摘要： A color picture tube device that can adjust convergence without causing increases in cost and in power consumption is provided. One pair of magnetic flux generation means for generating a static quadrupole magnetic field are positioned above and below an area where a plurality of electron beams pass through. The static quadrupole magnetic field has an effect of adjusting convergence in a horizontal direction. In this construction, a magnetic flux generated by one of the two magnetic flux generation means that is closer to the plurality of electron beams is reduced, in sync with deflection of the plurality of electron beams in a vertical direction.

摘要： A color display device having a color display tube with a display screen, comprising an electron gun for generating three co-planar electron beams, and a deflection system which, in operation, generates deflection fields for scanning the display screen, and an element influencing the landing angle of the outermost beams, for example an element generating, in operation, a 45° magnetic 4-pole field, and comprising a correction device which supplies a signal to the element influencing the landing angle, which signal is derived from the video information (for example a signal which is proportional to the strength of the instantaneous beam current) in order to remedy landing errors caused by space-charge repellence between beams.

摘要： A color cathode ray tube using a self-convergence method is provided with magnets for correcting top/bottom pincushion distortion, and includes a vertical deflection coil and a four-pole coil. The vertical deflection coil generates a first correction field distorted in a barrel shape. The four-pole coil is arranged on the side of a deflection yoke nearer to an electron gun, and corrects YH barrel pattern misconvergence by generating a second correction field. The strength of the second correction field varies according to the amount of vertical deflection applied to electron beams emitted by the electron gun.

摘要： L'assemblage décrit (110) qui comprend quatre languettes séparées (110a'-d') est utilisé pour produire, à partir d'un flux de champ magnétique de dispersion, un champ en forme de coussinet dans une partie du col d'un tube à rayon cathodique (100) qui est disposé à l'arrière d'un joug déflecteur (10), afin d'assurer une correction de coma de convergence verticale. Des bobines (140a-d), enroulées autour des languettes (110a'-d') forment un électro-aimant quadripôle, lequel assure également une correction de convergence dynamique.

摘要： There is disclosed a cathode-ray tube which employs an electron gun assembly of the laminar flow (LF) type (20, 21, 22). The beam emanating from the LF electron gun assembly is directed through a three-electrode einzel lens assembly (30, 31, 32) where the center electrode of the einzel lens assembly is subjected to a modulation voltage. Positioned after the einzel lens assembly are magnetic deflection circuits which include a horizontal (41) and vertical (42) coil enabling the beam to deflect in the horizontal and vertical directions and which circuits are positioned internally within the CRT. A convergence assembly is also built within the neck of the CRT. Thus, the CRT provides the advantages of the laminar flow gun while enabling modulation of the electron beam to provide an extremely small spot size to enable the CRT to operate with small spot size and to provide more efficient deflection at higher modulation rates.
