Abstract RCA 73,079 The present invention provides an improvement in an apertured mask type color picture tube having a faceplate, a cathodoluminescent screen on the faceplate, a corrugated apertured mask adjacent the screen and an electron gun means for producing and directing a plurality of electron beams through the mask to impinge upon the screen. The mask is constructed by first forming the apertures therein and thereafter forming the mask in a corrugated shape. Aperture width in the apertured but unformed mask is adjusted to compensate for stretching and compression of the mask occurring during formation of the mask into a corrugated shape. Therefore, the corrugated mask is substantially free of aperture width variation (from that desired) caused by forming the mask in a corrugated shape.
