摘要： In-line electron guns for color picture tube improving the resolution of the color picture tube. The guns not only exhibit the special quality of a large aperture of lens but also achieve the desired mechanical strength of electrodes by arranging .OR right.-shaped inner electrode plates in the envelope electrodes respectively. Each of first and second accelerating/focusing electrodes for focusing three electron beams of the electron beam sources on the phosphor screen includes an envelope electrode and an electrostatic field control electrode placed in the envelope electrode. The envelope electrode includes a predetermined length of hollow envelope part and a predetermined width of rim part extending from an edge of the hollow envelope part. The electrostatic field control electrode includes a plate electrode sided by predetermined width of blades at opposed sides thereof. This blade sided plate electrode is holed at its center so as to have a center beam passing opening.

摘要： An electron gun for a color cathode-ray tube reducing the spherical aberration and the flying spot aberration, thus improving the resolution of the color cathode-ray tube. The electron gun comprises a pair of accelerating/focusing electrodes coaxial with the tube and providing a passage for the electron beams. The electrodes are spaced apart from each other by a predetermined distance and has individual common openings, and each includes an envelop having a rim adjacent a corresponding common opening, the rim surrounding the plurality of electron beams and defining the common opening, and a control electrode plate being placed in the envelop and recessed from the rim by a predetermined distance in the axial direction in order for controlling the plurality of electron beams. Each electrode plate has a center opening and a pair of opposed outer openings. The center opening may be a rectangular opening or rounded at its upper and lower ends. The outer openings are disposed at opposed sides of the center opening and each opening toward an inner surface of the envelop. The open space of the outer opening may be gradually enlarged toward the inner surface of the envelop.

摘要： An electron gun for a color picture tube comprising six spaced grid electrodes aligned in the direction that electron beams proceed. The fourth grid electrode comprises a pair of plate-shaped grid electrodes arranged to form a space therebetween and electrically connected with each other. Both plate-shaped grid electrodes are also connected with the second of the grid electrodes so that they receive the same voltage. The space defined between both plate-shaped grid electrodes is variable within the range corresponding to 0.29 to 1.15 times the thickness of each plate-shaped grid electrode. By the construction of the fourth grid electrode, the spaces defined between respective adjacent grid electrodes can be reduced. As a result, the generation of undesirable stray is restricted. Also, the kind of using electrodes can be widely selected, since the space defined between one side fourth grid electrode and the other side fourth grid electrode can be varied.
