摘要： A dual direction horizontal bi-directional scan circuit, in which the deterioration of the picture quality is prevented effectively, while the linearity is improved without supplying wasteful deflecting current and the pin distortion is corrected. The deflecting current in the going scan and in the returning scan are supplied to each deflecting coil by a first and second resonance circuit, and the capacitor being much the same in capacitance is provided to the first and second resonance circuit to bias the deflecting voltage so that the terminal voltage and the power source voltage of this capacitor is synchronized to the vertical synchronizing signals to modulate in a parabolic shape.

摘要： At a horizontal deflecting circuit of bi-directional deflection, timings of deflection of forward scan path along a backward scan path are respectively controlled. The timing of deflection along forward path or backward path is controlled at the first timing control circuit 22 so that it is synchronized with the horizontal synchronizing signal HD and timing of deflection along backward path or forward path is controlled at the second timing control circuit 24 so that deflection cycles of forward path and backward path are equalized. Further, timings of deflection of forward scan path and backward scan path are controlled respectively at first and second phase comparison circuits 22 and 24 so that the relation in phase between the image signal and the deflection takes a constant value on the basis of the horizontal synchronizing signal, to previously prevent occurrence of steady phase error.

摘要： A horizontal deflection circuit is provided in which a large retrace pulse voltage applied to a horizontal deflection yoke (4) can be taken to reduce the deflection current and which is capable of easily performing horizontal image size adjustment and distortion adjustment. A parallel connection of a switching element (11), a damper diode (12), and a resonance capacitor (13) is connected in series to a parallel connection of another switching element (21), another damper diode (22), and another resonance capacitor (23), and power is supplied from the connection point via a fly-back transformer (6). The comparison value of the retrace pulse voltages applied across both ends of the switching elements (11,21) is fed back through a switching element control circuit (40) to one of the switching elements (21) so that the deflection current of the horizontal deflection yoke (4) is controlled.
