Abstract: Cathode-ray tube comprising an evacuated envelope including a viewing window and a viewing screen comprised of a mosaic of phosphor areas of different emission colors supported on the inner surface of the viewing window. Closely spaced from the screen is a shadow mask having two opposed major surfaces and an array of apertures therein registered with the phosphor areas of said screen. At least one of the major surfaces of the mask and the inner surface of said screen have surface means for effecting faster radiative heat transfer from the central portion of the mask than from peripheral portions of the mask.

Abstract: Method for etching an apertured work piece, such as a shadow mask for a color television picture tube, comprises coating opposite major surfaces of a thin metal sheet with etch-resistant patterns. The pattern on one major surface comprises an array of larger open areas surrounded by etch-resistant material, and the pattern on the opposite major surface comprises smaller open areas of similar shape and registered with the larger open areas on the one major surface. Each of the smaller open areas has therein a still-smaller solid area of etch-resistant material. The coated sheet is then etched from both sides to produce the desired apertures, and then the coatings are removed from the sheet.
