Abstract
A display method of a plasma display apparatus to which primary color video signals are inputted and which carries out color display by letting phosphors for primary colors emit light is provided. The display method displays the primary color video signals by changing a gray level of an output primary color video signal in accordance with a gray level of an input primary color video signal. When each gray level of the inputted primary color video signals changes from a first value to a second value which is larger than the first value, a gray level of a primary color video signal for a phosphor having the largest influence of luminance saturation properties among the phosphors is increased relative to a gray level of the other primary color video signal.
