    摘要： The present invention relates to a plasma display device which limits a generation of electromagnetic wave. The plasma display device has first and second drive circuits for applying a drive voltage to first and second display electrode pair. Further, a direction of a charge current flowing at said first display electrode pair when said drive voltage is applied by said first drive circuit is opposite on said plasma display panel to a direction of a charge current flowing at said second display electrode pair when said drive voltage is applied by said second drive circuit. According to the present invention, a transitional charge/discharge current, which is generated upon the application of a drive voltage to one of the display electrodes, and a light emission discharge current flow in opposite directions on the panel. Thus, electromagnetic waves that are generated by the inductances of the display electrode pair cancel each other out. In addition, the currents flowing in opposing directions cancel each other out on the common ground wirings which are connected to the ground wirings of the drive circuits, and electromagnetic wave is reduced.

    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 PDP not posing the problem that previous display data appears at the time of activation, and a wave generating circuit capable of generating a complex wave without the necessity of expanding a quantity of ROM data and of increasing a reading speed have been disclosed. A plasma display panel display comprising a plasma display panel that includes a plurality of cells to be selectively discharged to glow, a reset unit for bringing the plurality of cells to a given state, an addressing unit for setting the plurality of cells to states associated with display data, and a sustaining discharge unit for enabling the plurality of cells to glow according to the set states further comprises an operation halt factor detector for detecting the fact that a factor of halting the operation of the plasma display panel has occurred, and an initialization unit that when it is detected that the operation halt factor has occurred, initializes memory information in the plasma display panel. In a wave generating circuit for generating a wave on the basis of ROM data that is stored in a ROM and concerned with a wave and its generation, the ROM data is stored while being split into basic period data that changes at intervals of a basic period and long period data that changes at intervals of a long period data. The basic period data and long period data are read at intervals of associated periods and converted at intervals of associated periods.
