Abstract

A device for correcting the non-coincidence of the rectangular image gratings of a tricolor television tube formed respectively by independent electronic beams swept on the screen of the tube by a deflection yoke disposed substantially coaxial with the axis of the tube and surrounding the electronic beams said beams being directed before scanning along respective trajectories substantially parallel to the axis of the tube and located equiangularly about said axis, one of said electronic beams being spaced in the direction of the tube axis parallel to one of the dimensions of the respective image grating of said beam, and each beam of radial movement relative to the axis of the tube being provided by means of dynamic beam convergence to keep the beams in substantial convergence on the screen of the tube during scanning, characterized by a Convergence correction device for proportion Matching on the screen of the image scans formed by the three electronic beams and including a structure for changing the position of the deflection yoke relative to the axis of the tube by rotating the deflection yoke about an axis normal to the direction in that said beam is spaced from the axis of the tube to make the image grating of said beam coincide with the image gratings of the other beams.
