Abstract
A novel discharge device is designed on the basis of the configuration of micro-hollow cathode discharge (MHCD). 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/cm3, the power density is 3.6 × 104 W/cm3, and the electron density is in the order of 1013 cm−3 atp=200 Torr andI D=10 mA. The experimental results indicate that the designed discharge device is appropriate for PDP.
