Engineers have developed ultrathin, flexible, and cheap displays for future smartphones

A new kind of electronic material developed in Australia. It responds to touch, bends and thus a hundred times thinner than current screens for smartphones. The main material is already widely used in industry, and the screens can be printed in large sheets, like Newspapers.

Breakthrough in electronics was done by specialists RMIT University: they have created a flexible and thin display devices of the future. And not just smartphones – to print the screen are huge leaves, says the New Atlas.

Features of the development

The basis of the invention the material that is widely used in modern touch screens the indium-tin oxide. It is transparent with high conductivity, but too fragile. Therefore, the researchers decided to give it plasticity, as well as to reduce the thickness.

We took the old stuff and redid it from the inside out to create a new version that is much thinner and more flexible. It can bend, twist, and it is much cheaper than current touch screens with their slow and expensive methods of production,
– said the chief developer Torben the day.

How it works

The new material is made in a liquid format printing. The alloy indium-tin is heated to 200ΒΊ C, it becomes liquid and it rolled on the surface of the thin layer. Sheets with a thickness of a few nanometers consist of the same chemicals as regular indium-tin oxide, but they have a different crystal structure. She gives the material unique properties.

The main advantage of the material flexibility but also of note is transparency: it absorbs only 0.7% of the light, in contrast to 10% for standard glass.

This means that smartphones with such a screen will spend less energy. The developers have done an experimental touch screen phone, but the material can be used for the production of solar cells, smart Windows, or other smart electronic devices.
