Is There A Laser In Your Future?
Although laser imaging technology has been around for a few years, we haven't seen it in a projection TV application ?until now.
So, is there a laser projection engine in your future? That depends. You'll probably see LEDs pick up the slack sooner, as short-arc mercury lamps are phased out. It's true that LEDs aren't terribly energy-efficient, but they don't suffer from speckle, and are naturally diffuse illuminants with specific color wavelengths. Four companies showed LED rear-projection TVs at CES 2006, and that's four times as many that showed a laser product.
