摘要： A wave generation circuit is disclosed, in which a complex waveform can be generated without increasing the ROM data amount or increasing the reading rate. Waveform data relating to a waveform and the generation thereof are stored in a ROM for each cycle. An address signal for reading the waveform data sequentially is produced sequentially by an address generation circuit. The waveform data read out are sequentially reproduced into a waveform signal by a waveform data output circuit. In a wave generating circuit including the ROM and the address generation circuit, the waveform data includes the extension information instructing to extend and reproduce the waveform data for a particular cycle. An extension and control circuit included in the wave generation circuit decides on the presence or absence of the extension information from the read waveform data, and in the presence of the extension information, controls the waveform data output circuit to maintain the output of a corresponding waveform signal while at the same time controlling the address generation circuit to retard the generation of the address signal. The wave generation circuit can generate a single waveform data in an extended form according to the extension information when the same data continues for a plurality of cycles, thereby reducing the waveform data amount and the ROM capacity.

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： 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.
