The world’s first stretchable screen can now get even bigger: The technology behind the innovation explained

It’s 2024 and we’ve seen a range of innovative displays, from rollable and bendable displays to transparent displays. Currently, LG in South Korea has unveiled a new stretchable display panel that can expand by 50%. But why is it called “stretchable”? LG claim that this display can expand up to 50 percent, currently the highest elongation ratio in the industry. This means you can shape the screen by folding, twisting, or stretching it.

The possibilities are huge. Think of a future where these stretchable displays are integrated into curved surfaces, such as in wearable straps, or even integrated into clothing that adapts to the shape of your body. In automotive applications, stretchable displays could revolutionize car dashboards. Sounds like something out of a science fiction movie, right?

The technology behind LG’s stretchable display: Explained

The prototype launched at LG Science Park in Seoul has a 12-inch display panel, but what’s unique is that it can stretch up to 18 inches with a screen that offers 100 PPI (pixels per inch) and full RGB color spectrum. enough.

LG says achieving this level of flexibility is the use of special silicon material in the display. The material is similar to that found in contact lenses, and with it, LG has developed a new wire design structure, ensuring the screen remains functional even when stretched.

In addition, LG also uses microphones LEAD TO Lighting technology in a stretchable screen, measuring only 40 micrometers. This is said to increase the durability of the display, making it resistant to wear and tear, even after being stretched more than 10,000 times. Additionally, thanks to this, the display can withstand both low and high temperatures as well as be resistant to external shocks,

Although stretchable displays may seem like a new concept, LG has been working on it for several years. The company first introduced the stretchable display concept in 2022, but in just two years, LG has more than doubled the stretch rate, increasing from 20% to 50%.

Performances at LG Science Park and What Does the Future Look Like?

At the LG Science Park event, the company introduced many potential applications for stretchable displays. One particularly interesting demonstration involved a car dashboard with a stretchable convex screen. Imagine such displays eventually replacing the current car dashboards we are familiar with, providing a more dynamic and interactive user experience.

For example, imagine big brands like Nike integrating stretchable screens into their products. Imagine a pair of Nike Dunk Low sneakers with stretchable screens—it’s an idea straight out of a sci-fi movie, and LG appears to be one of the first companies to pave the way for this revolution. .
