摘要： A cathode ray tube having an electron gun assembly in which a plurality of electrodes constitute an electron beam generating unit for generating electron beams, and an electron lens unit for focusing the generated beams on a predetermined location on a phosphor screen. The electron gun assembly further contains a pair of insulating support rods for supporting the electrodes, a resistor unit for applying a voltage to at least one of the electrodes. A metal ring is mounted in contact with a predetermined electrode of the electron lens unit and surrounds the insulating support rods. Terminal voltage pickup terminals apply a voltage to the resistor unit. At least a first and second intermediate voltage pickup terminal supply a voltage from the resistor unit to a first and second electrode. The first and second intermediate voltage pickup terminals are located in relation to the metal ring such that a discharge is prevented and image quality is preserved.

摘要： In a electron gun assembly, three in-line electron beams are generated from three cathodes and are controlled and accelerated by a prefocusing electron lens, and each of the electron beams is converged by unipotential electron lens. In a horizontal plane, the electron beams are collimated by a quadruple lenses and are incident on a single and common large-diameter main electron lens. In a vertical plane, each of the electron beams is emerged as a divergent electron beam from the quadruple lens and each of the divergent electron beams is incident on the main electron lens. Thus, each of the electron beams are correctly focused on a screen and the three electron beams are correctly converged on a convergent point by the main electrode lens.

摘要： An electron gun for a color-picture tube includes adjacent low and high potential electrodes composing an electron lens, which electrodes have electron beam path holes horizonally formed with electric-field correcting members or raised portions. According to this construction, vertical equipotential lines are projected into the electrode so that the low potential electrode adds to electron beams a vertical focusing effect more strongly than a horizontal one and the high potential electrode adds to electron beams a vertical divergent effect more strongly than a horizontal one. The section of the electron beam in a deflection region has an ellipse shape whose major axis extends horizontally, resulting in suppressing a halo portion on the screen. The electron beam is properly focused horizontally and vertically so that the electron beam spot has a circular shape on the center of a screen. It results in improving the resolution on the periphery of the screen without having to lower the resolution on the center of the screen.
