    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： 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.

    摘要： A panel display has a display panel including a plurality of cells to be selectively discharged to an address driver for setting the plurality of cells to states represented by display data. The panel display also has a display glowing driver for enabling the plurality of cells to glow according to the set states. One frame during which one screen is displayed has a plurality of sub-frames and glowing periods within the sub-frames, during which the display cells are enabled to glow by the display glowing driver. The said sub-frames are weighted in order to achieve gray-scale display. The display panel also has a display load calculating circuit for calculating a display load to be imposed on a whole display surface during each sub-frame. In addition, a corrected period calculating circuit calculates a corrected period of a glowing period, during which the display cells are enabled to glow by the display glowing driver according to display loads to be imposed during each sub-frame. This is calculated by the display load calculating circuit so that brightness attained by the display cells during respective sub-frames will be maintained at a given ratio.
