Deflection unit for color television display tubes |
摘要 |
A deflection unit for in-line color television display tubes having a line deflection coil and a field deflection coil, the field deflection winding having a slightly pronounced barrel-shaped field deflection field in the middle and on the screen side of the deflection unit and being combined with field-forming means (in particular soft-magnetic segments which are placed between the line and field deflection coils) to generate a pronounced pin-cushion-shaped field on the gun side of the deflection unit. As a result of these measures, the deflection unit couples a coma-free field deflection field with a minimum EW-field distortion.
