Compassion the poor foldable phone. In one case it was the future of mobile design — a way to transform a pocket-sized smartphone into a tablet-like device that you could yet bear around easily. With phone makers throwing their weight behind foldables, it didn't seem long before we'd take truly portable workstations that would allow usa to get things done on the go.

And and so, with simply a brief teaser at CES 2021 this calendar week, the rollable phone came along to knock its foldable counterpart off that lofty perch.

The rollable in question is the straightforwardly named LG Rollable, and all we know most it is that the screen can expand and shrink depending on whether you desire an expansive brandish or a portable device. We also know directly from LG that the phone is coming out this year. What nosotros don't know is everything else — how the rollable function works, what kinds of cameras the phone includes and merely how much information technology'south going to toll. (Our prediction? A lot.)

Still, that'southward non stopping the LG Rollable from condign i of the more talked-about unveilings at CES this year. We even gave the LG Rollable a Tom's Guide CES 2021 award. And that buzz is certainly understandable, according to Avi Greengart, lead analyst for Techsponential.

"Since rollable phones don't be yet, people are excited about the possibilities without thinking about probable downsides," Greengart said.

Those downsides certainly loom big. Merely so do the possibilities of rollable phones.

Rollable phones: The opportunities

Rollable [phones] will provide potential for innovation on the form factor equally well as potential applications given the new potential configurations.

— Tuoung Nguyen, Gartner

Tuong Nguyen, a senior principal analyst with Gartner, sees 2 appealing things well-nigh rollable screens — form factor and durability.

"Form gene is an interesting one because the smartphone industry has been focused on the slate for more than 13 years," Nguyen said. "Rollable [phones] will provide potential for innovation on the form gene too as potential applications given the new potential configurations."

Don't overlook the entreatment of immovability, though. To Nguyen, a rollable screen promises greater durability than a flat 1, since all of the screen won't ever be exposed. "I call back anyone who has had to live with a cracked screen for months or years tin can appreciate this benefit," Nguyen says.

It'south not merely about those factors, though. There's also the prospect of giving smartphone users more screen to piece of work with, while keeping the size of the overall device meaty plenty to tote around.

Foldable phones were supposed to provide that, too, and to some extent devices like the Milky way Z Fold two have. Just there are some trade-offs.

"[Foldable displays] accept creases and are twice every bit thick as a basic bar phone," said Greengart, noting the visible lines across fifty-fifty well-regarded foldables similar the Z Fold ii and the Galaxy Z Flip. A screen that doesn't need to bend, simply rather ringlet into place is unlikely to have those.

Rollable phones: The challenges

Nevertheless, there remain plenty of blanks for LG to fill up in if its rollable phone is going to convert the positive fizz from a CES teaser into a successful production launch. For instance, the phone maker is going to have to tell us more about that display and just how many times it can roll and unroll without any wear and tear.

That last signal is non an inconsiderable ane. An early stumbling block for foldable phones involved the phone's hinges — crucial for making the screen fold in ii, only vulnerable to other bug. The original Milky way Fold, for example, left a pocket-sized gap that could let grit and other particles through that could damage the screen. Samsung fixed the problem, but only after delaying the launch of that phone. With the moving parts that a rollable screen entails, we'll need to see how LG and others can ensure the devices keep working.

Greengart'southward looking for answers on immovability and screen size. But he besides wants to know about any trade-offs LG has had to brand in order to produce such a flexible screen. In other words, are there any trade-offs in brightness, HDR, color and screen refresh rate that a more conventional telephone wouldn't have to brand.

So at that place'southward the question of apps, and whether they'll take to be retrofitted to work with a new form factor. In the case of foldable phones, app makers had to tweak their software so that information technology could have reward of features like multitasking and the Flex model Samsung has introduced with its latest foldable devices.

That gets to the ultimate challenge facing the LG Rollable and whatsoever other rollable phones in development — convincing people that this detail pattern lets them use the phone in new and valuable ways. It just so happens that'south the challenge that foldable phones still fence with, also.

"Both class factors are being discovered in the sense that the use cases haven't been defined, yet," Nguyen said. "From a consumer perspective, this means 'how does this amend my life?'"

Rollable phones: What happens next

Don't expect foldable phones to leave the stage gracefully now that the LG Rollable is imminent. Samsung reportedly has new versions of the Galaxy Z Fold and Flip in the works for this year, and according to Samsung Electronics president TM Roh, the company's eager to come out with additional designs, some of which are expected to exist more affordable than the current models.

As for the LG Rollable, at that place'southward a big divergence betwixt CES keynote darling and shipping production. Await for more than details to emerge about this rollable telephone — and hopefully more answers virtually just how it volition piece of work.
