COMPOSITE SHADOW MASK AND CATHODE RAY TUBE INCORPORATING SAME |
摘要 |
A color CRT has a shadow mask formed from a bilayer composite of steel and invar. The thicknesses of steel and invar are chosen to take advantage of the lower thermal expansion coefficient of invar and the room temperature formability and higher modulus of elasticity of steel. Such composite masks exhibit reduced doming when compared to steel masks, and can be formed at room temperature.
