70‐2: Sheet‐type Image Sensor with Near Infrared Sensitive Organic Photodiode

Abstract

We have developed an ultra‐flexible organic photodetector with high sensitivity in near infrared regions. The photodetector exhibits good mechanical durability. The change in dark and photocurrent was approximately 10% after 500 cycles at a bending radius of 1.6 cm. Furthermore, the photodetector also shows good air stability. By combining the organic photodetector and low‐temperature polycrystalline silicon thin‐film transistor backplane, we developed a conformable imager with a high resolution of 508 dpi.
