MIT researchers clarify things with new transparent display technology

  Researchers at MIT have come up with a new system that is low-cost and offers a wide angle of view with the projected image appearing on the transparent material itself.

The fact that OLED and LCD transparent displays integrate the necessary electronics directly into the transparent material limits their transparency and makes them complex and expensive. In comparison, the new system developed at MIT embeds only nanoparticles in the transparent material. These nanoparticles are tuned to scatter light of very specific wavelengths, or colors. When this particular wavelength of light is projected onto the display, it is scattered rather than passing through like all other wavelengths.
