Folding phones such as the Samsung Galaxy Fold still have to deal with the problem of a lack of screen durability because of the polymer plastic material on its outer layer. Compared with glass, plastic is resistant to bends, but it is not resistant to scratching. The good news is that a manufacturer called Akhan Semiconductor is looking to use one of the hardest materials on the planet to create the outer screen of a folding smartphone.

Bendable glass, known as the industry’s “holy grail.” Without a strong top layer, pressure, water, dust, sharp objects, etc. can easily cause the folding screen intelligent machine internal structure rupture.
At CES,media found that a company gave a special answer: diamond glass. However, Adam Khan, founder and CEO of Akhan Semiconductor, which is developing Miraj diamond glass, says:
“The nanodiamond itself is semi-flexible and we can use it to cover the flexible screen. But to create a fully collapsible diamond glass, there is still a need to overcome manufacturing challenges.”

Based on nanodiamond materials, the company made Miraj diamond glass in the laboratory. It is only 100 nm (one-tenth of a millionth of hair) and can be sprayed on the corresponding surface.
If successfully commercialized, the technology could help move folding-screen devices away from the “toy” nature and into a more serious market.

It should be noted that A Semiconductor is not the only company dedicated to providing stronger materials for collapsible phones, such as Gorilla Glass maker Corning.
As demonstrated, Corning’s new glass can be folded without cracking, but is still under development and cannot be commercially sold. But anyway, we’re expecting to see more folding phones in 2020.
