Abstract

본 발명은 평면 칼라 음극선관의 섀도우마스크 진동 감쇠장치에 관한 것으로서, 기기에 장착된 상태에서 상기 기기가 동작할때 외부의 충격이나 스피커의 음압등에 따른 진동요인이 섀도우마스크에 전달되더라도 댐핑역할에 의한 여진진동 시간이 감소되도록 섀도우마스크 진동 감쇠장치를 제공하여 음극선관의 특성이 크게 떨어지지 않도록 함에 따라 화면상태가 항상 양호하도록 한 것이다.The present invention relates to a shadow mask vibration damping device for a flat color cathode ray tube, and more particularly, to a shadow mask vibration damping device for a flat color cathode ray tube, The shadow mask vibration damping device is provided so that the excitation vibration time is reduced so that the characteristics of the cathode ray tube are not greatly deteriorated so that the picture quality is always good.

이를 위해 본 발명은 프레임에 고정되어 있는 새도우마스크 비유효면에 코너부분을 제어하고 장변 및 단변으로 각각 복수개의 구멍으로 구멍부를 형성하여 상기 비유효면의 면적이 구멍부 만큼 줄어들도록 한 것이다.To this end, the present invention controls the corner portion on the ineffective surface of the shadow mask fixed to the frame and forms a hole with a plurality of holes each having a long side and a short side so that the area of the ineffective surface is reduced by the hole portion.
