DISPLAY APPARATUS COMPRISING A CATHODE RAY TUBE (CRT)

摘要

A display apparatus, for instance a television receiver, comprises a cathode ray tube (3), a first circuit (1) for providing a high voltage (HV) to the cathode and a second circuit (2) receiving a gross signal (Y') and providing on at least an output at least a luminance signal (Y) controlling an electron stream of the cathode ray tube (3). To reduce stray emission, absence of gross signal (Y') is simulated when the apparatus is switched from on to off.
