ABSTRACT:
A shadow mask adapted for tensioned mounting in a flat faced color CRT is characterized by having a pattern of slits in the border regions of the mask in order to provide uniform distribution of tensile stresses across the mask when mounted in the CRT, resulting in improved mechanical and thermal behavior, and enabling the separate fabrication of the mask and display screen of the CRT.
