摘要： The focusing characteristic of this electron gun is not impaired by the aberration caused by the deviation from the centers of the holes on both sides of the main lens, through which the electron beams pass, and the astigmatism of the electron beams due to the uneven magnetic field such of a deflecting yoke when the electron gun is in operation. In the focusing electrode 1 of the electron gun a assembly, a plurality of focusing grooves are formed parallel to the direction in which the electron beams pass. A plurality of additional electrode members, each consisting of a flat thin plate, are inserted into the focusing grooves, respectively.

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.

摘要： An electron gun body for a color cathode ray tube includes an electron beam forming region formed by cathodes, first and second grids, and a main focusing lens having first and second accelerating and focusing electrodes for substantially focusing three electron beams from the electron beam forming region. The first and second accelerating and focusing electrodes are provided with through holes for passing the three electron beams and upper rims respectively bent from the outer circumferences of the electrodes toward the through holes, in which a first inclined extension electrode having a vertically-provided sloped portion and bottom portion, and a center hole opened to reach a bent plane of the sloped portion in the bottom portion is installed into the first accelerating and focusing electrode to fix one side of the first inclined extension electrode to connect with an inwardly-bent portion of the one upper rim, and a second inclined extension electrode having projections parallel in both directions on the same plane of a head portion is installed into the second accelerating and focusing electrode, while forming the vertical inner diameter of the projection to be smaller than that of the upper rim, to fix one side of the second inclined extension electrode to connect with an inwardly-bent portion of the other upper rim. Thus, astigmatism is eliminated without using a separate correction electrode to improve resolution on the periphery of a screen.
