Abstract
Description
Claims (5)
- 블랙 매트릭스 형성공정 및 형광막 노광시 섀도우마스크를 제품에 적용할 때 가열되는 온도분포와 동일한 온도조건이 되게 섀도우마스크의 중심구역에서 외곽구역으로 갈수록 낮은 온도로 섀도우마스크를 가열시킨 상태에서 블랙 매트릭스 및 형광막을 형성하도록 된 칼라 음극선관의 형광면 형성방법.
- 섀도우마스크가 고정된 전면판넬을 지지하는 톱 플레이트의 하방에 필터, 보정렌즈, 광원을 차례로 설치하여 노광공정을 수행하도록 된 것에 있어서, 필터와 톱 플레이트 사이에 섀도우마스크의 전표면의 온도를 서로 다른 온도로 가열시키는 가열부를 구비하여서 된 칼라 음극선관의 형광면 형성장치.
- 제 2 항에 있어서, 가열부는 열선으로 하여 중심부는 간격이 좁고 외곽으로 갈수록 넓은 달팽이관 형태로 감아서 된 칼라 음극선관의 형광면 형성장치.
- 제 3 항에 있어서, 열선이 고 용융 열선으로 된 칼라 음극선관의 형광면 형성장치.
- 제 3 항 또는 제 4 항에 있어서, 열선의 중심부와 주변부 저항값을 달리하여 상기 열선의 저항값으로 섀도우마스크의 가열온도를 조정하도록 된 칼라 음극선관의 형광면 형성장치.
