This thesis shows the discharge mechanism and the UV radiation efficiency in one dimensional AC Plasma Display Panel cell. The fluid simulation is used. Under the given condition,4 characteristic steps are found. First, electrons move very fast toward anode and make Xe ions by collision. Second, ions move slowly toward cathode and make the secondary electrons. The Secondary electrons have the same movement and reactions as the first step. Third, the mobility difference between two charged particles makes huge localization of E-field and encourages big ionization-i.e. discharge. Finally, ions and electrons diffuse by ambipolar diffusion. When external voltage is changed its parity,the same steps are begun again.
UV efficiency is caculated. It is about 8% in this simulation. The energy absorbed by ions cannot contribute the excitation which leads UV radiation. The large portion of the energy absorbed yb electrons is used other reactions such as ionization. Wall loss is about 5%, less than the other loss channel.
More researchs are needed.
