| 6. A method used in conjunction with displaying an image on a display panel, said display panel comprising a subpixel repeating
group including at least one white subpixel and a plurality of primary color subpixels, where the method generates image data
signals that substantially define an image to be rendered onto said display panel, and said method comprises:
receiving and storing input image data signals that are to be used for rendering a corresponding image on said display panel;
computing an output luminance value for each subpixel of an individual color plane by multiplying data values of a spatial
portion of said input image data signals by at least one image filter kernel, said each individual color plane being formed
by white subpixels and by same-colored primary color subpixels; said image filter kernel comprising a matrix of coefficients
arranged such that each coefficient represents a fractional part of one of said data values of said spatial portion of said
input image data;
sharpening said output luminance values with a luminance signal; and
producing the generated image data signals from the sharpened output luminance values.
