Prysm’s custom video walls use proprietary LPD technology
By Mark Dwortzan
After Amit Jain earned his first bachelor’s degree, in physics, chemistry, and math, in India, his older brother hired him to help out at the audiotape manufacturing company he owned in Kolkata. Despite knowing nothing about how to assemble audiotapes, Jain jumped right in and was soon running the factory floor.
Fast forward to 2005. When investors asked Jain and his business partner, Roger Hajjar (ENG’88), to shift from optical networking to large displays, they came up with a new display technology that wound up transforming the industry—despite the fact that neither had prior knowledge of the field.
Jain and Hajjar cofounded Prysm, Inc., and their new display technology laid the foundation for the Silicon Valley–based designer and manufacturer of video wall systems now used across the globe by leading technology, retail, financial services, and media companies, governments, and universities, among them Beijing TV, CNBC, General Electric, and ENG.
“I have learned to never be afraid of trying new things and to go with my gut,” says Jain, 53, now Prysm CEO (Hajjar is CTO). “When we started Prysm, Roger and I had no fear of entering a new industry and no baggage from previous companies on what couldn’t be done—just ideas that could be applied in a new context. Within 18 months we came up with the concept for a new display technology, built a prototype, and shipped our first product.”
Today Prysm designs, assembles, installs, and provides software support for large, modular, interactive video walls of nearly any size, brightness, or resolution, customized to users’ needs, as well as 117-inch and 190-inch standard video walls used in collaboration rooms. The custom video walls enable architects, designers, and brand managers to provide unique, engaging, immersive experiences in lobbies, conference centers, control rooms, stores, and other environments. The collaborative walls empower teams in multiple locations to boost their productivity through real-time interactions, whether through touch or gesture, or by posting, sharing, and editing content uploaded from smartphones, tablets, or other mobile devices.
At the heart of Prysm’s video walls is the company’s proprietary laser phosphor display (LPD) technology, which features a solid-state ultraviolet laser engine, phosphor panel, and advanced optics. Mirrors direct beams from the laser engine across the phosphor panel, which in turn emits red, green, or blue light to form image pixels. The process occurs on multiple 25-inch tiles that fit together to make up a single integrated wall. Compared to conventional LED- and LCD-based technologies, LPD video walls deliver superior image quality, viewing angles, energy efficiency, and environmental impact—resulting in a lower ownership cost. With an an eco-friendly manufacturing process and nontoxic materials and requiring no consumables, they use up to 75 percent less energy than competing large-format display technologies and give off far less heat, eliminating the need for electrical system or HVAC upgrades.
“The Prysm video wall…delivers astounding image quality and ultrawide 178-degree viewing angles,” says Yao Hong, a sales director at the State Grid Corporation of China, which uses a curved, 80-foot-wide-by-11-foot-high wall to monitor the electrical grid system of China’s Jiangsu province. “These attributes combined with the tremendous scalability of LPD technology provide an ideal display solution for the command and control environment.”
Chris Van Name, a regional vice president at Time Warner Cable, chose Prysm to impress customers and minimize environmental impact. “Prysm’s video wall creates a significant ‘wow’ factor for any customer visiting our store and enables us to showcase our technologies in TV, broadband internet, and digital phone in a brilliant and beautiful fashion,” he says.
For Jain, Prysm represents the pinnacle of a 20-year career of growing successful technology-related businesses. Before cofounding Prysm, he was CEO of Bigbear Network and cofounder and CEO of Versatile Optical Networks, which was acquired by Vitesse Semiconductor Corporation; he led the Vitesse Optical Systems Division as vice president and general manager. Previously, he had held several management positions in start-ups and large companies, such as Terastor, Optex Communications, and Digital Equipment Corporation.
Throughout his career, Jain has drawn on expertise in both engineering and business and on lessons learned from an extended family, many also entrepreneurs. While working for his brother in the audiotape business, he imagined inventing technologies rather than just assembling them on the factory floor, so he came to ENG in 1983 to earn a second bachelor’s degree, in electrical engineering.
He learned not only engineering, but also how to communicate effectively to large groups as the first undergraduate teaching assistant of Kenneth Lutchen, a biomedical engineering professor at the time and now dean of ENG.
“Because I already had a bachelor’s degree, Ken gave me the opportunity to teach classes while still an undergraduate,” recalls Jain. “As I faced up to 40 friends and peers, I learned how to explain complex ideas clearly and concisely.”
Fortunately, he had already developed a penetrating voice, capable of drawing attention. “My projectile voice comes from survival of the fittest,” he says. “I have 48 cousins and am second from the bottom in age, so you needed a powerful voice to get your point across.”
After earning both undergrad and grad degrees at BU and an MBA at the University of Maryland, Jain became well-versed in the technological, communications, entrepreneurial, and other skills that are the hallmark of the societal engineer (basically, one who has a sense of purpose and appreciation for how engineering education and its experiences are superior foundations for improving society), a concept he embraces both as CEO of Prysm and as a member of the ENG Dean’s Leadership Advisory Board.
His close relationships with his family and his 200-plus employees, he says, are critical to his success and those relationships are anchored by his religion, Jainism, some of whose tenets—Don’t kill. Ask forgiveness. Respect different views—appear on a card he carries in his pocket.
“Everyone has a viewpoint,” he says. “The important thing is to listen to all views in order to make the right decisions.”
