Abstract
A shadow mask frame assembly includes hook springs made of a plate-like bimetal member whose outer side is a high-expansion side and inner side is a low-expansion side, is fixed on a frame in the direction of an electron beam proceeding axis, and is nearly L-shaped to have a fixing portion welded to the base of the frame and a fitting portion having a fitting hole into which a stud pin on the inner side of a panel is fitted. The shadow mask frame assembly is not distorted or rotated with respect to the panel during the thermal expansion of a shadow mask due to electron beam collision, and is sufficiently compensated only in the direction of the electron beam's proceeding axis.
Claims14
A shadow mask frame assembly comprising:
- a shadow mask,
- a frame fixed to said shadow mask,
- a panel enclosing said shadow mask and said frame, said panel having an inner surface facing said shadow mask and said frame, and an outer surface;
- a plurality of stud pins disposed on said panel;
- and
- a plurality of hook springs fixed to said frame, each of said hook springs being coupled with a stud pin on an inner surface of said panel,
- wherein said hook springs define a plate-like bimetal member having a high-expansion outer side and a low-expansion inner side, said hook spring being fixed on said frame in the direction of an electron beam axis, and said hook spring being nearly L-shaped, having a first portion defined as a fixing portion welded to said frame and a second portion defined as a fitting portion having a fitting hole into which a stud pin disposed on the inner surface of said panel is fitted.
A shadow mask frame assembly comprising:
- a shadow mask;
- a frame affixed to said shadow mask;
- a panel encompassing said shadow mask and said frame;
- a plurality of stud pins disposed on an inner portion of said panel;
- and
- a plurality of hook springs, each of said hook springs including a bimetal member having a high-expansion side and a low expansion side, the bimetal member being substantially L-shaped, having a first portion defined as a fixing portion that is secured to said frame, and a second portion defined as a fitting portion coupled with a stud pin, the fitting portion being disposed substantially perpendicular to said shadow mask.
