LG’s Wing — with its rotating dual-display system — is one of 2020’s most interesting-looking smartphones. And thanks to YouTuber JerryRigEverything’s teardown of the device, we now know just how LG managed to make that swiveling screen a reality.
It’s actually pretty wild: there’s a hole cut through the printed circle board (PCB) and the main frame of the phone, which has a flexible ribbon cable threaded through it to allow the rotating main display to both function and twist around. There’s also a tiny hydraulic damper to serve as a shock-absorbing cushion for when you flip the phone open.
