Abstract
A color picture reproducing tube utilizes three coplanar electron beams. Convergence of the three beams along at least one axis is accomplished by a deflection assembly producing a magnetic deflection field with particular astigmatism characteristics which also elliptically distorts each of the three beams in a first direction. The electron gun assembly within the picture tube includes apertured electrodes which predistort the beams elliptically in a second direction orthogonal to the first direction of distortion.
