<p>a display composed of an array of light-emitting-elements (118), pixel driving circuits for independently controlling the current to each light-emitting element, display drivers for receiving an input image signal (102) to drive the pixel driving circuits and generating a converted image signal for driving the light emitting elements through signals provided. The current supplied to each light emitting element is dependent upon the voltage between a pair of power lines (104, 110). The voltage supplied by the power lines should be constant, however due to the finite resistance of these lines, an unintended voltage differential is produced along the power line which is proportional to the current conducted. The 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, and sequentially generates a converted image signal for driving the light emitting elements in each region.</p> |
