Displays that can be folded and rolled up have been shown in prototype smartphones, wearables and other devices -- but when will such products be available?
Advances in technology suggest they aren't too far off in the future. Such devices could start showing up as early as next year or 2018, said Jerry Kang, senior principal analyst for emerging display technologies and OLED at analyst firm IHS.
Manufacturers are trying to launch them in devices like tablets that can fold into a smartphone-size device. It's possible to use these displays in wearable devices, but reliability, weight and battery life need to be considered, Kang said.
Small folding screens will likely come before larger ones, mainly due to the economics of making such displays, Kang said.
