An electroluminescent display system, comprising: a) a display composed of
an array of regions, wherein the current to each of the regions is
provided by a pair of power lines and wherein each region includes an
array of light emitting elements for emitting light; b) a pixel driving
circuit for independently controlling the current to each light-emitting
element in response to an image signal, wherein the intensity of the
light output by the light emitting elements is dependent upon the current
provided to each light emitting element; and c) a display driver for
receiving an input image signal and generating a converted image signal
for driving the light emitting elements in the display, wherein the
display driver analyzes the input image signal to estimate the current
that would result at, at least, one point along at least one of the power
lines providing current to each of the regions, if employed without
further modification, based upon device architecture and material and
performance characteristics of device components, and generates the
converted image signal as a function of the input image signal and the
estimated currents.
