Abstract
본 발명은 칼라 음극선관의 개선된 섀도우마스크를 개시한다.The present invention discloses an improved shadow mask of a color cathode ray tube.
종래에는 고강도 재질의 섀도우마스크에 있어서 스커어트의 스프링백이 심해 음극선관의 화질을 열화시키는 문제가 있었다. 본 발명에서는 페이스와 스커어트의 경계부에 교차하는 복수의 보강리브를 구비하여 섀도우마스크의 강도가 증대되고 스커어트의 스프링배이 최대한 억제되도록 함으로써 음극선관의 화질이 향상되도록 하였다.Conventionally, in the shadow mask made of a high-strength material, the spring back of the skirt is severe and there is a problem of deteriorating the image quality of the cathode ray tube. In the present invention, a plurality of reinforcing ribs intersecting the boundary between the face and the skirt is provided so that the strength of the shadow mask is increased and the spring times of the skirt are suppressed to the maximum, thereby improving the image quality of the cathode ray tube.
