At SID, we reported on the development of OLEDs on stainless steel substrates by the Fraunhofer FEP in cooperation with Nippon Steel & Sumikin Materials Co., Ltd. (NSMAT) and Nippon Steel & Sumitomo Metal Corporation (NSSMC). The group is to show the technology at the aimcal 2017 show in Tampa, USA from October 15th to 18th.
Jun Nakatsuka, Manager of Business Development at NSMAT said:
“Thanks to the smoothness and high thermal conductivity of the stainless steel foil we obtain extremely homogenous OLED light. We see OLEDs on stainless steel in perhaps three years from now being used in automobiles as turn indicator and back-up lights, as cladding for fascia, and as advertising displays.”
Michael Stanel, Project Manager within the R2R Organic Technology department at Fraunhofer FEP said
“In addition to machinery design and construction, we also possess comprehensive know-how in handling sensitive substrates. To be certain the stainless steel is suitable for the nanometer-thick organic layers, an R2R-compatible smoothing planarization layer was developed that is easy to integrate into the process.”
