Abstract
본 발명은 칼라 음극선관의 노광방법을 개시한다.The present invention discloses a method for exposing a colored cathode ray tube.
본 발명은 패널의 내면에 도포된 적, 녹, 청색의 형광체층이 소정의 패턴으로 형성되어 이루어진 형광막을 형성하기 위한 칼라 음극선관의 노광방법에 관한 것으로, 광원으로 조사되는 광을 쐐기 형상의 보조렌즈를 가장자리를 통과시켜 패널의 내면에 도포된 적색 형광체층 소정의 패턴으로 노광하는 단계와, 상기 광을 쐐기 형상의 보조렌즈의 가장자리를 통과시켜 패널의 내면에 도포된 청색 형광체층 소정의 패턴으로 노광하는 단계와, 상기 쇄기 형상의 보조롄즈를 패널측으로 소정높이 이송시키고 상기 광을 보조렌즈의 중앙부를 통과시켜 패널의 내면에 도포된 녹색 형광체층을 소정의 패턴으로 노광하는 단계를 포함하여 된 것에 특징이 있으며, 이는 각 형광체에 정확하게 전자빔이 랜딩되도륵 하여 화상의 해상도를 향상시킬 수 있는 이점을 가진다.The present invention relates to a method for exposing a color cathode ray tube for forming a phosphor film formed by forming a red, green, and blue phosphor layer coated on an inner surface of a panel in a predetermined pattern. Exposing the lens to a predetermined pattern of red phosphor layers applied to the inner surface of the panel through the edges; and passing the light through the edges of the wedge-shaped auxiliary lens to a predetermined pattern of blue phosphor layers applied to the inner surface of the panel. And exposing the green phosphor layer coated on the inner surface of the panel in a predetermined pattern by transferring the wedge-shaped auxiliary liances to a panel at a predetermined height and passing the light through a central portion of the auxiliary lens. This has the advantage that the electron beam can be accurately landed on each phosphor to improve the resolution of the image. It is.
