Mitsubishi's new TV is the first to use laser light, which produces exceptionally vivid color. Like some existing TVs, Mitsubishi's uses an array of tiny, movable mirrors; red, blue, and green light beams strike the mirrors and are reflected onto the screen in different combinations. But because laser light is so pure--all its photons have exactly the same wavelength--the color combinations can be much more precise. The TV will be on the market by the end of the year."
