    Abstract: 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.

    Abstract: A display device, for displaying a multiple-level gray scale picture through a frame having a plurality of sub-frames which are time-divided in accordance with weight value of gray scale for each sub-frame, comprises sub-frame selection circuit, being supplied with an vertical synchronization signal, for selecting the number of the sub-frames which can be displayed within the period for the single frame in accordance with the frequency of the vertical synchronization signal, and for providing a sub-frame selection signal corresponding to the number of the sub-frames; and display control circuit, operatively connected to the sub-frame selection circuit, for receiving the sub-frame selection signal and an input display data signal and for controlling said display of the multi-level gray scale picture in accordance with the selected number of the sub-frames. When the frequency of Vsync. is varied, the optimal number of the subframes are selected so that a number of sustain pulse, conversion table for pseudo-multiple-level gray scale conversion and for duplicated subframe conversion are properly selected.
