Mitsubishi has developed yet another twist on the flat panel television, according to a report in Tech-On. Instead of using LEDs as a solid-state light source for an LCD panel, the design uses a red laser along with a special, high-brightness, cyan LED. The combination of the two light sources create a mixed white light that reportedly has better color performance than the standard white LEDs or the combination of red-green-blue LEDs.

One advantage of this design is that it uses far fewer components than one that relies solely on LEDs. The red laser is about 10 times brighter, so you need one-tenth as many lasers as you would LEDs. This creates a challenge in the form of designing light guides that will mix the different-colored lights adequately, however.

This new backlight technology for LCD flat panels is not to be confused with the all-laser rear-projection HDTVs that Mitsubishi has been showing for several years.
