New Tech For Hyper Color TV

(From Wired.com -- By Sean Captain)

Researchers in Switzerland are developing a new nano technology they claim will double the range of colors that future TVs can produce -- displaying every hue the human eye can see.

By comparison, most of today's TVs -- be they plasmas, LCDs or projectors -- display only about half the visible colors.

"Current displays do not faithfully reproduce the hues of blue one can see in the sky or in the sea," said MANUEL ASCHWANDEN, who developed the new technology with ANDREAS STEMMER at THE SWISS FEDERAL INSTITUTE OF TECHNOLOGY.

Their invention uses DIFFRACTION GRATING -- a series of fine parallel grooves -- bonded to a flexible material, known as an elastomer, that stretches when voltage is applied.

Most diffraction gratings are fixed. When white light hits the grating, it splits into a rainbow of its constituent colors.

A common example is the rainbow that shines off a CD or DVD -- fine pattern of data tracks, by coincidence, produces a diffraction grating.
