    摘要： The present invention provides a flat display including a high-speed arithmetic logic facility so that, even when a data signal for a first line follows immediately after a frame start signal, the display displays an image with stable display quality quickly. For controlling driving signals in a flat display, each sub-frame of a temporally-segmented frame comprises at least an initialization period S1' during which a display screen is initialized, an addressing period S2 during which a plurality of cells are selected and written with display data, and a sustaining discharge period S3 during which the cells which contain display data are discharged so as to emit light for a given period of time. The flat display includes an initialization start time control unit 100 that detects the input of a display start signal V.sub.SYNC for one frame, and controls an initialization start time ST of the initialization period S1' so that the ST will precede an instant of input of a frame start signal V.sub.SYNC.

    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 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.

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.
