The Times They Are A-Changing: Hisense Buys Toshiba’s TV Business

This press release crossed my desk this afternoon. There’s not much to add to it. Hisense already owns the right to manufacture and sells televisions with the Sharp brand. Now, they’ve acquired Toshiba’s television business unit.

Toshiba, which had been rocked by an accounting scandal and red ink, and which is reeling under the costs of the Fukushima nuclear plant meltdown, had basically given up on the TV marketplace a couple of years back.

Now, they’re out for good, and some analysts are wondering what future if any the company has “as a going concern.”



Hisense Purchases Toshiba Television Business

Hisense Electric Co., Ltd, a publicly listed subsidiary of Hisense Group announced the purchase of Toshiba TV production, brand, R&D & operation service 14th November, 2017.

With its 142-year rich history, Toshiba has a leading display technology in Japan with the brand ranked highly international global technology brand list’s.

Hisense will purchase 95% stock shares of Toshiba Visual Solutions Corporation (“TVS”), a wholly owned subsidiary of Toshiba Corporation for 12.9 billion Japanese Yen with Toshiba retaining 5% stock holding. Hisense will obtain the TVS businesses including production, research and development, and sales functions as well as license to use the Toshiba brand for a period of 40 years for visual solution partners operating in Europe, South East Asia and other markets.

TVS primarily operate in TV and variety of ancillary products, including commercial and advertisement display products. The TVS purchase also secures two factories in Japan and hundreds of talented Toshiba R&D employees as well as a significant IP portfolio relating to TV technology business patents for image quality and acoustics.

Mr. Liu Hongxin, the CEO of Hisense Group, said that Hisense would optimize TVS’s resources on R&D, supply chain or global sales channels, cooperate with and support each other in display technology, provide competitive content operation services for smart TVs for the global market and accomplish fast growth in Japanese market.

According to the IHS, sales of Toshiba TV ranked No.3 in Japanese market in 2016 with the Hisense TV market share in Japan the highest among all non-Japanese brands. Collectively both brands cumulative market share reaches over 20% after the transaction. Hisense’s TV business in 2016 ranked third in the world (IHS) and has held NO.1 market share in China for 13 consecutive years.

As Official Television Sponsor of the FIFA World Cup Russia 2018, Hisense is poised to continue to expand and implement its global brand vision and strategy. With the benefit of this acquisition, Hisense will develop and enlarge its international strategy of TV business in R&D, branding and marketing by operating under multiple brands. The cooperation between Hisense and Toshiba will drive changes to the new picture of TV business.

On LED Walls Versus Projectors and Who Ultimately Wins This Battle

It’s been a busy summer for me, travel-wise. In addition to jaunts through Quebec and Korea, I’ve been in Chicago and New York, meeting with manufacturers and checking out the latest in television, projection, and large screen display technology.

I wrote about my visit to LG Electronics last month and their deep dive into organic light-emitting diode (OLED) technology. As part of my visit, I saw some clever uses of OLED panels in super-large videowalls mounted conventionally, mounted overhead, and even warped around different surfaces.

My trips to Montreal and Chicago also led me to inspect numerous and more mainstream inorganic LED wall installations, ranging from the Montreal Jazz Festival to the new block of shops and entertainment venues in and around Rosemont, just east of O’Hare Airport.

What’s mind-boggling is how quickly LED signs have become the dominant display medium and how they’ve essentially booted high-brightness projectors to the sidelines. I can’t remember a concert I’ve seen this year that used video projection – either the area behind the stage was filled with an LED wall, or towers of LEDs were arrayed to either side of the stage.

It’s been like that for concerts I’ve attended in recent years by Paul McCartney (twice), The Moody Blues, Steely Dan, and Sting. The move to LEDs for image magnification has put a noticeable dent in the sales and rentals of projectors, as many of my colleagues in the industry have mentioned. While there are still tours that use some complex projection effects (Roger Water’s various “Wall” tours come to mind), it’s clear that LEDs are the new 800-pound gorillas.

For a festival like Montreal, LEDs make perfect sense. Multiple temporary stages are set up outdoors near the downtown area and performances run continuously from noon until late in the evening. Ambient light levels are all over the place and large crowds form around each stage, constraining the available footprint for AV support. Aside from rear projection, direct-view displays make the most sense.

In Rosemont, an area that was supposed to be a casino, nestled between I-294 and the hotels and convention center on River Road, has instead become a vibrant outdoor mall and concert space, surrounded by restaurants, a bowling alley, an indoor sky-diving attraction, a high-end AMC Muvico theater, and the headquarters of the Big Ten television network. Across nearby Balmoral Avenue lies the Fashion Outlets of Chicago Mall and Rosemont Theater – all replete with big LED signage.

Think about it. If you can stuff 4k worth of pixels into a screen this size AND support HDR and WCG, why would you use a projector?

This fascination with LEDs hasn’t gone unnoticed by the leading manufacturers of LED tiles, most of whom are based in China. I noticed at least a dozen LED tile/wall manufacturers at NAB in April and too many to count at InfoComm in June. The problem is that most of these companies are unknowns to folks in the rental and staging business, so the sharper minds are hiring American industry veterans to handle sales and marketing of their products, hoping to get a foot in the door.

I’m also hearing concerns about product reliability, which generally scares away R&S folks. The gear absolutely must work Monday morning at 8:00 AM as the meeting kicks off or 8:00 PM as the house lights go down– no excuses. With projection, stacking redundant projectors might be an expensive fail-safe, but it works. So does having extra lamps in the optical chain – if one fails, the projected images might be slightly dimmer, but the show goes on.

But how do you provide redundancy for LED displays? Granted, the manufacturer can include extra power supplies in case of a major failure. But what if a column or row driver goes out? Driving home last night along a major interstate, I noticed a prominent LED outdoor sign along the road that had a large, L-shaped black area on it – those tiles had failed completely. Whoops!

It’s rare that imagers fail in high brightness projectors – usually the lamp goes, or there’s an issue with the power supply. But projection technology is mature, compared to LEDs: The first solid-state high-brightness projectors made their appearance in the mid-1990s, over two decades ago, and there’s been ample time to work the bugs out. LED displays were around back then, but they had very coarse dot pitches, were extremely costly to install, and were limited to venues like stadiums and arenas.

Now, we can achieve 4K+ resolution with fine-pitch LED tiles that range from 1.8m down to .9mm. This, of course, increases pixel density, wiring complexity, and power requirements. The upside is a level of brightness on huge screens you’d be hard-pressed to match even with stacks of projectors. To equal a 2,000 cd/m2 16×9 LED wall measuring 24 feet x 13.5 feet (324 ft2), we would need a projector stack that could pour out 190,000 lumens. (And likely a separate power plant to operate it, too.)

If the history of the AV community has taught us anything, any new technology that represents a real breakthrough will win out in the end, failures or not. And that describes LED walls to a “T”. Industry veterans will recall continual headaches with the first high-brightness LCD and light-valve projectors (remember the temperamental image light amplifiers from the late 1990s?) that are now just distant memories. High-brightness projectors are very reliable nowadays, which is a great thing.

LED walls are becoming popular for set backdrops, especially for news broadcasts.

What’s not so great is that they’re falling out of favor for larger-than-life displays, and LED walls are rushing in to fill the void. High brightness, excellent contrast and color saturation, fine pixel pitches, small footprints, modular design and assembly, one-piece solutions – these are all substantial advantages over projection.

The sticking point remains product reliability, 24/7 manufacturer support (essential for staging), and customer service in general. And the Chinese LED wall manufacturers appear to be taking these challenges seriously, based on the flurry of press releases I’ve gotten this year that have announced key hires for their American offices.

If these three challenges can be overcome, I think we all know how this story will end. Projector manufacturers will have to be satisfied with a smaller slice of the pie, going forward. And it might even get smaller: Samsung has announced an initiative to place large, fine-pitch LED screens in movie theaters, promising a high dynamic range (HDR) viewing experience that they claim can’t be equaled with projection technology – even those equipped with lasers.

I’ve been in this industry long enough to remember when “state of the art” in staging meant 35mm slide projection, CRT video projection (with standard-definition video), and 16mm film here and there…and that was just three decades ago. Here we go again…

LG Is “All In” With OLEDs (Updated)

Last month, I was invited to visit LG Display’s manufacturing and R&D facilities in Paju, Korea; something I had been hoping to do for several years. The trip was motivated by the many display exhibits I’ve seen at LGD’s CES suite every year – a suite we often refer to as “the candy store” because so many cool display concepts are in the spotlight.

At Paju, our small group was able to take a quick look at the mostly-automated LCD assembly process in one of the large fabs (P7) and tour an extensive Innovation exhibit, showing off the company’s latest developments in both LCD and OLED tech. Nearby, an enormous P10 fab was under construction; one which will be used to manufacture hundreds of thousands of OLED display panels each month.

While there are several different companies engaged in OLED research and development and others that manufacture smaller quantities of smaller OLED screen sizes, LG Display has decided to put all of its chips on this technology for televisions. The underlying science originally came from Eastman Kodak’s work on white OLED emitters in the 1970s and 1980s, and LG Display acquired the rights to that intellectual property several years ago.

Given the plethora of LCD manufacturing fabs in Asia and the plummeting costs of LCD TVs (largely due to China’s increasing dominance in the market), the LCD manufacturing and TV business is fast becoming a zero-sum game. It’s why legacy brands including Toshiba, Hitachi, Mitsubishi, and Panasonic have exited the consumer television market – the profit just isn’t there.

So a big investment in OLEDs is quite a gamble, especially since televisions using this technology sell for higher prices than comparably-sized LCD sets. Right now, a 55-inch Ultra HDTV using OLED technology retails between $2,000 and $3,000, depending on whether there is a sale or special promotion.

LG’s massive P10 OLED fab, under construction in Paju and seen from the conference suite atop the P7 LCD fab.

65-inch sets are even more expensive: A quick check on the Best Buy / Magnolia Web site shows a variety of OLED TV models (including one from Sony that uses LG Display panels) ranging in price from $3,000 to $5,500. There’s also an LG 77-inch model for $15,000, if you want to go that big.

Some perspective is useful here. Way, WAY back in the mid-1990s, a 50-inch 720p/768p plasma TV would set you back between $25,000 and $30,000. Before plasma manufacturing stopped just 15 years later, you could pick up a 50-inch 1080p model with “smart” functions for as little as $500. So it’s reasonable to assume the downward price curve will come into play once again as demand ramps up.

OLED display technology is a very different beast than LCD and has more in common with CRTs and plasma, since it uses an array of emissive color pixels (plus white pixels for higher brightness). Emissive architectures don’t have the issues that hamstring LCDs, such as contrast flattening and color de-saturation when images are viewed off-axis. As we saw in an eye-opening demo using a star field on a deep black background, edge-illuminated HDR LCD TVs can create an unwanted “shaft of light” artifact while trying to modulate black levels across a small a local area and still maintain high brightness and contrast. OLEDs have no such difficulty with this type of content – the high-contrast star field images reproduced as you’d see them in real life, displayed as intense point sources of light on a near-black field.

This massive curved, tiled OLED videowall greets visitors to the Seoul Tower lobby.


Here is a “cylinder” display, made up from large UHD OLEDs.

The OLED “stack” is also much thinner than an LCD – in the case of the new LG “wallpaper” OLED displays, it’s just 4 mm. Since it’s also possible to form OLED pixels on plastic surfaces, we can create a different class of flexible displays. I’ve mentioned this more than once on previous occasions: The largest market in the world for displays is transportation. Think of anything that moves and transports people and goods – ships, trains, planes, cars, trucks, subways. G-forces and sustained vibrations are the two biggest threats to displays in these applications. By making the substrates thin and flexible, we can minimize the long-term effects of both threats.

The behavior of OLEDs as they slowly come out of black (quiescent state) to full white is very predictable – these are low-voltage devices, after all – and it’s possible to show images with very low luminance values that are not limited by the inherent characteristics of LCDs. Even the best plasma displays that used fractional, low-luminance pulse-width modulation techniques can’t equal the performance of an OLED.

There’s always a ‘catch,’ though. OLEDs (like any other emissive display) have a practical brightness limit. For a full white screen, that’s in the range of 100 to 200 cd/m2, while a 10% window can hit about 600 cd/m2. Contrast that with an LCD TV equipped with quantum dots, which can achieve a peak small-area brightness measurement in excess of 1000 cd/m2.

But everything is relative. While you may need more horsepower if you are viewing images in a brightly-lit room; in a darkened room or in the evening, 500 cd/m2 peak brightness is more than adequate. And the ability of OLED displays to render shadow detail down to near-black (close to .0005 cd/m2) means they can show images with high-dynamic range – over 20 stops of light can be displayed from just above black to 100% white.

This OLED tunnel is similar to the one shown at CES 2017. It’s also located in the Seoul Tower.


This 6×6 OLED wall uses older 55-inch 1080p panels and is positioned in the entrance lobby to the Paradise Casino near Incheon Airport.

The other ‘catch’ has intrigued us display analysts for years, and that is differential aging of different OLED colors. While green and red appear to have acceptable half-life spans, dark blue has always been a challenge. Sony’s original 25-inch and 17-inch TriMaster RGB OLED monitors acknowledged as much by raising the power consumption over time to maintain a 100 cd/m2 brightness target as the blue emitters decayed. Samsung’s first 55-inch curved OLED TV – shown about 4 years ago – used dual blue emitters that were twice the size of the red and green emitters, another way to tackle differential aging.

LG Display’s technology uses a white OLED emitter that combines two doped compounds. One by itself emits blue light, while the other emits yellow light. Together, they create white light, and RGB color filters round out the package. The combination works very well, although LG Display adds a white pixel for every red, green, and blue combination to boost brightness. (Presumably this trick sacrifices a bit of color saturation and certainly makes for plenty of animated discussions among home theater enthusiasts!)

While speaking with Dr. Jang Jin Yoo, who heads up LG Display’s Image Quality Development Department, I asked if there was any measureable decay in the blue doped compound over time. If so, this would result in images with a yellowish tint. His reply was that the white OLED emitters should last 20,000 hours before any such decay might be observed, at which point the entire OLED array might have reached 50% of initial brightness. (And it’s likely that you would have replaced the TV long before then anyway.)

Here is a flexible plastic OLED dashboard for cars and trucks. It has excellent brightness, contrast, and color saturation and will simply flex with bumps and vibration.

My other question had to do with something I observed at the 2016 CE Week TV Shoot-Out conducted by Bob Zohn of Value Electronics. I didn’t make this year’s event as I was in Korea, but at last year’s running I had observed a greenish tint on a 55-inch LG OLED TV when viewed off-axis at just 30 degrees. The folks at LG Display in Paju had not heard of this previously, so I loaded up a few photos on my phone to show them what I saw. (This phenomenon was confirmed by Joe Kane and a few other golden eyes.)

The answer? There wasn’t any forthcoming during our visit, but I’m hopeful I may get one eventually. It may have been a production issue with 2016 models, and I don’t know if the same thing was seen this year at the Shoot-Out. My theory was that something in the TV’s optical path was acting like a bandpass filter, attenuating red and blue light output off-axis while boosting green response.

The green color cast I observed on an LG 2016 55-inch Ultra HDTV last year. My viewing angle is about 30 degrees off the centerline.


Here’s another view of the green shift. To date, I still haven’t gotten an explanation from anyone at LG as to what might have caused this and if it’s been addressed.

If you are a display aficionado, you know that the best images consistently come from emissive displays – bright, saturated colors, wide viewing angles in both axes, low black levels, and excellent contrast. Over time, we’ve weaved back and forth from motion picture film (transmissive) to CRT televisions (emissive) to rear-projection television (transmissive) to plasma TVs (emissive) to LCD TVs (transmissive).

With wider adoption of OLED technology, we are swerving back into the emissive lane again. And if you need any convincing that emissive is here to stay, look at the wave of fine-pitch, super-bright inorganic LED displays now available for commercial displays: They’ve already put a dent in sales and rentals of high-brightness front projectors and are becoming the preferred backdrop display for TV news broadcasts.

We’re a long ways off from micro LED TVs in our living rooms. For now, the next best thing is OLED technology. In addition to LG’s lineup, Sony is now selling two models with LGD panels – will others jump on board? Panasonic had a nice 65-inch offering using the LGD panels, but took it off the market. Will it come back as a companion to Panasonic’s UHD Blu-ray players?

From what I could tell, LG Display believes the future of displays is OLED technology – that’s where the bulk of their capital investments are going. They expect to finish their massive P10 OLED fab line sometime late this year or early next year, at which point they will be able to roll larger sheets of motherglass and yield more cuts. That should bring 55-inch and 65-inch UHDTV set prices down to a level that consumers expect.

Those are my observations from Korea for now. Look for more thoughts on OLEDs in future columns…

My two able guides, Sue Kim of Insight Communications and Jean Lee from LG Display PR. We’re posing at 486 meters above the ground in the Lotte World Tower – the 5th-tallest building in the world. (It has a few LG OLED displays in its lobby!)


How tall is 486 meters? THIS tall…

EDITOR’S NOTE: This article has been updated to correct the thickness of a 65-inch OLED panel (4mm, not 2.5mm) and peak brightness in a 10% window (600 nits, not 500 nits).

*LG Display also contacted me after publication to state that the expected time to half-brightness for white OLEDs is officially 50,000 hours, not the 20,000 hours quoted in this article. As a veteran of many years in the display industry, I have seen half-brightness specifications like 10,000, 20,000, and 50,000 hours used far too liberally in the past to believe most of them. I would have to see more specific aging studies that could substantiate a half-brightness claim of 50,000 hours, and as I wrote in my article, it’s unlikely anyone would keep a television long enough to rack up even 20,000 hours on it in any case.

If you watched television for 6 hours a day, 365 days a year, that would amount to 2,190 hours, and at that rate, you’d hit the 20,000-hour mark in just over 9 years. It’s highly likely you would have replaced your television by then.

A New QLED Artifact

During the week of July 9 I, along with three other media/analyst types, was LG Display’s guest in Seoul and Paju for a tour of facilities and interviews with executives. During that trip, LGD engineers showed me a display artifact in Samsung’s Q Series of quantum-dot LCD-TVs previously unknown to me and my colleague Pete Putman, who was also on the tour.

LGD and Samsung are in a pitched battle to convince consumers (and the media) as to whether the Q Series or LGD’s OLED-TV offer the superior image, so the Q Series is what LGD focused on in the darkened lab in LGD’s huge Paju panel manufacturing complex. But, as you will see, it is likely that the artifact would be seen on any LCD-TV that uses edge-lighting and one-dimensional (1D) local area dimming. The Q Series uses such a system, with the LEDs distributed along the bottom edge.  (Although the artifact was new to Pete and me, I have since learned that Ray Soneira of DisplayMate described a related artifact discovered in tests and analysis he performed in 2015 and 2016.  Since he used a different test pattern the details of the artifact were not the same as what I observed, but both artifacts have the same origin.)

Photos were not permitted in the lab, but the concept of 1D dimming is shown in this photograph taken in the Corning booth at the most recent SID Display Week. Each local dimming zone is the vertical beam of light emanating from the LED on the bottom. The artifact was demonstrated by an image of a bright moon in a star-filled black sky. The LED for the zone containing the moon brightened in order to produce the desired high luminance for the moon, but in doing so it made all of the stars within the beam brighter, and created the appearance of the sky within this zone being less black. If the moon moves across the screen, so does this “searchlight beam,” which all of us were soon calling a “halo” or “halation.” The effect was obvious and not-at-all subtle. The effect can arise whenever there is an array of bright points on the screen combined with a larger or brighter object, or even if the distribution of points is significantly uneven.

These images were shown by Corning at Display Week to demonstrate how the better local dimming index of Iris glass produces a better defined LED beam (right) for more effective 1D local area dimming. The contours of such beams should not be visible in the TV image seen by the viewer, but they were strongly suggested by the “halation pattern” described in the article. (Photo: Ken Werner)

Although this effect is likely to be most disturbing to buyers of expensive premium LCD-TVs, there is no reason to think that the artifact is caused by quantum dots. It should be visible on any edge-lit LCD-TV. But, ironically, because less expensive sets are likely to have a lower “local area index” — see the left side of the photo — the local-area dimming will less effective and the artifact should be less obvious.

The artifact could be removed by using two-dimensional (2D) dimming implemented with a full-array backlight. With this type of backlight, the LEDs are arrayed evenly behind the LCD in a backlighting rather than edge-lighting configuration. Less expensive sets use a relatively small number of LEDs, resulting in low cost and less effective local dimming. Expensive sets use a large number of LEDs for excellent results at a higher cost. (Reasonably well-populated full-array backlights can have their own artifacts, but the ones I’ve seen are more subtle than the halation I saw at Paju.)

So why not used the full array? I have not discussed this with Samsung specifically but full-array backlights, although thinner than they used to be, are considerable thicker than edge-lights, particular those implemented with Corning’s Iris glass instead of acrylic. And, if you go for quality rather than economy, they require more LEDs and therefore cost more.

Isn’t a full-array backlight’s modest increase in thickness worth while if it permits images with fewer artifacts? For many readers of the answer is probably yes. But to the marketing imagination “thin” equals “quality,” and when your competition includes an OLED-TV so thin and light in weight it can be mounted directly on a wall, deciding to go thicker is likely not an easy call.

InfoComm 2017 In The Rear View Mirror

InfoComm 2017 has come and gone, and left us with lots to think about.

For me, this year’s show was hectic, to say the least. I presented my annual Future Trends talk on Tuesday to kick off the Emerging Trends session, then conducted a 3-hour workshop on RF and wireless that afternoon to the largest crowd I’ve ever had for the class. (It may be the largest crowd I ever get as I’m thinking of shelving this class.)

Bright and early on Wednesday morning, I taught a 2-hour class  on AV-over-IT (the correct term; you could also use “AV-with-IP”) to a full house. There were even some folks standing in the back of the room. I guessed at least 200 were in attendance.

Thursday morning found me back in the same space, talking about 4K and Ultra HDTV to a smaller crowd (maybe not as “hot” a topic?) and urging them to set their BS meters to “high” when they headed to the show floor to talk to manufacturers about 4K-compatible/ready/friendly products.

With other presentation commitments, it worked out to nearly 15 hours standing in front of crowds and talking. Tiring to say the least, but I did get a ton of great follow-up questions after each session. People were paying attention!

AV-over-IT was a BIG theme at InfoComm, and it was hard to miss.

Mitsubishi had a very nice fine-pitch LED display at the show – one of the few that are not built in China.

The migration to using TCP/IP networks to transport video and audio instead of buying and installing ever-larger and more complex HDMI switchers and DAs is definitely catching steam. My colleagues and I have only been talking about this for over a decade and it’s rewarding to see that both manufacturers and end-users are buying in.

And why not? Computer hardware couldn’t get much cheaper. For my AV/IT demo, I was streaming a local TV station, broadcasting in the 720p HD format, using an H.264 AVC encoder/decoder pair running through a 1GigE NetGear managed switch. The streaming rates were in the range of 15 – 18 Mb/s, so I had plenty of headroom.

It worked like a champ. I was able to show how adjusting the group of pictures (GOP) length affected latency, along with the effects of constant bitrate (CBR) vs. variable bitrate (VBR) encoding. If I could have dug the gear up in time, I would have demonstrated UHD content through a 10 Gb/s switch – same principles, just a faster network.

I saw more companies than ever this year showing some sort of AV-over-IT solution. (Almost as many as those showing LED walls!) Lots of encoders and decoders, using H.264, Motion JPEG, and JPEG2000 formats; connected through fast switches and driving everything from televisions to projectors.

If it’s REALLY happening this time, then this is BIG. Migration to AV-over-IT is a big shot across the bow of companies that sell large HDMI-based matrix switches, not to mention distribution amplifiers and signal extenders – both made obsolete by this new technology. With AV on a network, all you need is a fast switch and a bunch of category cable. For longer runs, just run optical fiber connections to SPF fiber connections on the switch.

LG showed off its unique curved OLED displays – and they’re dual-sided.

Meanwhile, Samsung unveiled the first digital signage monitors to use quantum dot backlight technology for high dynamic range and wide color gamuts.

Hand-in-hand with this migration to an IT-based delivery system is a steady decline in the price of hardware, which has impacted the consumer electronics industry even harder. Consider that you can now buy a 65-inch Ultra HDTV (4K) with “smart” capabilities and support for basic high dynamic range video for about $800.

That’s even more amazing when you consider that the first Ultra HD displays arrived on our shores in 2012 with steep price tags around $20,000. But the nexus of the display industry has moved to mainland China, creating an excess of manufacturing capacity and causing wholesale and retail prices to plummet.

There is no better example of China’s impact on the display market than LED display tiles and walls. These products have migrated from expensive, coarse-resolution models to super-bright thin tiles with dot pitches below 1 millimeter – about the same pitch as a 50-inch plasma monitor two decades ago.

Talk to projector manufacturers and they’ll tell you that LED displays have cut heavily into their business, especially high-brightness projectors for large venues. LED wall manufacturers were prominent at the show, and some are hiring industry veterans to run their sales and marketing operations; removing a potential barrier to sales in this country by presenting potential customers with familiar faces.

Panasonic showed there are still plenty of applications for projection, especially on curved surfaces.

Absen is an up-and-coming LED brand, and they’re hiring veterans of the U.S. AV market to push sales along.

At the other end, large and inexpensive LCD displays with Full HD resolution have killed off much of the “hang and bang” projector business, and large panels with Ultra HD resolution are now popping up in sizes as large as 98 inches. The way things are going in Asia, Full HD panel production may disappear completely by the end of the decade as everyone shifts to Ultra HD panel production.

Even the newest HDR imaging technology – quantum dots – made an appearance in Orlando in a line of commercial monitors with UHD resolution. Considering that QD-equipped televisions have only been around for a couple of years, that’s an amazingly accelerated timeline. But compressed timelines between introduction and implementation are the norm nowadays.

This was my 24th consecutive InfoComm and the 21st show (so far as I can remember) where I taught at least one class. When I went to my first show in Anaheim, CRT projectors were still in use, a ‘bright’ light valve projector could generate maybe 2000 lumens, LCD projectors cost ten grand and weighed 30 pounds, and composite video and VGA resolution ruled the day. RS232 was used to control everything and stereo was about as ‘multichannel’ as audio got.

All of that has passed into oblivion (except for RS232 and VGA connectors) as we continue to blow by resolution, size, speed, and storage benchmarks. The transition to networked AV will result in even more gear being hauled off to recycling yards, as will advances in wireless high-bandwidth technology, flexible displays, cloud media storage and delivery, and object-based control systems.

Can’t wait for #25…
