Abstract
A face plate for a cathode ray tube display is produced by a method in which small holes are formed through a sheet of unfired ceramic tape. The holes are arranged in a desired pattern for the location of pixel dots. The holes are filled with generally transparent glass to form plugs in the desired pattern. The ceramic tape is cured to a hardened state by firing to an appropriate temperature. Each plug is coated at an inner, anode side of the face plate with phosphor of appropriate color.
