The PI-Scale OLED lighting open access pilot shows first flexible OLED panel demonstrators

PI-Scale made demonstrators on the S2S and R2R process flows of the pilot lines up to 15 m long OLED-stripes with an efficiency higher than 30 lm/W and with nearly 100% yield

The European open access pilot line project PI-SCALE has produced their first demonstrators of flexible OLED out from this project. The demonstrators represent results from first pilot line production within the PI-SCALE project at the forthcoming IDW 23rd International Display Workshops in Fukuoka, Japan, from December 7– 9, 2016.

A key barrier to innovation in Europe is the lack of access to advanced, cost-intensive infrastructures and expertise needed to manufacture new and innovative products. A barrier that impacts thousands of high tech SMEs across Europe.

The European Pilot Line Initiative PI-SCALE is focusing on especially this gap – to help companies take photonic technologies from lab into market by creating a world-leading open access pilot line in Europe for the manufacturing and system-level integration of flexible OLEDs.

Flexible OLED lighting applications are supposed to open up a wide range of new possibilities for special lighting applications e.g. in medical applications for light therapy, in architecture, aircraft and railway as a lightweight opportunity, for various touch-display applications in automotive industry. Ideas for such applications and a lot of OLED products are already existing. Also, the latest research results and technological know-how is ready to be used.

In 2016 the PI-SCALE project started with the ambition to create a world-leading open access pilot line, based in Europe, for companies interested in the manufacture and system-level integration of flexible OLEDs into products. This will be achieved by bringing together the very best of the existing European infrastructure and know-how on flexible OLEDs from different locations into one pilot line. The pilot line service will enable companies of all sizes to quickly and cost effectively test and scale up their flexible OLED lighting or signage concepts and bring them to a level where they are ready to be transferred to a mass production facility.

Fraunhofer FEP, has extensive and long lasting expertise and know-how in operation of its R&D lines for manufacturing of OLED lighting devices. As one of the core team partners within, is responsible for the R2R anode deposition on barrier web, which is produced by the project partner Holst Centre as well as for the OLED-deposition by using evaporation processes. The OLED-deposition at Fraunhofer FEP can be done in Roll-to-Roll (R2R) and Sheet-to-Sheet (S2S) processes. In R2R it is possible to produce endless long stripes with up to 30 lm/W and in S2S high quality OLEDs with a high performance can be produced. As substrates the pilot line mainly uses plastic web and ultra-thin-glass.

According to the announcement:

  • Around 50m of OLED were deposited in the R2R process
  • These panels have an average efficiency of 30 lm/W

To show the reliability and reproducibility of the pilot line it is planned:

  • to produce 15m long OLEDs on R2R each month and to evaluate them
  • to produce batch of four 6-inch plates, on S2S each month, to demonstrate the operational capability of the pilot line production processes

In order to achieve this and to validate the functionality of the pilot line service:

  • partners across the whole value chain are represented in PI-SCALE – from material supplier up to the end user
  • Together with the other technology partners of the pilot line customer specific OLED solutions are offered considering also the price-performance ratio

The pilot line service will be ready to supply customers with unique customised flexible OLEDs on thin-glass as well as on plastic foil, which can be produced in R2R and S2S - from July 2017

Project leader Claudia Keibler from Fraunhofer FEP, said, "We could demonstrate that the S2S and R2R process flows of the pilot line are working by producing up to 15 m long OLED-stripes with an efficiency higher than 30 lm/W and with nearly 100% yield."

This project is funded by the European Union’s Horizon 2020 research and innovation program under grant agreement No. 688093.

About Fraunhofer FEP

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP works on innovative solutions in the fields of vacuum coating, surface treatment as well as organic semiconductors. The core competences electron beam technology, sputtering and plasma-activated deposition, high-rate PECVD as well as technologies for the organic electronics and IC/system design provide a basis for these activities.

Thus, Fraunhofer FEP offers a wide range of possibilities for research, development and pilot production, especially for the processing, sterilization, structuring and refining of surfaces as well as OLED microdisplays, organic and inorganic sensors, optical filters and flexible OLED lighting.

Our aim is to seize the innovation potential of the electron beam, plasma technology and organic electronics for new production processes and devices and to make it available for our customers. COMEDD (Center for Organics, Materials and Electronic Devices Dresden) with all known activities in organic electronics is now acting as a new business unit at Fraunhofer FEP, Dresden, Germany.

About PI-Scale (Eu project)

PI-SCALE, PIX4LIFE, and MIRPHAB, three major Pilot Lines, which help companies take photonics technologies from lab into market, have been launched by the Photonics Public Private Partnership (PPP).

The Pilot Lines mean that companies will be able to take their good ideas, scale-them up and validate them with the first customers for commercial production. This includes the thousands of high tech SMEs in Europe who often lack access to advanced, cost-intensive infrastructures and expertise needed to manufacture new and innovative products.

The Pilot Lines will focus on health applications, flexible organic light-emitting diodes and sensors for the detection of chemicals in gas and liquids. The European Commission has invested €35 million in these projects to boost Europe’s industrial competitiveness. This is part of the Commission’s €700 million investment in the Photonics Public Private Partnership over the seven years of Horizon 2020, the Framework Programme for Research and Innovation.
