Abstract
본 발명은 음극선관의 도우밍 보상장치에 관한 것이다. 종래에는 도우밍의 보상을 위하여 탄성부재(12)에 열전달이 이루어져야 동작을 함으로써 보상시간이 오래 걸리는 단점이 있었으며, 또한 원재료가 다른 금속을 용접하여 사용함으로써 온도 전달에 따른 열변위량의 편차가 많아 색어긋남을 효과적으로 보상하지 못하는 등의 여러 문제점이 있었다. 본 발명은 새도우마스크(6)의 열팽창에 의한 도우밍현상을 보상하는 탄성부재(20)를 형상기억금속으로 형성함으로써 새도우마스크의 열팽창에 의한 색어긋남으로 발생되는 색순도저하를 보다 신속하고 정확하게 보상하도록 한 것이다.The present invention relates to a device for compensating for a cathode ray tube. Conventionally, there is a disadvantage in that the compensation time is long by operating heat transfer to the elastic member 12 to compensate for the domming. Also, since the raw materials are welded with different metals, there are many variations in the heat displacement due to temperature transfer. There are several problems, such as the failure to effectively compensate for the deviation. The present invention forms a resilient member 20 that compensates for the docking phenomenon due to thermal expansion of the shadow mask 6 by using a shape memory metal so as to more quickly and accurately compensate for the color purity degradation caused by color shift due to thermal expansion of the shadow mask. It is.
