Abstract
The turn-off period of the FET (111) is adjusted by changing the output pulse width of the MM (113) according to the horizontal deflection frequency, to adjust the total capacitance value of the S-shape correcting capacitor group in one horizontal deflection period, that is, to execute an optimum S-shape distortion correction according to each horizontal deflection frequency. The timing at which the electronic switch element (111) is turned off in a first half of the horizontal scanning period is continuously and variably controlled on the basis of an external control signal (Vg). The auxiliary S-shape correcting capacitor (110) of the S-shape correcting capacitor group is controllably turned on or off by the electronic switch element (111), to execute an optimum S-shape distortion correction.
