Patent ID: 7965305

Claim:
A full color display system comprised of: a) a display which is formed from a two-dimensional array of three or more differently colored light-emitting elements arranged in a repeating pattern forming a first number of full-color two-dimensional groups of light-emitting elements arranged in rows and columns, each full-color group of light-emitting elements being formed by more than one luma-chroma sub-group of light-emitting elements wherein each luma-chroma sub-group in a full-color group comprises a spatial arrangement of at least two light-emitting elements, wherein 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 and at least one distinct low-luminance light-emitting element having a peak output luminance value that is less than 40 percent of the peak white luminance of the display device; and b) a processor for providing a signal to drive the display by receiving a three-or-more color input image signal that specifies three-or-more color image values at each of a two-dimensional number of sampled addressable spatial locations within an image to be displayed: wherein the processor dynamically forms re-sampling functions for image spatial locations derived from the input image signal that; i) correspond to the known spatial location of each luma-chroma sub-group in the display array; ii) are dependent upon the similarity of the three-or-more color input values at two or more neighboring spatial locations of the image input signal; iii) are based on an analysis of the spatial content of the three-or-more color input image signal and the display array repeating pattern wherein the analysis comprises a thresholding of a calculation of an absolute difference between a luminance value for a spatial location to be rendered to a corresponding luma-chroma sub-group and the luminance values of the two or more neighboring spatial locations of the image input signal; and iv) are implemented by convolving highly non-symmetrical kernels with the input image signal wherein the kernels are dynamically formed matrices based on the spatial content of the input image signal by assigning a first weighting value to a center element of the kernel, assigning a second value to the remaining elements of the kernel for which the corresponding three-or-more color input image signal has a similarity to the three-or-more color image signal corresponding to the center element of the kernel, and assigning a third value to the remaining elements of the kernel, wherein the second kernel value is substantially larger than the third kernel value; v) applies the re-sampling functions to the three-or-more color input image signal to render a signal for driving each light-emitting element within each corresponding luma-chroma sub-group of light-emitting elements.
