ISORG to demonstrate working thin-film plastic image sensor
ISORG will demonstrate a working plastic image sensor at Printed Electronics USA this week in Santa Clara. The device was developed in collaboration with Plastic Logic, combining ISORG's organic photodetectors (OPD) with Plastic Logic's organic thin-film transistor (OTFT) backplane.

In the past, OTFT backplanes have been used to make flexible displays for e-readers, but the technology can now be applied to perform pixel readout in a large area image sensor.

At the show, the companies will demonstrate image scanning with a plastic image sensor with an active area measuring 40x40mm and featuring 96x96 pixels (over 9,000 pixels with a 375um pitch), a world’s first according to Laurent Jamet, Co-Founder and Director of Business Development at ISORG.

"ISORG and Plastic Logic worked jointly to combine their two technologies of organic photodetector and organic thin film transistor, defining the right interconnection solutions", Jamet explained.

The demonstration will show how the famous Mona Lisa portrait can be scanned without a photographic lens, by placing the picture directly on the large area sensor. Visitors will also be invited to create their own images.

Although the proof-of-concept device has a relatively low resolution, it demonstrates how two printed electronics components can be combined to create new products. ISORG and Plastic Logic are now working on reducing the pixel pitch.
