Claims (2)
- 칼라 음극선관용 섀도우마스크에 무수히 많은 슬롯을 형성하도록 된 것에 있어서, 슬롯의 Y축 유효면 가장자리의 반경(Ry)을 기준으로 하여 X축 유효면 가장자리의 반경(Rx)과 D축 유효면 가장자리의 반경(Rd)까지의 테이퍼 아웃(To)을 그래이딩하여서 된 음극선관용 섀도우마스크.
- 제1항에 있어서, Ry와 Rx구간에서는 To(Ry) ≤ To ≤ 1.15 * To(Rx)이고, Rx와 Rd구간에서는 To(Rx) ≤ To ≤ 1.30 * To(Rd)로 하여 테이퍼 아웃 폭이 섀도우마스크반경에 대해 직선적으로 증가되지 않도록 함을 특징으로 하는 음극선관용 섀도우마스크.
