DuPont shares new research on OLED lighting

DuPont Microcircuit Materials (DuPont) will present initial research findings about new screen printable nano-silver conductor ink developments for grids and bus lines in Organic Light Emitting Diode (OLED) lighting and other printed electronics applications at the ID Tech-Ex Printed Electronics Europe Conference in Berlin, Germany, from April 1-2. DuPont anticipates that, once commercialized, the new conductor materials will help enable a simpler OLED manufacturing process and provide less expensive alternatives to materials currently used, consistent with the business' aim to expand its suite of advanced materials for printed electronics.
"We believe that advanced technology like our promising new nano-silver conductor ink developments will help enable progress in high value, rapidly growing technologies like OLED lighting," said Kerry Adams, European marketing manager, DuPont Microcircuit Materials. "We are very excited to share our research findings and gather important feedback from industry leaders as we continue our development efforts toward commercial products."
DuPont anticipates that new nano-silver conductor ink materials, will be commercially available next year and that these materials will be able to provide a combination of extremely high conductivity and excellent adhesion even after substrate cleaning steps. In addition it is expected that these new inks would help enable the combination of low print thickness and smooth sintered surface necessary for OLED and optoelectronic applications where deposition of subsequent layers is required. The anticipated products are currently intended for use on glass and higher performance flexible polymer substrates such as DuPont™ Kapton® polyimide films and polyethylene naphthalate (PEN). However, it is expected that second generation versions in development would be suitable for flexible OLED lighting panels constructed on lower cost substrates such as polyethylene terephthalate (PET).
Research findings will be presented by Dave Hui, product development scientist, DuPont Microcircuit Materials, on April 2 as part of the conference session titled, "Nano-Ag Conductors for OLEDs and other Printed Electronics Applications."
DuPont also will exhibit at stand C02 its broad and growing array of materials for printed electronics applications including its recently expanded suite of low silver, conductive inks specifically tailored for membrane touch switch (MTS), radio-frequency identification (RFID), and wearable electronic applications. Designed to balance conductivity needs with cost concerns, the DuPont PE8XX materials leverage proprietary DuPont technology in order to deliver higher conductivity from precious metals.
