Abstract (en)
A shadow mask for use in a color cathode ray tube (CRT) is described. The shadow mask comprises a multi-aperture masking portion surrounded by a border and a skirt. The border and skirt have cavities across portions of one or more sides thereof. In one embodiment, the border and a portion of the skirt on an outer, screen-facing, surface of the mask have cavities formed therein. Additionally, a portion of the skirt on an inner, gun-facing, surface of the mask adjacent to the perimeter of the skirt may have cavities formed therein. <IMAGE>
