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.

Claims (3)

패널의 내면에 도포된 적, 녹, 청색의 형광체층이 소정의 패턴으로 형성되어 이루어진 형광막을 형성하기 위한 칼라 음극선관의 노광방법에 있어서, 광원으로 조사되는 광을 쐐기 형상의 보조렌즈의 가장자리를 통과시켜 패널의 내면에 도포된 적색 형광체층 소정의 패턴으로 노광하는 단계와, 상기 광을 쐐기 형상의 보조렌즈의가장자리를 통과시켜 패널의 내면에 도포된 청색 형광체층 소정의 패턴으로 노광하는 단계와, 상기 쐐기 형상의 보조렌즈를 패널측으로 소정높이 이송시키고 상기 광을 보조렌즈의 중앙부를 통과시켜 패널의 내면에 도포된 녹색 형광체층을 소정의 패턴으로 노광하는 단계를 포함하여 된 것을 특징으로 하는 칼라 음극선관의 노광방법.In the exposure method of a color cathode ray tube for forming a fluorescent film in which red, green, and blue phosphor layers applied to an inner surface of a panel are formed in a predetermined pattern, light irradiated with a light source is formed at an edge of a wedge-shaped auxiliary lens. Exposing the light to a predetermined pattern of red phosphor layer applied to the inner surface of the panel, and exposing the light to a predetermined pattern of blue phosphor layer applied to the inner surface of the panel by passing the light through the edge of the wedge-shaped auxiliary lens; And transferring the wedge-shaped auxiliary lens to a panel at a predetermined height and exposing the green phosphor layer coated on the inner surface of the panel in a predetermined pattern by passing the light through a central portion of the auxiliary lens. Exposure method of cathode ray tube. 제1항에 있어서, 상기 적색 형광체층과 청색 형광체층을 노광하는 단계에 있어, 적색 형광체층의 노광후 상기 쐐기 형상의 보조렌즈를 그 중앙부분 중심으로 회진시켜 적색형광체층의 패턴시 형성시 광이 통과한 부위와 동일한 부위로 청색 형광체층을 형성하기 위한 광이 입사되도록 된 것을 특징으로 하는 칼라 음극선관의 노광방법.The method of claim 1, wherein in the exposing of the red phosphor layer and the blue phosphor layer, the wedge-shaped auxiliary lens is rotated around the center of the red phosphor layer after exposure of the red phosphor layer to form a red phosphor layer during pattern formation. An exposure method of a color cathode ray tube, wherein light for forming a blue phosphor layer is incident on a portion identical to the portion passing therethrough. 제1항에 있어서, 상기 녹색 형광체층의 노광시 상기 보조렌즈의 이송거리가 적색, 청색 형광체층의 노광시 광이 통과한 부위의 보조렌즈두께와 렌즈 중앙부의 두께차이 만큼 이송된 것을 특징으로 하는 칼라 음극선관의 노광방법.The method of claim 1, wherein the transfer distance of the auxiliary lens when the green phosphor layer is exposed is transferred by a difference between the thickness of the auxiliary lens and the thickness of the center portion of the lens where the light passes when the blue phosphor layer is exposed. Exposure method of colored cathode ray tube. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
