APPARATUS FOR CORRECTING MIS-CONVERGENCE AND GEOMETRIC DISTORTION IN DEFLECTION YOKE USING VARIABLE RESISTANCE

摘要

PROBLEM TO BE SOLVED: To easily adjust the VCR by adjusting the current flowing in a comma- free coil using a variable resistance instead of attaching a magnetic member as in the conventional method, with respect to a deflection yoke, in particular, a product for needing a variable VCR(Vertical Center Raster) characteristic (Vertical Green characteristic). ;SOLUTION: The apparatus of this invention includes a coil separator, an upper horizontal deflection coil, a lower horizontal deflection coil, a left vertical deflection coil, a right vertical deflection coil, a ferrite core, a comma-free coil, a distortion adjustment section, a first convergence adjustment section, a second convergence adjustment section, and a VCR mis-convergence adjustment section.;COPYRIGHT: (C)2003,JPO
