Investigation of Discharge Phenomena in a Cell of Color Plasma Display Panel I. One-Dimensional Model and Numerical Method

Abstract

A numerical simulation method using a one-dimensional fluid model under the local field approximation is presented in order to understand pulsed-dc discharge in He–Xe gas mixture in a cell of a full-color plasma display panel. Spatiotemporal behaviors of the electric field and number densities of twelve independent particles, including electrons and four kinds of ions, were calculated self-consistently at a gas pressure of 200 Torr (27 kPa) and an electrode distance of 0.02 cm. The imprisonment of 147-nm-resonance radiation, the excitation source of phosphors, was also taken into account. Calculated results of the discharge current and voltage are consistent with those of experiment. The waveform of 147-nm-resonance radiation agreed well with experiment, although that of the discharge current showed some difference, probably due to the local field approximation.

Improvement of luminance and luminous efficiency for optimal Penning gas mixtures in alternating current plasma display panels

“…11 As in Ref. [11][12][13][14] Table II shows the rate constants of Penning reactions used in this simulation. We considered only electron impact reactions among the chemical reactions including Kr, because of the lack of data related to Kr.…”

Calculation of Ion Mobilities and their Effects on Gas Discharge of AC Plasma Display Cells

“…We noticed that the mobility of an atomic ion in its own gas, e.g., He þ in He gas, is mostly determined by symmetric charge exchange between the ion and the gas atom because the cross section of this process is very large. [17][18][19] On the other hand, the mobility of a molecular ion is governed by elastic collisions that result from the polarization force [18][19][20] and charge exchange collisions become negligible. In such a case, the ion mobility would be $ ðMÞ À1=2 ; ð3:1Þ…”

“…where M is the reduced mass which is deduced from masses of the ion and the gas atom and is the polarizability of the gas. We assumed, as Takahashi et al did, 19) that the charge exchange collisions are negligible for atomic ions in the foreign gas just as they are for molecular ions in order to determine atomic ion mobilities in a foreign gas that are not available experimentally. With this assumption, we determined all the necessary atomic ion mobility values for the simulations of PDPs with the He-Ne-Xe mixture, using known values and eq.…”

He–Xe microdischarges: Comparison of simulation results with experimental data

“…Experimental studies of plasma discharges in PDPs are extremely difficult due to the very small cell dimensions and complicated panel structure. 3,5,[10][11][12][13][14][15] As in Meunier, Belenguer, and Boeuf, 5 a Holstein escape factor is used to describe the lengthening of the apparent lifetime of the resonant state Xe*( 3 P 1 ) due to radiation trapping, and the resonance radiation is assumed to be optically thin. Such measurements can also be used for the validation of simulation models.…”
