Patent ID: 8223174

Claim:
A display method of a plasma display apparatus carrying out color display by letting three primary color phosphors emit light in accordance with three input primary color video signals, the method comprising: controlling a total number of sustain pulses to be applied in a frame in accordance with an average luminance level of the three primary color video signals for suppressing power consumption; and controlling output grey levels of at least two colors among the three primary color video signals in input of a signal having a predetermined grey level so as to make the output grey levels larger in a case that the total number of sustain pulses in accordance with the average luminance level is a second number larger than a first number than in a case that the total number of sustain pulses is the first number, and controlling the output grey levels, when the total number of sustain pulses is changed from the first number to the second number, so as to make a ratio of a change in the output grey level of a primary color video signal corresponding to a primary color of a phosphor, among the three phosphors, the energy conversion efficiency of which decreases most with increase in the number of emissions of the sustain pulses, larger than ratios of changes in the output grey levels of the other primary color video signals.
