Abstract
In plasma display panels(PDPs), the resonance radiation trapping is one of the important processes. A self-consistent two-dimensional radiation transport model is coupled with a fluid simulation to represent 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 distribution with time 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 visible photon fluxes reaching the output window from the phosphor layers as well as the total UV photon fluxes arriving at the phosphor layer from the plasma region are calculated for resonant and nonresonant excited species. From these calculations. The visible light efficiency in PDP is obtained. Finally, the waveforms with the ramp-typed sustain voltage and the auxiliary address pulse is proposed to improve the visible light efficiency. Considering the RT model instead of TFA model, we found that the number of the Xe*(3P1) density is modified, and the visible light efficiency is modified further. By increase the rise-time of sustain pulse, the visible light efficiency can go up to 47% higher than the conventional waveform. Moreover, add auxiliary pulses on address electrode incorporate with the long rise-time sustain waveform; the luminous efficiency can be further increased up to 78.8% higher than the conventional waveform.
