1. An image sensor array comprised of a plurality of high dynamic range sensors disposed as matrix addressable pixel elements each associated with a gate line, a data line and a bias voltage line,wherein each of the pixel elements comprises an amorphous silicon sensor segregated into a plurality of discrete sensor portions, each portion having a distinctive responsiveness to incident illumination, wherein the portions are in common communication with the data line for generating a summed charge output representative of the illumination;

  • and,read-out electronics for selectively addressing the data line and generating an electrical signal representative of the illumination.
