Abstract

본 발명은 신규한 구성의 칼라 브라운관과 이를 제조하기에 적합한 제조방법을 개시한다.The present invention discloses a color CRT tube of novel construction and a manufacturing method suitable for producing the same.

종래의 칼라 브라운관은 유효면의 외곽선이 직선이 아니어서 여러 가지 문제가 있었으나, 평면 사각 브라운관은 별도 설계를 해야하므로 그 제조원가가 큰 문제가 있었다.Conventional color CRTs have various problems because the effective surface is not a straight line, but the flat rectangular CRTs have to be designed separately, so there is a big problem in manufacturing cost.

본 발명에서는 블랙 매트릭스로 형광면의 일부를 차폐함으로써 일반적인 칼라 브라운관의 구성부품과 제조공정을 그대로 이용하면서도 직사각형의 유효면을 제공할수 있도록 하였다.In the present invention, by shielding a part of the fluorescent surface with a black matrix, it is possible to provide a rectangular effective surface while using the components and manufacturing process of the general color CRT as it is.

Claims (8)

색선별 수단인 섀도우 마스크를 노광마스크로 하여 블랙 매트릭스와 각 형광체를 패널의 내면에 순차적으로 사진식각함으로써 구성한 형광면을 가지는 칼라 브라운관에 있어서, 상기 패널의 유효면의 면적이 상기 섀도우 마스크의 유공부의 패널 투영부 면적보다 작은 것을 특징으로 하는 칼라 브라운관.In a color CRT having a fluorescent surface formed by sequentially etching a black matrix and phosphors on the inner surface of the panel using a shadow mask as a color masking means as an exposure mask, the area of the effective surface of the panel is defined by the perforations of the shadow mask. A color CRT tube smaller than the panel projecting area. 제1항에 있어서, 상기 유효면의 코너부의 각 꼭지점이 상기 패널 투영부의 코너부의 각 꼭지점과 일치하는 것을 특징으로 하는 칼라 브라운관.The color CRT tube according to claim 1, wherein each vertex of the corner portion of the effective surface coincides with each vertex of the corner portion of the panel projection portion. 제1항에 있어서, 상기 유효면이 직사각형의 형태를 가지는 것을 특징으로 하는 칼라 브라운관.The color CRT tube according to claim 1, wherein the effective surface has a rectangular shape. 제1항에 있어서, 상기 형광체가 상기 패널 투영부에 형성되고, 상기 블랙 매트릭스가 상기 패널 투영부의 일부를 차폐하여 소정형태의 유효면을 형성하는 것을 특징으로 하는 칼라 브라운관.The color CRT tube according to claim 1, wherein the phosphor is formed on the panel projection, and the black matrix shields a part of the panel projection to form an effective surface of a predetermined shape. 색선별수단인 섀도우 마스크를 노광마스크로 하여 블랙 매트릭스와 각 형광체를 패널의 내면에 순차적으로 사진식각하여 형광면을 제조하는 칼라브라운관의 제조방법에 있어서, 상기 블랙 매트릭스의 노광시에는 그 노광범위를 제한하는 보조마스크를 장착하여 노광하고, 상기 각 형광체의 노광시에는 상기 보조마스크를 제거하여 노광하는 것을 특징으로 하는 칼라 브라운관의 제조방법.In the manufacturing method of a color brown tube in which a black matrix and phosphors are sequentially etched on the inner surface of a panel by using a shadow mask as a color selection means as an exposure mask, the exposure range is limited when the black matrix is exposed. And an auxiliary mask to be exposed, and when the respective phosphors are exposed, the auxiliary mask is removed and exposed. 제5항에 있어서, 상기 보조마스크가, 상기 섀도우 마스크의 전면측 또는 후측에 장착되는 림형태로 구성되는 것을 특징으로 하는 칼라 브라운관의 제조방법.The method of claim 5, wherein the auxiliary mask is configured in the form of a rim mounted on the front side or the rear side of the shadow mask. 제5항에 있어서, 상기 보조마스크가, 상기 노광범위를 제한하는 부분에 불투명층을 가지는 투명판인 것을 특징으로 하는 칼라 브라운관의 제조방법.The method of manufacturing a color CRT tube according to claim 5, wherein the auxiliary mask is a transparent plate having an opaque layer at a portion limiting the exposure range. 제5항에 있어서, 상기 보조마스크가, 상기 섀도우 마스크에 접착 및 분리가능한 불투명 테이프로 구성되는 것을 특징으로 하는 칼라 브라운관의 제조방법.The method of claim 5, wherein the auxiliary mask is made of an opaque tape that can be attached to and detached from the shadow mask. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
