Abstract
A faceplate assembly for a color cathode ray tube includes a glass faceplate having on its inner surface a centrally disposed phosphor screen. A metal foil shadow mask is mounted in tension on a mask support structure located on opposed sides of the screen and secured to the inner surface of the faceplate. The support structure according to the invention has an open side facing the screen filled with a reinforcing material effective to render the structure mechanically rigid and prevent flexure of the structure toward the screen under the tension of the shadow mask. A process for manufacturing the inventive structure is also disclosed.
