Abstract (en)
An improved color picture tube (8) includes an evacuated envelope (10) having a rectangular faceplate panel (12). The panel includes a viewing screen (22) on an inner surface thereof and a shadow mask (24) mounted therein. The shadow mask includes an apertured contoured portion (26) and a reinforcing structure (42) peripherally attached to the apertured portion. The reinforcing structure and a portion (30) of the mask form a box-like enclosure (43) around the periphery of the mask. The reinforcing structure is constructed of a material that has approximately the same thickness as does the material of the apertured contoured portion of the shadow mask. <IMAGE>
