The LG Rollable, a prototype smartphone that aimed to revolutionize the market with its unique rollable screen, has been dissected in a recent teardown by YouTube tech reviewer JerryRigEverything. Initially teased in 2021, the device was designed to expand its screen area by approximately 40 percent without increasing thickness, a significant advantage over traditional foldable phones like the Samsung Galaxy Z Fold. However, the internal mechanics of the LG Rollable are complex, featuring two motors that operate a rolling mechanism and spring-loaded arms to maintain the OLED panel's integrity. Despite its innovative design, the high production costs and the intricate technology involved made rollable phones less feasible for mass production. Ultimately, LG's exit from the smartphone market in 2021 underscored the challenges of competing in an industry dominated by established players. The teardown not only preserved this piece of mobile history but also provided valuable insights into the ambitious yet ultimately unviable concept of rollable smartphones.
