LG's Rubbery New Display Can Be Twisted, Folded and Stretched Up to 20%
LG Display has ambitious plans for the future of display technology and how it can be used. The latest product from the division is a stretchy full-color RGB display that can be twisted and folded without distorting its 100ppi resolution.
Engineered from a film-type substrate made of silicon, the same material used in contact lenses, the 12-inch (305 mm) display can not only be crumpled and contorted but can literally be stretched. Its rubbery flexibility allows the display to extend to 14 inches (356 mm), a 20% increase in size.
The display is layered with micro-LED lights smaller than 40 micrometers. The low density of pixel pitch lends itself to high resolution in tandem with a high level of durability. LG says that the quality of its stretchable display competes with that of most existing monitors today. Instead of linear wiring, the display employs an S-form spring system, which allows it to undergo repetitive changes without permanently losing shape and rubber band-like quality.
Developers envision that the display can be used across a variety of applications, from wrapping cars to being used as a textile to make clothing and furniture.
