摘要： The present invention provides a color cathode ray tube which can make the focusing of a center electron beam and side electron beams uniform by reducing the non-uniformity of the spot shape of electron beams depending on a deflection quantity. The second electrode G2 includes three electron beam apertures made of one center electron beam aperture and two side electron beam apertures which are arranged in an in-line array. Each one of three electron beam apertures is formed of a rectangular recessed portion which has long sides in an in-line direction and a circular aperture which penetrates a center portion of the rectangular recessed portion. The depth of the recessed portion arranged at the center electron beam aperture is set larger than the depth of the recessed portions arranged at side electron beam apertures.

The electron beam generating unit includes a cathode, a first grid electrode and a second grid electrode, and the main lens unit is formed of plural electrode members and a final accelerating electrode disposed downstream thereof and supplied with a high voltage. A final main lens is formed between the final accelerating electrode and one of the electrode members adjacent thereto. An electrostatic quadrupole lens is formed in a first space between adjacent ones of the electrode members, one of which is supplied with a first focus voltage of a fixed value, another of which is supplied with a second focus voltage synchronized with electron beam deflection, wherein the first and second focus voltages are higher than a second grid electrode voltage. The quadrupole lens focuses the electron beams horizontally and vertically and diverges them horizontally and vertically depending upon which is the higher of the first and second focus voltages. A third electrostatic lens is disposed between the final main lens and the quadrupole lens and formed in a second space between adjacent ones of the electrode members, one of which is supplied with the first focus voltage, and another of which is supplied with the second focus voltage, and the third electrostatic lens decreases horizontal and vertical focusing actions on the electron beams with increasing electron beam deflection.

摘要： A color cathode ray tube includes an in-line electron gun having a main lens with recessed apertures. The main lens is formed by two electrodes. These electrodes have outer edges and recessed apertures which allow passage of three in-line electron beams and which are arranged at a distance d1 and d2, respectively, from the outer edges. The outermost apertures are asymmetric. The difference d1-d2 and the asymmetry of the outermost apertures is such that both the beam displacement and the core haze asymmetry are minimal.

摘要： In a color cathode ray tube apparatus of this invention, an electron beam forming unit of an electron gun outputs electron beams to have an interval of 3.5 to 6.0 mm between adjacent beams, and a ratio of a neck inner diameter to the interval between the adjacent electron beams is 5.1 or more. The main lens unit of the electron gun has a large-aperture electron lens formed by a substantially cylindrical first electrode for allowing three electron beams to pass therethrough, and a substantially cylindrical second electrode in which most of the first electrode is arranged.

摘要： The astigmatism of the electron beams (6, 7, 8) generated by an electron gun system (5) are substantially reduced by constructing the lens electrode components (25, 26) between which a focusing lens is formed in an operating electron gun to be inverted replicas of each other. The lens electrode components should be provided with the corresponding sides (45, 46) facing each other and with the corresponding apertures (38, 42) opposite to each other.
