Sci-fi glass displays become reality

While it might sound like science fiction to some people, it's not sci-fi to Ted Sun.

"I see in movies like Avatar and Minority Report that people put information on glass," Sun said. "This technology can do it now."

Sun is talking about Media Glass, an invention that combines an invisible laser beam with a thin nano-technology film. One layer turns red in a spot of laser light, while another turns green and a third turns blue. Each layer is made of particles so tiny that visible light passes right through them.

If you coated your car with this film, it could display a see-through dashboard or even a GPS map.

The image is being drawn by a laser beam, but the colors that are visible is not the color of the laser. The laser light by itself is invisible; the glow that is visible is the nano-material phosphor responding to the laser light.

The coating can be put on any material, whether it's clear or not. Since it is completely absorbed by the coating, the laser beam doesn't pass through. In fact, the film could be built right into an automobile's windshield.
