ABSTRACT:
A front assembly for a cathode ray tube includes a substantially flat faceplate having on its inner surface a centrally disposed phosphor target surrounded by a peripheral sealing area adapted to mate with a funnel. The front assembly includes a stiff faceplate-mounted support structure with a weldable metal surface secured to the inner surface of the faceplate between the sealing area and the target for supporting a high-tension foil shadow mask at a predetermined distance from the inner surface of the faceplate. The mask has a central apertured area and a peripheral area which is welded to the support structure.
