<p>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. The spacing between the first metal strands defines a plurality of slots (42) substantially parallel to the phosphor lines of the screen. Each of the first metal strands, across the effective picture area of the screen, has a substantially continuous first insulator layer (64) on a screen-facing side thereof. A second insulator layer (66) overlies the first insulator layer. A plurality of second metal strands (60) are oriented substantially perpendicular to the first metal strands and are bonded thereto by the second insulator layer.</p> |
