A full-color display system having improved apparent resolution
comprising: a display formed from an array of full-color groups of
light-emitting elements each comprising more than one luma-chroma
sub-group of light-emitting elements; and 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 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 values for the image signal
corresponding to each luma-chroma sub-group and the control signal.
