This month LG showed off a prototype of their stretchable display, which can be expanded up to 50%, stretching from 12" to 18". The micro-LED display has a 100ppI resolution and displays RGB.

The company was able to achieve the feat by using silicon substrate and a proprietary wiring structure. It presumably wasn't cheap to develop, but the company didn't do it alone: With the backing of South Korea's Ministry of Trade, Industry and Energy (MOTIE) and the Korea Planning & Evaluation Institute of Industrial Technology, LG did joint R&D on the project with 19 different domestic industry and research institutes.

So what's the actual application? "Stretchable displays are not only thin and lightweight but also capable of adhering to irregularly curved surfaces like clothing and skin," the company writes. "They are expected to be widely applied in various industries, from fashion and wearables to mobility." Additionally, they released a press image of the screen having been stretched over a contoured automotive interior panel, below, and they mention (but don't show) that it could be integrated with firefighters' uniforms to provide communications.
