OLED-Info is the web's leading resource on OLED TVs, displays and lighting.
OLED (or AMOLED) screens are efficient, clean, thin and bright, and are becoming popular in mobile devices. We bring you daily news and resources on this exciting new technology!
Recent OLED news:
An LCD works by selectively blocking light from a backlighting unit (BLU, usually made from LEDs) using a crystal which changes its polarization-filtering when voltage is applied. An electrochromic device is similar in idea but more simple as they can be turned from being transparent to being opaque. These kind of displays haven't been commercialized successfully yet due to fragile materials and material mismatches with the electrodes.
But new research at Bilkent University shows that graphene can be used to create such a device that features high percentage optical modulation, optical tuning properties in the UV to infrared, good electrical conductivity with no material mismatches. The display is mechanically flexible.
Garmin's Vivosmart is a smart band that includes a fitness tracker and notification display from your smartphone (iOS and Android). The Vivosmart uses Futaba's flexible (curved) 1.4" 128x16 white PMOLED panel.
This device can count your steps, monitor your sleeping and calories burned and also measure the distance you've walked. The band is powered by low-energy bluethooth and can last seven days between charges. It is also waterproof up to 50 meters and is compatible with heart rate monitors and bike speed sensors.

BOE Display announced that it has been awarded a 124 million RMB (about $20 million) subsidy from the local Chinese government at Hefei Xinzhan towards its Gen-8.5 OLED fab in the area. BOE currently has a Gen-8.5 pilot fab in Hefei, and it seems that this report confirms that BOE Display decided to go ahead and build a real mass production Gen-8.5 OLED fab.
BOE's expected total investment in that fab is currently estimated at 6.7 billion RMB - or just over $1 billion. I do not have any information regarding when they expect to start producing panels at that fab. Using their existing pilot line, BOE produced 55" 4K OLED TV samples (you can see one above) - and these were on display at SID 2014.
UK's R&D institute, the Centre for Process Innovation (CPI), published a nice video showing how OLED technologies can make aircraft safer, more efficient and more entertaining. We're still a long way before this kind of solutions are available...
In February 2014, Spike Aerospace announced that instead of conventional windows, it will use curved, super-thin digital displays in their upcoming supersonic business jet, the S-512. The S-512 will be available in 2018, and will reportedly cost $80 million. Spike did not mention OLEDs specifically, but it makes sense that OLEDs will be employed for this advanced aircraft.
Google's Nexus 6 (produced by Motorola) is the first phone to run the Android 5.0 Lollipop OS. The Nexus 6 use a large 5.96" 2560 x 1440 AMOLED display. Other features include a Qualcomm Snapdragon 805 CPU @ 2.7Ghz, a 3220mAh battery, 13-mp camera with OIS and 32GB (or 64GB) of internal storage memory.
The Nexus 6 will ship towards the end of October 2014 for $649 unlocked (it will also be available via network carriers later).

In June 2012 we first heard about AIV-BEX's ambitious AMOLED project. Later in 2013 we posted more details about this 4.5-Gen Oxide-TFT AMOLED production fab project. A few months ago I heard that AIV-BEX abandoned the OLED project, but according to some new information this is not true, although they do face some delays to their original plan.
In 2013 AIV-BEX planned to start production in 2014, but now according to the OLED Association, this was delayed to Q4 2015. According to a private investor on a forum, the company assured him that the project is still running but is slower than expected.
In early 2014, Pioneer and Mitsubishi Chemical announced that they began to mass produce OLED lighting modules made with a "wet coating system". Soluble OLED processes should offer a great production cost reduction - but Mitsubishi's panel suffered from limited lifetime (15,000 hours).
According to a new report from Japan, Mitsubishi managed to double the lifetime, and their newest panels offer 30,000 hours. This was achieved by new longer-lasing OLED materials and a different device structure. Mitsubishi already shipped panel samples to lighting equipment makers and will setup up their marketing effort soon via their Pioneer JV (MC Pioneer OLED Lighting).
