碩士 === 國立清華大學 === 工程與系統科學系 === 94 === 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.
