Abstract— We studied the screening of color phosphor powders on CRT faceplates by photolithography. For photolithography, the phosphor particles should disperse perfectly in the dried PVA‐phosphor screens. The desired pattern sizes and adhesion of the patterned phosphor screens can be calculated with these dried PVA‐phosphor screens. To achieve dry screens with smooth and uniform layers of phosphor particles, phosphor powders should be made with round particles, with the sizes distributed in a narrow range. The phosphor particles perfectly disperse in PVA‐phosphor slurry without the addition of surfactant if an aging process is used. Adding surfactants to the PVA‐phosphor slurry results in the aggregation of phosphor particles in the dried PVA‐phosphor screens, contrary to expectations. Color phosphor screens with a triad pitch of 72 μm have been made with the aged PVA‐phosphor slurry.
