World’s first conformable, organic image sensor on plastic

11 June 2013

A sensor, developed by Isorg and Plastic Logic has the potential to revolutionise vision systems with weight/power trade offs.

The collaboration is based on the deposition of organic printed photodetectors (OPD), pioneered by Isorg, onto a plastic OTFT (organic thin-film transistor) backplane, developed by Plastic Logic, to create a flexible sensor with a 40x40mm active area. It has a 375µm pitch (175µm pixel size with 200um spacing) and 94x95, 8930 pixel resolution.

According to the company, the flexible, transmissive backplane represents a breakthrough in the manufacture of large area image sensors and demonstrates the potential use of the flexible transistor technology to move beyond plastic displays.

The organic photodetector technology could mean new applications, based around digital image sensing, including smart packaging and sensors for medical equipment and biomedical diagnostics, security and mobile commerce (user identification by fingerprint scanning),environmental, industrial, scanning surfaces and 3D interactive user interfaces for consumer electronics (printers, smartphones, tablets). The conformal, large area image sensors are thinner, lighter and more robust and portable than equipment currently available in these markets.

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.”

First mechanical samples will be unveiled at LOPE-C 2013 in Munich, Germany this week.
