Abstract
본 발명은 칼라 음극선관의 형광막을 제조함에 있어 적색 형광체 형성시 패턴 바깥쪽에 패턴 마스크를 설치하고 광원으로부터 패널 상으로 자외선을 조사하여 노광한 다음, 현상시키는 것을 특징으로 한다. 이러한 외면 노광법에 따르면 노광 효율이 향상될 뿐 아니라 공정 수행상의 잇점이 있으며, 휘도 및 선명도가 현저하게 향상된 형광막을 얻을 수 있다.The present invention is characterized in that in manufacturing a fluorescent film of a color cathode ray tube, when a red phosphor is formed, a pattern mask is provided on the outside of the pattern, the ultraviolet light is exposed to the panel from the light source, and then developed. According to the external surface exposure method, not only the exposure efficiency is improved, but also there are advantages in performing the process, and a fluorescent film with remarkably improved brightness and clarity can be obtained.
