As often as companies love to toy with flexible displays, we're seldom told how we'd control that newfound freedom. Are we supposed to make e-paper cranes? Credit LG for some forward thinking -- it's just receiving a US patent for a 2008-era user interface invention that would use a bending screen to its advantage. The implementation includes two displays, one of which flexes while the other accepts touch; bend or fold the first display, and the touchscreen changes to suit the context. Having two closely linked displays would also let the panels run either in unity or independently. Suffice it to say that the technology is unlikely to roll out as-is on a smartphone, if ever: LG's attention has swung towards having one big touchscreen as of late. However, the interface does give the Korean firm a place to start if it develops devices to match its new flexible batteries.
