This discontinued LG Rollable phone makes current designs appear outdated.

      The canceled LG Rollable smartphone underscores just how outdated many current designs seem. A recent teardown by JerryRigEverything reveals that the device wasn't merely a prototype; it advanced beyond what's available for purchase today.

      Although the LG Rollable smartphone never made it to retail, it did reach a select group of internal users. A teardown video now elaborates on the extensive engineering involved in a phone that was nearly released in 2021.

      What is particularly notable is the completeness of the concept. Even after five years, the hardware functions well, and the design addresses challenges that foldable phones still encounter.

      Examining the rollable mechanism in detail reveals a level of engineering that is still uncommon. Instead of using a hinge, the LG Rollable smartphone employs a motorized system to extend and retract its display, which is something that no mainstream phone currently offers, unless Samsung rapidly introduces one.

      At its core are two motors that work in conjunction with a spring-loaded structure made of three arms. This arrangement maintains alignment among the internal components as the screen moves, minimizing the uneven stress typically seen in foldable designs.

      Additionally, when the phone is closed, part of the flexible OLED display rolls behind a transparent panel and functions as a rear display, allowing users to preview selfies with the main camera.

      The LG Rollable smartphone's significance lies not only in its mechanism but also in the coherence of its concept compared to subsequent designs. While current foldables concentrate on bending screens, they still struggle with visible creases, bulkier designs, and issues of durability.

      LG’s method circumvents some of these problems. By rolling the display rather than folding it, the design eliminates any hard crease. The expansion feature also offers greater flexibility without confining the screen to a specific fold point.

      A detailed examination confirms that this device wasn't just a rough prototype; it was nearly production-ready. However, it never entered mass production, leaving its long-term durability untested in real-world scenarios.

      The LG Rollable smartphone illustrates how swiftly promising innovations can fade away. LG exited the mobile market before it could launch this device, leaving behind an ambitious concept.

      What stands out is how little of this innovation has been adopted by others. While different manufacturers have fine-tuned foldable designs, none have successfully introduced a rollable format to the mainstream in the same way. The disparity between achievable technology and what has been brought to market remains evident.

      For now, the LG Rollable serves as a hint of an alternative future. Should rollable designs make a comeback, the foundation for them is already established.
