The properties and characteristics of micro-scale Capillary Plasma Electrode Discharges(CPEDs) were investigated. We examined the basic discharge characteristics of AC-type microscale CPEDs as a function of the L/D ratio. Using the basis of the previous findings, we applied the CPED concept to the design of a commercial plasma display panel and compared the discharge characteristics with those of a conventional DBD-based PDP. The optimum parameters for micro-scale CPED are L/D ratio = ∼0.5, diameter (D) = 125 μm, length (L) = 70 μm, total dielectric thickness (T) = 90 μm. The luminous efficiency of the optimized CPED structure is higher than that of DBD structure with same dielectric thickness. However, by comparison with DBD structure with T= 45 μm which is somewhat higher dielectric thickness than current conventional PDP (T= ∼30 μm) but has almost similar discharge characteristic, there is no noticeable difference in the luminous efficiency.
