What to expect: LG Chem, a subsidiary of LG, thinks it's found a way to hide the frightening lines of clamshell phones, or at least less noticeable than current devices. This technology and other innovations could pave the way for the primary use of foldable form factors, especially as they promise to reduce an issue that appears largely as a disadvantage to the non-technical consumer.
One of the main problems engineers face when designing clamshells is how to keep the screen strong enough to maintain its structural integrity and the ability to create a clear image. Be. Until now, the heyday of materials science has allowed them to build devices with screens that can be bent in and out hundreds of thousands of times without difficulty, but the side effect is a wrinkle in the middle that never goes away.
LG Chem says it may have found a solution called a true folding window. This is basically a new type of foldable screen covers that can last as long as existing solutions are much thinner and therefore less prone to wrinkles in the area where the screen is folded. In addition, it is no different from the touch glass in non-Oysters phones.

The amazing material is a special coating developed on a thin film of polyethylene terephthalate (PET), which increases the mechanical and thermal resistance of the plastic. Although only a few micrometers thick (thinner than a human hair), the resulting screen coating is tough on glass and cheaper to make than polyamide-based solutions (not to be confused with polyamide). Over time, the company hopes to meet the general need for PET plastic films. LG Chem claims that the real foldable window can be folded at least 200,000 times without much damage. Wrinkles can still be created, but they should be seen a lot less than you get on current foldable smartphones, as one day it will suffice to fold the "line fold" screen into both the foldable and out layout. slowly. The bad news is that LG Chem is not expected to reach true mass production capabilities of foldable windows by 2022, with mass sales scheduled to begin in 2023. The good news is that we can expect this technology to appear in convertible laptops and tablets folding.
