LG Rollable Disassembly Reveals That the Unreleased Phone Is an Engineering Masterpiece.
The consumer electronics field seems poised for major breakthroughs, but it's also littered with devices that never quite made it across the finish line. Thanks to YouTuber JerryRigEverything, the world can now get a close-up look at one such device: LG's unreleased rollable phone. LG's mobile division shut down before this innovative device could be released, which was scheduled for sometime in 2021.
Five years later, the design of the LG Rollable still feels futuristic. The display expands or contracts with a simple swipe gesture, transforming from a 5.5-inch screen to a 7.5-inch screen. LG also ensured that the Android operating system functioned smoothly during these transitions, and the process was remarkably seamless despite the software being unreleased.
As is typical of JerryRigEverything's videos, a teardown of the phone was conducted to examine LG's impressive engineering feat in detail. The rolling mechanism is powered by dual gear motors and a set of three spring-loaded arms. This system proved to be incredibly strong, capable of pushing out two thick textbooks as the display extended.
The LG engineering team clearly anticipated potential problems caused by dust. After all, once dust gets inside the back of the device, it's not easy for users to clean. To mitigate this, the company added a series of bristles along the edge of the rear glass to prevent dust and debris from seeping in.
It's truly unfortunate that LG never released this product and has since completely withdrawn from the phone business. LG clearly had talented teams with remarkable abilities, and it's a shame they are no longer active. It would have been fascinating to see what joy they could have brought to phone enthusiasts. Moreover, it would have been interesting to see this rollable concept go head-to-head with the foldable designs we see today.
Fortunately, JerryRigEverything was able to perfectly reassemble the device, ensuring that this marvel of engineering is preserved.
