Abstract

본 발명은 음극선관용 새도우 마스크에 관한 것으로 특히 돗트형 음극선관리 여유도를 증가시키기 위하여 전자빔의 미스랜딩 방향에 대하여 전자빔폭이 작게 형성되도록 새도우 마스크 슬록 형상을 만들어 색순도 여유도를 증가시키도록 한 것으로써, 돗트형 새도우 마스크를 가진 음극선관에 있어서, 새도우 마스크를 통과한 저자빔의 형상을 편향요크의 전후 이동시 전자빔의 미스랜딩 방향으로의 슬롯폭이 상대적으로 작게 구성하여 색순도의 여유도를 증가시킬 수 있도록 한 것이다.The present invention relates to a shadow mask for cathode ray tube, in particular to increase the color purity margin by making the shadow mask slop shape so that the electron beam width is formed small with respect to the mislanding direction of the electron beam in order to increase the dot type cathode ray management margin , In the cathode ray tube with dot-type shadow mask, the shape of the low-beam beam passing through the shadow mask can be configured to have a relatively small slot width in the direction of mis-landing of the electron beam when the deflection yoke is moved back and forth to increase the margin of color purity. It would be.
