Abstract

음극선관의 스크린은 광도전층에 이중으로 블랙 스트라이프 및 투광상막을 형성하도록 하여 투고아성 막이 볼록렌즈의 역할을 하도록 히므로서 스크린의 콘트라스트 향상 및 휘도를 향상하도록 한 것이다.The screen of the cathode ray tube is to form a black stripe and a transparent film on the photoconductive layer so that the transparent sub-film acts as a convex lens, thereby improving the contrast and brightness of the screen.

소정의 배열구조로 판넬 배면에 형성된 1차 빛흡수물질과, 볼록렌즈역할을 하도록 그 빛흡수물질 배역구조 사이가 볼록하게 그 제1차 빛흡수물질 배열구조 사이에 형성되는 투광집속막과, 그 1차 빛흡수물질위에 그 1차 빛흡수물질의 배열구조와 동일하게 형성되는 2차 빛흡수물질과, 그 2차 빛흡수물질 사이에 형성되는 형광체막을 지니는 스크린을 구비하는 것윽 특징으로 하는 음극선관을 제공한다. 이에 따라, 상기 투광성막이 볼록렌즈의 역할을 하게 되어 새도우 마스크의 개구부를 통해 주사되는 전자빔을 최대한 형광막에 입사시키고 이를 집속시키게 되므로 스크린의 콘트라스트 향상 및 스크린의 휘도를 향상시키는 잇점이 있다.A light condensing film formed between the primary light absorbing material formed on the rear surface of the panel in a predetermined arrangement structure and the light absorbing material transport structure convex so as to act as a convex lens; A cathode ray tube comprising a secondary light absorbing material formed on the primary light absorbing material in the same arrangement as the primary light absorbing material, and a screen having a phosphor film formed between the secondary light absorbing materials; To provide. Accordingly, the light-transmitting film serves as a convex lens, thereby injecting the electron beam scanned through the opening of the shadow mask to the fluorescent film as much as possible and concentrating it, thereby improving the contrast of the screen and the brightness of the screen.
