[Exclusive] The Lowdown on VueReal after Its Debut of Micro LED Display
Earlier in May, the world’s highest PPI emissive Micro LED display was announced. The whole industry was left baffled with knowing that it came out from a young Canadian startup- VueReal. When other companies- some of them are major in other application sectors-are still moping over poor yields and technological difficulties during Micro LED’s manufacturing processes, the launch already spoke for the company’s competency.

LEDinside had an exclusive interview with Reza Chaji, the founder and CEO of VueReal to get a grasp of the company and the CEO’s insights.

Starting out as an OLED display technology developer, Chaji realized, after more than a decade with solid experience in OLED, that the organic materials limited the performance of those displays, most notably when powering them at high brightness and/or high temperature. Other problems such as waste of materials during the deposition process and inefficient power consumption at high brightness had the CEO reconsidered the reliability of OLED and shifted his focus onto Micro LED. Following that was the establishment of VueReal in 2016.

Despite the faith, the CEO was not blind about current technological difficulties of Micro LED. The size of Micro LED that makes harder the chip production, poor yield and throughput of the transfer technology, and current control issues in the modularization process are factors hindering the commercialization of Micro LED, he explained.

Yet, all that makes us wonder even more how VueReal could still create a microdisplay with seemingly reliable Micro LED technology at this time considered a fairly incipient stage.

Major Technologies Behind the 4K 6000ppi Micro LED Display

VueReal’s Chaji shared with LEDinside the three major technologies behind the 4K 6000ppi Micro LED Display.

The one-year-old display company designs a structure for its own micron-sized LED chips. It purchases epitaxial wafers from upstream suppliers and structures individual pixels via the Continuous Pixelation technology. The smaller the chips are, the cheaper the finished product could be, said Chaji. The technology enables sub-micron pitches with a high density of extremely small pixels that are rather subtle and hardly recognized individually. The special structure improves the overall performance of the Micro LED chips. These low power chips create high efficiency, high contrast, and high brightness at a lower cost. They are said to hit a brightness of 10,000 to few 100,000 nits, so much brighter over other display technology. An extremely fine pitch microdisplay, formed with this technology, does sound like something especially intended for devices such as AR head mounted displays (HMD).

Here LEDinside makes a wild guess that the Solid Printing technology is probably the major linchpin backing up VueReal’s speed and quality of its production. We’ve been addressing bad yields of incumbent mass transfer technologies and how that is troubling companies and delays the possibility of mass production. However, the Solid Printing, Chaji explained, offers high yield and throughput across different applications and is able to produce a large, high-resolution TV in minutes instead of few 100 hours.

According to one of the CEO’s patents, after the fabrication of Micro LED chips, VueReal’s engineering team place and align them on a donor substrate with corresponding contact pads on a receiver substrate. The donor substrate is powered to give a net force to adsorb those Micro LEDs and is move close to the receiver substrate, ready to transfer selected Micro LED chips onto it. When two substrates are moved together within a defined distance, voltages of the power supplies of the two substrates are then adjusted to create a force that transfers selected Micro LEDs onto the corresponding contact pads on the receiver substrate, and the other towards the donor substrate to keep other unselected micro devices.

To read the full version of the patents, click here.

The CEO told LEDinside that the team believe that the best and lowest cost repair is the one that is not done. Therefore, VueReal’s transfer technology is developed based on this goal to attain a very high yield without repair.

VueReal is also developing its own driving scheme for its Micro LED displays. In the modularization process, the challenge lies in current control. Micro LEDs certainly do not need high current to run, while it is hard to control the operating current with traditional backplanes. It often leads to poor outcomes. With its proprietary driving scheme, the startup is able to drive the chips with stable, low but sufficient currents in correspondence with the efficiency of Micro LEDs on conventional backplanes as normal.

As display is very multidisciplinary technology, several pieces need to fit perfectly to complete the production puzzle. Therefore, VueReal is developing, on its own or in collaboration with its partners, different parts of the puzzle including the chips, components, equipment, circuitry, and transfer technology.

Where Can We See VueReal’s Micro LED Displays Next?

Chaji revealed their products will first target the AR and VR devices and applications featuring small-sized displays, such as replacing DLP projectors. Once the company finishes verification and assessment, it will provide samples to interested clients by 2018. The mass production is expected to start following the customer assessments.

VueReal will also offer Micro LED displays for larger applications such as TVs and smartphones. Those samples, compared with LED and OLED displays, will stand out with their higher performance, significantly lower power consumptions, and higher reliability.

CEO’s Outlooks for Display Technology

“For the next few years, OLED will still mainly focus on the smartphone market,” said the CEO. Acknowledging the wide reception of OLED in the market, Chaji at the same time also pointed out a few problems that suggest OLED might be displaced by Micro LED.

“There are big investments and capacity expansion, especially in China, but not significant luck in terms of high volume productions. Besides, Samsung holds most of the manufacturing know-hows. The encapsulation of OLED displays is still an issue for fully flexible rollable displays,” he continued. Not only just the encapsulation but the resolution and brightness of OLED displays are hard to enhance as well.

On the other, Micro LED, despite poor yields and technological hurdles, outperforms in terms of brightness, HDR compatibility, power consumption, and, what Chaji emphasized over and over again, reliability. In addition, Micro LED with VueReal technologies not only addresses the yield issue but also it can easily take advantage of the backplane development and capital investments for OLED manufacturing. In addition, “Micro LED performance gap with the other display technologies is so wide that will make the catching-up game impractical,” he contended.

Also, micro-LED is future proof. “What is good with Micro LED displays is that because Micro LED is small, it leaves more room in a pixel. In this case, a display can be more than just a display. You can do more in a display, perhaps embedding other elements in each pixel, for better user experience and enhanced functionality,” concluded Chaji.

From lasers to LED: Advances in cinema display technology
By Patrick Von Sychowski15 August 2017

Advances in display technology are providing cinema goers with sharper images and even greater dynamic range.


Laser illuminated projection has become that standard for new cinema deployments, as well as for replacements for the first generations of xenon-based projectors coming to the end of their commercial life.





“Laser projectors are still expensive at the higher brightness end, but laser excited phosphor sourced devices are making the technology viable for smaller screens now,” notes Dr David Monk, Chief Executive of the European Digital Cinema Forum (EDCF).

“This represents a major area of growth and change.”

While all-laser multiplexes were a novelty as recently as last year, there are now multiplexes even with all-RGB lasers, such as the AMC Universal Citywalk in Los Angeles, which has Christie RGB 6P lasers in all 19 screens.

NEC was first with blue phosphor lasers (BPL) and has come to dominate the field.

While Barco offers a wide range of BPL and RGB lasers, Christie has focused increasingly on its RGB laser projectors, arguing that falling costs of these means that installation of BPL will peak in 2017.

Meanwhile, IMAX is also ramping up its laser projector deployments, and Dolby Cinema competes for premium high-end experience at cinemas such as AMC and Wanda, with China being the biggest growth market.

Wanda will have 360 IMAX screens by 2020, while Dolby Cinema opened its 100th screen this summer, most of them with AMC.

High dynamic range (HDR) and brighter 3D are the primary driver for RGB laser projection, while lower lamp and maintenance costs are among the key selling points of BPL projectors. HDR is also possible with Sony’s current SXRD projectors, which are used for the Eclair Colour systems deploying in Europe.

Sony will start shipping its SRX-R800 Series 4K laser projectors end of this year in Europe.

Yet the latest cinema technology innovation is one that does away with projection entirely.

“This represents a major area of growth and change” - David Monk

Samsung stunned the cinema industry when it demonstrated its direct view Cinema LED screen at an invitation-only event during the CinemaCon trade show in Las Vegas in March. In early May Samsung’s screen passed DCI compliance certification and on July 13 the first commercial installation was unveiled in Seoul’s Lotte Cinemas World Tower 13 multiplex auditorium dubbed ‘Super S’.

It is arguably the biggest change in cinema since the advent of film projection in the 1890s.

“Today is the day when new innovations in the film industry will begin,” remarked Kim Hyun-suk, head of Samsung Electronics’ video display business, on the occasion of the inauguration of the first installation.

“Cinema LED will vividly reproduce the picture quality and sound that movie screens have not shown in the past.”

It is believed that Samsung will next open a Cinema LED installation in a Los Angeles cinema in partnership with GDC Technology and Harman, which it acquired last year. Samsung has a stated ambition of capturing a 10% global cinema screen market share by 2020, which would equate to 20,000 screens world-wide.


Video IBC Big Screen Executive Producer Julian Pinn reveals what will be discussed during the four-day conference programme


Developed from its consumer television technology, the Cinema LED screens consists of 96 LED panels with edge-to-edge diodes that when assembled produces a 4K (4,096 x 2,160) image on a screen that is 10.3meters (33.8ft) wide in size.

The HDR screen offers peak brightness of 146 footlamberts, almost ten times as bright as conventional cinema projection.

The screen has JBL speakers bordering the screen - instead of behind it - that use JBL’s Sculptured Sound proprietary audio-processing.

Samsung has been engaging with Hollywood studios to ensure a steady stream of film mastered for the higher brightness and wide colour gamut.

Samsung is not the only proponent of this technology, with Sony also having demonstrated its prototype Crystal LED (CLEDIS) screen at CinemaCon and CineEurope.





Samsung Cinema LED Screen



“The cost of the solution we’re developing now for cinemas will initially limit Crystal LED’s appeal to a small handful of screen owners,” said Oliver Pasch, Sales Director Digital Cinema Europe, Sony Professional Solutions Europe.

“But in time, who knows how quickly the price will come down, and to what level.”

No price has been revealed for Samsung’s Cinema LED, but it is said to offer sustained light output for over 100,000 hours, thus offering a total cost of ownership that is lower than a laser projector over a five-year time span.

While Samsung claims that at 10 meters it is larger than half of all the cinema screens worldwide, it is unlikely to be used for large screens initially.

Although not deployed yet, Samsung’s partner GDC Technology is promoting its Jetreel 8K variant “ultra-premium large format cinema experience” that scales the Samsung Cinema LED for larger venues.

The introduction of new cinema technology will be more complex to manage than the initial switch from film to digital.

Michael Karagosian, founder of MKPE and Cinepedia, and Co-Chair of ASC’s Next Generation Cinema Display Committee notes that “the cinema market today looks a lot more like the cinema market of the 1980s and 1990s, than that of the digital transition.”

Then and now, the specification of new technology was driven solely by technology providers, instead of industry groups like DCI.

Managing the critical quality of colour consistency across competitive technologies, for example, requires an institutional process that does not now exist.

Mini LED commercialization expected soon
Siu Han, Taipei; Adam Hwang, DIGITIMES [Thursday 31 August 2017]
Because of technological bottlenecks in the production of Micro LED chips, Mini LED chips are expected to be a market focus when commercial applications become available as early as the end of 2017, according to industry sources.

Sony has applied Micro LED technology to CLEDIS (crystal LED integrated structure) large-size displays for which prices are extremely high, the sources noted. A major technological bottleneck in manufacturing Micro LED chips is mass transfer, the sources said. Production of Mini LED chips does not entail mass transfer process and is thought to be more practically feasible.

According to the largest Taiwan-based LED epitaxial wafer and chip maker Epistar, Micro LED chip sizes range from 20 to 30 microns while those of Mini LED chips are 100-200 microns. Epistar has been in talks with clients about using Mini LED chips to make large-size high-end indoor displays for movie theaters, museums and commercial facilities and is likely to begin shipments in the fourth quarter of 2017 at the earliest, the company said.

Despite higher production cost for Mini LED chips than for LED chips used to make fine pixel pitch LED displays, Mini LED displays looks promising in terms of market accpetance, Epistar noted. Mini LED chips used in high-end displays may take up 5-10% of consolidated revenues in 2018, Epistar indicated.

Some LED packaging service providers have cooperated with LCD panel makers to use Mini LED chips in backlighting of high-end automotive display panels, the sources indicated. Display quality of such panels will be better than that for OLED panels and HDR (high dynamic range) performance, the sources said. Adoption of Mini LED chips for backlighting of high-end automotive display panels is expected to begin the earliest in the second half of 2018, the sources indicated. Taiwan-based TFT-LCD panel maker Innolux and LED packaging service provider Lextar Electronics are in preparation for such adoption.

Panasonic, Samsung & 20th Century Fox Plan HDR10+ Certification ProgramPlatform to be open and royalty free



By: TWICE Staff






Share 6










Panasonic and Samsung are teaming up with 20th Century Fox to create an open, royalty-free dynamic metadata platform for high dynamic range (HDR)through a certification and logo program, tentatively called HDR10+.

The three companies intend to form a licensing entity that will begin licensing the HDR10+ platform in January. The entity will license the metadata broadly to content companies; manufacturers of Ultra HD TVs, Blu-ray Disc players/recorders, and set-top boxes; and SoC vendors. Licensing will be royalty-free with a nominal administrative fee. Further details will be announced at CES 2018 in Las Vegas.

Partners who wish to adopt the platform for HDR10+-compliant products will benefit from system flexibility, said the companies in a press release, allowing a variety of partners, including content creators, content distributors, TV manufacturers and device makers, to incorporate this platform and improve the viewing experience for audiences.

“As leaders in home entertainment content and hardware, the three companies are ideal partners for bringing HDR10+ into the homes of consumers everywhere,” said Jongsuk Chu, senior VP of Samsung’s visual display business. “We are committed to making the latest technology available in our TVs and are confident that HDR10+ will deliver premium quality content and enhance the way you experience television programs and movies in the home.”

"OLED is a dead-end; QLED is the future'





Samsung opts for smarter smart TV experience

Samsung has powered-up its Smart TV experience with a 'One Remote' control and an upgraded voice recognition feature that will allow consumers to use smart features more smartly, says its development team.




Like the insatiable desire for faster connectivity and more storage, the desire for lifelike TV images will never change. Samsung's introduction of quantum dot (QD) LCD TVs in 2015 -- branded SUHD then but now QLED -- was a statement of where the future lay, said Changbae Park, senior manager at product strategy team of the VD business.

Just a few years ago, the South Korean tech giant was heavily promoting OLED (organic light-emitting diode), butting heads with compatriot LG Electronics. It seemed OLED would be the next fight between the Koreans in their half-century-long rivalry in TVs.







Until Samsung introduced QD LCD TVs, that is. Put simply, a QD film is layered on the LCD that enhances the colour accuracy and range. Samsung began researching the core technology of QD materials 10 years ago with display applications in mind. But while Sony gave up on QD LCD in 2013 due to the need to use cadmium, which is harmful to humans, Samsung managed to overcome this. (Sony also gave up on OLED in 2010 after being the first to introduce an OLED TV in 2007.)

"We concluded that OLED was a dead-end," said Park. "There were a lot of fundamental problems with OLED, such as the burn-in, especially for over 65-inch large size TVs, which is difficult to overcome, and a limited brightness that's inadequate for HDR (high dynamic range).

"The choice was neither easy nor difficult. It was just an inevitable, logical choice on our part, if you consider what the consumers would want," the senior manager said. "I can categorically say that we do not plan to shift back to OLED. As a leader, it is not a responsible choice. Not now or in the future."

OLED uses organic materials that fundamentally limit the display's lifespan and causes burn-in, Park said. "Ask any retailers about burn-ins, and they will know."

Conversely, QLED uses inorganic materials that are more stable, meaning it doesn't have this problem. "We believe, ultimately, that the so-called OLED camp will, in the end, move towards QLED, and follow our lead," Park added.

The latest curved QLED TV. Flat-panel display technology has done wonders for TV designs.

"Internally, we have a roadmap. I don't want to say when, but we are heading towards an even more sophisticated technology with self-light-emitting quantum-dot diode. It will most likely be faster than people think it will be." Backlight will be removed and the QD material will emit light on its own.

Curious how recently this statement was made, but I gotta say that I question Samsung leadership after making such a statement. Simply because it is more rational and responsible to never say never. I guess Apple said the same thing once and they are obviously coming around to OLEDs . The technological hurdles have been overcome and it appears OLEDs time is now. Park is living in the past and could be sacrificing the future of his company just so he doesn't have to admit his company's inability to commercialize large format OLEDs . "Pride goeth before a fall. "

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.
