PURPOSE: A circuit for compensating a straight line property of the S type of a horizontal deflection circuit is provided to reduce consumption power by using a push pull circuit instead of a plurality of FETs and condensers and embody the exact S curve and straight line property. CONSTITUTION: The circuit includes a horizontal oscillation portion(110), a horizontal drive portion(120), a horizontal output portion(130), a horizontal deflection yoke(H-DY), a compensating portion(140) of S type and a controlling portion(150). The horizontal oscillating portion generates a horizontal oscillation frequency by a horizontal synchronization signal being inputted and outputs. The horizontal driving portion is driven by an output signal of the horizontal oscillation portion to generate and output an amplified pulse wave form of the same frequency as a horizontal oscillation frequency. The horizontal outputting portion is driven by an output signal of the horizontal drive portion to supply a current to a horizontal deflection yoke. The horizontal deflection yoke receives an output current of the horizontal output portion and generates a sawtooth wave current. The compensating portion of S type consists of a push pull circuit which is in series connected to the horizontal deflection yoke and compensates the sawtooth wave current with S type. The controlling portion applies a parabolic synchronization signal to the compensating portion of S type.
