In an emission display apparatus with a display panel in which a plurality of pixels each having at least one subpixel are disposed. A first display method of emitting light with only a pixel P(i,j) serving as an emission center and a second display method of allocating luminance of the pixel P(i,j) serving as an emission center to nearby pixels surrounding the pixel are combined in a controllable manner. A high-resolution mode with a high ratio of the first display method and a long-life mode with a high ratio of the second display method are switched therebetween depending on a spatial change or time change of image input data, an emission time, a degradation rate, a temperature, an emission luminance, and a display time. | 02-26-2009 |
