Cathode Ray Tube Display with Cancellation of Electric Field Emissions

International Business Machines Corportation (1994) Cathode Ray Tube Display with Cancellation of Electric Field Emissions. .

Abstract

A cathode ray tube display having reduced electric field emissions comprising a cathode ray tube 100, an element 200 for detecting modulations in the final anode voltage of the CRT, the signal not being directly dependent on the deflection driving means 115. A matching network 205 provides phase and gain correction to the signal from element 200, amplification means 210 receives the signal from network 205 and an emission means 215 radiates a cancelling electric field dependent on the modulations detected by said element 200.
