  • Patent number: 3975766
    Abstract: A color television receiver comprising a color television receiving tube which is provided with three horizontally arranged electron guns so designed as to emit three electron beams and cause said beams to be converged at a point outside of the fluorescent screen of the color television receiving tube; a deflection yoke fitted to the color television receiving tube and so constructed as to cause a horizontal deflection magnetic field created by said yoke to display a pincushion-shaped intensity distribution and a vertical deflection magnetic field produced thereby to present a barrel-shaped intensity distribution; and a delay circuit for causing at least two of the three primary color signals of color television which modulate the three electron beams to be successively delayed from the foremost one at the rate of a prescribed length of time corresponding to the intervening spacing of the three electron beams impinging on the fluorescent screen of the color television receiving tube.
