Description

투사형 음극선관
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 1실시예의 광학다중간섭막을 구비한 투사형 음극선관의 앞면패널 및 형광면을 도식적으로 도시한 단면도,
제2도는 투사형 음극선관의 광출력의 경시적인 저하를 도시한 특성도.

Claims (3)

  1. 형광면을 구성하는 앞면패널(1)과 형광체층(3) 사이에 고굴절막과 저굴절막을 교대로 형성해서 이루어지는 광학 다중간섭막(2)를 구비한 투사형 음극선관에 있어서, 상기 광학다중간섭막(2)와 앞면패널(1) 사이에 광학박막층으로써 작용하지 않는 투명무기재료막(5)를 개재시킨 투사형 음극선관.
  2. 특허청구의 범위 제1항에 있어서, 상기 투명무기재료막(5)의 재료로써 이산화규소 또는 산화알루미늄을 사용하는 투사형 음극선관.
  3. 특허청구의 범위 제2항에 있어서, 상기 이산화규소 또는 산화알루미늄의 막두께가 각각 500Å 이상 또는 5000Å 이상인 투사형 음극선관.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
