Abstract

본 발명은 칼라 브라운관의 개선된 섀도우마스크를 개시한다. 섀도우마스크의 유공부는 강도가 거의 없어 스크어트의 변형이 전파되어 쉽게 변형됨으로써 화상의 품위와 안정성을 저하시키는 문제가 있었다. 본 발명에서는 적어도 무공부에 프리트의 도포 및 소성등으로 보강층을 형성하여 변형의 전파를 차단하고 그 발생을 억지하도록 하였다.The present invention discloses an improved shadow mask of a color CRT. Since the perforations of the shadow mask have little strength, deformation of the scaffold is propagated and easily deformed, thereby degrading image quality and stability. In the present invention, a reinforcing layer is formed at least in the unperforated portion by applying and firing the frit to block propagation of deformation and suppress the occurrence thereof.
