Description

음극 선관
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 1실시예의 새도우마스크형 컬러 브라운관의 부분축단면도.
제2도는 제1도의 선 2-2에서 취한 면판패널의 정면도.
제3도, 제4도 및 제5도는 각각 제2도의 선 3-3, 4-4,5-5를 따라 취한패널의 횡단면도.

Claims (4)

  1. 각각 단축 및 장축을 따른 곡률을 갖는 외부표면을 가진 시각면 스크린을 포함하는 음극선관에 있어서, 적어도 면판 패널(18)의 중심부에서 단축(Y)을 따른 곡률이 장축(X)을 따른 곡률보다, 크고, 교차 부분에서 단축과 평행하는 상기 면판의 외부표면은 단축과 거리가 벌어짐에 따라 상기 교차부의 곡률을 감소시키면서 구부러지는 것을 특징으로 하는 음극선관.
  2. 제1항에 있어서, 상기 외부표면이 상기 면판의 주변가까이에서 사각형의 등고선을 이루고 상기 관(10)의 중앙 수직축(Z)에 직각을 이루는 평면으로 형성된다는 것을 특징으로 하는 음극선관.
  3. 제1항에 있어서, 상기 면판의 가장자리 가까이에서 장축을 따른 곡률이 상기 면판의 중앙부분에서 장축을 따른 곡률보다 크다는 것을 특징으로 하는 음극선관.
  4. 제1항에 있어서, 면판의 가장자리 가까이에서 장축을 따른 곡률이 단축을 따른 곡률보다 크다는 것을 특징으로 하는 음극선관.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
