ABSTRACT:
The invention is a color cathode-ray tube having a rectangular front face connected to a funnel shaped rear part, a neck connected to the rear part and having an electron gun therein, the gun is used to generate beams intended to scan the front face under the influence of a deflection device placed on the neck of the tube. The deflection device comprising correction magnets placed on the periphery of the device in locations closest to the front face and a magnetic screen within the tube having an opening for passage of the electron beams, wherein the opening has notches in its periphery. The notches are arranged so as to face at least one pair of correction magnets.
