Foldable smartphones are the real novelty of the market in recent years: they are the only ones to have grown in terms of shipments in recent months, and they are also the ones that have diversified the offer, now flattened by devices that are basically all the same that are now distinguished only by the shape of the rear photographic module. Among the protagonists of the foldable segment is Motorola, which with the renewed Moto Razr series has merged present and past with a fair amount of success. Not to mention the concepts and patents that demonstrate the commitment and willingness to bring products with an unprecedented form factor to the market.
So here is Moto Rollable, capable of unrolling from 5 to 6.5 inches, and again the smartphone-smartwatch shown by Lenovo at Tech World ’23 that with its folding screen wraps around the wrist. Among the patents there is a very special one that was approved just this week by the USPTO.
“Foldable communication device with two rollable displays”: this is the title of Motorola’s documentation. Essentially, both halves of the foldable smartphone’s display can separately stretch both vertically and horizontally, thus extending the usable surface area of the screen.
The smartphone has a controller that monitors the location of the device and uses the built-in sensors to detect when it is open. Once activated, the mechanism extends both flexible panels while magnifying the display up to four times.
On paper, the idea is intriguing, as we could have an extremely compact smartphone in our pocket that, when needed, can be enlarged. In addition, the user has the option to choose the direction in which the display is extended – i.e. portrait only, landscape only, or both.
However, several doubts remain, from the aesthetics to the functionality of the smartphone. It is obviously a patent and not a concrete product, what is certain is that Lenovo and Motorola are demonstrating with their concepts and the increasing number of patents that they believe in this segment.
