The Holst Centre released a few nice videos, and I think they’re worth a watch. First up is the one about their flexible OLED display research. Last year Holst and imec announced a new program to develop high resolution flexible OLED displays , with a focus on a mechanically flexible encapsulation film and TFT backplane, printed high-efficiency OLED and new materials and processes. The video below shows their first display (which was already unveiled last month ): In this new video you can see that the display is monochrome (red) and contains several defects. The next video (above) explains about Holst’s new Spatial Atomic Layer Deposition, which can be used to deposit OLEDs as well. The video below discusses the Holst’s integration technologies for flexible and wearable systems. Holst’s Ashok Sridhar mentions organic LEDs a couple of times but I think these are regular LEDS.

The US Department of Energy (DOE) announced four new OLED lighting research grants as part of its Small Business Innovation Research (SBIR) program. The first project, granted to Universal Display in collaboration with IDD Aerospace, aims to develop a low-energy shelf phosphorescent OLED light targeted at aircraft interiors. According to the DOE, Universal Display plans to commercialize this technology in 2015. Back in 2011, UDC showcased an all-phosphorescent, white OLED luminaire designed into an under-cabinet lighting system . This development was also funded by the DOE back in 2009 . The warm-white OLED offer a power efficacy of 70 lm/W when operated at 190 lumens. Litecontrol is developing an OLED luminaire family for use in corridors and public spaces at night in which accurate color rendering is important. The third project goes to InnoSys, who’s developing a customized driver design for phosphorescent OLED lighting panels. The DoE says that currently all OLED panels use standard LED drivers, and this effort aims to produce better drivers that will be highly efficient and “smart”. The fourth project goes to Plextronics , and we already posted about it earlier .
Digitimes reports that Samsung Electronics plans to launch their direct-emission 55″ Full-HD OLED TV (the F9500 ) in Korea next month (June 2013). SDC still struggles with low yields, but they do plan to finally launch the TV in limited volume. According to earlier reports, Samsung’s OLED TV will cost about $18,000. That’s a lot higher then LG’s OLED, which costs $10,000 in Korea and $15,000 in the UK and in Israel (it will cost around $12,000 in the US , when it finally launches there). A couple of months ago it was reported that Samsung is actually considering to adopt LG’s WRGB structure in order to increase production yields and lower the cost. LG and Samsung are in talks to end their OLED IP disputes and are indeed considering cross-licensing relevant patents . But if the current report is true, than it seems that SDC decided to stay with direct emission after all. Samsung’s F9500 (full model number: KN55F9500) is a 55″ Full-HD Real OLED T V . The OLED panel, as we said before, uses direct-emission RGB OLED subpixels, hence the “Real” title. This TV features voice and hand UI recognition, smart TV features (the engine is 1.35Ghz quad-core CPU), new picture processing technologies and active-shutter 3D (with Multi-View support via optional $99 3D headphone glasses).

The OLED Handbook 2013 edition released!
At the SID Display Week 2013 (21-23 May in Vancouver) Comedd and Ardenne showcase their new novel technology for microdisplays. The companies introduce their FMTL (flash mask transfer lithography) technology that enables to pattern OLED microdisplays on sub pixel level.This technology works with a very special transfer mask. The organic layers are locally deposited through the masks via thermal heat input and transferred to the microdisplay. With this solution the sub-pixles can be smaller than 10 μm x 10 μm.Therefore adjacent red, green and blue monochrome sub-pixels on microdisplays can be manufactured, the color-filter replaced completely, eventually the efficiency increases significantly. OLED Microdisplays can be used for data eyeglasses like Googles one, but also in view finders for digital cameras.

Researchers from the Fraunhofer COMEDD Institute in collaboration with Von Ardenne Anlagentechnik are developing new direct-emission OLED microdisplays. These new displays will be more efficient and cheaper than Fraunhofer’s current microdisplays which use color filters. Fraunhofer use special vaporization technology developed at Von Ardenne. The process needed a complete redesign to suit OLED deposition. Fraunhofer’s COMEDD recently upgraded their OLED microdisplay production line with new equipment made by SNU Precision . We’re not sure how close is the new technology to commercialization, and what are the Fraunhofer’s plans for these new microdisplays. Currently all microdisplays on the market (from eMagin , Sony , MicroOLED and oLightek ) use color filters. eMagin is working on direct-emission OLED microdisplays , and in November 2012 the company said they hope to have prototypes ready towards the end of 2013 .

Plextronics has been awarded a $175,000 US DoE Phase 1 (Release 2) Small Business Innovation Research (SBIR) award for the design and development of low-cost processes of OLED lighting printed electrodes. Plextronics will partner with Electroninks (a startup that was spun-off from the University of Illinois to develop printable metal inks). The new process will integrate Plextronics’ conductive polymer inks (Plexcode HIL materials) with Electroninks printable metal inks. The printed metal lines will ensure high power efficiency and good light uniformity for large size OLED panels. Financial OLED lighting Technical / Research
On May 1st, LG Electronics launched the 55EM9700 OLED TV in Israel. I was invited to this press event which unveiled LG’s upcoming 2013 lineup of LCD and Plasma TVs, and of course the OLED one. Throughout the presentation, LG said that OLED provide the best image and that this technology is the next-gen display tech. The 55EM9700 isn’t available in Israel yet, but LG says they aim to launch in in July 2013. The price? 55,000 NIS, which is about $15,500. This is about the same as in the UK. LG’s salesperson said that LG are planning to launch more OLED TV models soon, all in the range of 50 to 60 inch=es (which is not really news ). The OLED TV looked great as ever.
LG officials say that LG Display aims to enter the small-sized OLED market with their new flexible OLED panels. The company reiterated their plans to start producing those in the second half of 2013 . Some reports suggest that LG Electronics aims to ship the first flexible OLED equipped phone in Q4 2013 . LG/UDC flexible OLED panel prototype LG also confirmed that the first flexible OLEDs will not really be flexible or bendable. They call this “unbreakable displays” as this will be the main benefit (these panels will also be lighter and thinner compared to regular OLEDs). But this is just the “first phase” towards real flexible displays. LG Display is currently using their 4.5-Gen OLED fab in Paju to work on these flexible displays. This won’t provide them with a a lot of capacity and the company now considers converting its 6.5-Gen LTPS line in Gumi to flexible OLED production, but that hasn’t been decided yet. LG Display’s flexible OLEDs will use polyimide coated substrate and direct-emission RGB sub-pixels (as opposed to LG’s OLED TV which use an WRGB technology – white OLEDs with color filters)

Indium-Tin-Oxide (ITO) is currently used in OLED panels for the transparent cathode (or anode in top-emission OLEDs). ITO is useful because it is conductive and transparent, but its supply is limited (even though companies are now harvesting ITO from recycled electronics devices) and it’s also brittle (so it’s not suitable for flexible panels) and so companies are looking for alternatives. Some products that use Cambrios Ag-Wires One possible alternative are silver wires (or ag-wire). This technology is pioneered by Cambrios – a company established in 2002 with an aim to commercialize Ag-Wire based products. Cambrios ClearOhm is a Ag-Wire coating material used to create transparent conductive layers. ClearOhm can be deposited on thin films using a roll-to-roll (R2R) process, and is compatible with plastic substrates. It’s also possible to use a sheet process on glass or plastic. Cambrios has filed over 175 patents for this technology and they claim they hold basic ag-wire patents. My friend Sri Peruvemba recently joined the company to become its chief marketing officer and he was kind enough to discuss their technology with me and help me with this article.
