Active-Matrix IGZO Array with Printed Thermistor for Large-Area Thermal Imaging

Title:
Active-Matrix IGZO Array with Printed Thermistor for Large-Area Thermal Imaging

Abstract:
We present a 16×16 active-matrix IGZO array integrated with a screen printed thermistor on a thin and flexible substrate. Screen printing of the thermistor together with a flat-panel compatible backplane technology provides a cost effective and scalable route to large area thermal imaging. We show that by integration on thin polyimide film the thermal time constant improves by a factor of 30 compared to the same thermistor array on glass. In addition, we show that the thermal response can be further improved by reducing the thickness of (mainly) the printed thermistor layer.
