摘要： An electrode drive circuit performs interlaced scanning, ensuring that the phases of the sustaining pulse in odd-numbered lines and even-numbered lines among L1 to L8 between surface discharge electrodes are the reverse of each other. With this, when either odd-numbered lines or even-numbered lines are displayed, the voltages applied between the electrodes of the undisplayed lines are at 0, eliminating the necessity for partitioning walls on the surface discharge electrodes. In surface discharge electrodes, X electrodes are provided on the two sides of a Y electrode and the area between the Y electrode and the X electrode on one side is assigned a display line at an odd-numbered frame, and the area between the Y electrode and the X electrode on the other side is assigned a display line in an even-numbered frame. Alternate areas between the surface discharge electrodes are assigned as blind lines and a discharge light emission in the blind lines is blocked or incident light to the blind lines from the outside is absorbed. Address electrodes are provided for each monochromatic pixel column and selectively connected with the pads above them, performing simultaneous selection of lines.

摘要： A plasma display panel that can enlarge the voltage margin and can realize a stable display is provided. The plasma display panel includes first and second display electrodes X, Y for generating surface discharge and address electrodes A that cross the display electrodes via a dielectric layer. In the preparation process of the addressing for forming charge distribution corresponding to display contents, charge forming and charge adjusting are performed. The charge forming generates wall voltage having the same polarity at the same kind of interelectrode of all cells constituting the screen, for three kinds of interelectrodes, an interelectrode XY between the display electrodes, an interelectrode XA between the first display electrode and the address electrode, and an interelectrode YA between the second display electrode and the address electrode. The charge adjusting decreases the wall voltage by applying an increasing voltage that increases continuously or step by step.
