Abstract:
1. A display method of a plasma display apparatus carrying out color display by letting phosphors for a plurality of primary colors emit light in accordance with a plurality of primary color video signals, the method comprising the steps of: setting a luminance of a display image through a luminance adjustment input from outside for adjusting a display image luminance; changing a total number of sustain pulses in a frame depending on the luminance adjustment input; changing gray levels of the primary color video signals when the total number of sustain pulses in the frame is changed, by making a ratio of change from before alteration of output gray levels of one primary color video signal among the plural primary color video signals different from ratios of change in gray level of the other primary color video signals in order to correct a white balance failure of a display image; and displaying an image by letting the phosphors emit light in accordance with the primary color video signals with the changed gray levels, wherein regarding one primary color video signal having at least the longest persistence characteristic among the plurality of primary color video signals, a case where the total number of sustain pulses changes in a decreased direction is larger in ratios of change than a case where the total number of sustain pulses changes in an increased direction.
