LG has exited the smartphone market. But when it comes to displays, whether for smartphones or other product categories, its subsidiary LG Display is still among Samsung’s main competitors.
Naturally, LG therefore continues to be interested in foldable screens, and rollable screens. But besides that, the Korean company is also developing a completely different type of screen: elastic screens!
LG presents its elastic screen
In a press release, LG presents a brand new technology, that of elastic screens, or rather “stretchable”, if we want to respect the vocabulary used by the company.
Specifically, the screen developed by LG has a diagonal of 12 inches. But its characteristics make it possible to stretch this screen, up to 20% of its normal size. The screen can also be bent, or twisted, without causing damage. According to LG, this 20% expandability is an industry first.
“Based on a high-strength film-like substrate made of special silicon used in contact lenses, this 12-inch display features a rubber band-like flexibility that allows it to be stretched up to 14 inches. The free-form nature of the display provides a state-of-the-art solution surpassing existing foldable and rollable technology”can we read in the press release of the Korean company.
The screen (RGB, 100 ppi) does not use OLED technology, but rather micro-LED light sources. In order to improve the resistance of the circuit, LG uses an S-shaped cable system which supports repetitive deformations of the screen. The good resistance of LG’s elastic screen opens the way to many potential uses.
What will it be used for?
We do not know when this screen will be marketed (but it is envisaged by LG). In any case, according to the manufacturer, his invention is suitable for surfaces such as skin, clothing, or furniture. LG also thinks that this screen could be suitable for fields such as aeronautics or automotive.
“[…] this unique innovation expands the potential of display in various industries including fashion, apparel, mobility and gaming”also indicates the Korean company.
We can very well imagine future products using this technology. For example, instead of wearing a connected watch, we could one day use an elastic screen with an adhesive surface, to stick on the skin, to access notifications.
But it’s important to note that while LG has certainly achieved a technological feat, it’s not the only one working on elastic screens.
