交流型電漿顯示器的二維模擬模型已相當廣泛的應用，但許多變數在二維結構中並無法探討，例如定址電極的寬度、阻隔壁、維持電極形狀… …等等的影響。因此必須發展三維模擬模型才可做更多方面的探討。
本論文研究中發展一套交流型電漿顯示器的三維流體模型。藉由解帕松方程式 (Poisson’s equation)可得空間中隨時變的電位分布，而各粒子的密度分部則是由連續方程式得到。離子部分採用局部電場近似法假設來簡化計算，但由於此近似法對於電子誤差較大，因此使用能量守衡方程式來計算電子能量。由數值方法雙共軛梯度穩定法(BI-CGSTAB)解以上矩陣。
本論文中，利用此三維模型來探討三種維持電極結構並搭配方塊型阻隔壁的放電。文中提出新型的Y型電極，可提高在陽極的發光效率,並且對於整個槽中的效率也有提升。配合方塊型阻隔壁，新的Y型電極比起傳統型電極可提高23.36%的發光效率，而比起T型電極則可提高10%的發光效率。
本三維模型由於邊界的假設以及矩陣龐大造成數值誤差，在峰值處邊界有不穩定現象發生，不影響整體放電現象但可藉由考慮更多方向的邊界並配合硬體的升級加以改進以獲得更準確的模擬成果。

Two dimensional simulation code of AC-PDP has already been widely used to understand the micro-discharge characteristics in the plasma display cell, but there are many variations can not be changed or investigated by the two dimensional simulation, i.e., the width of the address electrode, the effect of barrier ribs, and the shape of the sustain electrodes. Therefore, a three dimensional simulation is necessary for more research.
A three dimensional simulation code of AC-PDP based on the fluid model has been developed in this research. The voltage varied with time in the cell are solved by the Poisson’s equation, and the electron energy balance equation is considered to obtain the electron temperature precisely. For all the other particles, including the excited species and ions, the Local Field Approximation (LFA) is used to simplify the calculation. The momentum transfer equation and the continuity equation are applied to determine the densities of all the particles in the cell, and all the parameters are solved time-dependently by the numerical method bi-conjugate gradient stabilized algorithm (BI-CGSTAB).
In the thesis, the three dimensional model will be utilized to study on the effects of different structures of sustain electrode with the WAFFLE cell structure. The new Y-shaped electrode is proposed in the thesis and can utilize the anode region more and utilize the whole cell more efficiently. The new Y-shaped electrode combined with WAFFLE cell can achieve an efficiency improvement of 23.36% to the conventional electrode and 10% to the T-shaped electrode.
