Samsung's upcoming flagship smartphone, unofficially dubbed the Galaxy X, is expected to incorporate a whopping three LED panels, reports The Bell (via Forbes).

When fully unfolded, two of the 3.5-inch LED panels would combine to create a massive seven-inch display — almost as large as that of the iPad Mini.

The third panel, which you use when it's in "phone mode," would be on the back of the device when it's in "tablet mode." Basically, think of this hybrid device as a book with a screen on the front, and two screens on the inside.

If true, this leak would be in line with other rumors we've heard this year. Samsung has been eyeing foldable displays since as far back as 2011, when it released a concept video of a transparent, foldable tablet. A Samsung executive noted at this year's Mobile World Congress that the company aims to market the first high-end foldable smartphone. It was rumored that we'd see the folding Galaxy X in 2017, but that, of course, didn't pan out.

Samsung also isn't the only company in the race to build a foldable phone.

In 2017, Apple received a patent for an electronic device with a "flexible display." It's much less clear what this phone would look like — for all we know, it could be shaped like a fruit roll-up. ZTE also released a foldable phone last October, but there's a huge bezel between the two screens, so we were underwhelmed.
