"From a consumer perspective, this means 'how does this improve my life?'" Rollable phones: What happens nextĭon't expect foldable phones to exit the stage gracefully now that the LG Rollable is imminent. "Both form factors are being discovered in the sense that the use cases haven’t been defined, yet," Nguyen said. It just so happens that's the challenge that foldable phones still contend with, too. That gets to the ultimate challenge facing the LG Rollable and any other rollable phones in development - convincing people that this particular design lets them use the phone in new and valuable ways. In the case of foldable phones, app makers had to tweak their software so that it could take advantage of features like multitasking and the Flex model Samsung has introduced with its latest foldable devices. Then there's the question of apps, and whether they'll have to be retrofitted to work with a new form factor. In other words, are there any trade-offs in brightness, HDR, color and screen refresh rate that a more conventional phone wouldn't have to make. But he also wants to know about any trade-offs LG has had to make in order to produce such a flexible screen. Greengart's looking for answers on durability and screen size. Hinges allow foldable phones like the Z Flip to flip open, but they can also be the source of mechanical issues. With the moving parts that a rollable screen entails, we’ll need to see how LG and others can ensure the devices keep working. Samsung fixed the problem, but only after delaying the launch of that phone. The original Galaxy Fold, for example, left a small gap that could allow dust and other particles through that could damage the screen. An early stumbling block for foldable phones involved the phone’s hinges - crucial for making the screen fold in two, but vulnerable to other issues. That last point is not an inconsiderable one. ![]() ![]() 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. Still, there remain plenty of blanks for LG to fill in if its rollable phone is going to convert the positive buzz from a CES teaser into a successful product launch. A screen that doesn't need to bend, but rather roll into place is unlikely to have those. " have creases and are twice as thick as a basic bar phone," said Greengart, noting the visible lines across even well-regarded foldables like the Z Fold 2 and the Galaxy Z Flip. As impressive as folding phones like the Galaxy Z Fold 2 are, you can still see creases in the display.
