LG’s latest foldable display technology promises to reduce screen wrinkle

One of the problems with foldable smartphones is that the constant bending can leave a noticeable (and unsightly) streak in the screen. However, LG may have found a way to reduce that wrinkle.

On Tuesday, LG Chem, a subsidiary of LG Corporation(Opens in a new window) A new foldable screen that promises to be superior to other technologies on the market. It is hard as glass and as flexible as plastic. At the same time, the material is thin, resistant to cracking, and “significantly” reduces folding lines when compared to current display folding technologies.

The screen itself is supposed to be implemented as a “cover window” on top of an OLED panel that can protect the screen while still being clear enough to send out high-resolution images.

“The price competitiveness is superior compared to existing polyimide films, and due to its superior flexibility, the durability is perfectly maintained even when folded more than 200,000 times,” the company said. In addition, the screen can be bent inward and outward.

As part of the announcement, LG Chem showed some images of the display technology, which it dubbed “Real Folding Window”. But the company refrained from bending the screen entirely, so we’ll have to wait and see if the technology can really smooth out the wrinkle as advertised.

It is also important to note that LG Electronics itself has exited the mobile phone business. So we will probably never see a foldable phone with the LG brand name. However, the Korean group still sells components to various customers, including in the smartphone and PC industries. So there’s a chance we’ll see foldable display technology in consumer technology in the future.

“We will strengthen our partnerships with leading smartphone manufacturers and expand our market starting with mobile phones and moving into new foldable applications such as laptops and tablets,” added Mr. Chang Do Ki, Vice President of LG Chem.

The company plans to develop mass production capabilities for the screen cover output next year before beginning “large-scale product sales” in 2023.
