Abstract

본 발명은 신규한 구성의 칼라 브라운관과 이에 사용될수 있는 프레임 및 홀더 스프링을 개시한다.The present invention discloses a novel CRT tube and a frame and holder spring that can be used therein.

종래의 곡면형 칼라 브라운관은 섀도우 마스크의 성형이 필요하여 그 제조 및 취급이 곤란하고, 평면형 칼라브라운관의 컨버전스 특성등이 열악한 문제가 있었다.Conventional curved color CRTs require shaping of shadow masks, making them difficult to manufacture and handle, and have poor convergence characteristics such as flat color CRTs.

본 발명은 곡면형 패널에 평면형 마스크를 결합하여 제작이 간편하고 화질이 우수한 칼라 브라운관을 구현하였으며, 이 칼라 브라운관에 특히 적합하며 다른 방식의 브라운관에도 사용될수 있는 프레임과 홀더 스프링을 함께 개시하고 있다.The present invention implements a color CRT with a flat panel mask coupled to a curved panel, which is easy to manufacture and has excellent image quality, and discloses a frame and a holder spring which are particularly suitable for this CRT and can be used for other CRT tubes.

Claims

A color CRT comprising a panel having a fluorescent surface and a shadow mask for selectively applying an electron beam to the fluorescent surface, wherein the CRT comprises a curved panel and a flat shadow mask.

The color CRT according to claim 1, wherein the color-selective holes formed in the shadow mask become larger from the center of the shadow mask toward the periphery thereof.

2. The color CRT of claim 1, wherein the shadow mask is a tensile mask to which a predetermined tensile force is applied.

4. The color CRT tube according to claim 3, wherein the method of applying a tensile force to the shadow mask is a method of bonding the shadow mask to the frame while thermally expanding the shadow mask.

A shadow mask frame of a color cathode ray tube supporting a shadow mask, wherein a cross section has at least two wings.

The color CRT tube according to claim 5, wherein the cross section has any one of "V", "U" and "W" characters.

A holder spring of a color CRT tube attached to an outer circumference of a frame and supporting the panel, the tab joined to the frame, a stock bent and extended in an opposite direction from the tab, and provided at a tip of the stock, wherein the panel is provided. Color CRT tube characterized by having a holder coupled to the stud pin of the.

8. The color CRT tube of claim 7, wherein a lever for convenience of coupling and detachment of the operator is extended to the tip of the holder.

8. The collar tube of claim 7, wherein the stock of the holder spring extends in the tube axis direction of the collar tube.
