Jason Hartlove, CEO of Nanosys, met with me at CES to talk about the work he and his company is doing to make the colors of LED displays more colorful and attractive with process-ready technology that electronics and lighting companies can easily add to their current LED manufacturing lines. The trick is in nanotechnology, creating nanomaterials out of semiconductor materials to layer over blue LED lights (the most energy efficient LED color), forming better quality white LED light with a range of hues. And the result is far more vivid colors with the same energy efficiency of current LED technology. Using this nanotechnology, the company has figured out how to make LEDs of virtually any hue with a color saturation far greater than current LED-backlit LCD displays, and lighting that has warmer hues.
