In a demo showed at the Global Tech Korea conference, Samsung showed off a 13-inch stretchable OLED display, according to Korean outlet, ET News. Unlike current generations of foldable displays, the stretchable tech can theoretically do more than just enable new form factors.
Demo aside, stretchable displays are still very much a work in progress. Samsung initially showcased the technology in 2017, and similar displays — ones with application in wearables — have also been the subject of more recent academic papers.
