CONVERGENCE DRIFT IMPROVING METHOD FOR COLOR CATHODE-RAY TUBE

摘要

The method gets rid of the major problem in the color cathode ray, the convergence drift, which is the irregular formation of the electric field. The method comprises the induction scheme which enforces the electric field be uniform around the surface of neck; the decentralization step the ununiform electric field formed the inside neck (N); and the selected material from graphite or aluminum.
