Abstract: 757,193. Colour television tubes. CHROMATIC TELEVISION LABORATORIES, Inc. April 2, 1952 [April 4, 1951], No. 33668/54. Divided out of 757,071. Class 39 (1). A cathode-ray tube, especially a colourreceiving tube, comprises adjacent to the target or screen an electrode having a multiplicity of apertures, which electrode co-operates with a conductive layer on the target to form spherical electron lenses. In one form, Fig. 1, a lens electrode 65 with hexagonal apertures made of woven wire, or preferably of a perforated sheet, is spaced a small distance from a tri-colour fluorescent screen, the fluorescent areas 67R, 67B, 67G of which are rhomboidal in shape. The second lens electrode is a thin conductive electron permeable film coated on the phosphors and is kept positive to the first lens electrode so as to form approximately spherical lenses to focus the beam to a point. There may be one or three guns, the colour control deflections being accomplished before the electrons reach the spherical lens system. To avoid aberrations due to the lack of circular symmetry of the field to the hexagonal elements an arrangement of short cylinders 65<SP>11</SP>, Fig. 4, can be used. The second lens electrode is a conducting film on the fluorescent screen. The electrons may be focused to an area at the screen equal to 10 per cent of the area of an aperture in the first lens electrode. The preliminary focusing means comprises an electrostatic lens of short focal length in the gun, the electrons being refocused approximately in the plane of the screen by an electromagnetic lens of long focal length. A field, line, segment or dot sequential transmission system may be used.
