    摘要: Power consumption control is performed that does not induce unnatural changes in brightness even when data causing an abrupt change in load ratio is input, and that can make the power consumption settle down to the desired value. The load ratio is calculated from data input to a display apparatus, and the load ratio is again calculated this time backward from the present brightness value; if the difference between the two calculated values is greater than a threshold value, a new brightness value is calculated from the load ratio, and the brightness is set to the newly calculated value. Thereafter, the brightness is controlled based on measured power consumption values.

    摘要: The plasma display device has a plasma display panel and a driving part for driving the plasma display panel in a subframe mode. The driving part has a circuit for calculating the length of one frame based on one period of a vertical synchronizing signal introduced along with an image signal from an external device, a circuit for calculating the total number of sustaining pulses contained in one frame based on a brightness information contained in the image signal, and a circuit for calculating the length of one driving period required for displaying one frame. The length of one frame and the length of one driving period thus obtained are then compared in a comparing circuit. If the one frame length is found to be shorter than the one driving length, the total number of sustaining pulses or the number of scan lines will be reduced so that the one frame length becomes shorter than the length of one driving period, thus avoiding an extraordinary display.

    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.
