<p>PROBLEM TO BE SOLVED: To provide a cheap display monitor with the easiness of a high-voltage insulation, a favorable handling quality and a reduced alternating electric field, by superimposing a deflection yoke driving horizontal pulse and an anti-phase pulse to it on a separate-core high-voltage output wire through an anti-phase pulse induction transformer. SOLUTION: Winding a separate-core high-voltage output wire 22 on an anti-phase pulse inducing separate core 23 with a wound anti-phase pulse induction coil 24 thereon, or passing the output wire 22 through the hollow portion of the core 23, an anti-phase induction transformer 31 is formed. Adjusting by an anti-phase pulse controlling circuit 25 the peak value and phase of the anti-phase pulse generated in a tertiary-side anti-phase pulse generating coil 4 of an FBT 1, the resultant anti-phase pulse is applied to the primary side of the anti-phase pulse induction transformer 31. Thereby, on the separate-core high-voltage output wire 22, a deflection yoke driving horizontal pulse and the anti-phase pulse to it are superimposed.</p> |
