In April we met the LG withdrawal of the mobile market. From then on, they stopped making smartphones under their own brand. Despite that, they have not completely detached themselves from the area either.
LG Chem, a division of the South Korean company dedicated to the development of engineering solutions through chemistry, presented a new material for the manufacture of flexible screens, whose characteristics ensure greater resistance and durability compared to the materials used today in mobile phones.
LG developed new technology for flexible displays
Through a release press release, LG unveiled its new display material, called Real Folding Window. Billed as a solid, durable and tough alternative to glass, this compound is based on a PET plastic film just a few dozen microns thick, coated to improve its response to heat.
It is important to specify that the development presented does not constitute a screen in itself, but only a part of it. The component in question is the area that comes into direct contact with the user.
This new material, according to the South Korean company after its development, combines the flexibility of plastic with the resistance of glass and presents a durability higher than the average known in the industry today. As noted, Real Folding Window guarantees integrity that spans more than 200,000 folds, the equivalent of 5 years of regular use, according to its estimates.
“Unlike existing polyimide films and tempered glass-type materials, the cover window that applied LG Chem’s new coating technologies will maximize flexibility, while providing optimized solutions for folding phones, such as making improvements to chronic problems such as crease impressions on the connecting part of the screen »a company spokesperson said in the aforementioned statement.
Mobile phones with a folding screen are growing examples in this market segment. Huawei and Samsung are part of the manufacturers that have promoted these models in recent times, among others.
The experience left by the expansion of these specimens, even with new models such as the Samsung Galaxy Z Fold 3, has shown that the materials currently used in their flexible screens are fragile, accumulating in some cases crease marks or another major class of deterioration. in its hinge area.
Although a material of this type could eventually be used in a wide variety of hardware, from LG they assure that their target segment is the mobile sector. “We will strengthen our partnerships with leading companies in the smartphone industry and expand our market starting with mobiles and moving to new foldable applications such as laptops and tablets.”said Chang Do Ki, leader of LG Chem’s materials division.
The production of this material is projected massively for next year. Only in 2023, if the schedule presented is not postponed, would new devices that use this material technology begin to appear on their screens.
While thinking about the deployment of this new technology, LG Chem is already working on an improved version of it, which would dispense with the protective plastic film to perform its same functions.
From LG they contemplate with optimism this path that they are opening within the hardware route of the next few years. Citing a global survey by Omdia, they noted that it expects the foldable phone market to grow from 3.5 million units in 2020 to 50 million in 2026.
