Title: Mask focusing color picture tube
Inventor: KANBARA EIJI
IPC: H01J29/07
Filed: 1981-06-24
Abstract: PURPOSE:To increase the practical use of a mask-focusing color picture tube by obtaining beams with a small distortion over the entire screen by making a central axis connecting corresponding apertures of masks, which parallel face the screen, to correspond to the central axis of an electron beams deflected with a deflecting part. CONSTITUTION:The central axis connecting the center of an aperture 22 of a mask 8 on the electron gun side and the center of a corresponding aperture 23 of a mask 7 on the screen side corresponds to the central axis of an incoming electron beams 15. Therefore, the aperture pitch of the mask 8 and the aperture pitch of the mask 7 are set differently. As the result, a almost all of the electron beam 15, after passing through the aperture 22 of the mask 8, passes through the aperture 23 of the mask 7 while receiving lens effect, and bumps against the surface of a screen 1. Here, since the lens effect of the electron beams 15 developing between the masks 7 and 8 becomes almost symmetrical relative to the axis of the beams 15, the shape of the beam bumping against the screen 1 can have no extreme distortions.
