Abstract:
1. A method of manufacturing a cathode-ray tube comprising an evacuated envelope having therein an electron gun for generating an electron beam, a faceplate panel having a luminescent screen with phosphor elements on an interior surface thereof, and a focus mask, wherein the focus mask includes a plurality of spaced-apart first conductive strands, and a plurality of spaced-apart second conductive wires oriented substantially perpendicular to the plurality of spaced-apart first conductive strands, comprising the steps of: applying an insulating material to the plurality of spaced-apart first conductive strands, wherein the insulating material comprises a low porosity lead-zinc-borosilicate glass formed from a lead-zinc-borosilicate glass powder having a median particle size less than about 1 μm; and bonding the plurality of spaced-apart second conductive wires to the insulating material.
