Quantum Dot Makers Defy Conventional Wisdom

It has become conventional wisdom that the two major quantum-dot display-enhancement approaches — the flattened glass cylinder of QD Vision and the polymer sheet of Nanosys/3M — have there own natural market segments, and this conventional wisdom has been supported by statements from the two camps.

QD Vision’s “Color IQ” glass element, which is incorporated in Sony’s Triluminos color-enhancement system, grows linearly with screen diagonal. 3M’s Quantum Dot Enhancement Film, which can be substituted for the diffuser film in an LCD backlight, grows with the square of the screen diagonal. It seems logical that at a certain point the cost of QDEF for larger screens would significantly exceed that of the Color IQ element, so the natural market segment for Color IQ would be large screens and the natural segment for QDEF would be small and medium screens.

And that’s how things started out. QD Vision’s first major design win was in high-end Sony Bravia TV sets, and QDEF’s was in the Amazon Kindle Fire HDX 7.0 and 8.9 inch tablets, in which the QDEF increases the color gamut from 60% to 72% NTSC and enables a significant improvement in battery life.

But at CES HiSense introduced a UHD-TV quantum-dot “Wide Gamut TV,” which uses QDEF film rather than Color IQ. These sets, with a maximum size of 85 inches, will enter the Chinese market in March and the U.S. market this summer.

Vaio Pro Ultrabooks TriluminosThen, if you looked closely in the Sony booth, you could see VAIO Pro Ultrabooks and Flip PCs with Triluminos displays So much for conventional wisdom. Sony wasn’t making much fuss about the Triluminos displays in its high-end notebooks at CES, but the opposite is true on the Sony Store website. The Triluminos displays appear to be available on the 11.6- and 13.3-inch VAIO Pro Ultrabooks and on the 13.3-, 14-, and 15.5-inch Flip PCs. All of these displays are Full HD.  By the way, in addition to having a FHD Triluminos display, the Sony VAIO Flip sports a very clever slide-and-flip mechanism for converting between PC, tablet, stand, and easel configurations.

So, what has happened to change the conventional wisdom? Nanosys tells me that if all things were equal, the conventional wisdom might apply, but that QD Vision has to use a greater density of QDs than 3M does, so the cost difference in large screens is less than was originally anticipated. I do not yet have an answer for the opposite question: Why is it economical to use the Color IQ element for smaller screens? I hope that QD Vision’s Seth Coe-Sullivan will be answer that question at the SID Los Angeles Chapter’s One Day Symposium on Advanced Television Technologies being held February 7 at the Costa Mesa Country Club (http://www.sid.org/Chapters/Americas/LosAngelesChapter/Symposium.aspx). 3M’s Eric Joste will also be speaking. Gentlemen, now you know some of the questions we will be directing your way in Costa Mesa.

The RCA Brand Prospers

RCA, the iconic company that — more than any other — brought color television to the consumer mass market was dissolved years ago. But its brand has survived and sometimes prospered. The brand is owned and licensed by Technicolor. After some mis-steps in years past, Technicolor is now managing the brand in an intelligent and unusually hands-on fashion.

For the last four years, the brand has been licensed to the ON Corporation of Seongnam, Korea, which will continue to manufacture RCA TV sets for the U.S. and some other markets until at least 2020. ON has the license for TV production and distribution only, with other companies having the licenses for “video tablets,” telephones, and accessories. However, an indication of the way Technicolor is managing the brand could be seen in the RCA booth, which combined ON Corp’s RCA TVs, Digital Stream’s mobile RCA TVs, and Telefield’s RCA business telephones. If you didn’t know better, you might think that RCA still existed as a company.

ON Corp US positions its TV models on the value end of the spectrum, but not at the bottom of it. The sets don’t look cheap, and the design of the higher-end sets, with ultra-thin bezels, is attractive. RCA is entering the 4Kx2K (or Ultra HD) TV market this year with three screen sizes: 55, 65, and 84 inches. These sets have LED backlights and smart TV functions. The Android (formerly Google) TV platform built into each of the sets provides an integrated on-screen interface with access to cable/satellite TV, apps and online content, including more than 100,000 on-demand movies and TV episodes, and thousands of YouTube channels. The UHD-TV sets all have a native 4K resolution of 3840 x 2160.

“Our first Ultra HD TVs are priced very competitively because we anticipate 2014 to be a pivotal year for this new class of TVs as more consumers become exposed to the striking picture quality that is possible with virtually any source material,” said Jonathan Zupnik, ON Corp US Executive VP of Marketing.

Smart features include the Google Chrome web browser; Google’s PrimeTime guide, which permits browsing channels while streaming or watching live TV and recommends shows based on personal preferences; Google TV Search for quickly finding shows by title, channel name, actor, or genre; and voice search.

RCA says the higher-end sets have a “curved design,” but that refers to the curved-bar base, not to the screen. Zupnik said he did not anticipate people might think RCA was referring to a curved screen. Indeed, all of the RCA models have flat, rather than curved, screens. Zupnik said that ON Corp has built curved-screen sets but decided not to make them part of the U.S. line-up or to show them at CES. “I’m very cautious about curved screens,” Zupnik said.

The less expensive tier of RCA sets are HDTV rather than UHD-TV, and implement their smart TV features with a Roku Streaming Stick, which provides access to over a thousand entertainment channels. Some of the sets simply provide an exposed MHL port into which the Roku stick is inserted, but some come with the stick already installed in an MHL port that is concealed behind a simple screw-on panel. Screen sizes for the HDTV line-up run from 28 to 65 inches.

RCA is doing well, said Zupnik, with sales up over 20% in the last year. For an old RCA hand such as yours truly, it’s good to see the old brand prosper. This is surely not what General Sarnoff had in mind for his legacy, but it’s not nothin’ either.

Display Surprises at CES 2014

Some of my fellow analysts have been bemoaning a lack of TV, tablet, and cell-phone innovations at CES 2014. Well, either I have lower standards than my colleagues or a keener eye because I saw quite a few things that surprised, delighted, and horrified me. Here are some of them.

3M’s Quantum Dot Enhancement Film (QDEF) using quantum dots from partner Nanosys is now in a high-volume shipping product. 3M was coy about identifying the customer, but partner Nanosys (which supplies the quantum dots used by 3M) didn’t hesitate. QDEF is being used in Kindle Fire HDX 7.0 and 8.9 inch tablets. The 8.9-inch has a 2560×1600-pixel display withg 339 pixels per inch (ppi), and uses QDEF to increase the color gamut from 60% to 72% NTSC. This is a noticeable although not extreme improvement, but Amazon asked 3M and Nanosys to optimize the system to significantly improve battery life, even if that meant only a modest improvement in gamut. They did. Battery life is substantially improved.

xDSC_4814_

Plasma is not dead yet, despite Panasonic pulling the plug.  ChangHong will sell plasma TVs in the U.S. this year in 43-, 51-, and 60-inch sizes. LG says it will continue to sell plasma in 2014. If Samsung said anything, I missed it.

HiSense introduced a 4K quantum-dot “Wide Gamut TV,” which uses QDEF film rather than the QD Vision rail. It will enter the Chinese market in March; U.S. in the summer. Maximum size is 85 inches, and there is an H.265 decoder built in.

Professional high-dynamic-range technology at consumer prices? Sharp is working on it. We could see an HDR TV in 2015, a Sharp booth rep said. (Photo: Ken Werner)

In addition to the impressive AQUOS Quattron+, which I described at some length in a previous post (http://www.hdtvexpert.com/?p=3517), Sharp showed a a high-dynamic range TV prototype using Dolby technology. What’s surprising is that the highly effective Dolby technology has only been used until now for very expensive professional monitors. It would be impressive if Sharp can bring the technology’s cost down to high-end consumer levels. A Sharp rep said products could appear in 2015.

Samsung showed an OLED display that could be bent from flat to gently curved by small motors whirring away inside the case. Lots of oohs and aahs from the assembled. Is this good for anything? Beats me, but I did say this was going to be a list things that were surprising. That doesn’t mean useful.

xDSC_4472_

Horizontal tiling of curved displays provides the immersive feeling that single curved displays of modest size do not. This has real applications for digital signage. (Photo: Ken Werner)

Samsung and others did find ways to do something (potentially) useful with curved displays. The radius of curvature for curved TVs is so large (roughly 15 feet) that it really makes little sense for 55- and 65-inch screens. But Samsung extended the curve by tiling a bunch of these curved screens side to side. Definite applications for digital signage. LG showed a 105-inch curved display. At that size, the claim for curvature offering a more immersive viewing experience has credibility.

xDSC_4718_

LG Display’s curved 105-inch OLED-TV is big enough to provide the immersive experience that smaller curved displays do not. (Photo: Ken Werner)

WebOS may finally have found a reason for living as the OS for LG smart TVs. Of the 25 new TV models LG will introduce this year, 56% will have WebOS. Research shows most people think smart TV is too complicated, which inspired LG to position WebOS as the “intuitive OS optimized for the Web.”

Pixelworks has taken its motion-estimation and motion-compensation (MEMC) chip, which burns 5 watts in TV sets, and produced a very-low-power version for mobile devices. The TV version of the chip is in some LG sets now, and Skyworth has announced another design win for the chip. The video processing chip takes 24 frame-per-second (fps) content and and converts it to 120, thus producing a major improvement in judder. As we spend more time watching video on our small personal screens, we are likely to get impatient with the motion artifacts that have already been dealt with on our living-room TVs. A side-by-side demo in Pixelworks’ suite was impressive.

It may not be a surprise in principle, but actually seeing the combination of OLED and 4K is VERY impressive.

Not all 4K TVs are beautiful. The 55-inch S1 model from New Century Optronics was truly terrible, with serious comb artifacts (when was the last time you saw a comb artifact?), bad judder, and resolution that looked more like 2K than 4K. At least the U13 model looked like 4K, but it too exhibited serious judder.

Chinese OLED TVs in 2014. Chinese TV giant TCL showed 30.5-inch and 55-inch FHD OLED-TVs. The sets will be launched in China next month, and in the U.S. in Q2 or Q3. The 55-inch has a color gamut of 100% NTSC. A TCL rep said the OLED panel in the 30.5-inch is manufactured by TCL and the panel in the 55-inch is manufactured by a partner. That probably means that the 30.5-inch is produced by China Star Optoelectronics Technology (CSOT), which is a business unit of TCL.

LG Display’s OLED manufacturing yield to rise sharply. It is no secret that the manufacturing yields of LGD’s OLED TV panels were so low last year — estimates were between 10% and 30% — that they severely impacted the number of panels that could be produced and kept their cost high. Now, LGD executives tell me the internal yield target for the new OLED plant opening in Q3 is 75%.

Panasonic Lumix “hybrid photography.” Now that digital “still” cameras also capture motion video, manufacturers are trying to figure out what what they can do with this combination of abilities. Nikon 1 cameras can bracket a still photo with a short video clip. Panasonic’s “hybrid photography” may turn out to be more useful. It produces a largely still image with moving elements: among the demos was a woman’s still face with softly moving hair. The file should be only slightly larger than a traditional still shot, but still provide motion. We’ll see how consumers respond.

Perhaps I’m easily amused, but I left CES 2014 not only exhausted, but also convinced that there were lots of entertaining surprises to be sniffed out by display bloodhounds.

CES 2014 In The Rear-View Mirror

Once again, CES has come and gone. It sneaks up on us right after a relaxing Christmas / New Year holiday. We’re jolted out of a quiet reverie and it’s back to the rush to board at the airport gate, walking the serpentine lines for taxis at McCarran Airport, and “late to bed, early to rise” as we scramble to make our booth and off-site appointments in Las Vegas.

We don’t make them all on time. Some we miss completely. But there’s a serendipity angle to it all: We might find, in our haste to get from one meeting to another, some amazing new gadget we didn’t know about as we take shortcuts through booths in the North, South, and Central Halls.

Or a colleague sends us a text or leaves a voicemail, emphatically stating “you have to see this!” Or a chance meeting leads to an ad hoc meeting, often off-site or over a hasty lunch in the convention center.

My point is this: You “find” as many cool things at the show as you “lose.” For every must-see product that you don’t see, there’s another one you trip over. Granted; many “must-see” products are yawners – you’ve figured it out 30 seconds into your carefully-staged meeting with PR people and company executives, and you’re getting fidgety.

My best CES discoveries involve products or demos where I can observe them anonymously, without PR folks hovering at my side or staring at my badge before they pounce like hungry mountain lions.

Unlike most of my colleagues in the consumer electronics press, I don’t need to break stories the instant I hear about them. There are already too many people doing that. What’s missing is the filter of analysis – some time spent to digest the significance of a press release, product demo, or concept demo.

And that’s what I enjoy the most: Waiting a few days – or even a week – after the show to think about what I saw and ultimately explain the significance of it all. What follows is my analysis of the 2014 International CES (as we are instructed to call it) and which products and demos I thought had real significance, as opposed to those which served no apparent purpose beyond generating daily headlines and “buzz.”

Curved TV screens: OK, I had to start with this one, since every TV manufacturer at the show (save Panasonic and Toshiba) exhibited one or more curved-screen OLED and LCD televisions. Is there something to the curved-screen concept? On first blush, you’d think so, given all of the PR hype that accompanied these products.

The truth is; really big TV screens do benefit a little from a curved surface, particularly if they are UHDTV models and you are sitting close to them. The effect is not unlike Cinerama movie screens from the 1950s and 1960s. (That’s how I saw Dr. Zhivago and 2001: A Space Odyssey back in the day.)

Toshiba described their version of the 21:9 widescreen LCD TV as having "5K" resolution - and mathematically, it does (I guess!).

This wall of 56-inch curved OLEDs greeted visitors to the Panasonic booth.

Bear in mind I’m talking about BIG screens here – in the range of 80 inches and up. The super-widescreen (21:9 aspect ratio) LCD TVs shown by Samsung, LG, and Toshiba used the curve to great effect. But conventional 16:9 TVs didn’t seem to benefit as much, especially in side-by-side demos.

The facts show that worldwide TV shipments and sales have declined for two straight years, except in China where they grew by double digits each year. TV prices are also collapsing – you can buy a first-tier 55-inch “smart” 1080p LCD TV now for $600, and 60-inch “smart” sets are well under $800 – so manufacturers will try anything to stimulate sales.

Is that the reason why we’re seeing so many UHDTV (4K) TVs all of a sudden? Partially. Unfortunately, there’s just no money in manufacturing and selling 2K TVs anymore (ask the Japanese manufacturers how that’s been working for them), and the incremental cost to crank out 4K LCD panels isn’t that much.

Chinese panel and TV manufacturers have already figured this out and are shifting production to 4K in large panels while simultaneously dropping prices. You can already buy a 50-inch 4K LCD TV from TCL for $999. Vizio, who is a contract buyer much like Apple, announced at the show that they’d have a 55-inch 4K LCD TV for $1299 and a 65-inch model for well under $2,000.

Hisense is building a factory in the U.S. to assemble TVs. And you wondered if they were serious about the North American TV business?

Vizio's 65-inch high dynamic range (HDR) 4K TV was very impressive.

Vizio’s 65-inch high dynamic range (HDR) 4K TV was very impressive.

Consider that the going price for a 55-inch 4K “smart” LCD TV from Samsung, LG, and Sony is sitting at $2,999 as of this writing and you can see where the industry is heading. My prediction is that all LCD TV screens 60 inches or larger will use 4K panels exclusively within three years. (4K scaling engines work much better than you might think!)

And don’t make the popular mistake of conflating 4K with 3D as ‘failed’ technologies. The latter was basically doomed from the start: Who wants to wear glasses to watch television? Not many people I know. Unfortunately, glasses-free (autostereo) TV is still not ready for prime time, so 3D (for now) is basically a freebie add-on to certain models of televisions.

4K, on the other hand, has legs. And those legs will get stronger and faster as the new High Efficiency Video Codec (HEVC) chips start showing up in televisions and video encoders. HEVC, or H.265 encoding, can cut the required bit rate for 2K content delivery in half. That means it can also deliver 4K at the old 2K rates, somewhere in the ballpark of 10 – 20 Mb/s.

Toshiba (like many others) is moving quickly to adopt and integrate HEVC H.265  encoding and decoding into their products.

While consumer demand for 4K is slowly ramping up, there is plenty of interest in UHDTV from the commercial AV sector. And Panasonic focused in on that sector almost exclusively in their CES booth. I’m not sure why – there are plenty of inferences here; most significantly, it would appear that Panasonic is exiting the money-losing television business entirely. (Ditto nearby Toshiba, which had similar 4K “applications” showcased and which also did not exhibit a line of 2014 televisions.)

Long story short; you may be buying 4K televisions in the near future whether you want ‘em or not. It’s a manufacturing and plant utilization issue, and if commercial demand for 4K picks up as expected, that will drive the changeover even faster.

As for sources of 4K content; Samsung announced a partnership with Paramount and Fox to get it into the home via the M-Go platform. Comcast had an Xfinity demo for connected set-top-boxes to stream 4K, and of course Netflix plans to roll out 4K delivery this year direct to subscribers.

I’m not sure how they’ll pull that off. My broadband speeds vary widely, depending on time of day: I’m writing this at noontime and according to CNET’s Broadband Speed Test, my downstream bit rate is about 22 megabits per second (Mb/s). Yet, I’ve seen that drop to as low as 2 – 3 Mb/s during late evening hours, when many neighbors are no doubt streaming Netflix movies.

Even so, HEVC will definitely help that problem. I spoke to a couple of Comcast folks on my flights out to and back from CES, and they’re all focused on the bandwidth and bit rate challenges of 2K streaming, let alone 4K. More 4K streaming interface products are needed, such as Nanotech’s $300 Nuvola NP-H1, which is about the size of an Apple TV box and ridiculously simple to connect and operate.

nVidia built an impressive 3D heads-up display into the dash of a BMW i3 electric car.

Oh, yeah. I should have mentioned organic light-emitting diode (OLED) displays earlier. There were lots of OLED displays at CES, ranging from the cool, curved 6-inch OLED screen used in the new LG G-Flex curved smartphone to prototype 30-inch OLED TVs and workstation monitors in the TCL booth and on to the 55-inch, 65-iunch, and even 77-inch OLED TVs seen around the floor. (LG’s 77-inch offering is current the world’s largest OLED TV, and of course, it’s curved.)

OLEDs are tricky beasts to manufacture. Yields are usually on the low side (less than 25% per manufacturing run) and that number goes down as screen sizes increase, which explains the high prices for these TVs.

And there’s the unresolved issue of differential color aging, most notably in dark blue emitters. With current OLED science, you can expect dark blue emitters to reach half-brightness at about 5,000 hours of operation with a maximum brightness of 200 nits. Samsung addresses this quandary by employing two blue emitters for every red and green pixel on their OLED TVs, while LG has the more difficult task of managing blue aging in their white OLED emitters.

Several studies over the past three years consistently show people hanging on to their flat screen TVs for 5 to 7 years, which is likely to be a lot longer than 5,000 hours of operation. Will differential color aging rear its ugly head as early adopters shell out close to $10K for a 55-inch OLED TV? Bet on it.

Turns out, there’s another way to get wide color gamuts and saturated colors: Quantum dots. QDs, as we call them, are inorganic compounds that exhibit piezoelectric behavior when bombarded with photons. They emit stable, narrow-bandwidth colors with no drift, and can do so for long periods of time – long enough to work in a consumer television.

3M featured its quantum dot film (QDF) in several demos. An LCD TV equipped with it is at the top of the picture.

This prototype WiHD dongle turns any smartphone or tablet equipped with MHL or Micro HDMI interfaces into a 60 GHz wireless playback system.

QDs are manufactured by numerous companies, most notably Nanosys and QD Vision in the United States.  The former company has partnered with 3M to manufacture an optical film that goes on the backside of LCD panels, while the latter offers Color IQ optical components that interface with the entire LED illumination system in edge-lit TVs.

Sony is already selling 55-inch and 65-inch 4K LCD TVs using the Color IQ technology, and I can tell you that the difference in color is remarkable. Red – perhaps the most difficult color to reproduce accurately in any flat-screen TV – really looks like red when viewed with a QD backlight. And it’s possible to show many subtle shades of red with this technology.

All you need is a QD film or emitter with arrays of red and green dots, plus a backlight made up of blue LEDs. The blue passes through, while the blue photons “tickle” the red and green dots, causing them to emit their respective colors. It’s also possible to build a direct-illumination display out of quantum dots that would rival OLED TVs.

How about 4K display interfaces? By now, you’ve probably heard that HDMI has “upgraded” to version 2.0 and can support a maximum data rate of 18 gigabits per second (GB/s).  Practically speaking; because of the way display data is transmitted, only 16 Gb/s of that is really available for a display connection. Still, that’s fast enough to show 4K content (3840×2160, or Quad HD) with a 60 Hz frame rate, using 8-bit color.

DisplayPort can now carry USB 3.0 on its physical layer. Here's an Accell DockPort breakout box with Mini DisplayPort and USB connections.

Epson's Moverio glasses aren't as sexy as Google Glass - but then, they can do more things.

Epson’s Moverio glasses aren’t as sexy as Google Glass – but then, they can do more things.

Over at the DisplayPort booth, I heard stories of version 1.3 looming later this spring. DisplayPort 1.2, unlike HDMI, uses a packet structure to stream display, audio, and other data across four scalable lanes, and has a maximum rate of 21.6 Gb/s – much faster than HDMI. Applying the “20 percent” rule, that leaves about 17.3 Gb/s to actually carry 4K signals. And the extra bits over HDMI means that DP can transport 3840×2160 video with a frame rate of 60 Hz, but with 10-bit color.

Don’t underestimate the value of higher data rates: 4K could turn out to be a revolutionary shift in the way we watch TV, adding much wide color gamuts, higher frame rates, and high dynamic range (HDR) to the equation. HDMI clearly isn’t fast enough to play on that field; DP barely is. Both interfaces still have a long way to go.

So – why not make a wireless 4K connection? There were plenty of demos of wireless connectivity at the show, and I’m not just talking about Wi-Fi. Perhaps the most impressive was in the Silicon Image meeting room, all the way at the back of the lower South Hall, near the Arizona border.

SI, which bought out wireless manufacturer SiBEAM a few years ago, demonstrated super-compact 60 GHz wireless HDMI and MHL links using their UltraGig silicon. A variety of prototype cradles for phones and tablets were available for the demo: Simply plug in your handheld device and start streaming 1080p/60 video to a nearby 55-inch LCD TV screen.

Granted, the 60 GHz tech is a bit exotic. But it works quite well in small rooms and can take advantage of signal multipath “bounces” by using multiple, steerable antenna arrays built-in to each chip. And it can handle 4K, too – as long as the bit rate doesn’t exceed the HDMI 2.0 specification, the resolution, color bit depth, and frame rate are irrelevant.

This sort of product is a “holy grail” item for meeting rooms and education. Indeed; I field numerous questions every year during my InfoComm wireless AV classes along these lines: “Where can I buy a wireless tablet dongle?” Patience, my friends. Patience…

You can now buy the concave-surface LG G-Flex smartphone. But you won’t see any of these in the near future…

The decline in TV shipments and sales seems to be offset by a boom in connected personal lifestyle and health gadgets, most notably wristbands that monitor your pulse and workouts. There were plenty of these trinkets at the show and an entire booth in the lower South Hall devoted to “digital health.”

Of course, the big name brands had these products – LG’s LifeBand was a good example. But so did the Chinese and Taiwanese manufacturers. “Digital health” was like tablets a few years back – so many products were introduced at the show that they went from “wow!” to “ho-hum” in one day.

This boom in personal connectivity extends to appliances, beds (Sleep Number had a model that can elevate the head of the bed automatically with a voice command), cars (BMW’s i3 connected electric car was ubiquitous), and even your home. Combine it with short-range Bluetooth or ZigBee wireless connectivity and you can control and monitor just about anything on your smartphone and tablet.

Granted; there isn’t the money in these small products like there used to be in televisions. But consumers do want to connect, monitor, and control everything in their lives, and their refrigerators, cars, beds, televisions, percolators, and toasters will be able to comply. (And in 4K resolution, too!)

Obviously, I didn’t visit the subjects of gesture and voice control. There were several good demos at the show of each, and two of the leading companies I showcased last year – Omek and Prime Sense – have been subsequently acquired by Intel and Apple. Hillcrest Labs, PointGrab, and other had compelling demos of gesture control in Las Vegas – a subject for a later time.

Summing up, let’s first revisit my mantra: Hardware is cheap, and anyone can make it. Televisions and optical disc media storage are clearly on the decline, while streaming, 4K, health monitoring, and wireless are hot. The television manufacturing business is slowly and inexorably moving to China as prices continue their free-fall.

The consumer is shifting his and her focus to all the devices in the home they use every days; not just television. Connectivity is everything, and the television is evolving from an entertainment device into a control center or “hub” of connectivity. The more those connections are made with wireless, the better – and that includes high-definition video from tablets and phones.

It’s going to be an interesting year…

 

 

 

 

 

 

 

 

 

 

At CES, Sharp Calls Its Quattron+ Almost-4K TV a “Game Changer”

At Sharp’s pre-CES press conference, held at the Mandalay Bay Hotel in Las Vegas on the morning of January 6, Sharp announced a television technology that John Herrington, president of the Sharp Marketing Company of America, called a “game changer.”

Unlike many of the products announced at CES, Quattron+ is a solution to a problem that actually exists. It enables an almost-4K viewing experience at prices that are roughly half those charged for true 4K TVs, according to Jim Sandusky, Sharp’s senior VP for U.S. product marketing. Sharp is calling the technique by which Quattron+ does this “Revelation Technology.”

Although no serious attempt was made at the press conference to explain how Revelation Technology allows an FHD Quattron screen to produce a near-4K image, Sharp’s Yoshida Yasuhiro and colleagues explained the underlying technology in detail at the LatinDisplay/IDRC 2010 conference held in Sao Paulo, Brazil, where their presentation won the Best Paper Award sponsored by the Brazilian Association for Informatics (ABINFO). Briefly, because a Quattron pixel contains four colored sub-pixels (red, green, blue, and yellow) it can produce any color by mixing the sub-pixel colors in two or more ways. This redundancy can be used to produce two luminance peaks per pixel instead of one, as is the case with typical LCDs for television, which use only three sub-pixels (red, green, and blue) per pixel.

The traditional Quattron pixel structure is a sequence of red, green, blue, and yellow vertical stripes. Last year at CES, Sharp showed a panel with this structure that produced two peaks per pixel in the horizontal direction, which allowed a 1920×1080-pixel panel to produce an effective resolution of 3840×1080 pixels. The image was considerably sharper than that on an adjacent, conventional FHD panel, but the demonstration was tucked away in the booth. If you weren’t looking for it, you probably wouldn’t have seen it or understood what you were seeing.

This year, it’s a different story, both from the technical and marketing perspectives. In addition to generating the two luminance peaks per pixel horizontally, the Revelation Technology splits each R,G,B, and Y sub-pixel vertically and addresses them such that the image is now essentially 3840×2160 pixels, or 4K. Quattron+ TV sets were prominently featured in Sharp’s booth on the CES show floor, and will be availailable later this year as part of the company’s 2014 line-up. Let’s be clear. These sets look very, very good, and it would take educated eyes to tell the difference between Quattron+ and true 4K, especially at typical living-room viewing distances.

Can Sharp do more with Quattron+ ? They can. Sources tell me that at CES 2015 we should look for 4K panels that use Revelation Technology to deliver 8Kx4K images.
