<p>A deflection yoke for a color cathode ray tube includes a saddle shaped vertical deflection coil and a saddle shaped horizontal deflection coil. The horizontal deflection coil (3) includes winding turns forming a pair of side portions (120, 120', 121, 121') having a winding window (18) therebetween extending free of conductor wires. The side portion has a winding space for correcting corresponding portions of coma and convergence errors. A corner portion (17) of the winding space is disposed iin a Z-axis coordinate selected in a range between a Z-axis coordinate, defining the end of the window that is close to the electron gun of the tube, and a third Z-axis coordinate, closer to the screen of the tube. The length of the range may be approximately 10 % of a length of the window. Correction of convergence error, horizontal coma error or coma parabola error may be obtained without using field shapers such as shunts or magnets.</p> |
