New OLED gadget: Turnlights Flaps
Jul 15th
The Flaps ceiling lamp (designed and made by Italian maker Turnlights) uses 18 Philips Lumiblade GL350 OLED panels in a multi-tile system. Each OLED can be rotated on two axes. They say that this lamp provides 360-degrees ambient light and it works in every location. The lamp is made from aluminum (available polished, satinised or bronzed) and the total dimensions are 147x406x cm. We do not know the price and availability date yet.

Futaba’s flexible and transparent OLED at SID 2013
Jul 10th
It turns out that Futaba ‘s booth at SID 2013 was quite interesting. The company showed off their transparent and flexible PMOLED panels, and they also show the new OLEDry-S desiccant. Check out this nice video tour of their booth: The first item they show is the Lenovo S-800 that uses Futaba’s 40% transmissive 2.4″ QVGA (240×320) PMOLED panel . The S-800 was unveiled towards the end of 2010 , and sadly it seems that it’s the only device to use Futaba’s transparent OLEDs. Next on display are several curved flexible PMOLEDs (Futaba calls them film OLEDs). The company seems to be showing the same 3.5″ (256×64) full-color flexible PMOLED prototype unveiled at CEATEC 2012 . Some of the panels are touch (capacitive) ones. One cool prototype is a pen with a tiny flexible (curved) monochrome OLED. Finally, Futaba is showing their new solvent-free liquid desiccant, the OLEDry-S, which can be used in flexible and transparent OLED panel production

More details on DKU’s new efficient blue OLED
Jul 5th
A few days ago we reported about new research from Dankook University (DKU) that developed the world’s most efficient blue OLED emitter . Today I talked with Professor Lee Jun Yeob, who’s in charge of that research at DKU, and he explained his research further. It turns out that in that particular research, they developed a new host material for blue OLEDs, and not a new emitter. The 30.1% efficiency they quote is external quantum efficiency. The blue emitter itself is a phosphorescent OLED – a common emitter known as FIrpic (Iridium based). Universal Display were not involved in this work. Professor Yeob says that their new host gave much longer lifetime compared to other host materials, but the lifetime level is still poor as FIrpic is very unstable, in fact just 100 hours at 1,000 cd/m 2 . The researchers are looking for a better blue phosphorescent emitter to obtain long lifetime with the new host material. I asked Professor Yeob how close is this new host material towards commercialization

Sumitomo developed a new P-OLED inkjet printing technology
Jun 27th
Sumitomo Chemical announced it has developed a new P-OLED inkjet-printing technology that achieves 423 PPI on glass substrates sized 370×470 mm. We don’t have more information about Sumitomo’s new production process, but apparently it isn’t ready for commercialization yet as the company says they will “continue to improve the performance and process of P-OLED materials”. Panasonic printed P-OLED 56-inch OLED prototype Panasonic used Sumitomo’s P-OLED materials in their 56″ 4K2K printed OLED TV prototype shown at CES 2013. Panasonic and Sumitomo has been collaborating on OLED TVs since 2009 . The companies hope that ink-jet printing will enable them to lower the production costs of OLED panels compared to evaporation based production. Panasonic aims to launch their first OLED TVs in 2015 . The company is collaborating with Sony, and may setup a production-JV together (although if this happens, it’s not clear which production technology will be used). Sumitomo Chemical is also developing printed OLED lighting panels. Just a few weeks ago the company unveiled new flexible structured ink-jet printed P-OLED lighting panel prototypes . Sumitomo plans to start volume production of such panels by March 2015 (fiscal year 2014) – using both ink-jet and roll-to-roll processes.

Philips Pixelate
Jun 21st
The Pixelate lamp (designed by Pablo Alvarez for Birot) is a suspended OLED lamp that is inspired by the undulating movement of a manta ray sliding across the air. The lamp is made from several weaved layers of stainless steel, and each OLED panel has an independent movement. The Pixelate will be available by September 2013, and will come in three sizes (the prices below aren’t final yet): 6×6 pixels (720×720 mm), 6 GL350 panels: $2,550 7×7 pixels (840×840 mm), 9 GL350 panels: $4,150 8×8 pixels (960×960 mm), 12 GL350 panels: $7,200 OLED type: Lumiblade GL350 panels OLED lamps

Samsung Galaxy S4 Zoom
Jun 15th
The GS4 Zoom is an Android v4.2 smartphone that has a 10X optical zoom and a 16 mp sensor. The display is a 4.3″ qHD (960×540) Super AMOLED display. Other features include a 1.5 Ghz dual-core CPU, 1.5 GB of RAM, 8 GB of internal flash and a micro SD slot. Despite the S4 in the name, it isn’t as powerful as the GS4 , but Samsung says it has the “stylish heritage of the latest GALAXY S4 smartphone”. The GS4 Zoom will launch towards the end of 2013, Samsung wouldn’t reveal the price yet. OLED type: 4.3″ 960×540 Super AMOLED Digital cameras Mobile phones

IHS: flexible display shipments to reach 800 million units in 2020
Jun 6th
IHS says that flexible display shipments will grow quickly in the near future. They expect about 3.2 million such displays to ship in 2013, and this will grow to almost 800 million displays by 2020. In terms of revenue, the total market will reach $41.3 billion in 2020. The leading display technology for flexible displays will be OLEDs, which will account for 64% of the market in 2020. IHS classifies flexible displays into four generations. The first one are plastic-based displays that are unbreakable, but are still flat. The second-gen ones are conformable and can be molded to curved surfaces. The third-gen panels are bendable/rollable – and can be manipulated by end users. The fourth generation are disposable displays- so cheap that they can replace regular paper and be thrown away after use. Source: IHS Flexible OLED Market reports

Samsung’s Galaxy S4 Active phone uses a 5" Full-HD LCD panel
Jun 5th
Samsung announced the new Galaxy S4 Active phone – that is water and dust proof (it can be submerged in up to three feet of water for up to 30 minutes). The display is a 5″ Full-HD (443 ppi) panel – but it is an LCD and not an OLED like in the regular GS4 . The S4 Active has a 1.9Ghz quad-cre CPU, LTE, 8mp camera and Android 4.2.2. It will launch in the UK and the US during the summer. Samsung Competing technologies Mobile phones

CPI posts some updates on their OLED developments
Jun 2nd
The UK’s Centre for Process Innovation (CPI) posted some updates on their OLED program. They have recently produced defect free OLED lighting samples. They managed to produce panels that has large (over 250 cm 2 ) emissive areas (they are producing these panels on 8″ substrates and so could exceed 160×160 mm panels). The CPI developed two kinds of panels – the first uses small molecule materials and the second uses full solution-processable P-OLED materials. They have also produced samples that use a hybrid structure with a PEDOT layer (deposited using a slot die process) with an evaporative emissive layer (that has better efficiency and performance compared to the P-OLEDs). The 154×154 mm example shown above is the hybrid structure. The CPI also sent us some updates on two of their collaborative programmes that use their OLED prototype line facility . First up is FLEXIBILIS, which aims to investigate and develop low-cost flexible substrates with novel high quality barriers as well as TCOs (supported by metal grids), deposited by inline capable PVD or PECVD methods. As part of the project, they will demonstrate large-area OLED and OPV panels that employ the new substrate, barriers and TCOs. Another program is called HiPBe, another collaborative R&D project that focuses on flexible high and ultra-barrier polymer based substrates and encapsulant materials (for flexible OLED lighting, displays and DSSC solar cells).

NHK developed a 8" flexible OLED panel prototype
Jun 2nd
NHK’s Science & Technology Research Laboratories (STRL) unveiled a new 8″ flexible OLED prototype panel. The panel features a resolution of 640×480 (100 ppi) and is based on an amorphous InGaZnO (a-IGZO) TFT backplane. STRL says that the red emitter material is a new phosphorescent material that is made from a benzoquinoline derivative host doped with a platinum based complex. The encapsulation is made from a polymer material. source: TechOn Flexible OLED Technical / Research Backplane Oxide TFT Encapsulation Phosphorescent
