Abstract
The plasma display panel is made of many small discharge cells, which consist of a discharge space between the cathode and anode. An electrical discharge occurs in the discharge space filled by neon and xenon gases. The electron temperature is determined from the sparking criterion, which theoretically estimates the electrical breakdown voltage in terms of the xenon mole fraction. The plasma in the cell emits vacuum ultraviolet lights of 147 nm and 173 nm, exciting fluorescent material and converting VUV lights to visible lights. The physical mechanisms of all these processes have been theoretically modeled and experimentally measured. The theory and experimental data agree reasonably well. However, new materials and better configuration of cells are needed to enhance discharge and light emission efficiency and to improve the PDP performance.
