Prysm, Maker of Laser Screens, Quietly Breeds a Large-Display Revolution in Concord

stacked and tiled up to any required size. The biggest display the startup has attempted to assemble to date is a 12-by-12 array of Maui screens with a total diagonal measurement of 300 inches, or 25 feet. The challenge of going bigger isn’t really a mechanical one right now, Tan says—it’s more a matter of improving the tiling software that takes a single video signal and spreads it across the 12-by-12 array’s 144 separate screens.

Prysm displays in a public space“You have to prove mechanically that the screens can go together, and electrically that you can take a signal, split it up, recombine, and have it look good,” says Tan. “If we put some effort into it, we can make something much bigger. We’d just have to scale the tiling engine and work on the packaging a bit, but basically it’s like stacking Lego blocks.”

With plenty of expertise on hand—including seven staffers with PhDs in chemistry, physics, and optics, along with others who have spent time at legendary New England technology organizations like DEC, Polaroid, and MIT’s Lincoln Laboratory—Tan seems confident that the startup can figure out how to put all the pieces together.

“Having the capability and knowledge is one thing, but you’ve also got to deliver, and many of us have worked in companies that have delivered product to the marketplace,” Tan says. “We’re all good problem solvers. If you ask why Japan Inc. didn’t come up with [the laser phosphor display], I think it’s because you can get optimized around a space and forget to take a step back. I think this is where the U.S. is terrific. You have smart, playful engineers who say, ‘Why not?'”

Between 2007 and 2014, I was a staff editor for Xconomy in Boston and San Francisco. Since 2008 I've been writing a weekly opinion/review column called VOX: The Voice of Xperience. (From 2008 to 2013 the column was known as World Wide Wade.) I've been writing about science and technology professionally since 1994. Before joining Xconomy in 2007, I was a staff member at MIT’s Technology Review from 2001 to 2006, serving as senior editor, San Francisco bureau chief, and executive editor of TechnologyReview.com. Before that, I was the Boston bureau reporter for Science, managing editor of supercomputing publications at NASA Ames Research Center, and Web editor at e-book pioneer NuvoMedia. I have a B.A. in the history of science from Harvard College and a PhD in the history and social study of science and technology from MIT. I've published articles in Science, Technology Review, IEEE Spectrum, Encyclopaedia Brittanica, Technology and Culture, Alaska Airlines Magazine, and World Business, and I've been a guest of NPR, CNN, CNBC, NECN, WGBH and the PBS NewsHour. I'm a frequent conference participant and enjoy opportunities to moderate panel discussions and on-stage chats.
