In this paper, a proof of concept 4 x 4 active-matrix imager fabricated at near room temperature (< 95 degC) is presented. Conventional
photolithography and inkjet printing were used to pattern integrated
organic FETs and photoconductors. The design and characterization of a
pixel circuit is described. A simple first-order calibration technique is
used to partially compensate for fixed pattern noise. Following the
calibration, the imager is shown to correctly image a "T" pattern.
