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.

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.

MicroLED simpler to make than expected


Still too expensive for smartphones

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.

Samsung Electronics will focus on enhancing LCD TV technologies with materials for better picture quality given the relevant infrastructure it owns, The said the CEO of Merck Korea.

"It seems to be that Samsung Electronics is focusing on developing their existing technology. There's a great gap in competition by using the technology they already have, making small changes," Merck Korea CEO Michael Grund said.

"We make a material but to understand how that material performs, you have to make an application, to create production that makes sense economically, and to make a product in that way for lifetime. How to make mass production is a different story," Grund said.

The executive said OLED display technology is still new and expects products with OLED displays, specifically those with larger displays, to appeal to the affluent, not the masses.

"The most interesting part of OLED is not to compete in areas where LCD is by today. OLED is flexible by nature and that means OLEDs will be highlighted when they are put in home entertainment devices, architecture, mirrors and vehicles not just for TVs," said the executive.

Although market leader Samsung Electronics is still hesitant to jump into the large-sized OLED TV market, the executive said Merck's plan to become a leader of OLED materials by 2018 has not been changed due to the rise of OLED-embedded products from smartphones to in-vehicle infotainment systems.

Merck, which dominates the market for liquid crystals for displays, is one of dozens of players in the nascent OLED market. Others include Universal Display, Dow Chemical and BASF.

OLEDs are used in displays for mobile phones, digital cameras and other gadgets and are popular for portable devices that are used outdoors.

"The OLED market has a promising future, but right now, there should be price for value. Also, you have to get some premiums for your money. The product has to be produced economically, otherwise only the very affluent can afford it. But if you go to Volkswagen, which has a similar setup like Samsung, they are not famous for being the first but they are the biggest and they have big money," Grund said.

"And when they move, they demand cost efficiency. The ideal is most likely that OLEDs will start with high-end buyers, where you use the nice form factors to differentiate by design from competitors, and then later there is a bigger market."

He declined to specify whether or not the move by LG Electronics to OLED TVs will pay off.

In an attempt to enjoy a "first-mover advantage" in the OLED TV market, the LG Group of technology affiliates ? LG Electronics, LG Chem, LG Display, LG Innotek ? teamed up to promote OLED TVs. LG Electronics is the No. 2 TV maker after Samsung.

But LG's OLED-first TV business strategy is facing challenges amid weak demand with lukewarm response from manufacturers and from Samsung's aggressiveness to promote TVs with quantum dot displays.

Samsung still believes advancements in quantum dot technology such as quantum dot material without cadmium have made them useful for television manufacturers giving them a competitive edge in the industry by maintaining its existing infrastructure, which means no heavy costs.

Creating better color with color tuning features has become a key selling point for display manufacturers.

"OLED will not replace one to one with LCD. OLED will display in some areas, maybe in high-end areas to compete against LCD, but by the properties of OLED, you can move into areas which cannot be addressed by today's LCD displays. The form factors so you can make it easier, for instance, bendable, flexible and transparent. All these things are easier to realize with OLED technology," Grund said.

Sumitomo Chemical Develops New OLED Printing Technology to Halve Panel Production Cost
Sumitomo Chemical, the Japan-based chemical giant, is reported to have successfully developed new technologies to facilitate more cost efficient OLED display manufacture. According to Nikkei, the new materials and equipment the company introduced could possibly bring down the current production cost of OLED panels by 50%, which is able to further reduce the selling prices of OLED TVs and expand the penetration of OLED products.

Sumitomo Chemical introduced self-developed macromolecular materials formulated for the emissive layers in OLED panels. With the new materials, OLED panels can be manufactured through efficient inkjet printing technology. Compared with small molecule organic LED (SMOLED), Sumitomo Chemical’s ‘PLED’ technology integrates red, green and blue emissive layers into a single white emitter that enables simpler OLED printing processes.

The mainstream process the majority of OLED manufacturers adopt so far is the evaporation-based process, in which red, green and blue emitters are evaporated and deposited onto glass substrates under vacuum. It; however, requires expensive equipment and fails to keep most of the materials, reflecting fairly high production cost. On the other, the OLED printing process, though with lower manufacturing cost, also meets technological hurdles during the coating process of large-sized panel production.

The chemical company is able to print its single emissive layers onto glass substrates evenly. To put the PLED technology into practice, it also constructed new printing equipment.

New OLED technology is said to be co-developed by Sumitomo Chemical, JOLED, and overseas display makers. JOLED’s 21.6 inch OLED displays for medical monitors, to hit shelves in fall 2017, first adopted the new materials. Sumitomo Chemical also promoted this new technology to LG Display to use it in the Korean firm's OLED TVs expected to enter the MP stage in 2019.

JOLED on 17th May announced the first printed 4K OLED display that came in a size of 21.6 inches. It started offering samples for medical monitors and attempted to expand the product’s application base to television, gaming and other uses.

JOLED already received orders from Sony. Nobuhiro Higashiiriki, CEO of Japan Display Inc. expressed on the previous press conference that the OLED printing technology is anticipated to be widely used in the production of mid-sized displays in the future.

On September 7th, CYNORA hosted a TADF symposium in Frankfurt, Germany. Approximately 150 attendees from Europe, Asia and the US attended the event.

While there were many experts from academia, there were also plenty of guests from the OLED and the general display industry as well as some financial analysts that wanted to get more information about this exciting new technology.

The keynotes of the event were delivered by LG Display and Samsung Display who showed their plans for the next-generation OLED displays. Both speakers from these major OLED panel producers pointed out that they really need a high-efficiency blue emitter and that they see a good potential for TADF emitters to deliver the required specifications. TADF blue emitters seem to be such a major topic for LGD and SDC that both speakers also asked for closer collaborations with them on that topic.

For the OLED experts, there were also several technical presentations by speakers from University of St Andrews, University of Durham, Seoul National University, SungKyunkwan University, TU Dresden and Heinrich-Heine-University Düsseldorf and others. The technical presentations showed how much progress had been made in the last few years to understand TADF emitter materials better.

The symposium closed with a presentation by CYNORA where an update on their development for blue TADF emitter was shown. The company has made more progress towards their goal to commercialize their first product by the end of the year. There is still some improvement of the lifetime and of the color needed to reach the panel maker´s specifications, but CYNORA claims that they are still on track towards this target.

"With this technology Cynora will be able to market the first high performance blue emissive material, the most requested material from OLED screen manufacturers. High-performance blue materials will allow a significant reduction in energy consumption and higher display resolution , "says the company in a press release.

Already, because the weakness of OLEDs is the blue color emission, which fails to keep pace with the other two primary colors with regard to durability and energy efficiency. The problem is that you use three fluorescent layers (blue, green and red) to get white, and blue is therefore crucial.

LG Display and Samsung Display will collaborate with Cynora to advance the research and development and intellectual property portfolio. However, this will not be a joint work: the two South Korean companies will work with the German company separately .

"Liquidity injection will also be used to strengthen our worldwide presence as a provider of high-efficiency broadcasting materials. We will market our first blue product by the end of 2017, followed by green and red, " said Gildas Sorin, CEO of Cynora .
