“…Another reason is that 3-D code is very time consuming in comparison with 2-D code. Therefore geometrical cell optimization is done with 2-D fluid code and then some models showing good efficiency are simulated with 3-D code in order to obtain detailed information [21]. However, a real PDP cell has 3-D structure, so 2-D fluid code has some limitations to analyze it elaborately.…”

Using fluid and kinetic simulation codes, we investigated ion angle distributions in a PDP cell. We also compared our fluid simulation results with experimental data to prove the accuracy of our codes and suggested new PDP cell structure. Kinetic simulation results shows that most ions impinge on the MgO surface at the cathode region with the incident angles in the range of 10• ∼30• . Our simulation results from 2-D and 3-D fluid codes showed good agreements in the distribution of excited Xe atom density compared to the experimental data measured by laser absorption spectroscopy. Using these fluid codes, we suggested Front Address PDP cell structure. This structure has address electrode on the upper substrate and shows the improvement of luminous efficiency about 2 times in comparison with conventional model because of the arch-shaped long discharge path between two sustain electrodes.

“…Rauf and Kushner [58] show that the efficiency decreases with increasing He content; however, Lee et al [59,60] find it to decrease. For the improvement of the luminous efficiency from the structural point of view, several approaches have been tried so far [61][62][63][64][65][66][67][68][69][70][71][72][73][74][75][76][77][78]. The increase of the distance between the sustain electrodes (gap), the thickness of the dielectric that covers them or the decrease of their permittivity induces a better luminous efficiency [57,[79][80][81][82][83][84][85].…”

Plasma display panels (PDPs) are one of the leading technologies in the flat panels market. However, they are facing intense competition. Different fluid models, both one-dimensional (1D) and 2D, have been used to analyze the energy balance in PDP cells in order to find out how the xenon excitation part can be improved to optimize the luminous efficiency. The aim of this work is to present a 1D particle-in-cell with Monte Carlo collision (PIC–MCC) model for PDPs. The discharge takes place in a Xe10–Ne gas mixture at 560 Torr. The applied voltage is 381 V. We show at first that this model reproduces the electric characteristics of a single PDP discharge pulse. Then, we calculate the energy deposited by charged particles in each collision. The total energy is about 19 μJ cm−2, and the energy used in xenon excitation is of the order of 12.5% compared to the total energy deposited in the discharge. The effect of xenon content in a Xe–Ne mixture is also analyzed. The energies deposited in xenon excitation and ionization are more important when the xenon percentage has been increased from 1 to 30%. The applied voltage increases the energy deposited in xenon excitation.

In order to incorporate this effect in a PDP cell, a three-dimensional radiation transport model is self-consistently coupled with a fluid simulation. This model is compared with the conventional trapping factor method in gas mixtures of neon and xenon. It shows the differences in the time evolutions of spatial profile and the total number of resonant excited states, especially in the afterglow. The generation rates of UV light are also compared for the two methods. The visible photon flux reaching the output window from the phosphor layers as well as the total UV photon flux arriving at the phosphor layer from the plasma region are calculated for resonant and nonresonant excited species. From these calculations, the time-averaged spatial profiles of the UV flux on the phosphor layers and the visible photon flux through the output window are obtained. Finally, the diagram of the energy efficiency and the contribution of each UV light are shown.
