    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: 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: According to the invention, by forming at least every two frames having video contents corresponding to each frame of a video signal, for example, a frame rate of movie contents whose frame rate is equal to 24 Hz is converted into 48 Hz. A plurality of subfields (SFs) corresponding to each frame of the conversion signal are divided into first and second division SF groups. Each division SF group is further classified into an upper SF group on the large weight side and a lower SF group on the small weight side. The weights of the upper SF groups are made symmetrical between the first and second division SF groups. The weight of each SF belonging to the lower SF group in the first division SF is set to be larger than that in the second division SF.
