A team of researchers at the Massachusetts Institute of Technology ( MIT ), in Cambridge, led by professors, Marin Soljaèiæ and Ioannis Giannopoulos, announced the development of a new type of transparent screenς.
The new feature is achieved by incorporating nanoparticles into a transparent polymer or plastic. These particles are better suited to reflecting light by striking them at certain wavelengths, which means they can, for example, appear to reflect the blue color as shown above.
All other wavelengths will pass through the screen unimpeded, without being reflected off the nanoparticles. The team admits the system is very simple at this point, and is rather early stage, but says early results are very encouraging, adding that further development could lead to transparent displays that would be able to use more colors.
"This is a very clever idea, using the spectrally selective scattering properties of nanoparticles, to create a transparent screen. I think it's a beautiful demonstration", comments the electrician professor mechanical Mr. Shanhui Fan of Stanford University, who was not involved in this research.
