Well it looks like monitors and TV will not for the most part be OLED for the next few years, but cell phone will be. Samsung is already the leader in Smartphones and they are already OLED so the whole game for the next few years will be the new Samsung emitter supply chain. Samsung seems to looking to other suppliers. UD says they are the only answer. While the spectrum outlook is not as big for now it still has lots if room for growth for UD depending on Samsung , the biggest customer, who is singing a completely different song than a few years ago..........". Samsung is investing heavily in OLED for mobile devices. To that end, it wants to build the world’s biggest OLED panel factory, which will operate by 2019, with a production capacity of 180,000- 270,000 panels a month.The estimated cost of construction and equipment together is an estimated $US16 billion ($20bn). It is also reported that LG, its Korean rival, wants to build three new OLED factories at a cost of almost $US9bn."
Hyperfluorescence-capable OLED emitters are claimed to outperform all previous generations of OLED emitters, boasting 100% quantum efficiency in a completely organic molecule without requiring the use of rare heavy metals. This is to be compared with the first generation of fluorescent compounds used for blue pixels in today’s cell phones and televisions, only 25% efficient, and the second generation green and red emitters that are 100% efficient but rely on the expensive rare metal Iridium and Kyulux claims, also suffers from an inferior color purity compared to the first generation.
Hyperfluorescence OLED emitters are said to combine the superior color purity of gen 1 materials and the efficiency of gen 2 materials, allowing for increased battery life or increased brightness without sacrificing color purity.
WiseChip plans to begin offering commercial display products incorporating Hyperfluorescence by Q4 2017 and will become the first OLED display manufacturer to offer these 4 th generation OLED displays for PMOLED applications.
How will the phosphorescent emitter market look in 2018, following UDC's basic material patent expiration?
The phosphorescent OLED emitter market is currently dominated by Universal Display who owns the basic patents to phosphorescent OLED emitters. All the major OLED makers (including Samsung and LGD) are using UDC's materials in order to achieve higher display efficiencies, beyond what is available from fluorescent emitters.
Universal Display holds over 4,000 issued and pending patents, but some of its basic phosphorescent patents are set to expire by the end of 2017. Honestly, it is very difficult to know exactly what effect this will have on the market - some analysts believe that it will carry very little effect while others say that this will open the door for other companies to sell competing phosphorescent emitters.
Will the Micro LED watch start the dawn of a new Era for Apple?
People are starting to recognise this technology," Lin said. “They are trying to get it into the smartphones, big and small screens by putting more pixels per area to try to get a higher resolution and higher brightness, while saving power consumption and extending the battery lifetimes of smart phones because micro-LED displays have the advantages of being self-emissive, high efficiency, high brightness and high turn-on/off speed."
While the iPhone 8 is expected to be the first Apple device to incorporate an OLED display, the company already has made moves to advance past OLED to micro-LED. One development, which Jiang identified as one of the two most important moves in micro- LED proliferation, was the purchase by Apple of LuxVue Technology in 2014 to research making micro-LED displays commercially viable for iPhones and other potential products.
Another interesting development Jiang identified is that some companies are currently working on making giant displays or television screens using micro-LED technology to provide ultra-high brightness, resolution, contrast and turn-on/off speed. He noted Sony has made some strides in that area, and several other companies are interested in developing the technology for their own products.
As for what the future holds, both speculated emerging three-dimensional (3-D) and AR, or augmented reality, micro-LEDs, with their outstanding properties, especially high turn on/off speed, could be the next to become part of the mainstream. They also feel the surface of micro-LED technology has just been scratched.
Google Invests 15 Million USD in University Spin-out Focused on Micro LED Technology Google Inc has invested 15 million USD for a 13 percent stake in Glo, a university spin-out focused on creating nanowire-based LED-displays for mobile phones and smart watches as well as AR- and VR-applications.
The Swedish news agency Rapidus has obtained documents from Glo showing that a share issue directed solely towards Google Inc. took place during the summer.
Glo, located in Silicon Valley and Lund, Sweden, has been commercializing its technology for creating direct view displays consisting of nanowire-based LEDs since 2008. Over the years the company has attracted close to 140 million USD from a series of heavy-weight investors including Wellington Partners and Sweden-based Foundation Asset Management.
Glo’s display technology is an example of what the industry refers to as micro LED, giving better contrast and lower power consumption than LCD screens while yielding higher overall brightness than OLED. The last few years, both Apple and Facebook-owned Oculus have acquired start-up companies within the field of micro LED.

The small diode size of micro LED-displays makes it possible to increase the resolution on very small screens, for example in smart watches or VR- and AR-goggles like Google Glass.
Rapidus has been unable to reach Glo’s CEO Fariba Danesh or chairman Ajit Nazre for comment on the funding round. According to Glo’s annual report for 2016, the company is expecting a total of 45 million dollars from this funding round, partly dependent on certain mileposts being reached.
Glo’s technology is originally based on extensive research conducted at the Center for Nanoscience at Lund University.
While many thought it would take three years to get Micro LED displays to become available in the market due to technological bottlenecks, it looks like it will be a lot easier than many thought.
According to Digitimes, which chatted to Charles Li, chairman and CEO of Taiwan-based Micro LED maker PlayNitride micro LED production is not as difficult as originally expected.
His outfit is planning to start trial production in the second half of 2017.
While the process of mass transferring Micro LEDs has often been cited as a major volume production barrier, PlayNitride has attained lab yield rates of over 99 percent in mass transferring and placing Micro LED chips, Li claimed.
It takes about 10 seconds to mass transfer 200,000 Micro LED chips in laboratory and based on the speed, it will take 10 minutes to produce a 5-inch Micro LED smartphone panel, Li said.
The key factor affecting Micro LED panel production has shifted from how to break through the technological bottlenecks to how to decrease production cost, Li noted.
A Micro LED smartphone panel will cost about US$300 which is a huge price in comparison to AMOLED's US$70-80 and LCD's US$15, Li said.
It is difficult to use Micro LED panels in smartphones for the time being - however they may end up in smartwatches, automotive transparent displays and VR (virtual reality)/AR (augmented reality) devices.
Micro LED chip sizes are about one percent of those of LED chips and allow pixel pitches to be reduced to micrometer level, making it easily for Micro LED displays to reach resolutions over 1,500ppi, much higher than 400ppi for Retina LCD displays.
US-based LuxVue Technology, which has been acquired by Apple, owns a technology patent for mass transfer based on static absorption. US-based eLux, of which Foxconn Electronics and Sharp are shareholders, applies fluid dynamics to mass transfer.
We are excited to drive cadmium-free quantum dots as a phosphor replacement in OLED displays, in concordance with Apple's recent announcement regarding their integration of quantum dot and OLED technologies into QD-LED for future iPhone displays. Our materials are the foundation for accelerating development of QD-LED displays and making them a reality for mobile devices. QD-LED display form factors are more desirable for mobile devices and quantum dots as a phosphor replacement will radically improve color performance and energy efficiency over current OLED technology," said Toshi Ando, Quantum Materials Corp Senior Director of Business Development.
"Extracting and optimizing high levels of performance from cadmium free quantum dots is not trivial and our team continues to be on the forefront of discovery in this exciting area of nanomaterials. This achievement is even more significant when you consider the fact that it is being accomplished in a high-volume production environment and is not simply a small one-off batch science experiment requiring days of post processing. Our process is quickly scalable to industrial-volume production at a price point commercially viable for next-gen QD-LED display development efforts such as Apple's. We have already made a great deal of progress working with our film partners to integrate our materials into optical film for LED display applications and it was a natural progression for us to leverage that experience into the next technological leap into QD-LED photo resist film applications," concluded Quantum Materials' President and CEO Stephen Squires.
According to OLEDNet, Material Science has finished the development of a new fluorescent blue emitter and host system, which it now aims to offer to Samsung and LGD for commercial AMOLED production. Material Science currently offer ETL and HTL materials to OLED makers, with sales reaching $5.8 million in 2016. The company expects its sales to exceed $8.8 million in 2017.
