ABSTRACT:
A display device is described, comprising a display tube and a deflection unit. The high DC voltage (EHT) is generated by a line output transformer, this transformer receiving the flyback pulse during the line flyback period. This flyback pulse is transferred through the line output transformer and supplied as the high DC voltage (EHT) to the inner coating of the display tube. Variation of the high DC voltage causes radiation in front of the display tube. To overcome this radiation, a conductor is coupled between the ground terminal (or a metal shield coupled to the ground terminal) of the line output transformer and the outer coating of the display tube. This conductor has at least one turn around one of the coils of the deflection unit for generating a complementary variation to overcome the radiation in front of the display tube.
