Definitions

  • the invention is based on an image display device with a picture tube containing an electron beam generating system, the electron beams of which can be deflected in a vertical and horizontal direction by a deflection unit consisting of several windings for reproducing an image.
  • the main deflection coils are not suitable because of their large L / R ratio and because of their winding capacities, since they are too slow.
  • the object of the invention is to improve and expand a deflection unit in such a way that very fast deflection units can also be achieved with it. This object is achieved by the measure specified in the claim.
  • Figure 1 shows the coil arrangement
  • Figure 2 shows the coil arrangement in connection with the picture tube.
  • the cross section of the additional coils can be small.
  • the beam systems in a color television picture tube lie in a horizontal plane. It follows from this that the additional deflection coils for the horizontal deflection direction have to enclose a larger initial angle of the tube neck than the additional coils for the vertical deflection direction.
  • the additional coils for the. horizontal deflection are located above and below the electron beam system.
  • the additional coils for the vertical deflection direction are located on the right and left side next to the electron beam systems. It is essential that all electron beams are deflected to the same extent in order to avoid convergence errors. Therefore, the peripheral angle of the additional coils must not be too small. It is particularly favorable if a film layer is provided for each pair of coils.
  • the complete coil arrangement can then be doubled. Be wrapped around the neck of the tube, being. the two pairs of coils can partially overlap.
  • a film strip 1 is shown, the length of which corresponds approximately to twice the circumference of the tube neck.
  • the coil pair 2 for the vertical and the coil pair 3 for the horizontal deflection direction is laminated on this film strip 1. They are at such a distance from one another that when the film strip 1 is wrapped around the tube neck, the pairs of coils 2 and 3 rest against the corresponding points as indicated above.
  • the lines of the coil pairs 2 and 3 can be printed on one 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.
  • the pairs of coils can also be designed as wire windings, which are arranged between the cylindrical part of the picture tube neck and into the conical part of the picture tube extending between the main deflection windings and the glass wall of the picture tube.
  • FIG. 2 shows how the film strip 1 is wound around the picture tube neck 4 with the pairs of coils 2 and 3.

Abstract

Agencement pour reproduction d'images comportant deux paires de bobines de balayage, respectivement une paire pour le balayage horizontal et une paire pour le balayage vertical des faisceaux électroniques dans un tube image de télévision. Cette unité de balayage comprend deux paires supplémentaires de bobines (2, 3) décalées de 90o, qui permettent un balayage supplémentaire à fréquences vidéos des faisceaux électroniques dans un sens vertical et horizontal. Les paires supplémentaires de bobines (2, 3) sont imprimées sur une bande de film (1) enroulée autour du col (4) du tube image.
