Abstract
Arc suppressor coating structures with enhanced limiting characteristics for color cathode ray tubes are achieved by employment of a high electrical resistance coating (30) having, in a specific area, an extremely high resistance (i.e., insulator) coating (46) thereon which provides a seating area for an antenna getter mounted upon the electron gun. The insulator coating is preferably comprised of about 71.2% Fe.sub.2 O.sub.3 and 28.2% K.sub.2 SiO.sub.3. Insulating the antenna getter from, the high resistance coating reduces electrical shorts and keeps arc currents within the range of less than 40 amps. Such results were not previously achievable with antenna getter usage.
