Claims (4)
- 디스플레이 윈도우(2); 코운(3); 네크(4) 및; 상기 디스플레이 윈도우(2)의 내부에 제공된 디스플레이 스크린(7)상에, 편향 코일(9)시스템의 편향 필드에 의해 실제로 상호 수직인 두 방향 X,Y으로 상기 디스플레이 스크린(7)에 대해 편향되어지는 스폿(8)을 형성하도록, 포커스되는 전자 빔(6)을 발생하는 전자 총(5); 으로 구성된 진공 상태의 엔벨로프의 네크부를 포함하는 디스플레이 튜브에 있어서, 상기 편향 코일(9)시스템의 전자 총측의 상기 편향 필드의 엣지 필드는 필드 세이퍼(27,28,29,30)에 의해 배럴형으로 만들어지는데, 상기 필드 세이퍼는 상기 전자빔(6) 주위에 배열되고 실제로 편향의 X,Y방향으로 상기 전자빔으로부터 떨어져 상기 빔을 확장하는 강자성물질로 된 4개의 판(27,28,29,30)을 포함하고 상기 전자 총(5)의 스크린에 면한 단부(10)에서 집중판(26)에 접속되며, 상기 판은 상기 스크린쪽으로, 상기 집중 판(26)으로부터 떨어져 확장하며, 상기 집중 판에 접속된 상기 판의 단부가 상기 전자총으로부터 실제로 동일한 거리에 배치되는 것을 특징으로 하는 디스플레이 튜브.
- 제1항에 있어서, 적어도 2개의 상기 판(51)의 단부가 상기 전자빔으로부터 떨어져 있고 편향방향으로 서로 연장선에 배치되고, 강자성 물질의 여분의 판(52,53)이 제공되어 형성되어질 상기 필드에 대해 실제로 수직으로 확장되는 것을 특징으로 하는 디스플레이 튜브.
- 제1항 또는 제2항에 있어서, 라인 편향 필드(27,29)용 필드 세이퍼는 필드 편향필드(28,30)용 필드 세이퍼보다 상기 전자 빔을 따라 더 먼거리까지 상기 전자총으로부터 확장되는 것을 특징으로 하는 디스플레이 튜브.
- 제1항 또는 제2항에 있어서, 상기 편향 방향으로 상기 전자빔으로부터 떨어져 확장된 상기 판이 슬롯을 포함하는 것을 특징으로 하는 디스플레이 튜브.
