Inside LG’s Rollable Prototype: Why Rollable Smartphones Never Reached the Market
A recent teardown of LG’s never-released Rollable smartphone reveals why rollable phones never became a mainstream reality. According to Ars Technica, the concept, though visually stunning and innovative, was simply too complex, fragile, and expensive for widespread production. The teardown, performed by YouTube creator JerryRigEverything, shows the intricate mechanics required to make the device function. The LG Rollable uses multiple miniature motors, a system of articulating spring-loaded arms, and a flexible OLED screen that wraps around the back when retracted. This allows the phone’s display to expand by about 40 percent with a smooth motorized motion. However, this engineering marvel comes at a high cost—literally and structurally. Each moving part introduces greater risk of mechanical failure, and the wrap-around OLED screen raises serious durability and longevity concerns. Reports note that LG even added an audio chime to mask the noise produced by the motors, highlighting how complicated and delicate the system was. Although LG’s design effectively demonstrated how far flexible screen technology had come, the teardown suggests that the Rollable’s complexity and cost would have made it impractical for consumers. LG, which showcased the phone at CES 2021 before exiting the smartphone market altogether, provides an interesting glimpse into a path not taken in mobile innovation.
