In something of a rematch of the groundbreaking session at the NAB Cinema Summit in April, “Laser Illuminated Projectors: What’s New and When Will They Arrive?” Monday’s Display Summit at InfoComm saw a special High-lumen Laser projection session, the “Digital Cinema Laser Battle” with the same companies squaring off—and with the same implications for all large venue projection, not just cinema. But in slight shifting of chairs this time, the moderator was none other than digital cinema guru Michael Kargosian (perennially one of the key architects of the NAB Cinema Summit), with the NAB session’s moderator Bill Beck now wearing the Barco hat, while Christie’s Don Shaw and NEC’s Richard McPherson reprised their NAB shoot-out roles. But despite the slightly musical chairs—mainly the result of Bill Beck’s having just joined Barco literally days before the start of today’s Summit—the weapons brought to the game this time are the same, the most interesting new weapons in the video projection wars to appear on the scene in years—and deserving of a full airing for this InfoComm audience.
Remember, this battle is not about “hybrid” laser/LED projectors that put out 1K to 7K lumens. We’re talking about huge milestones, with a single projector putting out up to 60K lumens or more and with the projectors designed for smaller screens (NEC) cranking out 20K-plus lumens.
Richard McPherson of NEC Display Solutions—in the unique position of representing a product very different than the much brighter and much pricier Barco and Christie offerings—again stressed the compact size of the new NEC Phosphor Laser projector, its lower cost, and its regulatory-friendly status. In April McPherson said that he thinks NEC will ship “a few hundred” units this year. He reiterated that again today. In Q&A, McPherson said that they are “looking in particular at the Latin American market for growth.”
Don Shaw of Christie explained the advantages of the 6P laser setup, that allows for a 42 percent to 45 percent light efficiency (amount of light leaving the “lamp” that actually makes it through the 3D filtering to land on the screen). Shaw stuck to his two-projectors for 3D guns today, as Christie and Barco have been sparring fairly publicly for the several months over the one (Barco) vs. two (Christie) 3D configuration.
Bill Beck of Barco, being a Barco employee for days only, gave a more 40,000 feet assessment of the market and the technology. Beck explained that the six primary Barco Laser 3D projector solution saves the cost of 60 lamps over life of a projector
60K lumen. This is a 6-P laser configuration that’s coupled with a Dolby 3D color separation system. Barco is stressing a one-projector 3D solution (left and right eye sequential images). He said that the Barco projector can go 30,000 hours, at 80 percent of max power. (A single Barco DP4K-60L projector can do up to 24-meter-wide screens with 7fL 3D, with 1.8 gain; or up to 17 meter wide screens with 14fL, with 1.8 gain.)
In fact, all the presenters touched on the lifespan question, and while the math is a bit different for each solution, all the projector manufactures are taking advantage of laser’s super-high-lumen output by actually dialing down that output in favor of brightness consistency over the life of the projector. For example, NEC’s McPHerson said, “65 percent of output is all you need for a 20ft. screen … and you can keep that going forward for the lifespan.”
And when NEC says its projector has a 20K0hour lifespan, what that means is that after 20,000 hours, you still have 50 percent of brightness left.
When Bill Beck of Barco, referring to different ratings floating around, asked Don Shaw of Christie, “Is the Christie projector 72K lumen or 60K lumen?” Shaw replied, “We’re saying 60K … but we can pump more … I’ve seen systems with 100K lumens.” Shaw was confirming what all the big three manufacturers are doing: using a kind of sliding lumens output, depending on the need of the room, to get maximum efficiency not just max lumens.
Since NAB, when Barco announced that it had secured sales of some DP4K-60L projectors to CineMark and Santikos in the U.S. and Kinepolis in Europe, and Christie announced that was shipping some laser projectors to pro AV market customers, Christie has just announced that it will be installing a 6P laser projection system at Moody Gardens theme park in Galveston, Texas. According to Christie the “audience will be the first to experience 4K-resolution 3D 6P laser digital projection on a giant screen.”
Barco, Christie, and NEC will no doubt be doing a combination of public and private showings of high-lumen laser projectors at InfoComm in Las Vegas. If you have not seen one of these big guns, seek one out and be prepared to be amazed.
