At last! Scientists create unbreakable smartphone screen


British scientists have developed an unbreakable smartphone screen.

The pioneering touch screen is made from a newly created material which is extremely flexible and strong and which should put an end of the misery of cracking your smartphone screen.

Not only will the new screens help to save users money in repairs and replacements, it can also be manufactured at just a fifth of the cost of current smartphone screens.

Scientists say the new technology could be available on handsets from as early as 2018 and could send the prices of smartphones, tablets and TVs tumbling.

The electrodes found in smartphone screens currently are made from a rare and expensive material called indium tin oxide.

However, indium is in short supply and stocks are close to running out, which has caused a global race to try and find a new material that manufacturers can use in electronic devices.

Now, a team of British scientists have found some hybrid materials that are able to conduct electricity.

The new electrodes are created from graphene and silver nanowires and form the building blocks of the new screens.

Graphene is an excellent conductor of electricity and silver nanowire is around 1/10,000 the width of a single human hair.

By combining the two materials, scientists have been able to create a film that is able to conduct electricity but which is also extremely flexible and is unable to crack or break.

And at around 350 baht per square metre compare to 1,800 baht, the new material is considerably cheaper than using indium tin oxide.

The new material has been developed by scientists from the University of Sussex in partnership Oxfordshire based electronics firm M-SOLV.

The findings of the new study titled: Finite-size scaling in silver nanowire film: design considerations for practical devices, have been published in the journal Nanoscale.
