While we all wait around for 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
