Abstract

본 발명은 칼라음극선관의 형광막 구성에 관한 것으로 특히 형광체액이 판넬내면에 두껍게 도포될수 있도록 하여 크랙의 발생을 감소시키고 크랙이 있는 단층구조의 흑연막의 형광막보다 휘도를 향상시키며, 형광막의 두께를 균일하게 하여 형광면의 백색균일성 불량을 방지할 수 있는것으로서, 흑연막의 두께를 증가시킴으로 형광체액이 두껍게 도포될 수 있도록 흑연막을 다단으로 구성한 것이다.The present invention relates to the composition of the fluorescent film of the color cathode ray tube, and in particular, the phosphor solution can be thickly applied to the inner surface of the panel to reduce the occurrence of cracks and improve the luminance than the fluorescent film of the graphite film having a single layer structure with cracks, the thickness of the fluorescent film By uniformly preventing the white uniformity defect of the fluorescent surface, by increasing the thickness of the graphite film is composed of a multi-stage graphite film so that the phosphor liquid can be thickly applied.
