As makers of intelligent impact protective cases which are carefully integrated with advanced technology, we love exploring the concept of the latest stick-on transparent screen which can turn any window in to an image display! It’s a bit like a creating a projection on a window pane, or a large display for movies and has been designed and created by a group of scientists.
How is it Made?
According to the BBC, these transparent screens are created by adding a series of tiny nanoparticles that reflect blue light in to a liquid polymer formula. The microscopic nanoparticles are invisible to us humans which is what creates the transparent effect that we see. Nanoparticles, or Ultrafine particles, measure in at between 1 and 100 nanometers in size. These clever little particles are particularly useful for this project because they often possess unusual optical properties which are minute enough to confine their own electrons.
They’re incredibly easy to make by placing the nanoparticles in to the polymer before it becomes rigid, explains Wei Hsu, lead researcher.
How does it Work?
Transparent screens are no new concept, with developments such as Google Glass for example, but these products are time consuming to make and are expensive. The Stick-On screens are cheaper and faster to manufacture, avoiding the use of expensive technological equipment. Only a few 1000ths of a gram of nanoparticles are needed per square centimeter of each transparent stick-on screen.
At the moment only one colour can be displayed on these screens because each type of nanoparticle can only reflect one colour at a time. It is possible to have multi-colours but this would involve introducing different types of particles and the more nanoparticles present within the screen, the less the transparent illusion works and the more opaque the screen is.
What Could Stick-On Screens be used for?
The advancement of these easy-to-assemble screens opens up exciting prospects in a range of different fields. Imagine, for example that these transparent screens are stuck on shop windows, advertising products in the store and latest offers. Or perhaps they could be placed on to office windows and used to display important presentations. Because the stick-on screen is simply a plastic sheet which can be popped on to any surface, the opportunities are endless! What do you think the future holds for transparent stick-on screens?
