This flat screen twists and stretches in all directions

LG Display has unveiled the world’s first high-resolution stretchable display. This ultra-thin panel, designed from a silicon substrate, can twist but above all stretch with a gain of 10% display. It will take two to three years for the first devices to be equipped with it. There is even mention of an application on… the skin!

After the foldable or curved screen, place on the screen ” that we twist and stretch in all directions “. This is the technological prowess achieved by LG with a flexible 12-inch screen that can be twisted like a towel or spread like chewing gum or pizza dough. It’s hardly exaggerated since the display area can reach 14 inches! According to LG, this gives a 20% increase.

The Korean brand is not the first to make such a demonstration, but its ultra-thin screen is the most successful, and the definition of the image is more than correct since LG announces 100 dpi with a display colorcolor RGB. For this, the panel uses a micro-LED light source with a pitch of pixelpixel less than 40 μm to guarantee a high level of longevity and withstand impacts.

Soon on the skin?

Based on a substratesubstrate highly resistant in siliconsilicon special usually used in contact lensescontact lenses, this 12-inch expandable display boasts elastic-like flexibility and the design is simply reminiscent of cling film. Unlike the conventional linear wired system, the S-shaped structure can withstand repetitive changes in its shape, hence the possibility of twisting it even if, admittedly, this is of little interest.

For the moment, it remains a prototype but it is currently the most successful and LG’s R&D department is targeting the middle of the decade for a launch with the insertion of this surface on connected objects such as clothing and connected bracelets. or even ” skin and furniture “says the manufacturer.

For years, South Korean manufacturers Samsung and LG have been fighting a merciless battle over mattermatter of technology and innovation in the television, smartphone and household appliance sectors. This struggle has allowed them to become one of the largest manufacturers in the world, and today, one of their battles is in foldable screens.

Samsung has taken a big lead with several models, released in the Fold range, with a foldable screen reinforced by a layer of protective film. After a few hiccups at startup, this panel has proven itself, and the latest Galaxy Fold 3 is a real success. On the side of LG, we decided to go even further with an improved plastic, called Real Folding Windowwhich could be translated as “real foldable slab”.

Foldable in both directions

According to the LG Chem press release, a materialmaterial made of polyester film (PETPET) covers each side of the glass. This coating is enough to maximize flexibility of the screen, while being thinner than ” the heat-tempered glassheat-tempered glass current “. All with the same solidity and the same resistanceresistance to scratches and cracks.

The slab is covered with a few tens of micrometers of this new material to increase its heat resistance, and the real advantage over Samsung panels and Chinese competitors is that it can bend both outwards and inwards. LG plans to launch production of this type of screen in 2022, with the desire to unveil its first consumer products in 2023. It will not necessarily be smartphones since the South Korean manufacturer plans to equip them laptops and tabletstablets.
