Technical News Office –If you think foldable screens are the latest and most advanced display technology around, then you should know about LG’s latest prototype. The company introduced the world’s first expandable display, which can expand up to 50% of its size. The screen presented by the company is 12 inches and can be stretched up to 18 inches.
What’s most impressive is that even after so much stretching, it is able to maintain high resolution of 100 pixels per inch and full RGB colors. If released after being fully extended, the screen returns to its original size (12 inches) without any damage. LG has redefined the definition of flexible display by introducing its latest prototype stretch display, capable of displaying full RGB colors at their maximum stretch.
LG Display describes it as the company’s “ultimate display technology.” Currently, the definition of a flexible screen in the market is one or two foldable screens at most, as we have seen in current foldable smartphones. However, enlarging the screen by stretching it like rubber is revolutionary in many ways. LG Display claims it can be used across multiple industries, including “fashion, wearables, mobility and gaming.” According to the company, it could also find its place in the automotive and aeronautics sectors.
LG Display first introduced this display technology in 2020, when it was only expandable up to 20%. At the time, the company said the panel’s quality was comparable to a 40-inch 4K TV equipped with a pixel density of 100 ppi. LG Display claimed that the prototype could withstand repeated stretching up to 10,000 times.
Additionally, the display uses a micro-LED light source measuring just 40 micrometers. Apart from this, it is also said to be able to withstand extreme temperatures or external shocks etc. LG Display says the screen is built on a special silicone substrate that is also used for contact lenses. It features micro-LEDs connected via S-shaped springs instead of straight wires so they can stretch up to 50% without breaking.
