  • Electron gun for color picture cathode-ray tube with hexagonal cross-section
    Patent number: 5196762
    Abstract: An electron gun for a color picture cathode-ray tube which includes a main focusing lens of a large diameter for reducing deterioration of the focusing property caused by the spherical aberration of the main focusing lens, shortening the distances among three electron beams to minimize the deflection aberration from deflection yoke and making feasible a design for effective enlargement of the lens diameter even with the shortening of the distances among the three electron beams in the color picture cathode-ray tube requiring a good focusing property of the three beams.
