The discharge processes and striation phenomenon in large-gap coplanar plasma display panels (PDPs) were investigated by particle-in-cell/Monte Carlo collision. The current pulse on electrodes and the delay time of discharge in simulation are consistent with the experimental results in large-gap PDP cell. Moreover, the current on cathode is mainly by displacement current during the rising edge of the second discharge. The evolution of the second series striations shows that the change in potential causes the striations “suddenly” change from the first series to the second one. The spatial distribution of electron energy and electron energy distribution function (EEDF) are also obtained in the simulation. In the region of striation, the average energy of electrons changes remarkably as the striation forms, and EEDF is similar to that in the negative glow region. Negative glow can be considered as the important region in striation forming.
