Novalux To Demonstrate First Laser-Based LCD-TV BLU

Novalux, Inc., developer of Necsel™ laser technology, will reveal its latest proof-of-concept demos during the 2007. The demos show how Necsel technology is leading a new area in lighting and display applications. They include the first laser LCD-TV Back Light Unit (BLU) and laser architectural tube lighting, along with the most recent developments in laser high-definition projection TV (HDTV).

“Over the past two years Novalux’s focus has been on Necsel for projection displays. We’re now moving to manufacture lasers for those applications,” said Greg Niven, Novalux executive vice president of marketing. “Simultaneously, we’re expanding Necsel development in a number of other markets. During SID we’re planning to show some of these early concept demos. The first is a laser LCD-TV BLU — it’s a great example of how Necsel technology could enable better LCD TV performance, lower cost, and, of course, provide superior laser color. We’re also demonstrating laser tube lighting designed to replace neon signs in the multi-billion-dollar specialty lighting market. For sign replacement, Necsel could allow safer, lower cost, brighter tube lighting than any other technology available.”

Necsel lasers are ideal for LCD-TV BLUs because they replace all Cold Cathode Fluorescent Lamps (CCFLs) and/or LEDs, simplify the necessary electronics, and eliminate the need for color filters — drastically reducing device cost. Necsel laser LCD TVs can also be edge-lit, dramatically reducing panel thickness. And laser color could allow future LCD TV users to experience the wide-color-gamut content slated for movies and gaming.

As a replacement for neon sign tube lighting, Necsel also provides a host of advantages. Said Niven, “Neon is falling out of favor due to the fire hazard, high voltage, and handling difficulties — some municipalities have gone so far as to ban it from the building codes. The alternative LED tube lighting is expensive, has poor reliability, and is only available in a few colors.” Necsel lasers could provide a safe, cost-effective, long lifetime method for illuminating light fibers. Moreover, Necsel’s unlimited colors could be tailored for each application or a particular customer to create a truly “neon” effect.
