Abstract
Description
Claims (4)
- 음극발광라인 스크린(22)에 인접하여 장착된 새도우마스크를 구비한 것으로서, 상기 새도우마스크가 열로 배치된 복수의 슬릿형 개구를 가지고 두 개의 대향하는 장측가 두 개의 대향하는 단측을 가진 실질적으로 다소 구형인 주변부를 가지며, 상기 마스크의 주축(X-X)은 마스크의 중앙을 통과하여 단측을 따라 중앙에서 연장되는 축이고 상기 마스크의 소축(X-Y)은 마스크의 중앙을 통과하여 단측을 따라 중앙에서 연장되는 축이며, 상기 개구 열은 일반적으로 소축의 방향으로 연장되고 주축의 방향에서 서로 이격되도록한 칼라수상관(10)에 있어서,상기 마스크의 소축 근처에서의 개구 열 대 열 간격(AH)이 상기 마스크의 장축에서 상기 마스크의 주축근처에서 보다 작은 것을 특징으로 하는 칼라 수상관.
- 제 1항에 있어서,개구 열 대 열 간격(AH)이 주축(X-X)근처에서 보다 상기 마스크(24)의 모서리 근처에서 더 큰 것을 특징으로하는 칼라수상관.
- 제 1항에 있어서,주축(X-X)에 평행하지만 주축으로부터 떨어져있는 횡단면을 따르는 개구 열 대 열 간격(AH)의 대략 방정식 A=a+bx2+cx4에 따라 변동되는 데, 여기서, A는 개구 열 대 열 간격이고 a,b,c는 주축으로부터의 거리의 제곱의 다른 함수이며 x는 소축(Y-Y)로부터의 거리인 것을 특징으로 하는 칼라 수상관.
- 제 1항 또는 3항에 있어서,주축(X-X)을 따른 개구 열 대 열 간격(AH)이 대략소축(Y-Y)로 부터의 거리의 4승의 함수로서 증가하는 것을 특징으로 하는 칼라 수상관.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
