3D and HD Drive Demand for Ultra-Bright Large Venue Projectors
Face it: Living large is everyone’s goal, whether you’re talking lifestyle or AV aspirations. And as clients’ visions grow in scope, not surprisingly, there’s an increasingly wide array of large venue projector (LVP) tools at the ready to accommodate them.
The new and improved show at Georgia’s famed Stone Mountain relies on six Barco FLM HD20 projectors to create a “virtual skin” on the 825-foot-tall granite outcropping. Three Barco High End Systems’ (HES) Axon Media Servers and driven by an HES Road Hog Full Boar console enable the creation of the edge-blended 3D video projections that virtually simulate a 5,500-inch HD resolution TV screen.
“Large,” of course, is a subjective term. The definition of what constitutes an LVP scenario can vary depending on whom you’re talking to, with everything from room capacity to the physical size of the accommodating venue being taken into account. At Digital Projection, for example, the initial criteria for large venue imagery is a screen size of about 12-foot surface width, with ambient light levels also a key consideration.
“Examples of venues that regularly need high-lumen projectors include houses of worship, which typically contain a good deal of ambient light due to large windows and open sanctuaries,” said Chuck Collins, VP of sales with Digital Projection. “Education environments as well, especially in auditoriums and collegiate environments where reading resource literature and viewing projected content typically commingle. Museums are an obvious choice, as there’s typically a good deal of peripheral light from other exhibits.”
As Barco sees it, there are clear forces powering the evolution in projectors capable of informing and/or entertaining the crowds that gather at a large venue. “There are two important trends that have driven the development of large venue projectors: brightness and resolution,” said Chris Colpaert, strategic marketing director for ProAV at Barco. “Over the last couple of years we have seen a big shift from 4:3 to HD (or WUXGA) resolution. Lots of rental companies have invested in HD cameras, and this has created a push for full HD resolution. Also in the ProAV world, full HD is becoming mainstream.
“Next to that, people continue to demand more light output: part of this can be explained by the popularity of 3D in digital cinema, which created the necessary buzz in ProAV as well,” Colpaert continued. “Due to the low [brightness] efficiency of the current 3D technology, it is required to use higher-brightness units. But we have also experienced a renewed interest in higherbrightness projection applications, such as outdoor building projection and multi-screen edge-blended projection applications.”
Mitsubishi sees LVP not in terms of venue size, but instead as any application requiring 6,000 lumens or brighter, noting that the increasing reliability and flexibility of big projectors apply to large-scale signage as well. “Newer projectors like the Mitsubishi 8000 series available today can run 24-7 and come with dual or quadruple lamps that ensure continuous operations,” explained James Chan, vice president, marketing for Mitsubishi. “Plus, the newer algorithms available that are built-in to projectors—allowing geometric corrections and edge blending—have enabled these devices to shine their bright images not only on the traditional flat screen, but on all sorts of creative surfaces.”
Cost effectiveness is always a factor for installers and clients, while manufacturers are striving harder to strike a balance between brightness and environmental impact. “As our customer base becomes more cost-conscious we have developed more cost-effective projectors,” Digital Projection’s Collins said. “We have specifically been working on advancements in our illumination technology. In the past, ‘high brightness’ meant the use of Xenon lamps were a necessity, but Xenon lamps are very expensive, and frankly, can be fairly tough on the environment. It’s true that Digital Projection still offers xenon-based projectors for our customers that need maximum brightness, but for our clients that need a more affordable high brightness alternative, our optical scientists in the U.K. have innovated a revolutionary new four-lamp illumination system.
A 777 flight simulator uses multiple Digital Projection dVision 30 projectors on a 180-degree curved screen.
“With our unique alignment of the quad lamp system,” Collins added, “we have created an incredibly compact projector chassis that captures unprecedented amounts of light to create a super-efficient 16,000-lumen projector. As we shrink our illumination technologies, we’re able to also shrink the overall footprint of our projectors, resulting in the ability to place brighter projectors like our Titan Quad projectors in small spaces.”
The benefits of these innovations spill off the projection surface and affect the space an LVP is in, allowing clients to make more of their installations. “Higher resolution and higher brightness allows the consultant and installer to specify bigger screen sizes, with less projectors or wide-screen projections with less units,” said Colpeart of Barco. “This drives down the investment cost and the electricity cost. The total cost of operation (TCO) is also positively affected by the higher lamp lifetime of the Xenon lamps. More and more designers and consultants are going away from the traditional projection on screens: With high-resolution, highbrightness DLP projectors, the full room comes at your disposal and very immersive environments can be created.”
All of the above becomes crucial when clients have mission-critical applications like medical education. As Director of Education Technology for the University of Central Florida for 10 years, Ron Knappenberger specified LVP’s such as the Mitsubishi 8200 to make absolutely sure instructors’ messages were getting across. “When you’re dealing with cell structures and intricacies of the human body, you need to have sufficient resolution and brightness for good detail,” said Knappenberger, who now holds the post of integrated technologies project manager for Greenville Hospital Systems, Greenville, SC. “And in a large venue you want to make sure the LVP is bright enough without all the lights turned off, since not all class materials are projected all the time: Students also have to take notes, and see the instructor and the whiteboard in the front of the room.”
As Knappenberger pointed out, however, quantity is nothing without quality. “You need to make sure you have adequate detail when projecting to large venues. The LVP can be as big as it wants—but if what you see is not of sufficient quality, it will not work.”

“The key to increasing margin in any sale is to accessorize,” said Chuck Collins of Digital Projection. “As base as the comparison may seem, fast-food establishments have mastered the art of the accessorized sale, suggesting a customer try a specific new drink or ‘super-size’ a meal. The same goes with an AV transaction, and in our case a projector sale.” Accessories integrators can offer include enhanced warranty programs, rigging frames, external warp and blend devices, lamps, and ceiling mounts.
