One of the issues with foldables is creasing, and LG has developed a new material that addresses this and the foldable screen's durability. The company's chemical branch made a cover window, a protective part that lies on top of the display, designed to be as tough as glass and as flexible as plastic.
LG created this cover with a special coating on top of a thin polyethylene terephthalate (PET) plastic film. This material is said to be sturdier and more flexible than the existing crop of polyimide film and tempered glass-based solutions.
According to the company, the "real folding window" solution can hold its shape for more than 200,000 folds and unfolds, translating to roughly five years of use. LG plans to mass produce this material in 2022, with full-scale production in 2023. It envisions the use of this material in laptops and tablets, too.
