Prysm Inc., a 5-year old California company with manufacturing operations in Concord, is having its official coming-out party for its display technology, which the company says is much more efficient than that used in high-definition displays today.
The San Jose-based company is developing technology it terms Laser Phosphor Display (LPD), adding to the acronym soup used in the HD industry already — LED, LCD and DLP. Prysm is targeting large format displays used in commercial venues and sports arenas, instead of the home display market.
According to Prysm officials, the LPD technology uses up to 75 percent less power than other HD display technologies, including plasma. The LPDs are also made using low-impact manufacturing processes and non-toxic materials, making them greener than some technologies currently in use, the company said.
The LPD technology is not unlike old-fashioned tube TVs, wherein electron beams are used to excite phosphor dots to emit light. In Prysm’s tech, a laser engine — using low-power draw, long-life semiconductor lasers — is used to excite a phosphor screen.
Prysm was founded in 2005 as Spudnik by Amit Jain and Roger Hajjar. Both men are graduates of Boston University’s College of Engineering and sit on the board of BU’s College of Engineering West Coast Alumni Leadership Council. The company has more than 100 employees, with about 30 in Concord, according to a spokesperson.
