DYNAMIC CONVERGENCE SYSTEM FOR COLOR CATHODE RAY TUBES HAVING AN IN LINE ELECTRON GUN

A color cathode ray tube equipped with an in-line type electron gun, a deflection yoke designed to generate a uniform deflection magnetic field, the in-line type electron gun having a focusing grid which accommodates three pole pieces of magnetic bodies, and a magnetic field generator disposed outside the cathode ray tube so as to apply 4-pole dynamic magnetic fields to the pole pieces, thus constituting a dynamic convergence system capable of correcting any misconvergence of the three electron beams in a vertical direction or a horizontal direction.
