Those mad scientists at Mitsubishi have built the ultimate entertainment weapon—the laser TV! Lasers shooting out of a television screen isnt as scary as it may sound. But it does have one big benefit-color.

Lasers can be tuned to the exact wavelength of light you like—down to the nanometer. So TV makers can produce the ideal shades of red, green, and blue to produce the best colors possibly. Mitsubishi claims this allows them to reproduce about 80 percent of all the colors humans can see—versus about 40 percent for other TVs.

It takes lots of light to deliver bright, crisp images on your rear-projection TV, but that same light leaks through to the screen during dark, Perfect Storm—style gloomy scenes, hindering detail. To darken the blacks, a growing number of LCD and DLP rear-projection-TV manufacturers are turning to mechanical apertures that can limit the amount of light that reaches the screen. HP, Toshiba and Sony, among others, are using a dynamic iris, which automatically narrows like a camera’s aperture to reduce the amount of stray light.
