Claim One:
1. A method for driving a multiple pixel display, the method comprising: performing any of the following with a processor: displaying, sequentially in time, a plurality of test pattern images on a multiple pixel display, wherein each test pattern image in the plurality of test pattern images defines respective intensity values for each of at least three pixels, wherein each respective intensity value of the each of the at least three pixels of each test pattern image is different from one another, wherein the respective intensity value in each test pattern image for a particular pixel is different from the respective intensity value of the particular pixel in other test pattern images within the plurality of test pattern images; determining, while displaying each test pattern image of the plurality of test pattern images, a respective value of measured total electrical current consumed by the multiple pixel display; determining a plurality of electrical current value differences, each electrical current value difference within the plurality of electrical current value differences comprising a difference between a respective baseline electrical current and the respective value of measured total electrical current, wherein the respective baseline electrical current is associated with a test pattern image displayed while determining the respective value of total electrical current; determining, based on the plurality of electrical current value differences and the different respective intensity values of each respective pixel of the at least three pixels, a plurality of pixel aging characterization values, each pixel aging characterization value within the a plurality of pixel aging characterization values indicating a respective decrease in electrical current consumed by a corresponding respective pixel within the at least three pixels; and determining, based upon the plurality of pixel aging characterization values, a display aging compensation matrix representing values by which pixel intensity values for the at least three pixels are to be compensated.
