Foldable screen display technology for mobile

A team from LG Chem announced on LG’s Newsroom webpage that the company has developed a new type of foldable screen display technology for use in mobile devices. As part of the announcement, LG officials say the new material is as hard as glass but as bendable as plastic.

Foldable phones are still relatively new to the smartphone market and still suffer from new product issues – in this case, issues include durability and crack lines in bend sites. In its announcement, LG claims to have improved durability with its new technology while reducing crack lines.

The real folding window is a new type of coating – its use is to apply it to both sides of the PET film that covers the folding screen. The coating would be no more than a few tens of micrometers thick, which would make it barely noticeable. LG’s team notes that it’s thinner than the tempered glass currently used for foldable phones, but won’t crack; thus, it can be considered as an improvement in the shock resistance of the phone.

LG announced last spring that it will no longer manufacture or sell smartphones, but that the company will focus on developing and licensing smartphones made by other companies. So LG won’t produce phones with the new coating; it will sell the technology to customers who the company says have already expressed an interest in using it. LG also says its Real Folding Window technology will be competitively priced against polyimide films. They also claim that they have made significant progress in reducing crack lines – they claim that their new material was found to be free of crack lines after being bent 200,000 times. LG also notes that, unlike competitors, its technology can be used on both folding and folding phones.

The announcement ends with a statement that the company plans to begin mass production of its Real Folding Window technology by 2022, with full-scale production beginning the following year. They also note that they are working on a coating that will not require PET film.
