The prototype with a diagonal of 12-18 inches retains the full RGB color gamut and excellent resolution, despite various manipulations with it.
LG demonstrated several possible uses, including a car display that can change shape and be controlled by hand gestures, and a wearable screen that provides firefighters with real-time information. Interesting Engineering writes about it.
LG presents a revolutionary information display technology: "the world's first stretchable display" capable of expanding by 50%.
"We will continue to build a sustainable future display ecosystem through close collaboration between South Korean industry, academia and research stakeholders," LG Display CTO and Executive Vice President Soo Eun Yoon said during the event.
This stretchable display can twist and stretch into different shapes, unlike standard flexible displays that can simply be bent or folded. The technology is opening up new opportunities in a number of industries, including wearables, fashion and the automotive industry.
Thanks to the resolution of 100 pixels per inch, the new 12-inch display can be expanded to 18 inches, while providing a clear and colorful image. The current version offers a significant improvement, increasing the stretch factor by 50% compared to LG's initial 2022 prototype, which could only stretch by 20%.
"The maximum elongation factor of the new panel has more than doubled — from 20% to 50%," the press release reads.
According to LG, new methods of connecting displays and a unique silicon material used in contact lenses are among the advanced technologies that made it possible to achieve this result. The company claims that the screen can be stretched more than 10 times without compromising image quality, even in extreme weather conditions. In addition to being light, thin and strong, the stretchable display can stick to surfaces with irregular curves, such as skin or clothing.
LG Display is leading the way in this technology as part of a nationwide study led by South Korea's Ministry of Trade, Industry and Energy. The goal of the project is to invent the next generation of display technologies. LG's successful development of stretchable displays has not only increased the flexibility of screens, but also helped South Korea achieve its larger goal of taking a leading position in the global display market.
"The latest panel can stretch up to 1,25 times its original size and has a resolution of 120 pixels per inch, which is comparable to gaming monitors," claims the display manufacturer.
Samsung claims that the flexible micro-LED display can be stretched up to 1,25 times, or "twisted like rubber", after which it will return to its original shape.
