摘要:
An in-line type cathode ray tube apparatus, is improved to obtain less aberration of beam spots by shaping the electron beam passing apertures (15a, 15b, 15c) in the control grid (11) and those in the accelerating grid (12) into horizontally oblong elliptic shapes, and providing a horizontally oblong electrode means (18) having a rectangle shape active space on the accelerating grid (12) at its down stream side of the electron beam.
