AGFA and so on the use of transparent resin electrode trial bending OLED lighting

Belgium AGFA-Gevaert NV, Holland PHILPS Research Institute (Philips Research), Holland Holst Centre, IMEC of Belgium and Holland TNO announced that the trial out of the 12cm square flexible OLED lighting panel with high conductive transparent resin electrode instead of ITO. It is difficult to ensure the conductivity of ITO at low temperature. And the use of transparent resin conductive, and suitable for coating method, so easy to use printing process. The results were achieved with the help of the EU project "Fast2Light" with the aim of creating flexible OLED lighting using a printing process.

The transparent resin is AGFA as a special anti-static film material and developed "Orgacon". The OLED component can also be used as a conductive resin based on PEDOT/PSS. SANYO motor and Tokyo Institutet of Technology are also actively developing this material.

The transparent electrode of the general OLED lighting panel is mostly the structure of laminated ITO films and PEDOT/PSS films. This time, by replacing the Orgacon with ITO, "the conductivity of the transparent electrode increased by about 6 times" (AGFA). But the specific conductivity is not disclosed.

The made of OLED lighting panel to improve the proportion of the printing process, such as the use of transparent electrode on the wiring pattern made of ink-jet printing, etc.. The bottom plate is made of metal foil and can be bent freely. Brightness and luminescence lifetime are not disclosed.
