Evident licenses nanocrystal patents from Philips

A licensing agreement with Philips will enable Evident to make and sell LEDs that use semiconductor nanocrystals instead of phosphors for color conversion.

Evident Technologies, Inc, a Try, NY-based company that develops and commercializes technology based on semiconductor nanocrystals, has signed a non-exclusive licensing agreement with Philips Electronics. This will pave the way for Evident to commercialize nanocrystal-based LEDs.

Evident Technologies intends to immediately launch a new line of low-power LEDs and LED-based products that use semiconductor nanocrystals as a phosphor.

"LEDs last longer and are much more efficient than incandescent lights but are limited to only a few colors," said Clint Ballinger, CEO of Evident Technologies. "We are excited about this licensing agreement and leveraging our technology to bring additional colors to these light sources."

LED chips are fundamentally constrained to emit only a single color of light. Most current white LEDs use phosphors to convert blue LED chips into "white" or other colors. However, the underlying phosphor technology can limit the range of colors that are obtainable, says Evident, while semiconductor nanocrystal technology removes these color limitations.

Founded in 2000, Evident has been developing semiconductor nanocrystal technology for years and plans to immediately launch commercial LED products based on this technology.

"We have long believed that there is a market for semiconductor nanocrystal technology and we are looking forward to the technology being commercialized," said Dave Barnes, Senior IP Council at Philips.

"The LED industry seems eager to embrace this technology," said Dave Duncan, COO of Evident Technologies. "Our new line of LED products will enable us to enter the retail market as well, making them the world's first consumer products based on semiconductor nanocrystals."
