Abstract

An image reproduction arrangement with two pairs of deflection coils, one each for the horizontal and vertical deflection of electron beams in a television picture tube. This deflection unit comprises two additional pairs of coils (2, 3) set at an angle of 90<o>, which permit an additional video frequency deflection of the electron beams in a horizontal and a vertical direction. The additional pairs of coils (2, 3) are printed on a strip of film (1) which is wound about the neck (4) of the television picture tube.

Description

Bildwiedergabeanordnung Image display arrangement

Die Erfindung geht aus von einer Bildwiedergabeanordnung mit einer ein Elektronenstrahlerzeugersystem beinhaltenden Bildröhre, deren Elektronenstrahlen von einer aus mehreren Wicklungen bestehenden Ablenkeinheit zur Wiedergabe eines Bildes in vertikaler und horizontaler Richtung ablenkbar sind.The invention is based on a picture display device with a a picture tube containing an electron gun, whose electron beams from a deflection unit consisting of several windings to reproduce a Image are deflectable in the vertical and horizontal directions.

Es ist bereits bekannt, zur Verbesserung der Bildqualität die Elektronenstrahlen zusätzlich zur bildfrequenten und zeilenfrequenten Ablenkung abzulenken. So ist es z.B. bekannt, die Ablenkgeschwindigkeit der Elektronenstrahlen in horizontaler Richtung mit Hilfe des differenzierten Videosignals zu beeinflussen, wodurch Helligkeitssprünge auf dem Bildschirm schärfer werden. Auch ist es bekannt, die Elektronenstrahlen in vertikaler Richtung zusätzlich abzulenken, um z.B. das Zwischenzeilenflimmern bei der Wiedergabe von eingeblendeten Zeichen (BTX oder Videotext) zu beseitigen. Die Zusatzablenkung wurde dabei mit Hilfe der Hauptablenkspulen erzielt. Wenn nun jedoch eine videofrequente Zusatzablenkung gefordert wird, sind die Hauptablenkspulen wegen ihres grossen L/R-Verhältnisses und wegen ihrer Wicklungskapazitäten nicht geeignet, da sie zu träge sind.It is already known to use electron beams to improve image quality distract in addition to frame rate and line rate distraction. So is For example, it is known the deflection speed of electron beams in the horizontal To influence the direction with the help of the differentiated video signal, whereby jumps in brightness sharper on the screen. It is also known to use electron beams in the vertical direction additionally to deflect, for example, the interline flicker during playback of superimposed characters (BTX or teletext). The additional deflection was achieved with the help of the main deflection coils. If now However, an additional video frequency deflection is required, are the main deflection coils not because of their large L / R ratio and because of their winding capacities suitable because they are too sluggish.

Der Erfindung liegt die Aufgabe zugrunde, eine Ablenkeinheit dahingehend zu verbessern und zu erweitern, daß mit dieser auch sehr schnelle Ablenkänderungen erzielt werden können. Diese Aufgabe wird durch die im Patentanspruch angegebene Maßnahme gelöst. Vorteilhafte Weiterbildungen der Erfindung sind aus den Unteranansprüchen entnehmbar.The invention is based on the object of a deflection unit to this effect to improve and expand that with this also very quick diversion changes can be achieved. This task is given by the claim Measure solved. Advantageous further developments of the invention can be found in the subclaims removable.

Nachstehend wird die Erfindung an einem Ausführungsbei -spiel mit Hilfe der Zeichnung erläutert.The invention is illustrated below using an exemplary embodiment Explained with the help of the drawing.

Figur 1 zeigt die Spulenanordnung; Figur 2 zeigt die Spulenanordnung in Verbindung mit der Bildröhre.Figure 1 shows the coil arrangement; Figure 2 shows the coil arrangement in connection with the picture tube.

Wegen der geringen Ablenkleistung kann der Querschnitt der Zusatzspulen klein sein. Die Strahlsysteme in einer Farbfernsehbildröhre liegen in einer horizontalen Ebene.Because of the low deflection power, the cross-section of the additional coils be small. The beam systems in a color television picture tube are horizontal Level.

Daraus ergibt sich, daß die Zusatzablenkspulen für die waagrechte Ablenkrichtung eine größeren Umfangswinkel des Röhrenhalses umschließen müssen als die Zusatzspulen für die vertikale Ablenkrichtung. Die Zusatzspulen für die horizontale Ablenkrichtung befinden sich oberhalb und unterhalb des Elektronenstrahlsystems. Die Zusatzspulen für die vertikale Ablenkrichtung befinden sich entsprechend an der rechten und linken Seite neben den Elektronenstrahlsystemen. Wesentlich ist, daß zur Vermeidung von Konvergenzfehlern sämtliche Elektronenstrahlen in gleichem Maße abgelenkt werden. Daher darf der Umfassungswinkel der Zusatzspulen nicht zu klein sein. Besonders günstig ist es, wenn für jedes Spulenpaar eine Folienlage vorgesehen wird. Die komplette Spulenanordnung kann dann mit doppelter Umschlingung des Röhrenhalses aufgebaut sein, wobei sich die beiden Spulenpaare teilweise überlappen können.It follows that the additional deflection coils for the horizontal Deflection direction must enclose a larger circumferential angle of the tube neck than the additional coils for the vertical deflection direction. The additional coils for the horizontal The deflection direction are above and below the electron beam system. The additional coils for the vertical deflection direction are located accordingly the right and left side next to the electron beam systems. What is essential is that to avoid convergence errors all electron beams in the same Dimensions are distracted. Therefore, the circumferential angle of the additional coils must not be too be small. It is particularly advantageous if a film layer is used for each coil pair is provided. The complete coil arrangement can then be wrapped around twice of the tube neck, with the two pairs of coils partially overlapping can.

In der Zeichnung ist ein Folienstreifen 1 gezeigt, dessen Länge etwa dem doppelten Umfang des Röhrenhalses entspricht. Auf diesem Folienstreifen 1 ist kaschiert das Spulenpaar 2 für die vertikale sowie das Spulenpaar 3 für die horizontale Ablenkrichtung vorgesehen. Sie besitzen einen derartigen Abstand voneinander, daß bei Umschlingung des Folienstreifens 1 um den Röhrenhals die Spulenpaare 2 bzw. 3 an den entsprechenden Stellen wie oben angegeben anliegen. Dabei können die Leitungen der Spulenpaare 2 und 3 auf je einer Seite des Folienstreifens 1 aufgedruckt sein. Es ist auch denkbar, daß die Spulenpaare 2 und 3 auf den Röhrenhals direkt aufgedampft sind.In the drawing, a film strip 1 is shown, the length of which is approximately corresponds to twice the circumference of the tube neck. On this film strip 1 is hides the coil pair 2 for the vertical and the coil pair 3 for the horizontal Deflection direction provided. They have such a distance from each other that When wrapping the film strip 1 around the tube neck, the coil pairs 2 or 3 in the appropriate places as indicated above. The lines of the coil pairs 2 and 3 be printed on each side of the film strip 1. It is also conceivable that the coil pairs 2 and 3 are vapor-deposited directly onto the tube neck are.

Die Spulenpaare können auch als Drahtwicklungen ausgebildet sein, die zwischen dem zylindrischen Teil des Bildröhrenhalses bis in den konischen Teil der Bildröhre hineinreichend zwischen den Hauptablenkwicklungen und der Glaswand der Bildröhre angeordnet sind.The coil pairs can also be designed as wire windings, between the cylindrical part of the picture tube neck and into the conical part of the picture tube reaching between the main deflection windings and the glass wall the picture tube are arranged.

In Figur 2 ist gezeigt, wie der Folienstreifen 1 mit den Spulenpaaren 2 und 3 um den Bildröhrenhals 4 gewickelt ist.In Figure 2 it is shown how the film strip 1 with the coil pairs 2 and 3 is wrapped around the picture tube neck 4.
