15-meter roll-to-roll device is world’s longest OLED

29.11.2018

Working within the framework of Lyteus, Holst Centre and Fraunhofer FEP step into the spotlight with the creation of the world’s longest single-device OLED. At a stunning 15 meters in length it opens the door to ‘endless OLEDs’ that manufacturers and designers can then easily tailor to their own needs.

Lyteus brings together leaders in OLED technology from across Europe to create a pilot production line and product development services for OLED products.

Working together, Holst Centre and Fraunhofer FEP successfully demonstrated the possibility for continuous production of OLEDs of any length. This both reduces the cost of production and enables “cut-to-fit” lighting for applications such as transportation, architecture and interior design.

“This is a major milestone in the development of pilot line Roll-to-roll (R2R) technologies that will enable Lyteus to offer long OLED strips to its customers. It is an example of how the Lyteus pilot line turns flexible OLED possibilities into products. It was only possible due to the unique capabilities of Holst Centre and Fraunhofer FEP and the great cooperation between them and other Lyteus partners” says Pavel Kudlacek, leader of Technology Development at Lyteus.

Unique OLED structure

It is the first OLED source produced using a unique R2R process that combines the performance of an evaporated OLED stack with solution processing of auxiliary layers. Moreover, the combination improves the process reliability and enables fabrication of devices of any length.

To produce the device, Fraunhofer FEP deposited an indium-tin oxide (ITO) anode onto a protective multi-layer barrier film produced by Holst Centre. The roll was processed at Holst Centre, where slot-die coating was used to structure the anode and deposit the first layer of the OLED stack.

Fraunhofer FEP then evaporated the rest of the OLED layers and finalized the devices by lamination of Holst Centre barrier. The resulting devices have a good homogeneity and an efficacy of 15 lm/W at a light output of 1000 cd/m2.

“Roll-to-roll production promises higher volumes and lower costs for flexible electronics applications like OLEDs. At Holst Centre we have been developing a unique solution coating roll-to-roll line for 10 years. The 15-meter OLED shows that the technology is now ready for industrialization, and can deliver cost-effective, high-volume OLED production,” says Pim Groen, Program Manager at Holst Centre.

“The 15-meter OLED is further evidence of our ability to deposit high-quality organic layers and integrate them with solution-processed layers to create reliable and homogeneous devices in a continuous process. It is a step towards the creation of ‘endless’ OLED devices and a further step in our R2R OLED manufacturing processes, which we are developing now for more than 10 years,” says Jacqueline Hauptmann, Project Manager OLED R2R at Fraunhofer FEP.

About Lyteus

Lyteus offers world class capability and services in the pilot production of customised flexible OLEDs and is focusing on product streams in the areas of automotive, designer luminaires and aeronautics applications. Lyteus is a spin off from the EU-project PI-SCALE and is a cooperation between Holst Centre, Fraunhofer FEP, VTT and CPI. PI-SCALE brought together fourteen expert partners from five European countries and includes Holst Centre, Fraunhofer FEP, Centre for Process Innovation (CPI), VTT, AUDI AG, REHAU, emde development of light, Pilkington, M-Solv, FlexEnable, DuPont Teijin Films, Coatema Coating Machinery and AMIRES. PI-SCALE is an initiative of the Photonics Public Private Partnership co-funded by the European Union’s Horizon 2020 Research and Innovation Program under Grant Agreement No 688093 with a contribution of €14 million.

About Holst Centre

Established in 2005 by imec and TNO, Holst Centre is an independent R&D center that develops technologies for next-generation electronics systems. These include, but are not limited to, wireless autonomous sensors and electronic systems-in-foil that are flexible, stretchable and 3D formable. These are key building blocks for Internet of Things, mobile healthcare and smart surfaces and structures. Holst Centre bridges the gap between industry and academia by advancing technologies from lab to fab, based on robust roadmaps and programs. To facilitate this, Holst Centre establishes and creates open innovation programs involving a wide ecosystem of partners and participates in dedicated projects with industrial customers.

About Fraunhofer FEP

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, plasma-activated deposition and 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.

Im Focus: Fraunhofer IDMT demonstrates its method for acoustic quality inspection at »Sensor+Test 2019« in Nürnberg

From June 25th to 27th 2019, the Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau (Germany) will be presenting a new solution for acoustic quality inspection allowing contact-free, non-destructive testing of manufactured parts and components. The method which has reached Technology Readiness Level 6 already, is currently being successfully tested in practical use together with a number of industrial partners.

Im Focus: Successfully Tested in Praxis: Bidirectional Sensor Technology Optimizes Laser Material Deposition

The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.

Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...

Im Focus: MPSD team discovers light-induced ferroelectricity in strontium titanate

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.

Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
