Abstract
Refinements introduced in a color television display system comprising: a color television image tube that includes a face plate that has deposited on it groups of three different elements of color luminescent material that form an image screen, characterized by a set of electron beam guns to produce three electron beams lying in a horizontal plane substantially perpendicular to said image display and a perforated mask including a plurality of apertures coincident with said groups of elements of luminescent material, said set of electron beam guns being selected to produce said three beams along three generally converging lines extending towards said image screen; and a deflection coil comprising vertical and horizontal deflection windings arranged around said imaging tube between said mask and said set of barrels to deflect said rays in order to form a pattern on said image screen, the distribution of windings being selected. of said deflection windings to produce vertical positive isotropic astigmatism and horizontal negative isotropic astigmatism, so that said rays are made to overconverge along the vertical axis of the frame and are subconverted along the horizontal axis thereof; said set of electron ray guns being further selected to produce a separation of not more than 5.08 mm between the adjacent rays of said rays, measured in a plane located halfway between the ends of said coil.
