Self-cleaning touch screens may appear in the near future.

The touchscreen display of a mobile phone or tablet is a great invention that has made life easier for many of us. People who prefer mobile devices with a keyboard are getting smaller. But there are a lot of smartphones with touch screens. In general, this is good, but there is a significant drawback for this display - marcos.



If you actively use a smartphone, then after a short time it will be similar to what we see in the preview photo. In addition to the non-aesthetic appearance, such a display can be a real horror for people who are afraid of viruses. For a long time scientists have shown that keyboards and mobile phones are one of the dirtiest things in an office or apartment.

But there is a way out, scientists say. And this output can be based on the specific substance - titanium dioxide. In the sun, the compound begins to "produce" free radicals that destroy the walls of bacteria cells and microscopic fungi. In addition, the same substance destroys fingerprints, removing greasy stains from displays.



True, in order for all this work to be done it takes about an hour (time depends on the level of contamination of the display). And this time the smartphone should lie in the sun. Now scientists are looking for a connection that can work in a similar way from the light of street lamps. I would like to hope that soon we will receive a new type of touch screen, which will no longer annoy us with fingerprints on the surface.
