The smartphone industry has been continuously pushing boundaries to fit larger screens into smaller bodies. Foldable devices have been the big trend over the past few years, but LG toyed with a concept that might have changed everything: a rollable phone. Though never released, this prototype marked one of LG's most cutting-edge developments before the company exited the smartphone business. Here’s why this device was so remarkable—and why it never made it to stores.

A Bold Concept: What Made the Rollable Phone Unique?

The LG rollable phone aimed to solve the challenges posed by current foldable phones, like Samsung’s Galaxy Z Fold series. Folding devices may be innovative, but they come with inherent flaws such as noticeable creases on the screen and bulky designs when folded. LG’s solution embraced something entirely different: what if, instead of folding, the screen could unroll? Using a flexible OLED panel, the rollable phone featured a screen that could expand seamlessly from a compact candy bar width to a tablet-like 7.4 inches. While this was slightly smaller than the 8-inch unfolded screen of a contemporary Galaxy Z Fold model, LG’s design excelled in screen usability thanks to its 3:2 aspect ratio, which provided more practical screen space.
Even more fascinating, the innovation didn’t stop with the screen’s expandable feature. When rolled into its more compact form, the screen’s backside remained partially accessible. This allowed functionality like taking selfies with the rear camera using the rolled-back screen as a live viewfinder—a feature that merged unique practicality with flair.

Why Didn’t It Launch?

Despite its promise, LG’s rollable phone was plagued by technical and durability concerns that simply couldn’t be ignored. Key among these issues was the screen’s vulnerability. The flexible OLED display was described as so soft that it could be scratched with something as minor as a fingernail. This posed a significant durability problem, especially considering that the screen rolled around the phone’s exterior, remaining completely exposed when not in its compact configuration. Unlike foldables, which typically tuck their displays inside for protection when closed, LG’s rollable left its screen open to potential damage. This design choice meant it wouldn’t survive the rigors of daily use, especially when placed in a pocket or bag.
Durability is a key factor for any smartphone, and in this case, LG’s innovative design came at the price of practicality. Given the significant trade-offs and the likely high manufacturing costs, the rollable phone may have represented too great a risk for LG, especially as they were already struggling to maintain profitability in their smartphone division.

The End of an Era for LG Smartphones

The rollable phone’s story reflects both the brilliance and tragedy of LG’s smartphone division. Known for its willingness to take risks, LG was often a trailblazer with concepts that pushed the industry forward. From including ultra-wide cameras in phones before anyone else to experimenting with modular designs, LG consistently favored innovation over following trends. This willingness to experiment endeared the brand to its fans, but it also came with challenges. While LG often led the way with unique ideas, these concepts were sometimes underdeveloped, saddling the company with products that struggled to gain market traction.
By 2021, LG made the decision to exit the smartphone market altogether, shifting its resources to other areas of its electronics business. For LG enthusiasts, the rollable phone joined the list of imaginative “what-ifs” that could have redefined the market but ultimately faced technical or commercial hurdles too great to overcome.

How LG’s Rollable Compared to Foldables

At its core, LG’s rollable phone sought to address the key complaints about folding devices. Its lack of a fold meant no visible crease, offering a more seamless and elegant appearance. When collapsed, it maintained the slim and sleek profile of a traditional smartphone, avoiding the bulk associated with foldables like Samsung’s Galaxy Z Fold or Z Flip lines. Furthermore, the rollable concept eliminated durability concerns associated with repeated folding and unfolding.
Yet these advantages were undermined by the glaring vulnerability of its exposed design. Foldables, for all their flaws, protect the internal display when closed. LG’s rollable design sacrificed that protection for a sleeker, more novel form factor, and the trade-off proved too significant to ignore.

The Legacy of the LG Rollable

Although the LG rollable phone never reached consumers, its concept still holds lessons for the industry. As foldable and rollable technologies continue to evolve, manufacturers may yet find ways to address the durability challenges that LG could not overcome. The rise of ultra-thin glass and other flexible materials might pave the way for rollable phones to succeed where LG’s prototype fell short. LG’s commitment to exploring bold new ideas ensured the company left behind a legacy of ambitious designs. For fans, the rollable phone remains a bittersweet reminder of what could have been. It was a device that blended the best of candy bar and foldable designs while trying to eliminate their weaknesses. Despite its failure to launch, the rollable phone represents a fascinating chapter in smartphone design history.
The question persists, though: what if LG had been able to perfect the rollable concept? Would we now be seeing a market dominated by rollables instead of foldables? For now, we can only speculate, as LG’s departure from the smartphone world means it will be up to other manufacturers to revisit the rollable idea. Until then, LG’s rollable phone remains a tantalizing glimpse of a future that almost arrived.
