mit Rücksetzbezugspotential Masse beaufschlagt. Damit werden alle gesetzten Klappen der ausgewählten Halbspalte in einem Schritt in ihre Abdeckstellungen zurückgestellt. Ist der Rücksetzzyklus durchgeführt, dann können in einem Setzzyklus die Klappen entsprechend der Anzeigeinformation nach Fig. 4 von Halbspalte zu Halbspalte gesetzt werden. Die dem Matrixpunkt mp (x1, y1) zugeordnete Information wird bei der Ansteuerung der Halbspalte x11 zum Setzen des Elektromagneten Kx11y12 der zugeordneten Klappe und bei der Ansteuerung der Halbspalte x12 zum Setzen des Elektromagneten Kx12y11 der zugeordneten Klappe führen. Nach dem Setzzyklus sind alle Teil-Anzeigeinformationen Tlnf der Anzeigeinformation in die Halbspalten x11, x12 bis xn1, xn2 der Matrix M übertragen. Die zugeordneten Klappen geben die Teil-Bildpunkte frei und die Matrix M zeigt die entsprechende Anzeige. Dabei können die Teil-Bildpunkte jedes Matrixpunktes mp beliebig gesetzt oder nicht gesetzt werden.The control cycle can be done in two ways. So the setting and resetting can include a separate cycle. Before a new display information is set, all flaps are reset to the cover position. This is done by applying the reset potential + to the half-columns x11, x12 to xn1, xn2 in succession via their reset switches rhsp1 and rhsp2. Each time a half column x11, x12 to xn1, xn2 is actuated, all reset lines y11 and y12r are always supplied with reset reference potential ground via the reset switches rhz1 and rhz2. This will reset all the flaps in the selected half column to their cover positions in one step. If the reset cycle has been carried out, the flaps can be set from half column to half column in accordance with the display information according to FIG. 4 in a setting cycle. The information assigned to the matrix point mp (x1, y1) will lead to the setting of the electromagnet Kx11y12 of the assigned flap when the half-column x11 is activated and to the setting of the electromagnet Kx12y11 of the assigned flap when the half-column x12 is activated. After the setting cycle, all partial display information Tlnf of the display information is transferred into the half columns x11, x12 to xn1, xn2 of the matrix M. The assigned flaps release the partial pixels and the matrix M shows the corresponding display. The partial pixels of each matrix point mp can be set as desired or not set.
Der Setzzyklus und der Rücksetzzyklus können auch ineinander verschachtelt werden. Bevor eine ausgewählte Halbspalte x11, x12 bis xn1, xn2 gesetzt wird, wird in einem ersten Teilschritt die Halbspalte x11, x12 bis xn1, xn2 erst zurückgesetzt und dann entsprechend der zugeordneten Teil-Anzeigeinformation Tlnf gesetzt. Dies hat den Vorteil, daß die Halbspalte x11, x12 bis xn1, xn2 nur einmal addressiert werden muß. Bei jeder neu ausgewählten Halbspalte x11, x12 bis xn1, xn2 wiederholt sich der Rücksetz- und der Setzvorgang, bis der Zyklus an der letzten Halbspalte x11, x12 bis xn1, xn2 vollzogen und beendet wird. Eine neue Anzeigeinformation wird dann von Halbspalte zu Halbspalte überschrieben.The set cycle and the reset cycle can also be nested. Before a selected half column x11, x12 to xn1, xn2 is set, the half column x11, x12 to xn1, xn2 is first reset in a first sub-step and then set in accordance with the assigned part display information Tlnf. This has the advantage that the half column x11, x12 to xn1, xn2 only has to be addressed once. With each newly selected half column x11, x12 to xn1, xn2, the resetting and setting process is repeated until the cycle on the last half column x11, x12 to xn1, xn2 is completed and ended. New display information is then overwritten from half column to half column.
