1. A method of addressing an array of spatial light modulator elements, comprising the steps of:

  • dividing the array into blocks of elements;

    providing reset lines to each of the blocks of elements, separate from the other blocks of elements;

    providing address voltage supplies to each of the blocks of elements, separate from the other blocks of elements;

    sending address data to each of the blocks independent of sending address data to the other blocks;

    resetting each of the blocks to respond to the address data independent of the other blocks; and

    stepping address voltage to each of the blocks of elements, such that only the blocks of elements that are being reset receive the stepped address voltage.
