Hot rumor has Sony prepping a foldable phone with a retractable rolling display
11

After the Royale FlexPai was unveiled last October, it was expected that the big boys would start dominating the foldable phone category. But days before it was to launch the Galaxy Fold, Samsung delayed the release due to a number of issues with the $1,980 device. And depending on your definition of summer, Huawei has also delayed the release of its foldable Mate X by three months. Samsung has apparently made the necssary repairs to the Galaxy Fold, but we can understand why it is not rushing it out right now. Samsung Electronics chief D.J. Koh admitted last week that Sammy had rushed to get its foldable out the first time, and it doesn't want to repeat the same mistake twice.
Sony's foldable will apparently have a retractable roll-out display
Unlike the Galaxy Fold or Mate X, the tweet notes that Sony's foldable will use a Nautilus design. This means that it could use the retractable roll-out form factor similar to what Samsung included in illustrations for a patent it recently received. And back in 2016, Samsung also put a prototype rollable OLED screen on display. The patent mentioned using rails to help a user expand a smartphone display by pulling on both sides of the device. This would turn a smartphone into a tablet. Assuming that there are no setbacks, the tipster notes that Sony's foldable could launch in late December 2019, or early next year.

Any type of retractable rollable phone would have to deal with debris and dust. As Samsung found out with the Galaxy Fold, all it takes is a little piece of foreign material to get sucked in through an opening and there could be problems. One influencer found a bulge on the internal screen of his Galaxy Fold review unit after debris was sucked into the device through an opening in the hinge. Samsung has reportedly reduced the size of that gap to prevent it from happening again.
To show that it is starting over from scratch, Sony named its flagship model this year the Xperia 1 and is using a more cinematic friendly 21:9 aspect ratio. That makes the screen thin and wide and those viewing streamed content in landscape mode will notice a superior viewing experience. The 6.5-inch AMOLED display carries a resolution of 1644 x 3840 pixels and provides a whopping 643 ppi pixel density.
Producing a foldable device now would seem strange for a company that is bleeding red ink from its mobile division, but this is a business that Sony really wants to succeed in. As a result, if this leak is legit, the company is pulling out all of the stops to make a mark in the industry.
