The Organic Electronics Association (OE-A), an organic electronics industry group for European companies, exhibited electronic devices manufactured with printing technologies at Printable Electronics 2009.

Visitors of the exhibition, which took place from Feb 18 to 20, 2009, at Tokyo Big Site, could pick up and see the devices.

The electronic devices exhibited in the OE-A's booth were all developed by companies belonging to the association. They include memory developed by Thin Film Electronics ASA, a TFT substrate by BASF SE, an RFID tag by PolyIC, organic wiring by HC Starck Ltd and an RFID antenna by COPACO SA.

Thin Film Electronics' memory is nonvolatile RAM with a capacity of 1,024 bits. It is intended for use in ID cards and game cards.

BASF's TFT substrate incorporates an inverter circuit formed by TFTs. It was manufactured by using various printing technologies, including offset printing for the source and drain, gravure printing for the semiconductor layer and flexo printing for the gate insulation film and gate electrodes.

PolyIC's RFID tag supports a frequency of 13.56MHz, and its circuit is composed of printed TFTs. It is equipped with a general metallic antenna, according to the company. The product is intended for the prevention of counterfeiting as well as for use as tags for logistics.

Furthermore, OE-A showcased a circuit used for the electronic devices. It is equipped with an organic TFT circuit, a flexible battery and an OLED panel.
