SEOUL, South Korea , Nov. 9, 2024 — LG Display, a leading innovator in display technologies, announced its development of the world’s first Stretchable display capable of expanding up to 50%. This represents the highest elongation rate achieved in the industry. The company showcased this groundbreaking panel at LG Science Park in Seoul on Nov. 8 to over 100 industry, academic, and research stakeholders involved in a national Stretchable display project.
Stretchable displays are considered the ultimate free-form screen technology due to their ability to transform into any shape through stretching, folding, and twisting.
The new prototype boasts a 12-inch screen that can stretch to 18 inches, while maintaining a high resolution of 100ppi (pixels per inch) and delivering full red, green, and blue (RGB) color.
Compared to the initial Stretchable display prototype unveiled in 2022, the new panel’s maximum elongation rate has more than doubled, increasing from 20% to 50%. This enhanced stretchability opens up a wider range of display design possibilities, bolstering the technology’s potential competitiveness once commercialized.
LG Display achieved this breakthrough by implementing several new technologies. This includes refining the properties of a special silicon material substrate used in contact lenses and developing a new wiring design structure. These advancements significantly improved the panel’s stretchability and flexibility, exceeding the original national project’s target of 20% elongation.
Furthermore, by utilizing a micro-LED light source of up to 40μm (micrometers), the new prototype’s robust durability allows for repeated stretching over 10,000 times while maintaining clear image quality even in extreme environments, such as exposure to low or high temperatures and external shocks.
Stretchable displays not only offer thinness and lightweight features but also the capability to adhere to irregularly curved surfaces like clothing and skin. This makes them highly promising for diverse industries, ranging from fashion and wearables to mobility.
LG Display demonstrated several concepts showcasing potential applications of Stretchable displays. This includes an automotive panel that extends into a convex shape for manual operation and a wearable display designed for firefighters’ uniforms to provide real-time information.
LG Display was chosen as the lead company for the national project to develop Stretchable displays in 2020 and has since collaborated with 19 domestic industry and research institutes on joint R&D. This project falls under a larger initiative focused on developing core technologies for next-generation displays, spearheaded by South Korea’s Ministry of Trade, Industry and Energy (MOTIE) alongside the Korea Planning & Evaluation Institute of Industrial Technology.
By successfully completing this project, LG Display has not only secured core technologies that will lead the next-generation display market but also contributed to localizing materials, components, and equipment, while building a robust R&D infrastructure.
“We are committed to creating a sustainable future display ecosystem through close collaboration between South Korean industry, academia, and research stakeholders,” stated Soo-young Yoon, CTO and Executive Vice President of LG Display.
