DuPont developed new screen-printable nano-silver conductor ink that can be used to make grids and bus lines for OLED lighting panels. DuPont says that these materials are less expensive compared to materials currently used for such panels, and they offer a simpler manufacturing process.
DuPont estimates that these new inks will be commercially available next year. The inks provide extremely high conductivity and excellent adhesion even after substrate cleaning steps. They can be used on glass and flexible polymer substrates such as DuPont's own Kapton polyimide films and polyethylene naphthalate (PEN).
DuPoint is already developing the second-generation of these inks, and these will be suitable for flexible OLED lighting panels produced on lower cost substrates such as polyethylene terephthalate (PET).
