Nanomaterials and quantum dot scientist and consultant, Pete Palomaki and co-author Matthew Bertram explain how different display nanotechnologies work in their latest blog post.
Bob Myers, writing for Android Authority, talks about the promising future of Quantum Dots for displays and how the technology can truly be a quantum leap for the display industry.
"It wouldn’t be at all surprising if quantum-dot displays — both LCD-based and those using QDs as basic emissive elements — become dominant across the electronic display industry in relatively short order. It’s actually quite possible that OLEDs, once hailed as the next big technology, could be bypassed without ever getting close to a majority share in the market.
Truly, a quantum leap for the industry."
The latest issue of IEEE Spectrum features an in-depth article, co-authored by Nanosys, on the exciting roadmap for Quantum Dot technology in displays. From enhancing LCDs to microLED integration to low cost, printed and flexible Quantum Dot displays, it's all here:
The future of the television set was supposed to be simple. At some point in the near future, LCDs were supposed to become obsolete and give way to bright, sharp, and incredibly thin OLED displays. It turns out that the near future of TVs isn’t going to be so simple—but it sure is going to be bright.
The reason? Quantum dots.
The Quantum Dot market will reach $16.6 Billion by 2028 according to a new report by Dr. Jennifer Colegrove of Touch Display Research:
“The quantum dot industry changed dramatically in 2017. Samsung/Harman is expanding QLED to automotive application. Apple just entered quantum dot market. We forecast quantum dot industry will have rapid growth in the next several years.”
According to the IHS market, the large TFT display market grew significantly in 2017, reaching $63.7 billion in revenue. Thanks to increasing demand for large displays and high end products such as Quantum Dot displays, the market expanded in all three aspects -- unit shipments, area shipments and revenue. Robin Wu, principal analyst at IHS Markit:
"Revenue growth was higher than that of area shipments, which was again bigger than that of unit shipments. This indicates that the display market is moving to larger screens in all applications, and the penetration of high specification products with a higher price tag, such as high resolution, wide viewing angle and slim design panels, has increased.”
Nanosys VP of R&D Dr. Charlie Hotz will be speaking at the 2018 Quantum Dot Forum in San Diego this March. In a recent interview with the show organizers, Dr. Hotz discusses the future of Cadmium free quantum dot technology.

Ken Werner, writing for DisplayDaily, talks about Harman's new innovative use of quantum dot displays for high end automotive applications. In a CES 2018 demonstration, a QLED quantum dot display was paired with an OLED display inside a dark Maserati and the QLED display with local dimming did not show any sign of visual mismatch against the OLED.
"Rashmi Rao, Harman Senior Director of Advanced Systems and User Experience, explained that for a high-end car like the Maserati, Harman selected the best-performing display technology for the critical instrument cluster, while the large QLED display still offers very good performance at a significantly lower cost than OLED. Rao commented that the QLED does a good job of integrating visually with the OLED. A conventional LCD would present an obvious visual mismatch with the OLED. The system in the Maserati was fully functional but is not yet in a shipping automobile."
If I seem excited about quantum dots, it's because I am. This is a fascinating and cool technology that could radically improve the picture quality of TVs. Beyond Samsung, other TV manufacturers like TCL and Hisense sell quantum dot models now, and Sony, LG and others have sold them in the past. I expect the trend to continue in the future.
Nanosys will be on-hand with demos of our next-generation Quantum Dot materials from QDEF to QLED. Contact us to set up a time for a demonstration.
Chris Chinnock, writing for DisplayDaily, looks at how HDR is not only establishing itself in the TV market but now also the PC monitor market. Multiple technologies are coming together to make this happen. On the software side, emerging support for Nvidia's G-Sync HDR and AMD's FreeSync 2 technologies have helped to fix the problems of the poor support of HDR by Windows 10. At the same time, Quantum Dot technology is enabling a majority of HDR monitors on the market today to deliver a great experience with rich color and high brightness.
Stephan Jukic from 4K.com talks about how Nanosys Electro Luminescent Quantum Dots has to potential to crush OLED TVs and other devices.
"Nanosys calls this technology Electro Luminescent Quantum Dot display (ELQD) and it believes that their development will completely disrupt the current television display industry, in which OLED dominates as far as sheer advancement goes.
These new ELQD displays will in fact work a bit like OLED screens in that they won’t require a backlight of any kind but they’ll create a further advantage due to their superior color palette creation ability –to a degree even higher than that achievable by OLED. At the same time, because each QD subpixel inside such screens will be capable of individual activation/deactivation, ELQD screens will deliver the same perfect blacks, pixel-perfect local dimming and wide viewing angles as those achieved by OLED screens today. Another benefit of such pixel luminance efficiency would be lower overall power consumption, since relatively inefficient, broadly luminous LED backlights can (literally) be removed from the picture.
Taiwanese tech magazine, Circuit Cellar, looks at how next-generation electroluminescent Quantum Dot technology can fulfill the promise of OLED:
[Translation] While OLED is still working to push their blues to the required level, quantum dot technology has already proven that it is a better luminescent material for this application. Unlike OLED, quantum dots can produce the required blue light without any physical limitations. Also, quantum dots are made of durable inorganic material to provide better stability under oxygen and water vapor. [...]
This technology may take up to three to five years to commercialize. Nanosys is currently working on reducing the cost and finding a way to make it compatible standard materials. To achieve this, Nanosys will not be using the standard semiconductor manufacturing process for this application and instead, they will be using inkjet-printing.”
Scott Wilkinson of AVSForum posted a great write-up this week on the news about Nanosys and DIC's breakthrough for inkjet-printed Quantum Dot color conversion devices:
"Color-filter replacement (CFR), also known as color conversion, offers many benefits. Among them is greater power efficiency, which translates to as much as 300% higher brightness. Other benefits include a wider color gamut and 180-degree viewing angle.
Inkjet-printed quantum dots will also hasten the development of electro-emissive QD displays, in which quantum-dot subpixels emit light directly under electrical stimulation—no backlight needed. This is still a few years away from commercialization, but the Nanosys/DIC announcement paves the way for this exciting development."
As more and more devices and display support HDR, consumers are looking for sources of content that deliver the full HDR experience with wide color gamut and deep contrast. Popular video sharing platform Vimeo has announced that it will be allowing all members to upload HDR videos to the platform and sell those videos through Vimeo On Demand or with a custom subscription-based model. Aside from HDR, Vimeo is also going to support 10-bit video and wide color gamut through the REC. 2020 support.
Jeff Yurek, Nanosys Director of Marketing, recently joined Comcast Bay Area's Advanced Broadcast Technology show to give a talk on Quantum Dots and metrology for wide color gamut displays. Why does Wide Color Gamut matter? Jeff analyses a mechanism of Color and the Human Visual System and talks about measuring color for displays.

Nanosys executives caught up with IEEE Spectrum during the Economist's Future Materials Summit earlier this month for a conversation on the future of printed Quantum Dot displays:
“If we can get the cost of making a display down to $100 per square meter, which is basically the same cost as printing a high-reolution poster or printing a T-shirt, then displays could be everywhere,” said Russell Kempt, vice president of sales and marketing at Nanosys. “That’s our vision and we believe that the quantum dot material is the only material that has the opportunity to achieve this.”
Sweta Dash from DisplayDaily explains how Quantum Dots are enabling LCDs to match or even out perform competitors by providing higher peak brightness, wider color gamut and better image quality. These are all the crucial requirements for the best UltraHD HDR experience:
"After CCFL-based TV sets reached market maturity and growth slowed down, LED-based LCD TV created a growth cycle by boosting replacement demand. The winning formula was “good enough picture quality” with “competitive price”. It not only changed the TV market, it also spilled over to all other application markets such as monitor, notebook, industrial, medical and others and that strengthened the LCD technology and production base. Quantum dot technology has the same potential to enable LCD to create a growth cycle and drive replacement demand.
TV manufacturers are shifting to higher resolutions to offer better picture quality. But adoption of WCG and HDR with 4K resolutions really helped consumer to see the visual quality differences and experience it. Quantum dot enhanced backlight light in LCD TV takes it to the next level with an even wider range of colors and luminance."
Learn about the latest Quantum Dot technology with David Savastano at Printed Electronics Now as he interviews Russell Kempt, Nanosys VP of Sales and Marketing:
There has been a lot of discussions over the years about both flexible displays and the possibility of printing these displays. Leaders in the quantum dot field say that both of these scenarios are strong possibilities.
“Quantum dots can absolutely be deployed in flexible displays,” said Nanosys’ Kempt. “In fact, all of the research we are doing today for flexible displays relies on printing techniques. Nanosys is leading the way in the development of EL QD displays. We have already achieved better than 10% external quantum efficiency (EQE) for our blue cadmium free EL-QD emitter materials. This is a key milestone in the development of EL QD displays. For context, the best commercially available blue OLEDs are not much better. However, there is more work to do before EL QD displays are fully commercialized. We expect to see displays in the three- to five-year time frame.”
