摘要： In an electron gun for a color cathode ray tube apparatus of this invention, one intermediate electrode is arranged between a final acceleration electrode and a focus electrode that make up a main lens, and a voltage divided by a voltage dividing resistor for dividing a voltage to be applied to the final acceleration electrode is applied to the intermediate electrode. A dynamic voltage which increases along with an increase in deflection amount of an electron beam is applied to the focus electrode, and a dielectric portion is formed between the final acceleration electrode and the focus electrode. This dielectric portion is formed on the intermediate electrode. Hence, elliptical distortion of electron beam spots is decreased on the entire surface of a phosphor screen, thereby providing a color cathode ray tube apparatus with a good performance on the entire surface of the phosphor screen.

摘要： In a self-convergent type color cathode ray tube apparatus, three in-line electron beams emitted from an electron gun assembly are deflected by non-uniform magnetic fields generated by a deflection yoke and thus self-converged onto a screen. The electron gun assembly has a second grid and a third grid. First and second auxiliary grids are disposed between the second and third grids. A dynamic voltage varying in synchronism with deflection of the electron beams is applied to the first auxiliary grid situated on the second grid side. A fixed voltage is applied to the second auxiliary grid situated on the third grid side. Accordingly, the second grid, the first and second auxiliary grids and the third grid form an electron lens such that a higher astigmatism is provided by focusing in a direction perpendicular to a direction of arrangement of the three electron beams than by focusing in the direction of arrangement of the three electron beams and the degree of the astigmatism is dynamically varied. A color cathode ray tube apparatus capable of performing uniform focusing over the entire screen with a relatively low dynamic voltage is provided.

摘要： A main lens is formed by a focus electrode, an intermediate electrode, and an anode electrode successively arranged in a traveling direction of an electron beam. The focus electrode and the anode electrode respectively have an electron beam passage aperture co mmon to three electron beams, having a major axis in a horizontal direction in a portion opposed to the intermediate electrode, and three electron beam passage apertures through which the three electron beams pass are formed respectively in the focus electrode and the anode electrode. Aperture dimensions in a vertical direction of the electron beam passage apertures common to the three electron beams formed respectively in the focus electrode and the anode electrode are smaller than those in the vertical direction of the electron beam passage apertures formed in portions of the intermediate electrode respectively opposed to the focus electrode and the anode electrode. This can provide a color Braun tube apparatus that has less moire while having satisfactory focus performance over the entire surface of a phosphor screen, and in which there are no increase in the cost of a driving circuit and the decrease in withstand voltage characteristics.

摘要： An electron gun assembly in a cathode-ray tube apparatus includes a quadrupole lens that is created in accordance with deflection of electron beams. The quadrupole lens is created by two mutually opposing grids. The two grids have non-circular electron beam passage holes in their mutually facing surfaces. Each electron beam passage hole has a waist portion which minimizes a horizontal or vertical dimension of a region for passing the associated electron beam.

摘要： An in-line type electron gun using a field superimposing type main lens system is provided that can attain good focusing properties by decreasing the size of the electron beam spot on the entire surface of the phosphor screen without being formed to be mechanically large. A field superimposing type main lens is formed by disposing two tubular electrodes opposite to each other and disposing a plate-like field correction electrode on each of the tubular electrodes on the sides not opposite to each other. On each of the opposite sides of the two tubular electrodes, an opening is formed by an edge portion and a folded portion. The shape of the opening may be an elongated flat-sided oval shaped aperture (laterally elongated aperture) that is formed by straight lines and semicircles and has a major diameter in the horizontal direction and a minor diameter in the vertical direction. The in-line type electron gun is configured such that a relationship B

摘要： An electron gun assembly forms an electron beam generator, pre-focusing lens, sub-lens, and main lens. The sub-lens has a weaker horizontal focusing power than the vertical one, and the main lens has a stronger horizontal focusing power than the vertical one. When the electron beam is not deflected, a first quadrupole lens is formed between the pre-focusing lens and sub-lens, and a second quadrupole lens is formed between the sub-lens and-main lens. At least one grid forming each of the first and second quadrupole lenses receives a dynamic focusing voltage which parabolically changes in synchronism with the deflection magnetic field and becomes higher when the electron beam is deflected than when it is not deflected.

摘要： An electron gun comprises a supplementary grid applied with a voltage which dynamically changes in synchronization with a magnetic field generated by a deflection yoke, between a second grid and a third grid. Further, by the second grid, the supplementary grid, and the third grid, an electron is constructed which has an astigmatic aberration in which a focusing force in the horizontal direction is stronger than a focusing force in the vertical direction. The intensity of the astigmatic aberration of the electron lens is dynamically changed by a voltage applied to the supplementary grid.
