An investigation of a cell-wall charge effect in a PDP cells by a cylindrical coordinate system simulation for a PDP

Abstract

In order to improve the discharge characteristics of a plasma display panel(PDP), we constructed a cylindrical coordinate system simulation for a PDP based on the axial symmetric 3-dimensional fluid model. The accumulation of charge was examined as one of the cell-wall effects under the condition of DC-voltage application. The distribution of charge weakened the radial electric field at the steady state, thereby reducing loss of ions. It was shown that the peak of the particle-density distribution moves generally toward the cathode, when viewed in terms of charge accumulation on the cell wall.
