Abstract:
1. A plasma display panel which displays colors by exciting a plurality of fluorescent substances of different colors using ultra-violet rays generated during discharges, comprising: a drive unit which monitors a change of a display load factor of the panel, receives image signals of said different colors and drives areas of different colors in a pixel in the panel according to intensities of the image signals so as to have the areas emit light with emission intensities corresponding to the intensities of the image signals, while controlling to decrease a drive frequency of sustain discharges as the monitored display load factor increases and to increase the drive frequency of sustain discharges as the monitored change in the display load factor decreases, said drive frequency of sustain discharges being in common to said areas of different colors, wherein said drive unit makes a correction to change an intensity of the image signal of a predetermined color, independently of another color, depending on the monitored change of the display load factor, and drives all of the areas in the panel according to the corrected intensity of the one image signal, so that a ratio of the emission intensity of said fluorescent substance of each color during a white display is roughly the same when said display load factor is low and high.
