  • Publication number: 20130229447
    Abstract: Sticking of a Pixel is suppressed to improve the life of a display panel. 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.

  • Patent number: 8471787
    Abstract: A display method of an emission display apparatus including a display panel in which a plurality of pixels each having at least one subpixel are disposed, includes a first display method of performing the display of an image input data with only a subpixel using emission luminance, and a second display method of performing the display of the image input data with a nearby subpixel group. A display according to the second display method is performed with the emission luminance distributed to the subpixels of the nearby subpixel group, wherein a display is performed using an intermediate mode in which the first display method and the second display method are combined with a variable combination ratio.
