New white top-emitting OLED architecture achieves high efficiency and outstanding color quality
Dec 24th
Researchers from Dresden’s University of Technology (TU Dresden) developed new highly efficient white top-emitting OLED design that feature “outstanding” color quality, and is compatible with flexible OLEDs. In this new design a refractive index matched microlens film was laminated to the top-emitting OLED to form direct optical contact. This enabled the researchers to achieve a CRI of 93, CIE coordinates of (0.472, 0.430) and an emission from 410 to 750 nm that almost spans the complete visible spectrum (380 to 780 nm). The efficiency is up to 30 lm/W (on par with the latest record white OLEDs from Novaled and OSRAM ). The lamination of such an outcoupling structure should be fully roll-to-roll compatible and even allows to be used as an encapsulation film when water and oxygen barriers are added. read more

Fraunhofer to show a 30-cm wide roll-to-roll flexible OLED lighting panel
Oct 7th
The Fraunhofer IPMS are developing a roll-to-roll process to make flexible large area OLED lighting panels. Next week they will show a 30cm wide flexible OLED lighting panel on a metal foil, fabricated at COMEDD . In fact they say that this demonstrates that they developed all necessary process steps for a complete production of flexible OLEDs in a roll-to-roll tool: from the structuring of substrate up to the lamination of barrier foils.

The EU launches a €18 million Organic & Large Area Electronics funding competition
Sep 25th
The European Union launched a new initiative called OLAE+. They offer €18 million in collaborative R&D funding in the area of Organic & Large Area Electronics. OLEDA+ is a competition that is open for participants from Austria, Catalonia, Flanders, Germany, Israel, Poland, Sweden and the UK, and first proposals must be submitted by January 31st 2012. Possible applications for OLAE are rollable/flexible displays, large area efficient lighting, low cost solar cells, low-cost RFIDs and memories, flexible and environmental friendly batteries and more. read more

Universal Display shows new flexible OLED lighting prototype
May 18th
Universal Display shows new flexible OLED lighting panels at SID 2011. The new panels use the company’s solution-processable P2OLED materials and the new single-layer encapsulation technology . UDC says they are showing this prototype to demonstrate how flexible OLED lighting and display technologies are accelerating towards commercialization. The new prototype is pretty small

Samsung flexible and transparent AMOLEDs at CES 2011
Jan 6th
A few days ago Samsung announced that they will show flexible and transparent OLEDs at CES. We assumed that these will be the same displays shown at the FPD 2010 exhibition (in November 2010) , and we were right. But still check out this great video of the 4.5″ flexible displays: read more
Samsung to exhibit flexible and transparent AMOLEDs at CES 2011
Dec 31st
Samsung announced that it will be showing flexible and transparent OLED displays during CES , but it seems that those displays aren’t new. The first display is a 4.5″ WVGA flexible AMOLED. This seems to be the same display shown at the FPD 2010 exhibition (November 2010) : The second display is a 19″ qFHD transparent (up to 30%) AMOLED for TVs and monitors, and also a 14″ qFHD transparent AMOLED for notebooks. This also seems to be the same displays shown at the FPD exhibition .

Applied Nanotech Exclucent: flexible, transparent substrates for OLEDs
Dec 1st
Applied Nanotech (ANI) is introducing Exclucent: flexible and transparent substrates on PET (polyethylene-terephthalate) that utilize copper-based metallic mesh. Exclucent substrates, which are offered as a replacement for ITO, are currently in volume production and are available to sell (ANI also offers specific application together with customers). Exclucent offers a sheet resistance lower than 0.1 Ohm/sq., which is tenfold lower than the best ITO coated substrates, according to ANI, and transparency better than 80% including the transparency of the substrate itself. ANI is currently developing methods to apply its copper ink product Cu-i70 to a variety of transparent substrates as a potential ITO coating replacement.

ITRI developed a 6" flexible color AMOLED
Oct 27th
Taiwas’s ITRI (Industrial Technology Research Institute) has developed a new 6″ flexible color AMOLED, using their FlexUPD technology. The display is just 0.01cm thick, and can continue to show images even when folded. The folding radius can reach 5cm or less, and the screen can be scrolled up to 15,000 times. ITRI says that their FlexUPD technology is the simplest and cheapest technology for mass production paper-like displays. FlexUPD will be commercialized soon, and AUO plans to use it for flexible e-reader products “very soon”. read more

Nemoptic unveils an OLED coupled with a Bistable Nematic LCD display
Oct 10th
Nemoptic has developed the world’s first display that combines a color OLED with a monochrome Bistable Nematic LCD (Binem). The idea is that you can choose whether you want to have an OLED displays, or a e-paper like display, depending on the application and lighting condition (this somewhat reminds us of Pixel-Qi displays ). A Binem display, which is patented by Nemoptic offers the optical performance of a normal Nematic display but is still retains the image even without any power (i.e. it is bistable, like e-paper ). Nemoptic displays are suitable for e-readers and other applications. Nemoptic claims that their displays offer a very high reflectance, a good contrast and good colors. They can also be made on flexible substrates – which means that the OLED/Binem display can probably be made flexible, too. read more

TAT shows the future of screen technology
Sep 12th
TAT (a Swedish software technology and design company) has produced a beautiful video showing the future of screen technology: flexible, stretchable displays, transparent screens, augmented UI and more. They do not mention OLEDs directly, but obviously these can fit right in. I’m not sure whether we’ll be able to cope with so much information all the time…
