Description

음극선관
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 1실시예의 새도우마스크형 컬러 브라운관의 부분측단면도.
제2도는 제1도의 선2-2에서 취한 면판패널의 정면도.
제3도, 제4도 및 제5도는 각각 제2도의 선 3-3, 4-4, 5-5을 따라 취한 패널의 횡단면도.

Claims (6)

  1. 장축 및 단축을 따른 곡률을 갖는 새도우 마스크가 장치된 음극선관에 있어서, 상기 마스크(24, 32, 40)의 가장자리에서의 장축을 따른 곡률이 상기 마스크의 중앙부분에서의 장축을 따른 곡률보다 크다는 것을 특징으로 하는 음극선관.
  2. 상기 제1항에 있어서, 상기 새도우 마스크(24, 32)내에서 장축(X)을 따른 곡률과 단축(Y)을 따른 곡률은 서로 다르다는 것을 특징으로 하는 음극선관.
  3. 제항에 있어서, 장축(X)과 평행한 새도우 마스크(40)의 가장자리를 따른 곡률은 상기 마스크의 가장자리에서 장축을 따른 곡률보다 상기 마스크의 가장자리에서 작다는 것을 특징으로 하는 음극선관.
  4. 제1항에 있어서, 상기 새도우 마스크(24, 32)의 중심에서 가장자리까지의 등고선 은 제2도함수에서 적어도 한번의 부호변환을 갖는다는 것을 특징으로 하는 음극선관.
  5. 제1항에 있어서, 단축(Y)을 따른 등고선(36)의 제2도함수는 단축에 평행한 마스크(40) 가장자리에서의 등고선(38)의 제2도함수에 대해 반대부호를 갖는다는 것을 특징으로 하는 음극선관.
  6. 제1항에 있어서, 상기 마스크(24, 32)의 가장자리에서 단축(Y)에 평행한 평면의 곡률은 장축(X) 가까이에서 보다 크다는 것을 특징으로 하는 음극선관.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
