摘要： 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.

摘要： In a conventional image display apparatus, since display load ratios for respective lines are different, voltage drop amounts are also different and a difference in brightness occurs in spite of giving the same inputted luminance signal, so that image quality of display image is degraded. In the case where signals at the same luminance level are inputted and displayed, for a pixel on a display panel, an ON pattern of a subfield in one field is changed when a line load ratio of a line including the pixel is changed. That is, an image display apparatus using a display panel having a plurality of pixels is configured so as to include, for each of the plurality of pixels connected to one driving electrode, a load calculating means that calculates the load ratio and a luminance correcting means that calculates a drop amount in luminance level of an inputted video signal for correction.
