Clive Couldwell talks about the early industry history with staunch supporters of stage and screen. Rank 45 and Hi Beam, Sony JumboTron, the emergence of LEDs and the explanation of the new technology being developed. Are all there.
You can say that Graham Burgess of digiLED is what we call AV scene from the beginning. In the 1980s, he worked at Cameron Communications for three and a half years, when Cameron Communications was a distributor of Barco and Rank Video Systems (marketing Rank 45 and Rank Hi Beam).
He recalled: "I was a big screen guy." "Of course-then-the huge screen is much more complicated than today. The demonstration will take at least half a day-if you try to connect to an IBM mainframe, Apple II (8-bit Computer) or Apple Lisa (one of the earliest personal computers that used GUI for business users), the demonstration will take longer.), and then half a day to demonstrate for customers."
Burgess moved to Sony in 1985-initially working for Sony Broadcasting and Professionals in northern England, and eventually moved south to London, where he became the company's national sales manager and then general manager of the so-called Specialist Business Group. "I have been in charge of multiple areas, but what really excites me is the ultimate giant video screen JumboTron."
(JumboTron is a large video board that is considered one of the largest non-projection video displays ever produced. Sony’s creative director Yasuo Kuroki also helped create the Walkman, thanks to its development. )
"At the time, JumboTron achieved incredible success in Japan and North America, but almost no success in Europe. My task is to change this situation. I was lucky to have the opportunity to sell two JumboTrons early It was given to Michael Jackson for a "dangerous" trip in 1992. Around the same time, Chris Sullivan, one of my JumboTron colleagues in North America, made a deal with Genesis "We can’t dance" tour. "So that year, JumboTron probably participated in two of the most high-profile tours-one in the United States with a British artist, and another in Europe (Munich Olympic Stadium) on a trip with an American artist, both of which used a very early version, "modular screen,"" Burgess said.
Over time, JumboTron’s tour form used what was called “module” at the time, which gave birth to an event that became an industry in itself-event companies used huge video in the field of AV rental and stage performances (eventually LED )screen.
"The following year, when Arsenal decided to install a giant video screen at Highbury Stadium in the UK, we felt lucky again in the UK," Burgess recalled. "At the time, the cost of outdoor giant video screens was coveted, so we made a proposal for Arsenal based on the use of the'modular' technology developed last year, but the purchase cost was offset. When they did not use the screen for rental Used for football matches."
The idea is excellent. Arsenal use the screen approximately 25 times a year for all home games, and Screenco (now part of Creative Technology, then part of Avesco, but now part of the huge NEP TV empire) gets it in another 340 days The right to use the latest technology. A commercial rental fleet for its activities for one year. He said: "Within a few years, we made similar deals with the Glasgow Rangers, Blackburn and Spurs, installing modular and permanent giant Trons."
It may be worth mentioning that the area of a module was about 2 square meters and the weight was close to 200 kg (100 kg per square meter). "Today, a typical rental module is about 30 kg per square meter, and if you pay a premium, it may be even less," Burgess said.
Screenco and its US partner BCC/Screenworks and Australian joint venture Screenco Pty purchased more JumboTrons so they can handle their round-the-world travel. "Since then, JumboTron has become a universal product for giant video screens in the rental industry, achieving similar successes that have been achieved in North America and Japan," Burgess added.
By 1998, LED technology began to appear all over the world. Although it was not as good as the CRT, it was quickly shut down, and it was clear that Sony’s life in the giant video screen business was limited. Therefore, in 1998, Burgess joined the Avesco Group (then the parent company of CT and Screenco) and established a new company, Pixel Displays (PIXELITE), which had merged into Lighthouse Technologies in 1999, where Burgess He assumed the responsibilities of Group Sales and Marketing International Director, Managing Director of Europe, Middle East and Africa.
In the next five years, Lighthouse quickly grew into one of the major players in the LED screen business, even if it was not a major player, it was acquired by the Hong Kong-based Gold Peak Group.
Burgess said: "This has brought me great changes. It's time to move on." "With my background in the big screen field, trying to enter a new industry will be very difficult, and I spent some time thinking about how Stay in the industry while not suitable for being a manufacturer, leasing company or integrator."
Therefore, Burgess came up with the idea of becoming a broker mainly for second-hand screens, and also becoming a broker who needs new screens, thus forming digitalization (displayLED at the time).
Then came the early projects of Coca-Cola (Piccadilly Circus), RFU Twickenham (TFU), Arsenal Emirates Stadium, Thomson Reuters and Westfield White City, all using Equipment from various manufacturers (Daktronics, Mitsubishi, Barco, Beacon). Burgess recalled: "By 2007, we were ready to introduce a series of low-cost digiLED devices originally designed in Europe but manufactured in China and South Korea."
Seventeen years later, digiLED is headquartered in London, with offices in Las Vegas, Shenzhen, Hong Kong, Tokyo and Milan, and a technical development team in China, responsible for outsourcing the manufacturing of digiLED series products for global customers.
In short, we have entered the field of managing the supply chain for our customers. This is partly attributed to our understanding of LEDs, but more and more of our understanding of LEDs, especially in China and even the entire Asia, is gradually becoming the main difference between us and our competitors. "
"As we move to higher resolution LEDs, the biggest challenge is the flexibility of current SMD displays. We are beginning to see some new technologies designed to solve this problem." Burgess believes that LED screens have many potential technologies under development:
GOB (Glue on Board)-Simply paint on the surface of SMD tiles to enhance contrast and resist damage during installation. Burgess said: "Consistency in maintenance and consistency is the main obstacle to the wide acceptance of this technology."
Mini LED-By producing pixel clusters (Nationstar's 4-in-1 device is probably the most famous of them), manufacturers can achieve simpler soldering and maintenance, and increase the robustness of the display. He said: "So far, micro LEDs have achieved mixed results. Although they have been widely used for a year or more, they have not yet been widely adopted."
COB (Chip On Board)-LED can be fixed to PCB and directly bond LED chip without wave soldering process. "Like GOB, it is stronger and more resistant to damage, but the process is affected by the consistency of yield, color and contrast."
Micro LED-GOB, Mini LED and COB can all be considered as temporary technologies because technology companies focus their energy on Micro LED-taking into account the development of The Wall based on Sony CLED and Samsung.
"In many development laboratories, we are achieving successful yields and increasing the speed of mass transfer of wafers to PCBs. We may not see commercial micro LEDs for some time.
Of course, Covid-19 may become a factor in the speed of development work.
"Four months ago, we could have looked forward to the future and waited for the arrival of these new technologies. However, the main question now is whether screen manufacturers can continue to develop new technologies and bear all the costs. The industry provides existing technology without having to spend scarce cash resources on development costs." Burgess said.
"My money may be spent on the latter, at least in the short to medium term, although any manufacturer that has the courage to continue to develop may gain a clear advantage in the competition."

Update: Apple leakers (0-0-0) and Ross Young of DSC say that OLED for iPad Pro will not happen in 2021. It may happen in 2022.
It looks like i'm always right
Well, Rose agrees with me! perfect!
Samsung and LG Display each refute the story of producing OLED for the iPad Pro in 2021, although 2022 may...
-Ross Young (@DSCCRoss)
It has been making major changes to its equipment, and after the Mac lineup, the iPad Pro series is next. Although the proposed changes for the upcoming iPad Pro are not as drastic as we see on Mac devices, they are interesting.
The giant in Cupertino is rumored to be developing
Display companies expect the displays used in most of their devices. Now, it is said that the first device with a Mini LED display panel is the iPad Pro.
, IPad Pro equipped with Mini LED display panel will be released in the first half of 2021. Not only that, it is said that the company is also developing an OLED panel for the iPad Pro, which will be released in the second half of the year. next year
It is also reported that Apple will
And LG Display. The two companies also provided Apple with OLED panels for the iPhone 12 launched last month.
The report also added that Apple will actively start using Mini LED panels in the iPad series next year, and then gradually start using the same screen types
And the iMac series. But there is no specific timetable for development.
Previous reports indicate that the technology giant may purchase Mini LED panels from Epistar. There are also reports that the company
San'an Optoelectronics, headquartered in China, will start production from Apple, and after obtaining certification in mid-2021, enter Apple's supply chain by 2022.
Mini-LED seems to be the upcoming transition technology
The giant based in Cupertino has been working here for several years. According to reports, Apple began research and development at a manufacturing plant in California as early as 2018. However, it is said that we will not be able to see micro-LED displays on smartphones until 2023 at the earliest.
