LG Display, a subsidiary of the South Korea-based conglomerate focused on display technology, has unveiled a new stretchable display that can expand up to 50 percent of its original size. The company introduced the new stretchable display panel during a meeting of more than 100 South Korean industry, academics and research stakeholders at LG Science Park in Seoul last week. The tech giant showcased a 12-inch panel that can be expanded to 18 inches, delivering high-resolution and sharp image quality.

In a newsroom post, LG Display explained this new technology in detail. The company claimed that the 50 percent elongation rate it achieved was “the highest elongation rate in the industry”. The stretchable panel demonstrated during the meeting was a 12-inch screen that expanded to 18 inches. The company claimed that at its full extension, the panel still offers 100 pixels per inch (ppi) resolution and the full red-blue-green (RBG) color spectrum.
LG claimed that the new display prototype is better than the first stretchable display shown in 2022, which can be expanded up to 20 percent of its original size. The company claimed to have “improved the properties of a special silicone material substrate used in contact lenses” and developed a new wiring design structure to achieve new elongation rates.
The company also claimed that the new prototype improves its durability by using a MicroLED light source of up to 40 micrometers. With this, LG Display said that the stretchable display can be stretched more than 10,000 times and maintain high-resolution image quality during extreme exposures, high ranges of temperatures as well as external shocks.
Specifically, stretchable displays are free-form screen technology that can be transformed into any shape by stretching, bending, and twisting. Being thin and lightweight, they can be used on irregular and curved surfaces such as clothing and skin. The company highlighted that the technology is expected to be used in industries such as fashion, wearables, and mobility.
During the meeting, LG Display also demonstrated several applications of the prototype. The company unveiled an automotive panel that stretches into a convex shape with touch support and a wearable display attached to firefighters’ uniforms that can provide real-time information.
