Stretchable displays appear to be the ultimate free-form display technology because they can be freely transformed into any shape, including by stretching, folding, and rotating.
The new prototype has a 12-inch screen that stretches to 18 inchesswhile simultaneously delivering a high resolution of 100ppi (pixels per inch) and full red, green, and blue (RGB) colors.
Compared to the first Stretchable display prototype announced in 2022, the maximum elongation rate of the new panel has doubled from 20% to 50%. This enhanced stretchability allows for a wide range of display design possibilities, increasing the technology’s potential competitiveness when commercialized.
By applying several new technologies, such as improving the properties of the special silicon material substrate used in contact lenses and developing a new cable design structure, LG Display Kab increase the stretchability and flexibility of the panel, exceeding the original national project target of 20% elongation.
In addition, by using a micro-LED light source up to 40μm (micrometers), the durability of the new prototype means that it can be repeatedly stretched more than 10,000 times, maintaining clear image quality even in extreme environments such as exposure to low or high temperatures . and external shocks.
The stretchable display is not only thin and light but can also stick to irregular curved surfaces like clothes and skin. It is expected to be widely used in various industries, from fashion and wearables to mobility.
The company presented several concepts for Stretchable display applications, including an automotive panel that stretches into a convex shape and can be operated by hand as well as a wearable display attached to firefighter uniforms that provides real-time information.
LG Display Kab was chosen as the main company for the national project to develop Stretchable display in 2020 and since then has been conducting joint R&D with 19 domestic industries and research institutes. This is one of the main tasks of the wider project to develop the core technology for the next generation display presented by
By successfully completing the project, LG Display Kab not only securing the core technology that can lead the next-generation display market but also contributing to the localization of materials, components, and equipment as well as building the R&D infrastructure.
“We will continue to build a sustainable future display ecosystem through close cooperation between South Korean industry, academia, and research stakeholders,” he said.
