Now, stick-on screen that can turn any window into movie display
Scientists have created a transparent plastic screen which they say could turn any window into a display for moving images.
The screens are made by adding tiny nanoparticles that reflect blue light into a liquid polymer, and can be stuck on to any window, the BBC reported.
The nanoparticles create the transparency as they are invisible to humans, and images projected in blue light show up.
The screen created by researchers led by Chia Wei Hsu, a graduate student from MIT and Harvard University, US, could be used to host advertisements on shop windows or for office presentations.
The study was published in the journal Nature Communications.
