Abstract

본 발명은 칼라 음극선관의 프레임 구조에 관한 것으로, 프레임의 섀도우마스크 접촉면 후방에 상기 프레임보다 열변형율이 높은 바아메탈부재를 접착고정하여 섀도우마스크이 열을 전달받아 드레임이 팽창될때 상기 프레임에 접착고정된 바아메탈부재가 지지스프링의 수축과 더불어 변형되도록 함에 따라 초기 도밍보상을 신속히 이루어 색순도가 향상된 깨끗한 화면이 빠른 시간내에 재현되도록 한 것이다.The present invention relates to a frame structure of a color cathode ray tube, wherein a bar metal member having a higher thermal strain is fixed to a rear surface of a shadow mask contact surface of the frame to be bonded to the frame when the shadow mask receives heat and expands the frame. As the bar metal member is deformed along with the contraction of the support spring, initial doming compensation is quickly performed, so that a clear screen with improved color purity is reproduced in a short time.

이를위해 본 발명은 코너부(11a)와 섀도우마스크 고정부(11b) 그리고 스커트부(11c)로 일체화된 프레임(11)에 있어서, 상기 섀도우마스크 고정부(11b)의 후방으로 섀도우마스크 고정부와 열변형율이 서로 다른 재질로 된 바이메탈부재(12)를 부착하여 구성한 것이다.To this end, the present invention provides a frame 11 integrated with a corner portion 11a, a shadow mask fixing portion 11b, and a skirt portion 11c, and a shadow mask fixing portion to the rear of the shadow mask fixing portion 11b. It is constructed by attaching the bimetal member 12 made of a material having different thermal strains.
