The LG Wing, with its rotating dual display system, is one of the most interesting smartphones of 2020. And thanks to the demolition of the device by YouTuber JerryRigEverything, we now know how LG managed to make this pivoting screen a reality.
It's actually pretty wild: a hole is cut through the printed circuit board (PCB) and main frame of the phone, through which a flexible ribbon cable is run to allow the main rotating display to both function and rotate. There's also a tiny hydraulic damper that doubles as a shock absorbing cushion when you open the phone.

The actual hinge mechanism consists of a pair of riveted plates held together by two springs: one to keep the phone open and one to keep it closed. There are also two sliding rails which, according to JerryRigEverything, work almost like a door chain lock to keep everything in place when the phone is opened and closed.
The other noteworthy piece of information is that while the Wing doesn't have an IP rating for water resistance (not surprising given the moving parts), LG appears to have coated the internal circuit boards with a water-repellent coating – so hopefully it won. & # 39; Don't die immediately if it runs into the water.
