LG has unveiled a new prototype strechable display capable of expanding up to 50%, increasing from a 12-inch screen to an 18-inch screen. This transformative display can adapt to various shapes. Showcased in 2022, a previous prototype offered only a 20% expansion rate; the new prototype boasts significantly enhanced flexibility and a 50% expansion rate.

This prototype, unveiled at LG Science Park in Seoul, represents a substantial advancement over previous models, showcasing potential across numerous applications.

LG Strechable Display Key Features

• Unprecedented Stretchability: The new LG stretchable display expands from 12 inches to 18 inches—a 50% increase. This surpasses LG’s 2022 prototype (20% expansion) and outperforms Samsung’s latest stretchable display (25% expansion).
• Durability and Resilience: Constructed with a resilient film-type substrate of specialized silicon (similar to contact lenses), the display offers rubber-band-like flexibility. It can stretch repeatedly over 10,000 times without compromising clarity or image quality.
• High Resolution and Color Fidelity: Despite its stretchability, the display maintains a sharp 100 ppi resolution and vibrant RGB color, ensuring a clear and visually appealing image even when stretched.
• Micro-LED Light Source: Utilizing a micro-LED light source (up to 40 micrometers), the display is durable and can withstand extreme temperatures and impacts.

Potential Applications and Implications

The display’s enhanced stretchability offers vast application potential across various sectors:

• Fashion and Wearables: Its ability to conform to irregular surfaces (clothing, skin) makes it ideal for wearable technology. Imagine clothing displaying real-time information, changing designs, or functioning as a touchscreen.
• Mobility: The display’s flexibility could revolutionize automotive design, enabling curved car panels with interactive dashboards and information displays.
• Firefighting and Emergency Response: Wearable displays on firefighters’ uniforms could provide real-time data and situational awareness, improving safety and efficiency.
• Consumer Electronics: This technology could lead to foldable smartphones and tablets that expand for larger screens, enhancing versatility and user experience.

Development and Future Prospects

LG Display has been developing stretchable display technology since 2020, participating in a South Korean government initiative to advance the nation’s next-generation display industry. The company has collaborated with numerous organizations within the country’s industrial-academic sector to develop this innovative prototype.

While still in its early stages, this stretchable display is a significant milestone. LG’s commitment to R&D, combined with the technology’s potential applications, suggests stretchable displays could become a major force in the display industry.
