The MicroLED Industry Association (MIA), a cross-industry association created to accelerate the adoption of microLED display technologies and facilitate collaborations between companies in the MicroLED industry, is proud to announce The MicroLED Library.

This new platform is an extensive compilation of MicroLED datasheets, presentations, whitepapers and more. To date, it already curates content from various companies (including GE, Terecircuits, Radiant Vision Systems, CEA-Leti and more), some of which is available in several languages, and includes the MIA's own whitepapers. The MicroLED Library is public and free for everyone to use. It will be continuously updated in order to remain a valuable resource for MicroLED information. You can access it here!

OLED is an amazing technology for lighting - it creates beautiful, efficient and healthy light sources. OLED lighting has great promise but unfortunately the high price of production is a challenge that no one has managed to overcome and OLED lighting remains a small niche industry as of 2019.

In the early years, several large lighting makers (including GE, Philips, OSRAM, Panasonic, NEC and others) had active OLED lighting programs, but slowly almost all of these companies dropped out of the market - for various reasons - but the main one being that the large investments in large scale production are not certified to lead to market adoption and the competition with LED lighting is extremely difficult.

Konica Minolta will unveil new flexible OLED lighting panels at the Lighting Fair 2013 exhibition in Tokyo next month (March 5). Their flexible OLEDs will debut in a "variety of forms", and visitors to KM's booth will be able to experience those new panels. 

We do not have any more information yet - hopefully KM will give technical details soon (or during the exhibition). Back in 2010 KM (together with GE) unveiled flexible OLED panel prototypes, but it seems that now the company is set to actually releasing products. The 2010 prototypes achieved 56 lm/W (and "commercially viable lifetime") using soluble materials in a roll-to-roll process. In 2010 the companies announced plans to produce those panels in 2011, but obviously this never happened. We're not sure if GE is involved in these new panels.

Nanomarkets posted an interesting article discussing what a low-growth world means for OLED lighting. They say that while OLEDs has been touted as a high-efficiency lighting technology, this feature alone will not be enough to gain real market share in the lighting industry as the developed world is experience difficult financial times.

There are still technology challenges that needs to be overcome, and companies need to commit to mass production before OLED lighting will begin to sale in meaningful quantities. Nanomarkets also laments the lack of industry leadership - they hoped that GE will be the leader, but it seems that their solution-processable OLED approach is not advancing as everybody hoped, and other companies aren't talking about mass production yet. It seems clear that it'll take at least 3-4 years for the OLED lighting market to actually emerge.

Update: The video is now marked as private...

GE has produced a beautiful short video ad showing the history of light, ending with OLEDs, the next chapter of light. Unfortunately, that video is now marked as "private" and is no longer accessible...

Back in February, Pioneer and Mitsubishi Chemical has announced an OLED Lighting JV. Pioneer will produce OLED lighting panels, Mitsubishi Chemical will supply chemicals and will market and sell the panels through their Verbatim daughter company.

We had the good chance to speak with Verbatim regarding this new OLED business.

Q: Are there any updates on the OLED JV?
Mitsubishi Chemical Corp will start to supply samples at the end of 2010, and mass production in the middle of 2011.

OLEDNet reports the Konica-Minolta plans to start mass production of flexible OLED lighting panels in 2010. Konica-Minolta is cooperating with GE on manufacturing technology. According to the report, Konica Minolta is using polymer materials and printing technologies. The materials are made by Sumitomo. The lifetime of Konica-Minolta’s products is estimated to be 3,000 hours or more with the brightness of 1,000 cd/m2.

We think that this is a bit optimistic... according to KM's own plans, the first plant is scheduled for March 2011. Just last month they re-iterated their plans to start making the flexible OLEDs in 2011, and we do not think this will qualify as 'mass production'. We also know that KM is using UDC's Small-Molecule Phosphorescent materials, but maybe they are also working with Sumitomo on Polymer based OLEDs.

GE and Konica Minolta announced that they have achieved a "major breakthrough" in their white OLEDs: an efficient 56Lm/w flexible white OLED that is made using solution-coatable materials in a roll-to-roll printing process. The materials have "commercially viable lifetime" (we do not know exactly what they mean by that).

GE and Konica Minolta flexible desk lamp prototype

GE and Konica Minolta plan to introduce their flexible OLED lighting products next year (2011), and have already displayed some early prototype lamps (one of which is shown above). They are working together since 2007. KM hopes to see $1 billion in OLED Lighting sales by 2018. KM has licensed OLED IP from UDC.

GE and Konica Minolta is showing new lamps which use flexible white OLEDs. There are several "configurations" (or designs, really) which include desk lamps and ceiling lamps.We do not have any technical details on those panels yet.

We already know that GE plans to start printing OLED Lighting panels in 2010. Now Anil Duggal, GE's OLED lighting printing group leader, says that they know that those pilot panels will be very expensive. He hopes that by 2015, it'll be possible to print OLED panels that will be both cheap and efficient.

GE has recently received $4 million from the DOE to upgrade their pre-pilot roll-to-roll manufacturing lines (the whole project will require $8 million).
