ABSTRACT:
An active matrix electro-luminescent display system, comprising: a display composed of an array of regions of light-emitting elements, pixel driving circuits for independently controlling the current to each light-emitting element, one or more display drivers for receiving an input image signal for data to drive the pixel driving circuits and generating a converted image signal for driving the light emitting elements in each region of the display through signals provided through data lines and select lines, wherein the one or more display drivers sequentially receive the input image signal for driving the light emitting elements within each region of the array of regions, analyzes the input image signal received for each region to estimate the current that would result at, at least, one point along at least one power line providing current to each region, if employed without further modification, based upon device architecture and material and performance characteristics of device components, and sequentially generates a converted image signal for driving the light emitting elements in each region as a function of the input image signal and the estimated currents.
