Plastic Logic and ISORG Partner on Flexible Image Sensor

Plastic Logic and ISORG join forces to commercialize flexible image sensors. The collaboration is based on the deposition of organic printed photodetectors (OPD) by ISORG, onto a plastic organic thin-film transistor (OTFT) backplane, developed by Plastic Logic, to create a flexible sensor with a 4x4 cm active area, 375um pitch (175um pixel size with 200um spacing) and 94 x 95 = 8 930 pixel resolution.

The backplane design, production process and materials were optimized for the application by Plastic Logic to meet ISORG's requirements. Combined with ISORG's unique organic photodetector technology, it opens up the possibilities for a range of new applications, based around digital image sensing, including smart packaging and sensors for medical equipmen tand biomedical diagnostics, security and mobile commerce (user identification by fingerprint scanning), environmental, industrial, scanning surfaces and 3D interactive user interfaces forconsumer electronics (printers, smartphones, tablets, etc.).

ISORG's CEO, Jean-Yves Gomez stated: "We are extremely pleased to showcase our disruptive photodiode technology in a concrete application for imaging sensing. The ability to create conformal and large area image sensors, which are also thinner, lighter and more robust and portable than current equipment is of increasing importance, especially in the medical, industrial and security control sectors."

Indro Mukerjee, CEO Plastic Logic said: "I am delighted that Plastic Logic can now demonstrate the far-reaching potential of the underlying technology. Our ability to create flexible, transmissive backplanes has led us not only to co-develop a flexible image sensor,but is also key to flexible OLED displays as well as unbreakable LCDs."


  1. Is this technology OK for small size pixels associated with CMOS circuits?? Thanks!

  2. Has anyone seen anything about the performance or projected cost of these sensors? I'm not seeing anything online and wondering how they compare to current wafer-based sensors.

  3. This is for large size sensor.

  4. What can we do with 175um pixel size with 200µm spacing? (equivalent to pixel of 375µm with 20% of fillfactor ...). Everybody in the field knows that high fillfactor is required in medical Imaging to ensure reliable diagnostics.

    1. right! In addition, pixel size is almost 3-5 times larger than what is required for medical and 5x larger than needed for fingerprint authentication. It seems at least 5-6 additional years would be required to develop a first prototype effectively addressing these markets.

  5. Does it means that the transistor is 200µm x 200µm? In that case, sounds hard to downsize the pixel design for any real applications at short term...
