Digitimes: RiTdisplay starts to produce OLED lighting panels

According to Digitimes, PMOLED display maker RiTdisplay has started to produce flexible OLED lighting panels, targeting the automotive, medical and consumer (home) applications.

For the automotive market, the RiTdisplay is apparently collaborating with Luminit, through its Taiwan-subsidiary Luminit Automotive Technology. RiTdisplay is holding 30% at LAT which is already starting to supply OLED lighting panels for automotive brake lights and started low-volume shipments in Q1 2019.

Lyteus partners demonstrate the world's longest flexible OLED lighting device at 15 meters

The Fraunhofer FEP institute, the Holst Center and other partners have developed a 15-meter long OLED lighting panel, the longer OLED device ever (beating their own 2017 record of a 10-meter OLED). This work was done as part of the Lyteus, the EU's €14 million initiative within PI-SCALE.

The partners in this project say that this is the first OLED produced using a new unique roll-to-roll (R2R) process that combines the performance of an evaporated OLED stack with solution processing of auxiliary layers.

The Fraunhofer FEP develops a new technology to produce ultra-smooth polymer films

The Fraunhofer FEP announced that it developed a new technology to produce ultra-smooth polymer films. The new technology can be used to produce low-defect density films in a roll-to-roll based process, suitable for a wide range of applications - including encapsulation films, touch layers and as OLED substrates.

This technology was developed as part of the EU-funded OptiPerm project. The Fraunhofer researchers say that this new innovative process does not require any special processing environment and could be used under standard factory conditions.

The EU launches Lyteus, a €14 million initiative to support PI-SCALE OLED lighting projects

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.

Now 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. Lyteus helps companies with sheet-to-sheet and roll-to-roll prototyping of flexible OLEDs, technology transfer, device encapsulation and more. At launch Lyteus serves four customers: Audi, Rehau, Emde and Pilkington, to develop flexible OLED lighting products in the automotive, aeronautics and designer luminaires sectors.

ITRI expands its pilot R2R flexible OLED lighting line

Taiwan's ITRI institute says that recent advances in OLED materials and production methods has enabled it to greatly reduce OLED lighting production costs. Recent technical achievements at ITRI include a new flexible substrate transfer, R2R production process integration, and soft light source system design.

In 2016 ITRI constructed a pilot roll-to-roll production line for flexible OLEDs. ITRI now says that these technical achievements will enable it to increase the production line capacity for 50,000 monthly panels. ITRI also developed a new flexible OLED that weighs only 10.7 grams and is less than 0.5 mm thick.

The EU SOLEDLIGHT project developed solution-processed R2R OLEDs, reports interim results

The SOLEDLIGHT (Solution Processed OLEDs for Lighting) project was launched in 2015 by a European consortium with an aim to develop cost efficient, roll-to roll (R2R) solution processed OLEDs, including their integration in prototype multiple-panel OLED lighting systems and luminaires.

The SOLEDLIGHT consortium (which is coordinated by the University of Valencia and includes OSRAM and Solvay) reported that it managed to develop multi-layer R2R solution processed OLEDs that achieved a power efficiency of 20 lm/W. This is still not up to par with evaporation-based OLEDs, but the project partners aim to achieve 100 lm/W (and 15,000 hours) by the end of 2017.

The Fraunhofer FEP, NSMAT and MSSMC developed an OLED on a stainless steel substrate

The Fraunhofer FEP institute, in collaboration with Nippon Steel & Sumikin Materials (NSMAT) and Nippon Steel & Sumitomo Metal Corporation (NSSMC), developed a new OLED lighting prototype that is made on a stainless steel substrate.

The researchers say that a stainless steel substrate has several advantages compared to glass or plastic - it has excellent thermal conductivity and excellent barrier properties. The lighting panel features an extremely homogenous OLED light, thanks to the planarization layer developed by NSSMC. The prototype panel was produced at the Fraunhofer's R2R research line.

EU's PI-SCALE project can now produce 10 meter long OLED Lighting panels

In March 2016 the EU launched a new project, called PI-SCALE, that aims to create a European-wide pilot line which will enable companies of all sizes to quickly and cost effectively test and scale up their flexible OLED lighting concepts and turn them into market ready products.

PI-SCALE members started to produce sample panels - and can currently make long films up to 10 meters in size. You can see such sheets (cut to 1.8 meters) in the video above, taken at SID DisplayWeek.

The FlexE Center in Kanpur orders a bespoke pilot R2R line for printed and flexible electronics R&D

The National Centre of Flexible Electronics (FlexE Centre) at the Indian Institute of Technology in Kanpur announced that it assigned UK-based RK PrintCoat Instruments to manufacture and supply a bespoke roll-to-roll (R2R) pilot line that will be used for R&D and prototyping projects in the field of printed and flexible electronics.

The National Centre for Flexible Electronics (FlexE) was established in 2014 at the Indian Institute of Technology in Kanpur, with an aim to bring together Indian academia, industry and public research organizations for research and development of large area flexible electronics. The FlexE center develops OLED lighting and OLED signage applications and is collaborating with industrial partners in both fields. The center explores evaporation, printing and hybrid processing for OLED production.
