1. A method of real-time calibration for a display array having a plurality of pixel circuits arranged in rows and columns, the method comprising:

  • generating a priority list of pixels;

    associating calibration priorities with a plurality of pixel circuits from the pixel circuits of the display array;

    selecting one or more pixels (n) from the priority list, the n selected pixels having the highest calibration priorities of a set of pixels in the priority list;

    programming each of the n selected pixels with a respective driving voltage;

    determining calibration information for each of the n selected pixels based on their respective driving voltages;

    updating a compensation voltage of the n selected pixels stored in a memory based on the determined calibration information; and

    responsive to updating the compensation voltage, updating the priority list.
