Magnetically Improved Color Alignment of CRT's

A 50% reduction of convergence errors of CRT's is achieved by a technique referred to as 'Magnetically Improved Color Alignment' or MICA for short. The MICA technology comprises a ring of synthetic material (polymer) filled with ferrite particles. MICA is meant for repairing CRT's, which are out of convergence specification. The repairing occurs by writing a magnetic correction profile in the ring.
