larger-sized OLED displays to become feasible for the consumer market, Nanosys has stolen in and demonstrated a new LED coating technique that proposes to radically improve color saturation in LED-backlit screens. Based on standard blue LEDs -- the most efficient kind -- this works by applying nanoparticles to the light and thereby endowing it with the desired hue. While the nano-coating can make standalone LED lights far richer in color, the real potential is in its deployment in LED-backlit displays, such as those becoming dominant on laptops today. By employing a coated array of blue LEDs instead of the standard white stuff, this can deliver greater color saturation while fitting within the same energy profile of current LED tech. Products boasting Nanosys' new hotness are said to be coming out later this year, with some appropriate premium slapped on the price for the fancier output.
