10.2.1979 1 PHN 9215 ABSTRACT By deflecting the electron beams before the focusing lenses in an electron gun system for a colour display tube towards the tube axis by non-symmetrical lens fields so that they converge on the display screen, it has proved possible to obtain symmetrical focusing lens fields by means of mechanically non-symmetrical elec- trodes the axes of which are parallel, if the beams en- close a given angle with the gun axes. This enables an easy manufacture of the electrodes and an accurate assem- bly of the guns. In these guns the focusing of the beams is independent of the convergence.
