LG Real Folding Window Display Technology
LG Chem’s ‘Real Folding Window’ display technology is unlike any other, as this specially developed coating material is applied to make the surface as hard as glass, while the folding parts remain as flexible as plastic. More specifically, it differs from the polyimide films and tempered glass-type materials of today because the cover window applied on LG Chem’s new coating technologies maximize flexibility, while also providing optimized solutions for foldable phones, especially where the screen creases.

This new material measures just a few dozen micrometers (㎛) thick on both sides of PET film, which is a type of thin plastic, to enhance heat-resistance as well as strengthen the mechanical properties of plastic materials. As you can see, it’s far thinner compared to existing tempered glass and has the same hardness, but without the risk of cracking. Compared to existing polyimide film, the Real Folding Window’s flexibility and durability is maintained completely even when being folded more than 200,000 times.
