Claims (9)
- 배면부(4) 및 전면부를 갖는 진공 엔벨로프(1)를 포함하고, 상기 배면부에는 전자총 시스템(5)이 수용되어 있으며, 이 전자총 시스템을 이용하여 세 개의 전자빔 (6,7,8)을 발생시키되 이 전자빔의 축들이 한 평면내에 위치되도록 상기 세 개의 전자빔을 발생시키며, 상기 발생된 전자빔들은 표시윈도우(2) 내부에 제공된 표시 스크린 (10)상에서 집속렌즈에 의해 집속되며, 상기 집속렌즈는 표시 스크린으로부터 떨어져 있는 제1집속 전극(25)과, 표시 스크린과 직면하고 있는 제2집속 전극(26)을 포함하고, 상기 제1 및 제2집속 전극은 동작중에 제1접속 전압인가수단 및 고전압 인가수단에 각각 접속되어 있는 칼라 표시관에 있어서, 상기 제1집속 전극(25)이 상기 제2집속 전극(26)에 인접하고 있는 전면 부전극(28)과, 배면 부전극(27) 및, 상기 전면 부전극 (28)의 부근에 배치되어 4중극 렌즈를 형성하는 비점 수차 소자(GAST)를 포함하고, 동작동안에 상기 비점 수차 소자는 정전압(Vfoc)인가수단에 접속되는 반면 적어도 상기 전면 부전극이 가변 제어 전압(Vfoc+Vc)인가수단에 접속되어, 동작시, 상기 전면 부전극(28)과 상기 제2집속 전극(26)의 사이에 형성된 주 집속 렌즈 펠드와 상기 비점 수차 소자(GAST)간의 결합된 집속 작용에 의해, 상기 제어전압의 변화가 전자빔의 집속에 제1방향으로는 사실상 영향을 미치지 않도록 하는 반면 상기 제1방향과 수직인 제2방향으로는 전자빙의 집속에 영향을 미치도록 하는 것을 특징으로 하는 칼라 표시관.
- 제1항에 있어서, 상기 가변 제어 전압이 일정한 값으로 설정되는 것을 특징으로 하는 칼라 표시관.
- 제1항에 있어서, 상기 제어 전압이 스크린을 가로지르는 빔의 편향과 함께 동적으로 변하는 것을 특징으로 하는 칼라 표시관.
- 제3항에 있어서, 상기 동적으로 변하는 전압이 라인 편향 전압에 동기적인 포물선형 성분을 갖는 것을 특징으로 하는 칼라 표시관.
- 제3항에 있어서, 상기 동적으로 변하는 전압이 라인 편향 필드 및 편향에 각각 동기적인 포물선형 성분들의 조합을 포함하는 것을 특징으로 하는 칼라 표시관.
- 제1항에 있어서, 동작동안에 상기 두 개의 부전극이 제어 전압 인가수단에 접속되는 것을 특징으로 하는 칼라 표시관.
- 제1항에 있어서, 동작동안에 단지 상기 전면 부전극만이 제어 전압 인가수단에 접속되는 것을 특징으로 하는 칼라 표시관.
- 제7항에 있어서, 동작동안에 상기 배면 부전곡 및 상기 비점 수차 소자가 동일한 정전압 인가 수단에 접속되는 것을 특징으로 하는 칼라표시관.
- 제8항에 있어서, 상기 비점 수차 소자는 상기 배면 부전극에 부착되는 것을 특징으로 하는 칼라 표시관.
