  • a plurality of discharge points crossing the gas filled with gas at the crossing points of electrodes an upper member (column electrode) and electrodes on lower member (row electrodes) are formed in the form of a matrix. After discharge point is fired, said fired discharge point has a inherent memory due to a wall charge which adheres to the surface of the dielectric layer.
  • An object of the present invention is to provide a method of driving a plasma display panel whose upper and lower members are not similar in construction and in material by utilizing a minimized write voltage.
  • the write voltage is applied to the Ielectrodes which are covered by a dielectric layer having ansurface of higher secondary electron radiation emissivity with negative polarity and the electrodes which are covered by a dielectric layer having a surface of lower secondary electron radiation emissivity with positive polarity.
  • the pitches or the widths of the column electrodes and the row electrodes are different, the distribution of the electric fields on the surfaces of the dielectric layer covering the column electrodes is different from that covering the row electrodes. Consequently, the electrodes where the electric fields are more concentrated are selected as negative polarity of the write voltage and the electrodes where the electric fields are less concentrated are selected as positive polarity of the write voltage.
