Abstract

본 발명은 음극선관을 개시한다.The present invention discloses a cathode ray tube.

본 발명은 내면에 형광막이 형성된 패널과, 상기 패널의 내부에 설치된 새도우마스크 프레임조립체와, 상기 패널과 봉착되는 것으로 그 네크부에 전자총이 봉입된 펀넬을 구비하여 된 음극선관에 관한 것으로서, 상기 패널이 그 스크린면의 각 부위에 따라 투과율이 서로 다르게 된 것에 특징이 있으며, 이는 음극선관의 전 화면에서 균일한 휘도를 얻을수 있는 이점이 있다.The present invention relates to a cathode ray tube comprising a panel having a fluorescent film formed on an inner surface thereof, a shadow mask frame assembly installed inside the panel, and a funnel having an electron gun encapsulated therein, the panel being encapsulated with the panel. This is characterized in that the transmittance is different according to each part of the screen surface, which has the advantage of obtaining a uniform brightness across the entire screen of the cathode ray tube.
