This canceled LG Rollable phone makes today’s designs look dated

This canceled LG Rollable smartphone highlights how far behind today’s designs feel. A newly surfaced teardown from JerryRigEverything shows the device wasn’t just experimental, it pushed further than what you can actually buy today.

The LG Rollable smartphone never reached store shelves, but it did make it into the hands of a few internal users. Now, a teardown video details how much engineering went into a phone that almost launched back in 2021.

What stands out is how complete the concept feels. Even after five years, the hardware works, and the approach tackles problems foldables continue to face.

A closer look at the internals highlights a level of engineering that remains rare. Instead of a hinge, the LG Rollable smartphone relies on a motorized system to expand and retract its display, something no mainstream phone offers yet, unless Samsung quickly releases one.

At the core are two motors working with a spring-loaded structure made up of three arms. This setup keeps internal components aligned as the screen moves, reducing the uneven stress seen in folding designs.

There’s also a secondary use when the phone is closed. Part of the flexible OLED rolls behind a transparent panel and becomes a rear display, letting you preview selfies with the main camera.

What defines the LG Rollable smartphone isn’t just the mechanism, it’s how cohesive the idea is compared to what followed. Foldables today focus on bending screens, but they continue to deal with visible creases, thicker builds, and durability concerns.

LG’s approach avoids some of those issues. By rolling the display instead of folding it, the design removes a hard crease entirely. The expansion also gives more flexibility, without locking the screen into a fixed fold point.

A closer look confirms this wasn’t a rough prototype. It was near ready. But it never faced mass production, which leaves long-term durability at scale untested.

The LG Rollable smartphone shows how quickly promising ideas can disappear. LG exited the phone business before it could bring this phone to market, leaving one of the most ambitious concepts behind.

What’s striking is how little of this approach has carried forward. Other manufacturers refined foldables, but none pushed a rollable design into the mainstream in the same way. The gap between what was possible and what shipped remains clear.

For now, the LG Rollable stands as a glimpse of an alternate path. If rollable designs return, the groundwork is already there.
