Pdp Adjacent Unit Discharge Impact Studies

Plasma Display Panel (PDP) has the advantage of high brightness, high contrast, wide viewing angle, full color, etc. It's a promising candidate for the large screen high-definition (HD) display. More efforts are paid to improve its performance, such as high luminous efficiency, high resolution, long life time. The experimental research of plasma discharge in PDP cell has many limitations due to the small cell size and short discharge time. Therefore, numerical simulation is a useful tool for understanding the plasma discharge behavior in order to optimize cell parameters.Two-dimensional fluid model is used to simulate adjacent pixels'discharge process of surface-discharge PDP and shadow-mask PDP (SM-PDP) with different structure in this paper. Average density and density distribution of electron and resonance Xenon are presented. The radiation and capture process of resonant photos is studied by Monte Carlo method. The distribution of photons on the phosphor layers of corresponding cell is also calculated The cross-talk of adjacent pixels are studied for various kinds of PDP structure. For conventional strip-type surface-discharge PDP structure, cross-talk is increased as the electrode gap, electrode width and pixel height increased. Waffle rib structure can prevent this effectively, and cross-talk is decreased by increasing rib height. For shadow-mask PDP, cross-talk is tiny.
