Abstract

본 발명은 칼라음극선관의 판넬구조에 관한 것으로 특히 외면이 평면화된 판넬유리의 내면을 중심부와 주변부의 두께를 다르게 하여 미스컨버젼스 불량을 제거하도록 한 것으로서, 판넬유리의 내면을 구면화시킨 것이다.The present invention relates to a panel structure of a color cathode ray tube, and in particular, an inner surface of a panel glass whose outer surface is flattened so as to remove misconvergence defects by varying a thickness of a central portion and a peripheral portion, and spheroidized an inner surface of the panel glass.
