Nanosys, the Milpitas company which is one of the two leading producers of quantum dots, says that TVs with the technology can produce 50 percent more colors than typical LCD sets. LCD TVs have generally struggled to reproduce the range of colors in the standard spectrum used for years in broadcast television; with quantum dots, they have the potential to display nearly all of the colors in the much wider next-generation standard for broadcasting, experts say.
As in past years, TVs—especially 4K UHD TVs—commanded a lion's share of the attention at CES 2015, thanks to promised improvements in TV performance beyond pure resolution. Among the highlights were new TVs boasting quantum dot technology, which can purportedly improve color beyond what we get today.
Makers are ramping up production
SANTA CLARA, CALIF.— Quantum dot TVs are coming on strong, according to DisplaySearch. LCD TVs, using quantum dot technology will become available this year, DisplaySearch said, with 1.3 million shipping worldwide. Shipments of quantum dot TVs are expected to grow to 18.7 million in 2018.
“The launch of new 4K UHD services promises to foment another round of innovation, as content creators bring richer, deeper colors to their art,” said Paul Gray, director of European research at DisplaySearch. “Curved screens are also a popular feature this year, but there will be limited opportunity for growth, as the market for this feature is expected to peak next year.”
If you look at the CES 2015 word cloud—a neon blob of buzz radiating from the Nevada desert, visible from space—much of it is a retweet of last year’s list. Wearables. 4K. The Internet of Things, still unbowed by its stupid name. Connected cars. HDR. Curved everything. It’s the same-old, same-old, huddled together for their annual #usie at the butt-end of a selfie stick.
But there at the margin, ready to photobomb the shot, is the new kid: quantum dot. It goes by other names, too, which is confusing, and we’ll get to that in a minute. Regardless of what you call it, QD was all over CES this year, rubbing shoulders with the 4K crowd. You may have heard people say it’s all hype. Those people can go pound sand. Quantum dot is gonna be the next big thing in TVs, bringing better image quality to cheaper sets.
At the 2015 CES show, Samsung and LG jumped aboard the quantum dot bandwagon, and even experienced broadcasters came away impressed with the brightness, contrast, clarity and color saturation of these displays. So what is quantum dot and what does it mean to viewers and broadcasters?
LAS VEGAS—The world’s top television makers will this year peddle sets that enhance the color representation of their screens, but postpone a more dramatic shift in technology that promised thinner frames, more energy efficiency and crisper images.
New TVs and prototypes featuring “quantum dot” technology from manufacturers in South Korea, China and Japan took center stage at the Consumer Electronics Show in Las Vegas last week, where companies including Samsung Electronics Co. and LG ElectronicsInc. showed off videos with vibrant color.
Samsung's latest SUHD TVs feature Quantum Dot technology licensed from Nanosys. Some of the awards include:
- Samsung’s JS9500 TV which received more than eight awards including Ubergizmo’s Best of CES award, Digital Trends’ Best Television at CES 2015 award and Reviewed.com’s 2015 CES Editors’ Choice award.
- Samsung’s 105-inch UN105S9B TV, the World’s First and Largest Bendable SUHD TV, earned a CES award for Best of Innovation: Video Displays.
Samsung unveiled its stunning S’UHD technology at its keynote this year, but it took legendary designer Yves Behar to help make it an 82-inch reality. With a 21:9 aspect ratio, the S9W is wider than most every TV on the market today, and the difference shows immediately. It rests on an illuminated cube that provides audio and lets you swivel the entire TV. Sadly, Samsung didn't let Behar design the name as well, but this is still the closest a TV has gotten to being a work of art.
Because of the Quantum Dot technology in the panel, the JS9500 boasts roughly 20-30% more color than a standard HDTV. This is the kind of image improvement that's especially hard to quantify with words—seeing is really the best option. Suffice it to say the intensity of the colors leaves a lasting impression.
According to Samsung, the JS9500 is capable of about 92% of the DCI P3 color space, meaning it easily exceeds the color abilities of traditional, non-Quantum Dot HDTVs.
If you happened to pay attention to the technology news coming out of the International CES last week, you might have heard that the TV makers introduced their latest and greatest TVs — 4K, SUHD, OLED and LCD — with quantum dot or nanocrystal display technology.
I’m with you. The new displays shown off at CES were impressive, but their descriptions bordered on ridiculous. Unless you have an advanced degree in quantum physics, you’ll likely be in one of two categories of TV-buying consumers in the coming months: One who casually boasts to his friends that he’s got a “quantum dot TV,” without having any actual understanding of it; or one who stands in front of the shelves at Best Buy, befuddled about what it all means.
Samsung is serious with a capital 'S' when it comes to its 2015 4K lineup. Dubbed SUHD, Samsung's best efforts for 2015 bring quantum dot technology for better color and brightness, an entirely new aesthetic, and an overhauled smart TV/user interface based on the Tizen operating system.
In the newly published “Quantum Dot Display and Lighting Technologies and Market Forecast Report” Second Edition, Touch Display Research surveyed many quantum dot suppliers and found that the quantum dot display component market is gaining momentum. Touch Display Research forecasts that the quantum dot display and lighting component market will surpass $2 billion by 2016 and reach $10.6 billion by 2025. This report profiles over sixty companies working on quantum dot materials and quantum dot components.
“Quantum dot technology could improve Liquid Crystal Display (LCD) dramatically in terms of color gamut, color accuracy, and reducing power consumption. This is one of the biggest breakthrough technologies for LCD in recent several years. Cadmium-free quantum dot is entering the market in 2015,” said Dr. Jennifer Colegrove, CEO and principal analyst of Touch Display Research Inc. “We forecast quantum dot components will have a rapid penetration into displays and lighting from 2015 to 2025.”
Berkeley Lab’s nanotechnology enlivens Nanosys’ displays, enhancing the color and saving energy.
Outside his career as a noted nanochemist, Lawrence Berkeley National Laboratory (Berkeley Lab) director Paul Alivisatos is an avid photographer. To show off his photos, his preferred device is a Kindle Fire HDX tablet because “the color display is a whole lot better than other tablets,” he says.
What he may neglect to mention to the viewer is that not only did he take the photograph, he also helped invent the nanotechnology allowing the viewer to see those brilliant greens, rich reds, and bold blues, all while using significantly less energy. In fact, the Kindle display utilizes a technology manufactured by Nanosys, a startup Alivisatos cofounded in 2001 to commercialize quantum dots.
A major trend in TV this year is the increasing commoditization of UHD (4K) TV. The speed with which 4K has gone from expensive to cheap continues to surpirse many people in the industry. If last year was the year of UHD-TV's breakout, this year will surely be the year of quantum-dot-enhanced TV. Many major manufacturers announced QD-enhanced TVs for release this year, including Samsung, LG and TCL. Unfortunately, they will probably be called "QD-TVs." But if we can survive "LED TVs," we can probably survive "QD-TV", too.
Viewed side by side with conventional LCD-TVs, the increased color saturation and gamut produced by QDs provide an obvious improvement in image quality and allow TV makers to exceed 90% of REC.2020. Combined with 4K, QDs produce really compelling images. Samsung went so far as to say that QD enhancement provides image quality that is superior to OLED.
If you’ve been paying attention to the market for TVs over the last few months, and especially during CES this week, you’ve been hearing a lot about 4K and 8K. But the real action today, and going forward, is in quantum dots.
Known alternately as QDots or nanocrystals, quantum dots are the foundation behind what is expected to be one of the biggest sea changes in the television market over the next few years.
A lighting technology that has been around since the 1990s, quantum dots have only recently started to gain currency with TV makers. But they may soon be the hottest thing in the high-end TV market given that they offer lower costs, higher energy efficiency, and better colors than competing technologies, experts say
Multi-year agreement covers broad range of quantum dot patents
Nanosys, the Milpitas, California-based quantum dot maker, has announced that it has entered into a multi-year patent license agreement with Samsung Electronics.
Under the agreement, Samsung will gain access to Nanosys’ quantum dot patents covering a broad range of lighting and display products and technologies, including cadmium free quantum dots.
Samsung first partnered with Nanosys four years ago to develop a new generation of quantum dot technology, which enables displays to deliver brighter, more lifelike colors while using less power. Samsung now introduces new era of TV using Quantum Dot technology.
“As the world’s most efficient light emitting technology, Quantum Dots are poised to change the way we see displays,” said Jason Hartlove, president and CEO, Nanosys, Inc. “We are extremely pleased to continue our strong relationship with Samsung, to support them with new technologies as they continue to develop and introduce exciting Quantum Dot display products to the marketplace.”
“Quantum dots could improve LCDs dramatically in terms of colour gamut, colour accuracy and reducing power consumption. This is one of the biggest breakthrough technologies for LCD in the last several years.” said Jennifer Colegrove, CEO and Principal Analyst, Touch Display Research. “We forecast the quantum dot display and lighting component market will reach $9.6 billion by 2023.”
The day before the annual International Consumer Electronics Show in Las Vegas (informally known as press day) is traditionally the time for the large, established consumer electronics manufacturers to strut their stuff. And because these are the outfits that own the factories that make the video screens for gadgets big and small, you know they are going to talk about TV, their flagship product.
"Quantum Dot" is one of the major buzzwords at CES 2015 and Nanosys Quantum Dot technology powers several stunning TVs at the show. Here's where you can find our tech if you're at CES this week:
Hisense 4K ULED TV
TCL Local Dimming 4K TV
Changhong Theater Quality TV
Samsung has presented the first SUHD TV with the best picture quality ever produced for an LCD-based television. Next level of the picture quality is achieved thanks to quantum dot nano crystal semiconductor technology which allows to create displays with more colors than standard LCD displays.
As a result of implementing the new technology, the TV picture becomes brighter, colors have better accuracy and higher saturation. Samsung says its SUHD sets achieve up to 2.5 times the light output of standard LED LCDs.
So what is the difference between a usual LCD TV and SUHD TV? And how does quantum dot nano crystal technology work?
