Color cathode ray tube having a low dynamic focus voltage

摘要

A color cathode ray tube has an electron gun, a main lens for focusing said plurality of electron beams on said phosphor screen, at least one multipole lens located between said main lens and said beam forming region, and at least one correction lens wherein at least one of said at least one multipole lens and said at least one correction lens has an electrode constitution in which trajectories of outer electron beams among said plurality of electron beams are deflected one of toward and away from a trajectory of a center electron beam among said plurality of electron beams according to an increase in an amount of deflection of said plurality of electron beams. <IMAGE>
