Claims (4)
- 유리네크와 이 유리 네크내에 설치된 전자총 장착 어셈블리를 구비하는 음극선관으로서, 상기 전자총 장착 어셈블리가 적어도 하나의 전자빔을 발생시키는 수단과 종방향으로 연장하는 적어도 2개의 절연성 지지 비이드의 하나의 주표면에 고정된 스크린 그리드 전극, 집속 전극 및 양극 전극으로 구성되어 연속적으로 이격되게 배치된 복수의 전극을 포함하며, 상기 각 비이드의 반대쪽 주표면은 외측으로 향하고 그 표면상 상기 집속 전극에 대향하여 위치 설정된 전기 전도성 코팅이 배치되며, 상기 전자총 장착 어셈블리내에서 상기 비이드를 따라 전기적 작용을 발생시키기 위해 상기 전극에 적당한 전압을 인가하는 수단을 포함하는 음극선관에 있어서, 상기 각각의 비이드(23a,23b)상에 설치된 상기 코팅(43a,43b)은 종방향 치수 d를 갖고 상기 비이드를 따라 전기적 작용이 최소인 영역에 위치 설정되며, 상기 코팅의 중심은 상기 스크린 그리드 전극(29)에 인접한 상기 집속 전극(31)의 단부로부터 약 1.25d의 거리만큼 종방향으로 이격되어 배치되는 것을 특징으로 하는 음극선관.
- 제1항에 있어서, 상기 전도성 코팅(43a, 43b)은 원형인 것을 특징으로 하는 음극선관.
- 제2항에 있어서, 상기 전도성 코팅(43a, 43b)의 치수 d는 약 6.4mm(1/4인치)인 것을 특징으로 하는 음극선관.
- 제1항 또는 제2항에 있어서, 상기 전도성 코팅(43a, 43b)은 전기적으로 플로우팅 상태에 있는 것을 특징으로 하는 음극선관.
