Different configurations and driving voltages have been employed to investigate theeffect of the wall charge on the striations in macroscopic plasma display panel(PDP)cells.Theexperimental results show that a discharge channel near the dielectric layer is indispensable tostriation occurring in the anode area during a discharge,while the pre-accumulated charge on thedielectric layer and the surface state are not important.The origin of the striation is related onlyto the physical process in the cell.The dielectric layer acts as a charge collector during a PDPdischarge.
