A new teardown of the LG Rollable has revealed how one of the smartphone industry’s most unusual cancelled devices was actually built, offering a rare close-up look at the mechanics behind its expanding display.
LG had already shown a willingness to experiment with bold form factors before it exited the phone business, including the LG Wing. But the rollable phone project went even further. The device reportedly made it close to mass production before LG shut down its mobile division, and only a limited batch was distributed internally to company employees.
That limited release is exactly why a full teardown has been so hard to find. The newly shared video from JerryRigEverything finally opens the phone up and shows how the flexible OLED panel extends and retracts from the body, rather than folding around a hinge like a conventional foldable.
Inside, the design uses a dual-motor system along with a spring-loaded mechanism built around three support structures. That arrangement helps the phone manage the movement of the display while keeping the internal electronics stable during expansion and retraction.
When the screen is rolled in, the curled portion of the OLED panel sits behind a transparent glass section that can act as a secondary display or a viewfinder for selfies with the main camera. It’s a clever reminder of how much engineering work went into the LG Rollable, even though the phone never reached a normal commercial launch.
