    摘要： The novel CRT has an electron gun mount assembly (21) therein which includes a cathode (25) for generating at least one electron beam and a plurality of successively spaced electrodes, including a screen grid electrode (29), a focusing electrode (31) and an anode electrode (33), secured to one major surface of at least two longitudinally extending insulating support beads (23a,23b). A first gap (57) of predetermined width extends between the anode electrode and one end of the focusing electrode. A second gap (59) of predetermined width extends between the opposite end of the focusing electrode and the screen grid electrode. An opposite major surface of each of the support beads faces outwardly and has thereon an electrically-conducting coating (43a,43b) having a longitudinal dimension, d. Suitable voltages are applied to the electrodes to generate electrical activity. The coating on each of the beads is spaced a distance of about 1.25 x d from the end of the focusing electrode adjacent to the second gap.

    摘要： According to the present invention, there is provided an in-line type color CRT electron gun (26) comprising a triode (28a, 28b, 28c, 31, 32) and a plurality of grids (33, 34, 35, 36), characterized in that at least one of the plurality of grids (33, 34, 35, 36) is made of a black member or a member on which a black film is formed. According to the present inven­tion, the time required for attaining a stable tem­perature of the member is reduced, thereby improving deviations in static convergence and reducing the time required for an image to be normally displayed.
