Overheard on the show floor, at the end of Day 3: “Why do I have to come back to Las Vegas every year? I didn’t do anything wrong.”
This year’s CES was one of the earliest I’ve attended, starting right after the first of the year with two days of press conferences (I attended just one) and four days of exhibits (three days were plenty for me), scattered all over Las Vegas from the main convention center to the Sands Expo Center, the Venetian Hotel, The Mandalay Bay, and numerous other off-site meeting places.
Turnout according to the CTA was strong, exceeding 160,000. And the exhibit halls were full up. Automobile manufacturers and audio companies camped out in the north hall, while the big names in consumer electronics staked their claims in the center hall, leaving the upper and lower south hall exhibit spaces to drones and VR brands, along with a slew of Taiwanese and Chinese manufacturers and trading companies you’ve never heard of.
It’s a lot to take in over the four days, but I managed to cover all of the halls and make it over to the Sands for a brief visit. Some colder-than-usual weather (with sleet and even hail mixed in) had people scurrying to get around, and the availability of Uber and Lyft drivers was erratic, to say the least.
Still, I came back with over 1,000 raw photos and a pile of videos that I’m still editing as this is being written. Selected highlights and trends observed at the show will follow shortly, but let me start with a few general observations. First off, this was a very laid-back CES. Ground-breaking announcements were few and far between, as were advanced technology demos.
Most of the things I saw this year had been introduced at prior shows and were simply refinements. Very little of what I saw was unexpected, and I had even predicted some of the products and trends. (It’s just a matter of connecting the dots over time.)
In the world of displays, there were ample demonstrations of quantum dot (QD) technology for backlighting televisions and computer monitors. Another major manufacturer is now on board with organic light-emitting diode (OLED) televisions, and we’re seeing the beginnings of ‘pure’ LED-based displays that use fine pitch RGB elements.
Interest in robots has spiked considerably, from table-top versions that help you wake up in the morning to models that can guide you through an airport to your flight and even check on the departure time and gate. Other robots can sweep the floor and perform mundane tasks, returning to their charging stations automatically. There was even a robot that could see and pick up objects, and some rudimentary demos of ‘learning’ robots were also on hand.
Automobiles are a BIG part of the show, particularly when it comes to all-electric models with varying degrees of autonomy. There were plenty of demos of self-driving cars and even one that can detect your emotions and physical state. Other eye-poppers included entire cars that were 3D-printed and cars with VR headsets for driving. (That last one is borderline nuts, if you ask me.)
And of course there were hundreds of examples of Internet of Things (IoT) connectivity: Smart refrigerators and washer/drier combos. Smart lighting. Smart cars. Small smart appliances. Smart scooters. For that matter, just about anything in the home or business can be connected to the Internet for monitoring and control. In some cases, all that’s needed is a plug-in USB stick. In other cases, it’s a software and hardware installation.
What follows is a somewhat random listing of show highlights. These are products or trends I felt significant enough to report on. Some were shown on the floor; others required a private visit to a meeting room or hotel suite. A few of them need to be seen in person to appreciate their significance, and if you make it to the NAB or InfoComm shows, there’s a good chance of that happening.
Light-emitting diodes (LEDs) are becoming the go-to platform for generating photons. Doesn’t matter if it’s for your TV (OLEDs, WLEDs with quantum dots), home and office lighting, dashboard indicators, or stadium signs. A new generation of so-called “micro” LEDs has come to market and is finding its way into digital signage, resulting in super-fine-pitch emissive displays with high dynamic range and very wide color gamuts.
On the television side, LG continues to make improvements to its line of OLED 4K TVs, showing models as large as 77 inches. They’ve even come up with a ‘wallpaper’ design that suspends the display on a clear glass surface, and the thickness of these displays has dropped below 5mm (that’s about ¼ of an inch). OLEDs can also flex, making them perfect for installation in cars, trucks, trains, planes – anything that moves.
In the LG Display booth, we saw prototype OLED dashboards, including a virtual instrument cluster with a transparent OLED (very cool!) overlaid on an LCD display for a 3D gauge effect. We also saw two-sided OLEDs as well as a method to use the front surface of an OLED TV as a speaker. It worked well, but by the laws of physics won’t have a wide field of dispersion.
Sony has also embraced OLED TVs with a flourish, buying panels from LG and using their own video processing in 77-inch, 65-inch, and 55-inch models. (They’re also using the front surface as a speaker.) The company is also a leader in micro LED technology; dazzling crowds with their massive 8K x 2K CLEDIS LED display made up of hundreds of seamless LED tiles. Look for more companies to embrace micro LEDs, and don’t be surprised if they start showing up in televisions by the end of the decade.
For nearly a decade, the standard illumination system for LCD TVs and monitors was clusters of white LEDs and RGB color filters; either using edge illumination and a light waveguide plate or direct illumination. A few years ago, we started to see a new way to produce more horsepower with brighter, more saturated colors and high dynamic range: Blue LEDs harnessed to quantum dots.
Now, everyone’s in the game. Samsung made the biggest splash at CES when they rolled out their “Q” line of TVs, using what they call Q-LEDs (quantum LEDs). But hold on – what Samsung calls a Q-LED isn’t really. It’s just an improved quantum dot that’s more efficient while the original Q-LED, developed by QD Vision, is a true electroluminescent device that would revolutionize displays (and probably run OLEDs out of business).
Nevertheless, Samsung dazzled with a full line of 4K quantum dot LCDs, as did Chinese manufacturers Hisense and TCL. Both companies are making a major push into the U.S. television market (Hisense sponsors a NASCAR team), and TCL is one of a handful of vertically-integrated TV manufacturers – from raw panels to finished sets. Other Chinese brands (Haier, Skyworth, Changhong, and Konka) showed 4K TVs with high dynamic range, but they don’t have the presence quite yet on this side of the Pacific.
Front projection is still very much in the game. LG, Sony, Hisense, and Changhong all showed an ultra-short-throw laser projector for home theater use that can light up a 100-inch (diagonal) screen – all with 4K image resolution. Somewhat lost in the translation was the ability to display improved dynamic range and more saturated colors (what Changhong called “flame red and pacific blue”), but there’s no question that this is a viable alternative to large screens, like the 120-inch 4K LCD TV shown by LeEco in their booth.
Unusual LCD and OLED sizes and aspect ratios continue to be popular. Samsung showed what they stated is the first quantum dot-equipped desktop monitor, a 34-inch curved model that claims 125% coverage of the sRGB color gamut and has a maximum refresh rate of 100 Hz. BenQ also showed an HDR LCD monitor using an improved panel design and coupled it with DisplayPort 1.3 (HBR3), streaming content at a maximum of 32 Gb/s from source to screen. And LG exhibited a spectacular 5K LCD monitor (5120×2880 resolution) that supports USB 3.0 Type C and Thunderbolt connections.
So how do we interface all of these displays? The big news for HDMI at the show was version 2.1, which increases the overall data rate to 48 Gb/s using speed improvements to the physical data rate per lane, plus expansion to a fourth lane and the adoption of Display Stream Compression – all the while retaining the same 19-pin connector as before (a neat trick, if you ask me). Now, will they announce a standard for native optical fiber interfacing?
Lattice Semiconductor, the parent company of HDMI, continues to dabble in 60 GHz wireless connectivity with their SNAP close-proximity wireless interconnect. As presently configured, it can support the same maximum data rates as HDMI 1.3/1.4 (10.2 Gb/s), so it can transport 4K video in the RGB (4:4:4) format at a maximum frame rate of 30 Hz, or transport 4L/60 4:2:0 video.
Over in the VESA booth, Keyssa showed their Kiss 60 GHz wireless solution, docking an Amazon Kindle tablet to stream 1080p content to a large TV. Both SNAP and Kiss utilize multiple in, multiple out (MIMO) antenna arrays and have similar data rates around 6 Gb/s upstream and downstream. What was different about Kiss is that it was making a wireless DisplayPort connection, not HDMI.
DisplayPort is also undergoing upgrades. Demos were shown of 120 Hz video output using a high bit rate 3 (HBR3) connection; maxed out at 8 Gb/s per lane. VESA also showed HDR through DP, along with a conversion to HDMI 2.0b for HDR televisions. Nearby, semiconductor designer Hardent demonstrated an improved version of Display Stream Compression, using 2:1 and 3:1 ratios. They are now venturing further by testing 4:1 DSC and its impact on latency, which with 3:1 packing amounts to just a few picture lines.
Over in the Westgate Hotel, Canadian fabless chip company Peraso unveiled the next generation of their 60 GHz wireless USB chipset, using the 802.11ad WiFi standard. In their tests, a 220 MB video file downloaded from a laptop through an 802.11ad router to another laptop in about 8 seconds (try that at home!). It’s also possible to stream wireless video in real time over USB this way.
Both Lattice and Peraso see potential for 60 GHz wireless with virtual reality (VR) and augmented reality (AR) headsets as a solution to the annoying, bulky and heavy cable bundles that go with the territory. Qualcomm, which had an enormous exhibit of 60 GHz products last year including twelve different tri-band WiFi modems and a smartphone (Letv), dialed it back this year with a modest exhibit of high-speed data and file exchange using their Snapdragon processor.
On the control side of things; you name it, it was connected to the Internet, from doorbell cameras and RFID locks to water sprinklers, shades, lights, thermostats, and major appliances. Samsung, LG, Hisense, Haier, and others exhibited interactive refrigerators with built-in LCD screens that can show video (play back recipes while you’re cooking or baking), keep track of what’s in the fridge and how old it is, prepare shopping lists and order groceries automatically (you know Amazon has a hand in that), and work as a whiteboard or virtual clipboard for leaving notes and keeping track of your schedule(s).
LG’s “knock” LCD refrigerator screen turns transparent when you tap it to see what’s hiding on the right side shelves. (Lots of potential for mischief there!) Samsung’s models will actually talk to you: You can ask the refrigerator to go out on the Internet and find a recipe and then read it back as you prepare the food. Another cool appliance, an induction oven, was shown by Panasonic. You can place everything for one meal – main course and sides – on one plate, put it in the oven, and everything is correctly heated and cooked without burning.
I’ll close out by talking about robots and autonomous cars. Machine learning is a popular topic among scientists and we’re now seeing it come to fruition. Canon showed an assembly robot that can actually see; looking for and finding parts on a table, picking them up and putting them in the correct place. Toyota’s YUI car actually senses your emotions while you drive, along with your heart rate. It can automatically suggest places to eat, a movie for a cranky child, or simply takeover driving while you catch a cat nap behind the wheel. And LG featured a guide robot that will roll up to you in an airport, scan your boarding pass, tell you the flight departure time and gate and escort you to your destination.
Granted; these are somewhat exotic examples of machine learning. But on a more mundane level, you can now design a control system that will use face recognition to unlock and enable operation of devices in your home, school, and business. Face recognition will also work in a car dashboard, as shown by Mitsubishi and others, and real-time displays will update you on weather, time, road and traffic conditions, and even suggest alternate routes.
That’s it! I’ve barely scratched the surface of what I saw at the show, and will have more posts after I have some time to gather my thoughts. (And look at that – I never once mentioned drones!)
As The World Turns: Vizio Is Acquired by LeEco

A press release crossed my desk yesterday, detailing how the TV brand Vizio had just been acquired by the Chinese firm LeEco for $2B. LeEco, while largely unknown on this side of the Pacific, is the 7th largest TV brand in China and also operates an online video content delivery business.
It’s expected that the combined operations of both companies will push them past Skyworth as the #6 worldwide TV brand, according to analysis from IHS Technology I just received this morning. (Never heard of Skyworth? Give it time.)
Vizio, which started operations over a decade ago, has become a powerhouse brand in the U.S. Although they don’t release their revenue and market share results, the company has given Samsung a run for their money over the years with a full line of televisions, most recently taking steps into HDR and UHDTV with Dolby Vision-equipped sets.
Yet, not everything the company has touched has turned to gold. There have been brief forays into smartphones (gone), tablets (gone), and computers (also gone.) In contrast, the company has done very well with sound bars, which all flat-screen TVs benefit from.
This news didn’t surprise me at all. The TV marketplace has become a very cutthroat business as prices and profits went into free fall, aided and abetted by competition from China where the nexus of LCD panel manufacturing is moving.
Numerous prominent nameplates have been victims of this downward trend, starting with Hitachi several years ago and continuing through Mitsubishi, Toshiba, and Sharp; all of whom have withdrawn from the North American TV market. (Hisense continues to sell televisions with the Sharp brand name in the U.S. and Canada.)
Panasonic, once a major player in TVs, is in the unusual position of offering an Ultra HD Blu-ray player (DMP-UBD900, $699) this fall, but no UHD televisions to bundle it with. For now, the company is not selling TVs at retail in the U.S. even though it demonstrated a 65-inch OLED UHDTV at CES that used an LG RGBW OLED panel.
Only Sony remains as a Japanese TV brand, and they’ve paid a dear price to stay in the game, losing hundreds of millions of dollars for a decade. Samsung and LG, meanwhile, have maintained their positions in the Top 5 even as worldwide TV shipments have gone into decline by an average of 3-4% per year, offset somewhat by double-digit growth in UHDTV shipments.
What’s interesting about LeEco is that, according to the HIS analysis, they’re willing to sell TVs at or below manufacturing costs – or even give them away free as a promotion – to secure paid subscriptions to their online content in China. That’s not a model that is likely to work here, but it does indicate how aggressive the new LeEco / Vizio marketing approach could be here and overseas.
Checking this weekend’s sales fliers, I spotted a Vizio 50-inch “smart” Ultra HDTV with HDR for $800 and a 70-inch model for about $2,000; both at Best Buy. Connect the dots and you can see why TV prices continue to fall, and why the bulk of TV sales are transitioning from 1080p to Ultra HD in a hurry.
Sharp (again, now made and marketed by Hisense) did Vizio one better this week, offering a 55-inch Ultra HD set for $650 (no HDR). We’re not far off from seeing $500 55-inch Ultra HDTVs, which will probably be on store shelves in time for the fall football season and certainly by Christmas.
Vizio’s conversion to a publicly-held company a year ago set the stage for this sale and is more proof of the shift in power to China for manufacturing and sales of televisions – at least worldwide. Will TCL and Hisense make further inroads to the U.S. market? What impact will they have (if any) on Vizio’s market share?
CES 2016 In The Rear View Mirror

I’m a little less than a week back from one of the world’s largest trade shows, the 2016 International CES. According to press releases from the Consumer Technology Association (CTA), the new name for the Consumer Electronics Association, upwards of 170,000 people attended the show this year, which was spread out over several venues in Las Vegas.
Based on the crowds I saw, I’d say that number wasn’t far off. Walking through booths in the Las Vegas Convention Center gave me the feeling of strolling along the beach, unaware that a tidal wave was sneaking up on you – one minute you had a particular exhibit all to yourself, and the next, you were swamped by a sea of bodies adorned with CES badges.
Trying to predict which trends in electronics will be “hot” each year is basically a fool’s errand. Going into the show, I was deluged with press releases about “Internet of Things” gadgets, and the show didn’t disappoint – I saw everything from connected thermostats and body sensors to pet food dispensers and shower heads that monitor how much water each member of your family uses – and record that data, too.
Last year, the show was all about Ultra HDTV, with some unusual video aspect ratios and pixel counts thrown in. This year, I figured high dynamic range (HDR) would be the “hot” item in every booth. Surprisingly, it wasn’t generating all that much buzz, even though it was featured in the Sony, Samsung, LG, and Chinese TV booths. Instead, there seemed to me much more interest in virtual reality (VR); examples of which were to be found everywhere in the LVCC and also over at the Sands Expo Center.
What was an eye-opener (although not entirely unexpected) was the reduction in booth space devoted to televisions in the Samsung, Panasonic, and LG booths. Sony chose to use Ultra HDTVs to illustrate HDR, wide color gamut, and local area dimming concepts, while Panasonic largely ignored TVs altogether, featuring just a 65-inch UHD OLED TV in one part of their booth and a 55-inch 8K LCD set in another; primarily to demonstrate 8K signal transport over optical fiber.
LG and Samsung devoted more real estate than ever before to connected and “smart” appliances, tablets, smartphones, and personal electronics like smart watches, subtly pushing TVs (of which there were still plenty, believe me) to a secondary role with less square footage. The fact is; appliances are more profitable than TVs these days…WAY more profitable. And Samsung and LG had plenty of refrigerators, ovens, washers, and even dryers out for inspection.
For LG, CES was a big “coming out” party for their expanding line of OLED Ultra HDTVs – they were everywhere, dazzling with their deep blacks and saturated colors. But LCD still plays a part in the LG ecosystem: The 98-inch 8K LCD panel that blew us away last year made a return appearance, as did the 105-inch 21:9 5K (5120×2160) model.
Over in the Samsung booth, they kept the “mine’s bigger than yours” contest going with a 170-inch Ultra HDTV based on a LCD panel fabbed at CSOT in China and equipped with quantum dots. (Last year, Samsung insisted their quantum dot illumination technology was to be called “nanocrystals.” This year, they did a 180-degree turn, and are now calling them quantum dots.) A curved 8K TV and some demos of live broadcast Ultra HD with HDR were also showcased alongside the company’s new Ultra HD Blu-ray player ($399 when it ships in the spring).
The “towers” and stacks of LG and Samsung televisions we used to marvel at a decade ago have now found their way into the ever-expanding booths of Chinese TV brands like Hisense, TCL, Changhong, Haier, Konka, and Skyworth. (Not familiar names? Don’t worry, you’ll get to know them soon enough.) And notable by its absence was Sharp Electronics, whose US TV business and assembly plant in Mexico were acquired by Hisense last year. That’s quite a change from ten years ago, when the company held a 21% worldwide market share in LCD TV shipments.
To be sure, there was a Sharp meeting room w-a-y in the back of the Hisense booth, which was enormous – almost as big as TCL’s behemoth in the middle of the Central Hall. And the Konka, Changhong, and Skyworth booths weren’t far behind in size. If you needed to see the writing on the wall regarding the future of television manufacturing, it couldn’t have been more clear – everything is slowly and inexorably moving to China. (It’s a good bet that the LCD panel in your current TV came out of a Chinese or Taiwanese assembly plant!)
TVs were just part of the story in Las Vegas. I had been waiting a few years to see which companies would finally pick up the baton and start manufacturing 802.11ad Wi-Fi chipsets. For those readers who haven’t heard of it before, 802.11ad – or its more common names, “Wireless Gigabit” and “Certified Wireless Gigabit” is a standard that uses the 60 GHz millimeter-wave band to transmit high-speed data over 2 GHz-wide channels.
Considering that the current channels in the 2.4 GHz and 5 GHz band are only 20 MHz wide, and that the 802.11ac channel bonding protocol can only combine enough of them to create a 160 MHz channel, that’s quite a leap in bandwidth! The catch? 60 GHz signals are reflected by just about solid object, limiting their use to inside rooms. But with high-power operation and steerable antennas, those signals can travel a pretty good distance.
In-room, high-bandwidth operation is perfect for streaming video – even at 4K resolution – from phones, tablets, set-top boxes, and even Blu-ray players to TVs, projectors, AV receivers, and switching and distribution gear. Qualcomm had demos of numerous ready-to-manufacture tri-band modems (2.4/5/60 GHz), along with LETV’s latest smart phone with a built-in 60 GHz radio chip. And SiBEAM, a part of Lattice Semiconductor, showed 4K streaming through their WiHD technology, along with close-proximity interface coupling using SNAP to download images and video from a waterproofed GoPro camera.
Lattice had some other tricks up their sleeve in their meeting room. One of those was using a Windows 10 phone with a MHL (Mobile High-definition Link) connection through USB Type-C to create a virtual desktop PC. All that needed to be added was a mouse, a keyboard, and monitor. In another area, they showed a scheme to compress Ultra HD signals before transmitting them over an HDBaseT link, with decompression at the far end. This, presumably to overcome the 18 Gb/s speed limit of HDMI 2.0.
Not far away, the “funny car” guys at the MHL Consortium showed their superMHL interface linking video to another LG 98-inch 8K LCD display. Converting what was once a tiny, 5-pin interface designed for 1080p/60 streaming off phones and tablets to a 32-pin, full-size symmetrical connector that can hit speeds of 36 Gb/s seems like putting Caterpillar truck tires and a big-block Chevy engine in a Smart Car to me…but they did it anyway, and added support for USB Type-C Alternate mode. Now, they’re ready for 8K, or so they keep telling me. (That’s fine, but the immediate need is for faster interfaces to accommodate Ultra HD with 10-bit and 12-bit RGB color at high frame rates. Let’s hear about some design wins!)
At the nearby VESA/DisplayPort booth, there were numerous demonstrations of video streaming over USB Type-C connections in Alternate mode, with one lash-up supporting two 1920x1080p monitors AND a 2550×1536 monitor, all at the same time. DP got somewhat faster with version 1.3 (32 Gb/s) and now a new version (1.4) will be announced by the end of January. The VESA guys also had a nice exhibit of Display Stream Compression (DSC), which can pack down a display signal by a 2:1 or 3:1 ratio with essentially no loss or latency (a few microseconds). If we’re going to keep pushing clock speeds higher and higher, compression is inevitable.
The world of display interfacing appears to becoming more disjointed, what with the majority of consumer devices still supporting HDMI 1.4 and 2.0, while an increasing number of computer and video card manufacturers are jumping on the DisplayPort bandwagon (Apple, HP, and Lenovo, among others). How superMHL will fit into this is anyone’s guess: The format is TMDS-based, like HDMI, but outstrips it in every way (HDMI 2.0 does not support DSC or USB Type-C operation). Do we really need two TMDS-based interfaces, going forward?
Speaking of USB Type-C, everybody and their brother/sister at CES had Type-C hubs, adapters, and even extenders out for inspection. If any connector is going to force the competing display interface standards to get in line, it will be this one. Apple, Intel, Lenovo, and several phone/tablet manufacturers are already casting their lots with Type-C, and it looks to be the next “sure thing” as we head toward a universal data/video/audio/power interface. I even came home with a credit card-sized press kit with a reversible USB 2.0 / 3.0 Type-C plug built-in!
So – how about HDR? Yes, a few companies showed it, and there were spirited discussions over dinner whether OLEDs could actually show signals with high dynamic range (they most assuredly can, as they can reproduce 15 stops of light from just above black to full white without clipping) and whether you actually need thousands of cd/m2 to qualify as an HDR display (I’m not in that camp; displays that bright can be painful to look at).
For LCDs, quantum dots (QDs) will lead the way to HDR. Both QD Vision and 3M had demos of quantum dot illuminants, with QD Vision focusing on light pipes for now and 3M partnering with Nanosys to manufacture a quantum dot enhancement film. Both work very well and provide a much larger color gamut than our current ITU Rec.709 color space, which looks positively washed-out compared to the more expansive Rec.2020 color gamut associated with UHD and HDR. QD Vision also showed the reduction in power consumption over OLEDs when using QDs. However, you won’t get the deep blacks and wide viewing angles out of an LCD in any case, so a few more watts may not matter to the videophiles.
The Ultra HD Blu-ray format had its formal debut at CES with Panasonic and Samsung both showing players. The latter can be pre-ordered for $399 and will ship in the spring. (Remember when Samsung’s first-ever Blu-ray player sold for nearly $2,000 almost a decade ago?) To support HDR – which requires 10-bit encoding – the HDMI interface must be type 2.0a to correctly read the metadata. That can be in the DolbyVision format, or the Technicolor format, but the baseline definition is HDR-10.
I saved the best for last. Every year, LG Display invites a few journalists up to what we call the “candy store” to see the latest in display technology. And this year didn’t disappoint: How about dual-side 55-inch flexible OLED TVs just millimeters thick? Or a 25-inch waterfall (curved) display that could form the entire center console in a car, with flexible OLEDs in the dashboard creating bright, colorful, and contrasty gauges?
LGD has WAY too much fun coming up with demos for this suite. I saw four 65-inch OLED panels stacked on end, edge to edge, and bent into an S-curve to create a 2.2:1 ratio widescreen UHD+ display. And it also had video playing on both sides. In another location, I saw a jaw-dropping 31.5” 8K LCD monitor with almost perfect uniformity, and an 82-inch “pillar” LCD display.
How about a 55-inch UHD OLED display rolled into a half-pipe, with you standing at the center, playing a video game? Talk about filling your field of view! Next to it was a convex 55-inch display, wrapped around a ceiling support pole. And next to that, a 55-inch transparent OLED display with graphics and text floating over real jewelry, arranged on tiers. The actual transparency index is about 40% and the concept worked great.
The icing on the cake was an 18-inch flexible OLED with 800×1200 resolution that could be rolled up into a tube or a cone-like shape while showing HD video. This was one of those “I gotta get me one of these!” moments, but significantly, it shows how OLED technology has matured to the point where it can be manufactured on flexible substrates. And what is the largest market in the world or displays? Transportation, where G-forces and vibration eventually crack rigid substrates, like LCD glass.
That’s just a snapshot of what I saw, and I haven’t even mentioned drones (buzzing all over the place), fold-up scooters and hoverboards, smart appliances, pet cams, alarms that alert you when an alarm goes off (really!), wooden smartphones (really!), talking spoons and forks (really!), toothbrushes linked to video games (would I kid you?), and 4K action cams with built-in solar cell chargers.
Gotta run now. My phone just sent me a Wi-Fi alarm that a Bluetooth-connected doorbell camera spotted the UPS guy delivering a package I was already alerted about via email to my desktop that signaled a buzzer via ZigBee in my virtual desktop PC that was connected wirelessly to my smartphone, currently streaming 4K video over a 60 GHz link to my “smart” TV that is also…also…also…
Oh, great. Now I’ve forgotten what I was talking about…Does anyone make an iRemember app? (Look for my “second thoughts” column later this month…)
The Dog Days of Summer…and UHDTV

Ahhh, summertime: When everyone’s thoughts turn to cookouts, the beach, ice cream, baseball games, driving with the top down (or moon roof open), miniature golf – I could go on, but you get the idea.
One of the things most people are NOT thinking about is buying a new TV. Sure, there’s plenty to watch, but most of us would rather be outside in the nice weather. (Kayaking is my thing this time of year).
Even so, prices continue to drop across the board on all screen sizes, even on UHDTVs. Consider HH Gregg’s flier from last Sunday, where Sharp is now advertising its new line-up of discounted Ultra HDTVs for some eye-popping prices. How about $600 for the 43-inch LC43UB30 “smart” TV? Or $800 for the 50-inch LC50UB30? Both of those prices represent $200 discounts off full retail, which was already low.
There’s even a 55-inch model, the LC50UB30, for a grand. That’s Vizio territory when it comes to pricing and shows you how determined Sharp is to get back in the TV game and recapture some of the old magic from a decade ago.
Even the newest technologies are being discounted. Samsung’s HDR-ready S-series of UHDTVs are seeing substantial price cuts, with the 55-inch UN55JS8500 trimmed by $1,000 to $1998 and the 65-inch UH65JS8500 marked down to $2998. Curved models have seen an even bigger cut of $1500 off full book (UN55JS9000 is $2498 and UN65JS9000 is $3498).
Even LG’s new OLED TVs aren’t immune. The company ran a week-long promotion earlier this month with substantial discounts. The 55EG9600 was dropped to $5,500 from $6,000, while the 65EG9600 saw its price cut by a whopping $2,000 from $9,000 to $7,000.
And back around the 4th of July, their older 55EC9300 1080p OLED TV saw a price drop to $2,300. That price has since risen back to $2,500, which is quite a discount from when it first came out two years ago and was tagged at $15,000!
Don’t need a UHD set yet? Haier would be happy if you bought one of their new 50E3500 50-inch 1080p LCD TVs, and it will only set you back $370.00 – which works out to an amazing $7.40 per diagonal inch, a new low for LCD TVs. If 50 inches isn’t big enough, Haier’s got a 55-inch model (55E3500) for $400, which is almost as good a deal.
Given the number of UHDTVs that are now priced at or below $1,000, you can expect the shift from 1080p to 4K in larger TV screen sizes to accelerate. I had figured we’d see the majority of TVs 50 inches and larger move to 2160p resolution by the end of 2017. Now, I’m beginning to think it will happen even faster – maybe by the 4th quarter of next year.
Either way, there’s no question that your next TV purchase will bring you a lot more bang for the buck. With 43 inches now the most popular screen size, you’ll be able to buy two 1080p models at a time for what one cost a year ago. And the way things are trending, you may want to consider making the move to 4K if you are upgrading over the holidays.
For now, you can just enjoy swinging in your hammock with a nice cool glass of lemonade while the birds chirp, the bees buzz, and July turns into August. There will be plenty of time to ruminate on the features sets of new TVs this fall…
LG Is “All In” With OLED TVs

Yesterday (April 8), LG formally launched its new line of OLED televisions at The Garage on Manhattan’s upper west side. In addition to showcasing the 65-inch 65EG9600 ($8,999) and 55-inch 55EG9600 ($5,499) UHDTVs, LG also held a press briefing in conjunction with Netflix’ latest streaming series, Daredevil, which is available starting Friday, April 10.
I had the opportunity to sit on this panel and answer a few technical questions about OLED picture quality. Scott Mirer, VP of device ecosystem at Netflix was also on hand to offer his observations about the new OLED TVs, as was Matt Lloyd, director of photography for Daredevil (which, coincidentally, was shot in the adjoining Hell’s Kitchen neighborhood).
During my part of the discussion, I asked for a show of hands to see how many members of the press were currently using plasma TVs, and better than 60% of the hands went up. While LCD display technology current owns about 95% of the worldwide television market, there’s just no comparison to a late-model Panasonic, LG, Pioneer, or LG plasma set when it comes to video picture quality.
Many of us shed more than a tear when it was announced that Panasonic was departing from the plasma TV business a couple of years ago. And we all figured that OLED (organic light-emitting diode) televisions would quickly step into the breach.
That didn’t quite happen like we expected. Even through large OLED TVs have been shown for well over a decade (going back to Samsung’s and Epson’s 40-inch prototypes in 2003), they just never seemed to make it to the starting line.
In the summer of 2013, LG launched a 55-inch curved 1080p OLED TV with much splash and hoopla. Later that year, Samsung followed suit with their 55-inch curved OLED TV, pricing theirs almost $6,000 less than LG. And in short order, a price war ensued – but it didn’t last very long, as Samsung pulled their product off the market for undisclosed reasons.
LG’s OLED imaging panels employ a white OLED emitter and color filters arrayed in an RGBW stripe to provide brighter images. This technology originated in none other than Rochester, NY at Eastman Kodak and was an outgrowth of research and development in the late 1970s and early 1980s.
In 2009, Kodak sold its OLED patent portfolios and business to LG Electronics outright. Ever since then, LG has been working industriously to bring OLED TVs to market. The ‘catch’ was manufacturing yields, which not all that long ago were in the low double digits.
Although subsidiary LG Display won’t disclose its current OLED yields, they are believed to be better than 50%, which is probably why we’re now seeing several models of televisions finally coming to retail. Granted; they’re not cheap – in comparison, you can by a 55-inch “smart” 1080p LCD TV for about $700 now, while a quantum dot-equipped 1080p LCD set will run about $3,000 currently.
However, the market knows what it wants to pay for a television, and you can expect those prices to come down in short order. LG’s original 55EA9800 OLED set started out at just under $15,000, but it can be yours now for just one-fifth of that original price. (For those with short memories, that’s what a quality 50-inch plasma cost about 7-8 years ago.)
While the rich blacks and saturated colors draw people like flies to OLEDs, it’s worth nothing that those same deep blacks and consistent grayscale and color reproduction at very low luminance levels allow OLED displays to show images with high dynamic range. If we go by an industry definition of HDR as 15 stops of light, OLED is definitely up to the challenge: With full white at 500 nits, for example, the step above black would measure just around .1 nits.
That’s a level of black previously attained only by plasma TVs, as well as LCD TVs with some trickery involved (black stretch, dynamic contrast, APL). But of course OLEDs can go much lower with grayscale reproduction: A more typical low gray (near black) level on an OLED display might be around .05 nits or so.
The clips of Daredevil provided by Netflix really showed off the abilities of OLEDs to handle dark scenes with point sources of high-key light, like streetlights. Another clip showed a fight scene in a dark hallway, with the only light coming from green-tinted fluorescent lamps. Yet, you could see details even in the darkest corners.
The consistent color tracking of OLEDs, their emissive structure, and their low operating voltages make them an ideal replacement – nay, step-up – from plasma display technology, which had to rely on high voltage, pulse-width modulation (PWM) technology to create images. OLEDs are also a lot thinner than any other display, and can even by printed onto flexible substrates.
But enough about technology! OLED televisions are finally coming to market, and that’s something to celebrate. As a bonus, both of LG’s newest OLED models are UHDTV-resolution (3840×2160 pixels) and have excellent 1080p upscaling, based on the Blu-ray clips of Skyfall that I saw at the event. Can’t wait for the rest of the lineup!
