The horizontal output circuit of a monitor comprises: a horizontal oscillating section for generating pulses by an oscillator; a first field effect transistor connected to the output of the horizontal oscillating section with its gate, grounded at its source, and switched on/off based on the output waveform of the horizontal oscillating section; a photo coupler connected to the output of the horizontal oscillating section and for introducing the output waveform of the horizontal oscillating section to a secondary stage; and a second field effect transistor connected to the secondary stage of the photo coupler with its gate, connected to the drain of the first field effect transistor with its source, connected to a horizontal deflection yoke with its drain, and switched on/off by a voltage introduced to the secondary stage of the photo coupler and a synthesized voltage applied to the drain of the first field effect transistor, so as to supply a voltage to the deflection yoke. |
