A one dimensional AC Plasma Display Panel(PDP) Cell is de\-scribed. In AC type Plasma Display Panel, ordinary wave-form of external Voltage source is 50 KHz Square wave. At every half period, Plasma discharge is occurred in a few hundred nano-seconds, and then calm down.
In this paper, this transient discharge mechanism is shown by Computer Simulation. We find, discharge mechanism is made up four steps. For the first time, electrons drift to wall very fast. Then, secondary emission electrons, which produced at cathode, travel to anode with ionization. Third, because of high density of ion and low density of electron, the cell becomes positively charged, and Electric field is highly deformed. This electric field guide to big ionization - i.e. discharge. Finally, ions and electrons produced at third step, diffuse by ambipolar diffusion mechanism. At the end of this long final step, external voltage is change its parity. It makes subsequent discharge.
In this way, we learn discharge mechanism of micro-discharge cell. We will study about power consumption in this transient discharge later, and hope that this work help next research.
