Abstract

본 발명은 칼라음극선관을 개시한다.The present invention discloses a color cathode ray tube.

본 발명은 다수의 전자빔통과공이 형성된 섀도우마스크와, 상기 섀도우마스크의 스커트부와 용접되어 상기 섀도우마스크를 지지하는 프레임을 구비하여 된 칼라음극선관에 있어서, 섀도우마스크의 장변부와 단변부 길이의 1/2을 각각 ℓℓ′이라 하고 상기 각 장, 단변부 길이의 중심으로부터 임의의 점까지의 길이를 각각 Lℓ,Sℓ이라 할때 식,를 만족하는 범위내에 상기 섀도우마스크와 프레임을 용접하는 용접점이 두개이상 존재하는 것에 특징이 있으며, 이는 섀도우마스크의 도밍량을 대폭 줄일 수 있는 이점을 가진다.The present invention relates to a color cathode ray tube having a shadow mask having a plurality of electron beam through holes formed therein, and a frame welded to the skirt portion of the shadow mask to support the shadow mask, wherein the length of the long side and the short side of the shadow mask is 1. Where / 2 is respectively Lℓ 'and the length from the center of the length of each of the long and short sides to an arbitrary point is Lℓ and Sℓ, respectively. , It is characterized in that there are two or more welding points for welding the shadow mask and the frame within a range satisfying this, which has the advantage that can greatly reduce the dominant amount of the shadow mask.
