Abstract

PURPOSE:To achieve right and left bobbin distortion corrections and to reduce raster distortion and inverse trapezoidal distortion by changing the discharge current of an S-shape correcting capacitor into parabola shape in the vertical period by means of a modulation source. CONSTITUTION:The voltage -VCs' across a second S-shape correction capacitor C's is discharged through a modulation source A, then the voltage VCs across a first S-shape correction capacitor Cs, becomes lower, accordingly, a horizontal deflection current iy is also decreased. When said discharge current is decreased, the -VCs' rises, the VCs and the iy is also increased. Through above processing, a discharge current iD from the second S-shape correction capacitor C's is changed by the modulation source A into a parabola shape in the vertical period, so that the deflection current iy is also changed into a parabola shape in the vertical period in order to execute the right and left bobbin distortion correction. Furthermore, since no correction transformer is used, neither raster distortion nor inverse trapezoidal distortion will occur.
