发明名称 Color display tube including cylindrical dipole correction magnets
摘要 If in a device for displaying colored pictures comprising a color display tube of the "in-line" type, which comprises magnetized means for maintaining a static magnetic multipole magnetic field near the output of the electron gun system for carrying out static beam corrections, a correction magnet is provided outside the neck near the output of the electron gun system and near at least one outermost electron beam, which magnet forms a magnetic dipole and is intersected by the said plane and which correction magnet is small with respect to its distance to said electron beam, it is possible afterwards to provide small corrections in the horizontal static convergence.
