A novel ink-jet printing method was investigated for fine patterning of Ag electrode and phosphor layer in PDP using the precision nozzle. Both silver ink and absorbent layer paste formulation were developed for ink-jet printing of electrode pattern. The ink-jet printing of silver electrode with preformed absorbent layer was especially suitable for the patterning of address electrode for high resolution PDP. A reverse emulsion method was developed for the synthesis of nano-size phosphor powder that could be formulated in the phosphor ink. The composition of the phosphor ink including charge control agents, solvent, dispersant and nano-size phosphor powder was optimized for the fine patterning of phosphor layer for high resolution PDP.
