Abstract

본 발명은 칼라 브라운관의 섀도우 마스크와 프레임 조립체에 관한 것이다.The present invention relates to a shadow mask and frame assembly of a color CRT.

일반적으로 전자총에서 발사된 전자빔은 색분리 전극인 섀도우 마스크를 통과하여 적, 청, 녹의 3색이 도포된 형광면을 발광시키는데, 이 섀도우 마스크는 패널과 퍼넬로 이루어진 브라운관 내에서 프레임에 의해 지지 고정된다.In general, an electron beam emitted from an electron gun passes through a shadow mask, which is a color separation electrode, to emit a fluorescent surface coated with three colors of red, blue, and green. The shadow mask is supported by a frame in a CRT composed of a panel and a funnel. .

통상적인 섀도우 마스크와 프레임의 조립방식은 섀도우 마스크를 프레임의 내측 또는 외측에 결합하고 이결합부를 스포트 용접으로 일정한 가압력을 유지하면서 고정하게 된다.Conventional shadow mask and frame assembly is a method of assembling the shadow mask to the inside or outside of the frame and to fix the coupling portion while maintaining a constant pressing force by spot welding.

이때의 가압력에 의해 섀도우 마스크와 프레임의 변형이 발생하여 색순도의 저하를 초래하는 것이다.In this case, deformation of the shadow mask and the frame occurs due to the pressing force, which causes color purity to decrease.

본 발명은 섀도우 마스크(3)와 프레임(4)의 하단 및 상단둘레에 직각의 플랜지(3b)(4a)를 각각 형성하고 이들 플랜지를 상호간 면접하여 스포트 용접시키므로써 마스크와 프레임의 변형 방지에 따른 색순도의 향상과 마스크의 폐쇄문제를 해결할 수 있는 발명이다.According to the present invention, flanges 3b and 4a at right angles are formed at the lower and upper circumferences of the shadow mask 3 and the frame 4, and the flanges are interviewed with each other for spot welding to prevent deformation of the mask and the frame. It is an invention that can solve the problem of improving color purity and mask closure.
