Lenovo's Rollable Laptop and Smartphone Are a Compelling, Unfinished Pitch For the Future

mardi 28 février 2023, 02:30 , par Slashdot
At Mobile World Congress in Barcelona, Lenovo demoed a laptop and smartphone with rollable screens that 'can gradually expand to offer more screen real-estate, rather than needing to be completely unfolded like books,' writes Jon Porter from The Verge. These are early proof of concept devices that don't have any public release dates as of yet. From the report: Before we get into the concept laptop's signature feature, it's worth pointing out just how unassuming the device looks before its screen unrolls. Lenovo had the device sitting alongside its other laptops in a conference suite, and not a single one of the dozen-or-so journalists in attendance clocked that it was anything other than a standard ThinkPad. In its unextended form, it's got a regular looking 12.7-inch display with a 4:3 aspect ratio. That all changes with a flip of a small switch on the right of the chassis, at which point you can hear some motors whirring and the screen extends upwards. That switch causes a couple of motors in the laptop to spring into action, pulling the screen out from underneath the laptop's keyboard to hoist it up more or less vertically in front of you. It's an admittedly slow process on this concept device (from our footage it seems to take a little over ten seconds to fully extend) but eventually you're left with an almost square 15.3-inch display with an 8:9 aspect ratio. The device brings to mind LG's fancy (and eye-wateringly expensive) rollable TV that's designed to roll away when you're not using it. Only in Lenovo's case the screen is rolling down into the laptop's keyboard rather than a small box, and it also can't roll away entirely. Once fully extended, Lenovo's laptop screen has a small crease where its screen originally bent underneath the keyboard. But again -- it's a prototype.

Lenovo's other rollable device it's demoing at MWC is a Motorola smartphone. We've seen numerous companies including Samsung Display, Oppo, TCL, and even LG (RIP) show off rollable concept devices in various stages of development over the years, but we're yet to see the technology break through in a consumer device. Like a foldable, the idea is that a rollable smartphone can be small when you need it to be portable, and big when you need more screen to get the job at hand done. Lenovo's phone -- which it's calling the Motorola rollable smartphone concept -- is all about taking a small square of a display and making it longer. It's almost like a foldable flip phone, but without a secondary cover display because it's the same screen the entire time. When all neatly rolled up, Lenovo's Motorola rollable offers a 5-inch display with a 15:9 aspect ratio. Then, with a small double tap of a side button, the screen unfurls to give you a remarkably tall 6.5-inch display with a 22:9 aspect ratio. 'In 2019, it seemed like foldable phones were about to become the next big thing in the world of smartphones,' writes Porter, in closing. 'But four years later, it feels like we're still waiting for this future to become a mainstream reality. Lenovo would be the first to admit that its rollable concept devices are far from ready for prime time, but they offer a compelling argument for an alternative, rollable future.'
