William LaCourse, a professor at Alfred University, USA, has just revealed that the foldable iPhone can be launched in 2021. LaCourse also said that Corning, the manufacturer of Gorilla Glass protection for smartphones, is developing a product. for use on foldable devices and “will be available in less than a year”.
According to LaCourse, the new glass will be sold in about 12-18 months. This means that Samsung Galaxy Fold 2 and some other folding screen smartphones will soon be equipped with this technology.
Currently, most folding screen smartphones being sold on the market are only equipped with plastic protection. This makes them have many problems with durability and stability during use. Tempered glass is expected to be the “savior” of these models.
In early 2019, The Verge reported that Corning is developing a new bendable Gorilla Glass that can be used with foldable smartphones.
In an interview with Wired, Corning Vice President John Bayne said the biggest challenge was to create a glass thin enough to bend but still not lose the resilience needed to protect the screen.
In fact, Corning has successfully fabricated a glass with a thickness of 0.1 mm and can bend with an arc radius of 5 mm. However, they cannot be used on folding screen smartphones due to their low durability.
In a file titled “Electronic devices with flexible displays and hinges,” published by the US Patent and Trademark Office, Apple revealed the design of a foldable smartphone.
Accordingly, Apple will bend the screen in a way that makes the middle part slightly bent out before folding the screen. This allows the main parts and the edges of the screen to interact flexibly with each other without being affected by the curved area while allowing the curved part to operate at an extended radius, minimizing the pressure of parts.
