Color cathode ray tube |
摘要 |
A color CRT suppresses deformation of the main shadow mask surface after fastening the shadow mask to the mask frame. Numerous substantially rectangular grooves or substantially circular recesses are formed in the damper part disposed to the shadow mask skirt so that the bending strength in the circumference direction of the skirt is greater than the bending strength in the direction parallel to the tube axis.
