Abstract
A deflection yoke for a CRT (cathode ray tube), including a flat wire to compensate for the convergence and upper and lower raster distortions of the electron beams, thereby forming images of high quality, and a method of making the deflection yoke. The deflection yoke has a horizontal coil adjacent the cathode ray tube, a vertical coil at least partially surrounding a ferrite core, a holder between the horizontal and vertical coils for electrically insulating the horizontal and vertical coils from one another, and a flat wire coupled to the holder for correcting convergence errors.
