ABSTRACT:
This invention relates to an elastic support device for a shadow mask of a color picture tube which is able to minimize stress of elastic members resulting from thermal expansion of the shadow mask during operation of the color picture tube. Thus, the compensation for mislanding of an electron beam emitted to a screen is improved. The device includes a first elastic member having a first end thereof fixed to the frame and coupled at a second end thereof to a panel pin, wherein the panel pin is secured to the panel, thereby exerting elastic force upon the frame and a second elastic member having a first end thereof slidably coupled with the frame and a second end thereof to the first elastic member, thereby exerting auxiliary elastic force upon the frame.
