The LG Rollable smartphone, which was on the verge of mass production before LG's mobile division was shut down, showcases a groundbreaking rollable display design. In a recent teardown video by JerryRigEverything, viewers can see the internal workings of this innovative device, which features a flexible OLED display that rolls out and retracts. The mechanism is powered by two motors and a spring system with three arms, allowing for smooth movement of the internal components. When retracted, the display hides behind a transparent glass panel, functioning as a secondary display for notifications and selfie previews. This device, produced in limited numbers for LG employees, remains a testament to LG's commitment to innovation in smartphone design, especially given that it has remained functional for five years. The video provides a rare glimpse into the engineering behind the LG Rollable, which was one of the last ambitious projects from the company.
