Abstract
A display monitor which comprises a flyback transformer for supplying a high voltage to a display and an opposite-phase pulse inducing transformer. The flyback transformer includes a core, a primary-side low-voltage coil wound on the core, a secondary-side high-voltage coil wound on the core and divided into high-voltage coil pieces, rectifier diodes connected in series with respective output sides of the high-voltage coil pieces of the secondary-side high-voltage coil so as to form a series circuit, and a high-voltage capacitor connected to a cathode of one of the high-voltage rectifier diodes in a final stage of the series circuit. The opposite-phase pulse inducing transformer is constituted by a core different from the core of the flyback transformer, an opposite-phase pulse inducing coil wound on the different core for inducing a pulse which is opposite in phase to a deflecting yoke driving horizontal pulse, and a different-core high-voltage output line provided on the different core, the opposite-phase pulse inducing transformer being arranged so that the pulse opposite in phase to the deflecting yoke driving horizontal pulse is superimposed on the different-core high-voltage output line.
