  • Patent number: 4665347
    Abstract: In picture-reproducing equipment with higher scanning frequencies (e.g., flicker-free television, visual display unit), the generation of the horizontal-deflection current is separated in frequency from the generation of the operating voltages by supplying the horizontal-deflection circuit from a DC voltage source which is part of the voltage power supply providing the operating voltages. The supply circuit is preferably connected to the grounded deflection capacitor. This makes it possible to influence the picture geometry in a simple manner, particularly to perform horizontal pincushion correction.
