PURPOSE:To obtain a picture with high-grade quality without meander and color shifting by making vertical deflecting current flow into respective coil in series and making the induction of a horizontal pulse from a horizontal deflecting coil same size and reversed polarity in each deflection york. CONSTITUTION:The 1st red vertical deflecting coil part 3, the 1st blue vertical deflecting coil part 13 and the 1st green vertical deflecting coil part 8 are connected in series. The 2nd vertical deflecting coil parts 9, 14, 4 are connected in series in the order of green, blue and read. As the result, vertical deflecting current flows into each coil in series but, in case of the induction of a horizontal pulse from a horizontal deflecting coil, the size is the same and the polarity is reversed, so that the induction is cancelled in the deflection magnetic field and tortuosity does not generate in the picture. In addition, the difference of vertical amplitude of each cathode-ray tube does not generate, obtaining the high quality of a picture with no color shifting. |
