Abstract

본 발명은 칼라 음극선관용 섀도우마스크 프레임 조립체를 개시한다.The present invention discloses a shadowmask frame assembly for a color cathode ray tube.

본 발명은 다수의 전자빔 통과공이 형성되 유공부와, 이 유공부의 가장자리로부터 수직하방으로 연장되는 스커트부를 구비하여된 섀도우마스크와 이 섀도우마스크의 스커트부와 결합되는 지지부가 마련된 프레임과, 상기 스커트부와 지지부 사이에 개재되어 지지부에 스커트부를 지지하는 지지수단을 구비하여 구성된 것에 그 특징이 있으며, 이는 초기에 섀도우마스크 도밍량을 보상하여 초기 화면의 안정화를 꽤할 수 있는 잇점을 가진다.The present invention provides a frame having a plurality of electron beam through holes formed therein, a frame provided with a shadow mask including a skirt portion extending vertically downward from an edge of the hole portion, and a support portion coupled to the skirt portion of the shadow mask, wherein the skirt portion is provided. It is characterized in that it is provided between the support portion and the support means for supporting the skirt portion in the support portion, which has the advantage that the initial screen can be stabilized by compensating the shadow mask dope amount initially.
