A full color electro-luminescent display system, comprising: a display
device comprised of a plurality of red, green, blue light-emitting
elements and at least one additional color of light-emitting element
having luminance efficiency greater than at least one of the red, green
and blue light-emitting elements, wherein the light-emitting elements are
laid out over a substrate in adjacent columns arranged along a first
dimension and adjacent rows arranged along a second dimension, such that
each pair of adjacent columns of light-emitting elements, and each row of
light-emitting elements, contain each of the red, green, blue and
additional color light-emitting elements; and a controller for receiving
an input signal for an input image having a two-dimensional spatial
content including edge boundaries between first and second regions of the
input image and driving the display, the controller being responsive to
the two-dimensional spatial content of the input image and increasing
apparent display resolution while providing increased display power
efficiency.
