CRT tension mask support structure

摘要

A faceplate assembly for a color CRT includes a glass panel with a phosphor screen thereon and a plated mask support structure attached to the faceplate, with a foil shadow mask welded in tension to the mask support structure. The mask support structure comprises an inert substrate to which is electroformed a weld land suitable for accepting welds and retaining the mask thereby. A minimal amount of metal is used and the shape and size of the mask support are readily controllable.
