LG Display introduced the first expandable display that can be expanded by 50%, marking the highest height standard in the display industry. The prototype, presented on November 8 at LG Science Park in Seoul, it has a 12-inch screen that expands up to 18 inches while maintaining a high resolution of 100 pixels per inch and vivid RGB color. The exhibition involved more than 100 representatives from South Korea’s industry, academia, and research sectors who participated in a national light demonstration project.
Flexible displays are very important because of their flexibility, which allows them to bend, fold, and twist freely, adapting to an unfamiliar environment such as clothing and skin. LG Display’s new panel, which doubles the scale of the first prototype launched in 2022, holds promise for wearable applications in technology, fashion, and automotive communications. Enhanced elasticity and durability allows the display to withstand more than 10,000 stretches while maintaining image clarity, even in extreme conditions.
The breakthrough comes from improved materials and design improvements, including a special silicon substrate inspired by contact lenses and a new cable structure. Additionally, a micro-LED light source measuring 40 micrometers ensures durability and flexibility. This innovation is in line with LG Display’s commitment to developing next-generation display technology in collaboration with South Korea’s Ministry of Trade, Industry, and Energy (MOTIE).
As a project leader since 2020, LG Display has collaborated with 19 local industries and research organizations. By developing this technology, LG Display aims to promote a sustainable display ecosystem and establish an R&D infrastructure that supports material and component localization. CTO Soo-young Yoon emphasized the company’s commitment to building strong partnerships across South Korea’s display industry, opening a competitive path for scalable display applications in various industries.
Flexible displays are not new; it’s been a while since we’ve seen themincluding smart watches, smartphones, and TVs. Over the past decade, major brands have launched devices with curved displays, such as the 2014 Samsung Gear S smartwatch, the 2013 LG Flex smartphone, and the first curved 3D OLED TV launched by LG in CES 2013.
By 2021, curved TVs are almost extinct, but curved smartwatches saw a revival in 2019 and 2020, with the Nubia Alpha and Amazfit X. Curved smartphones were replaced in 2018 and 2019 by foldable smartphones, and curved displays found practical applications such as gamekeepers.
LG is always looking for applications in the mass market for flexible and flexible displays. With new groundbreaking like the world’s first rolling OLED TV in 2019 as well as The first 42-inch bendable OLED TV in 2022LG probably inspired other brands like Lenovo, Motorola, and Samsung (although Samsung has experimented with rollable displays before). These OEMs showcased rollable and bendable displays for laptops, smartphones, and wrist-worn devices at international trade shows in 2023 and 2024.
With this latest innovation, LG is pushing the envelopeand we expect to see impressive applications of this new technology soon.
