The Fraunhofer Institute for Applied Polymer Research (IAP) develops bio-based and synthetic polymers, from the laboratory to the industrial scale. Applications are diverse across many markets, such as bio-based packaging, lightweight materials, truck tires and more.
One of the applications being researched and developed at the Fraunhofer IAP is luminescent materials for displays. The IAP functional polymer systems division, looks into a broad range of materials, including light-emitting polymers and quantum dots. The focus lies in solution processing of these materials with a strong focus on printing methods.
The latest Fraunhofer OLED news:
An AILU (Association of Industrial Laser Users) webinar, scheduled for September 15, will introduce the basics of OLED lighting, discuss the choice for the right substrate and encapsulation material as well as the current status of roll-to-roll processing. The webinar is sponsored by 3D Micromac, the industry leader in laser micromachining and roll-to-roll laser systems.
The webinar will also show results from the EU-funded LAOLA project, which is a collaboration between German and Japanese companies and research institutes. The LAOLA project, led by the Fraunhofer FEP, develops the use of ultra-thin flexible glass as a substrate and encapsulation material in roll-to-roll technology for this purpose.
The Fraunhofer FEP Institute published this nice video that shows its latest technology innovations, including its OLED (regular and bi-directional) microdisplays, its new AR/VR optics, flexible OLED lighting panels, its Monarch flexible and transparent OLED panels, sensor and coating technologies and more.
The Fraunhofer FEP also created and published a new virtual tour of its facilities, where you can have a look inside the labs and flexible organic electronics R&D clearnroom.
Notion Systems, MBraun and the Fraunhofer IAP develop a novel display industrial production process based on inkjet printing
Notion Systems, MBraun and the Fraunhofer Institute for Applied Polymer Research (Fraunhofer IAP) are co-developing new inkjet production technologies, aimed for the display market - specifically for OLED, QD and microdisplays.
The three partners are combining their respective competencies to present themselves together as a partnership supplier off all-in-one solutions. The Fraunhofer IAP is developing custom-made processes for display manufacturing with tailor-made inks. To achieve an industrial-scale best-in-class process solution, the parties are looking into all major pre-and post-processing steps, the substrate and the production equipment such as the inkjet print head.
Researchers from Semiconductor Energy Laboratory (SEL) developed flexible OLED displays that incorporate organic image sensors inside the OLED pixels using side-by-side patterning. The sensors can be used as cameras for applications such as fingerprint sensing - which will work on the entire display.
SEL presented two prototypes, one a 3.07" 360x540 (212 PPI) display and the second is a 8" one with a higher pixel density of 302 PPI. SEL says that the fingerprint recognition works even when the display is bent.
The Fraunhofer first demonstrated its bi-directional OLED microdisplays in 2009 - these display use photodetectors embedded between the OLED pixels to enable unique applications such as eye-tracking and more.
The Fraunhofer now suggests a new use for such displays. The BiClean project looked into the possibility of embedding bi-directional OLED microdisplays in solar panels or pipes, to detect contamination in early stages. The display project light at different colors, and the photodetectors can sense the surface status in real time - and so it is possible to know whether it is necessary to clean the surface.
In 2018 the Fraunhofer FEP institute announced it is starting to offer a design kit that includes several flexible and transparent OLED lighting panels. The Monarch Kit includes several colored butterflies samples, and the researchers were kind enough to send us one such kit for a short review.
So first of all, these OLEDs look beautiful. They shine a beautiful uniform colored light and are very nicely done. There's not much functionality, but it shows the potential of flexible OLED lighting quite nicely.
A few days ago the Fraunhofer FEP institute announced that it developed OLED light strips made from tiled flexible OLED lighting panels, and now we have these nice looking strips on video:
The video was taken at Fraunhofer FEP's booth at the International Symposium on Automotive Lighting 2019 in Darmstadt, Germany. The strips, produced in a sheet-to-sheet process can be connected without creating visible interruptions to the active surface. This makes it possible to produce infinitely long OLED light strips. Each segment can be controlled individually - so that different dimming or dynamic signalling can be achieved.
The Fraunhofer FEP institute developed OLED light strips made from tiled flexible OLED lighting panels. The new strips can be produced in any length and will be on display next week at the International Symposium on Automotive Lighting 2019 in Darmstadt, Germany.
The Fraunhofer FEP produces the flexible OLED panels in a sheet-to-sheet process, and in such a way that they can be connected without creating visible interruptions to the active surface. This makes it possible to produce infinitely long OLED light strips. Each segment can be controlled individually - so that different dimming or dynamic signalling can be achieved.
In 2016 the EU launched the PI-SCALE project, which established a European-wide roll-to-roll flexible OLED lighting pilot production line, with an aim to enable companies of all sizes to quickly and cost effectively test and scale up their flexible OLED lighting concepts. In 2018 the EU has launched a €14 million initiative within PI-SCALE called LYTEUS, which provides the expertise and capability required to progress an OLED lighting concept from an idea and into a commercialized product.
The PI-SCALE project has successfully been completed, and the Fruanhofer FEP institute now announced that following a meeting with the EU Commission representatives, it was decided that the OLED lighting pilot line services will continue to be funded, under the lead of the Fraunhofer FEP. The pilot line service will continue under the name LYTEUS.
The Fraunhofer FEP announced that it has developed a new OLED Microdisplay specifically for industrial Augmented Reality (AR) data glasses.
The new microdisplay features a 720p (1280x720) resolution with a diagonal size of 0.64-inch (subpixel size is 5.5 micron). The power consumption is 160 milliwatt at 120 fps. The Fraunhofer says that the new display features simple driving electronics for an easy integration into portable systems and is already available as evaluation kit.
