Abstract
A color cathode-ray tube 10 has an evacuated envelope 11 with an electron gun 26 therein for generating at least one electron beam 28. The envelope further includes a faceplate panel 12 having a luminescent screen 22 with phosphor lines on an interior surface thereof. A uniaxial tension focus mask 25, having a plurality of spaced-apart first metal strands 40, is located adjacent to an effective picture area of the screen 22. The spacing between the first metal strands 40 defines a plurality of slots 42 substantially parallel to the phosphor lines of the screen. A plurality of second metal strands 60 are oriented substantially perpendicular to the first metal strands 40 and are insulated therefrom across the effective picture area by insulators 62. The second metal strands 60 are attached by a glass conductor layer 68 to respective right and left first metal end strands 140 outside the effective picture area to form busbars.
