Two-dimensional self-consistent radiation transport model for plasma display panels

Abstract

A two-dimensional radiation transport model is coupled with a fluid simulation to incorporate the resonance radiation trapping effect in a plasma display panel cell. Compared with the conventional trapping factor approach, this model has an advantage in describing the spatial evolution of the radiative excited-state density. Compared with a Monte Carlo model, it also takes advantage of its fast computation to couple the radiation transport self-consistently with the time-dependent fluid model. The effect of the spatial evolution of the resonant excited state on the light emission is investigated for the variations of system sizes and the gas mixture ratio, and the results are compared with those of the conventional trapping factor approach. The discrepancy between the two methods increases as the gap size between the dielectrics increases, but does not change significantly for the variation of the gas mixture ratio.

The effect of electrode tilt angle on the characteristics of coplanar dielectric barrier discharges with Xe-Ne mixtures

“…Three equations, the continuity equation, momentum conservation equation, and Poisson's equation, are used in the simulation. 17,20,21 The continuity equation for the particle density balance is…”

“…A number of simulation results revealing the underlying physics of a PDP discharge have been published in previous studies.

Two‐DimensionalKinetic and Three‐Dimensional Fluid‐Radiation Transport Simulations of Plasma Display Panel

“…To do this, we utilize 2-D and 3-D fluid codes [16,17]. Usually, 2-D code is used first for optimization.…”

“…To do this comparison, we took into account the effect of radiation transport and the molecular ions like Xe + 2 , Ne + 2 , and NeXe + in our 2-D and 3-D fluid simulation codes. To describe the resonance radiation transport of UV emitted from Xe * ( 3 P 1 ), we use the modified Holstein's equation instead of the effective trapping factor method [16,17]. Molecular ions are generated by three-body collisions and Penning ionization of metastable Ne atoms or metastable Ne molecules.…”

Application of two-dimensional numerical simulation for luminous efficiency improvement in plasma display panel cell

“…Since the 147-nm UV line is the dominant line in the emission spectrum, the redistribution of Xe P density is very important. Instead of the conventional trapping factor method [22], we have considered a self-consistent radiation transport model coupled with 2-D and 3-D fluid simulation using the Holstein equation [28], [29] (5)…”
