Abstract:
1. A full-color display system having improved apparent resolution comprising: a) a display formed from a two-dimensional array of three-or-more colors of light-emitting elements, the light-emitting elements arranged in a repeating pattern to form a number of full-color groups of light-emitting elements, each full-color group of light-emitting elements comprising more than one luma-chroma sub-group of light-emitting element; and b) a processor for receiving a full color input image signal that specifies full color image values at each of a two-dimensional number of sampled addressable spatial locations within an image to be displayed, for providing a full color image signal with different image signal values corresponding to the spatial location of each luma-chroma sub-group, for computing a control signal representing the relative values, or difference between values, for the image signal values corresponding to each luma-chroma sub-group and at least one of each luma-chroma sub-group's neighbors, and for rendering a signal for driving each light-emitting element within each luma-chroma sub-group of light-emitting elements as a function of the full color image signal values corresponding to each luma-chroma sub-group and the control signal, such that the display has a peak white luminance and each luma-chroma sub-group comprises at least one distinct high-luminance light-emitting element having a peak output luminance value that is 40 percent or greater of the peak white luminance of the display device.
