摘要： A color display device including a shadow mask and a correction deflection system for correcting landing-errors. The correction deflection system comprises first and second correction deflection devices which are arranged one behind the other in the direction of the electron beams and are energizable in opposite senses so that the first correction deflection device generates a dipole field deflecting the three electron beams away from the longitudinal tube axis, and the second correction deflection device generates a dipole field deflecting the three electron beams towards the longitudinal tube axis, or conversely.

摘要： Convergence correction device for a color display tube comprising a rolled-up flexible support provided with two convergence correction coil systems at its inner surface as well as its outer surface. The coils of each system are of the spiral-shaped type and are interconnected via metallized apertures by means of an electrically conducting strip at the opposite circumferential surface. Dependent on the specific configuration, the flexible support is wound once or twice around the neck of the display tube.

摘要： Display tube including a convergence correction device which comprises a plurality of correction coils having coplanar axes and being arranged around the tube neck. The coils are of the planar type. More specifically, there are two sets of four coils for generating two differently oriented four-pole fields and two sets of six coils for generating two differently oriented six-pole fields, while all these coils are arranged on one flexible support which is wound around the tube neck a number of times, for example, one set of coils for each turn.

摘要： A deflection unit comprising a set of preformed diametrical deflection coils. A hollow coil support of synethic material includes at least two lugs into which respective permanent deformations are impressed. The coils are mechanically anchored to the lugs by means of, for example, an ultrasonic welding process in which the locations of the coil support situated opposite supported locations of the coils are softened and pressed into the coils. The coils substantially free of the coil support, i.e., the larger part of each coil is free of the coil support, and are not deformed so that their mutual position is accurately maintained.

摘要： Display tube comprising a deflection unit provided with a (twist) correction device which includes an annular (twist) correction coil surrounding the tube neck, which coil, when energized by a circuit providing a (twist) correction current, generates a magnetic correction field in the axial direction of the display tube. According to the invention, the device also provides a 4-pole y field for correcting (twist) errors in the center of the display screen. This 4-pole y field can be generated by causing the turns of the annular coil to follow a path having four predetermined corrugations alternately facing the display screen and the electron gun.
