摘要： A focusing electrode in an electron gun for a color cathode ray tube or high definition industrial picture tube includes a first and second focusing electrodes. A recess portion in one end of the first focusing electrode is oriented to face burring parts of the second focusing electrode. An electron beam and a surrounding portion pass through holes in the first focusing electrode to reduce the space between the first and second focusing electrodes. This improves the static convergence drift.

摘要： An in-line electron gun for a color picture tube has an accelerating electrode portion separated into two or three electrodes in a triode, in which a voltage supplied to respective electrodes is varied and an asymmetrical hole is formed in at least one among the electrodes to form an additional asymmetric lens, thereby preventing degradation of a focus characteristic caused by an abrupt increase of a diverging angle of electron beam in a high current region, degradation in the vertical electron beam due to an influence of a magnetic field of a deflection yoke, change of focusing force induced by voltage variation of a first accelerating/focusing electrode, and degradation of the electron beam owing to collision/repulsion among electrons in the electron beam.

摘要： A Focusing electrode in an electron gun for a color cathode ray tube provides a higher degree of freedom in electron gun design and reduces errors during assembly of the electron gun. A first focusing electrode that receives a constant voltage has vertically elongated electron beam pass-through holes formed in it. A second focusing electrode that receives a dynamic voltage has electron beam pass-through holes that include a pair of burring parts formed on their upper and lower edges. The burring parts are disposed in each of the vertically elongated electron beam pass-through holes in the first focusing electrode without changing a horizontal diameter of the electron beam pass-through holes in the first focusing electrode.
