NUMERICAL-ANALYSIS OF THE MICRODISCHARGE IN A DC PLASMA DISPLAY PANELBY 2-DIMENSIONAL MULTIFLUID EQUATIONS

A numerical analysis of the microdischarge in a plasma display panel h ave been made by using 2-dimensional multifluid equations, The dischar ge gas is used as Ne + Ar 0.1% in a state of non-LTE glow, The distrib utions of the microscopic variables such as the density, temperature, velocity of the charged particles and the density of the uncharged par ticles are obtained, The distributions of excited species are examined during glow and afterglow, From the simulation results, the nondischa rge pulses applied to the auxiliary anode confine the plasma to the co re of the microdischarge, It is found that metastable species and othe r excited species are locally confined around the auxiliary anode duri ng glow and afterglow, Locally confined particles indirectly due to th e nondischarge pulses play a role to improve the characteristics of th e DC plasma display panel.
