Plasma display panel with micro-discharge array |
|
|
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. |
