1. A method of compensating for spatially repeated patterns of structural non-uniformities in an array of solid state devices in a display panel, said method comprising:

  • generating at least one image based on the spatially repeated patterns of the structural non-uniformities of the display panel, each of the at least one images matching one or more of the spatially repeated patterns;

    displaying the at least one image in the panel;

    extracting the outputs of the spatially repeated patterns across the panel, for each area of the structural non-uniformities;

    quantifying the non-uniformities based on the values of the extracted outputs; and

    modifying input signals to the display panel to compensate for the non-uniformities.
