By using many MHCDs in parallel connection, a micro-discharge array can be constructed. With the micro-discharge array, a high-pressure high-current density glow discharge plasmas can be formed to make a plasma display panel （PDP）. An air discharge experiment is finished with the discharge device. The stable direct current glow discharge is formed under the pressure from 20 Torr to 500 Torr. The voltage-current characteristic curve and the discharge photograph are noted. The voltage-current characteristic curve has a positive differential resistance coefficient on the whole discharge range. The estimated current density reaches 70.1A/cm^3, the power density is 3.6×10^4 W/cm^3, and the electron density is in the order of 10^13 cm^-3 at p = 200 Torr and ID = 10 mA. The experimental results indicate that the desiclned discharqe device is appropriate for PDP.展开更多
