説明
Demands for higher image quality of color display monitors are increasing. In particular, color blurring caused by misconvergence of three electron beams is a major factor to he evaluated. The electron beams are deflected by magnetic field of a deflection yoke. Therefore, coils of the deflection yoke should be wound precisely, but it is not easily implemented due to many errors of winding wire, winding machine and forming control. From another point of view, we have proposed selective coupling of coils other than random coupling. Thus for selecting similar coils and coupling them to compensate misconvergence, fast measuring and a method for coupling are required. Misconvergence estimation by calculation of beam trajectories takes a long time because of volumes of measurement data. To overcome these difficulties, we newly developed a method which is derived through multiple regression analysis between magnetic flux density distribution of a few intersection and miseonvergence. Furthermore, we have developed a new coupling method based on efficient coil categorization. In this paper, the new methods and the comparison between experiments and theoretical approaches are presented.
