LG has just unveiled a screen that can bend in both directions: both inwards, but also outwards! An innovation that could well impact the folding smartphone market in a few years.
LG’s subsidiary dedicated to the manufacture of LG Display screens is present at Display Week, which has just opened its doors. Among the innovations unveiled, a catch in the eye: a screen that folds both inwards, but also outwards.
A screen that can bend inward and outward
LG Display has just unveiled at Display Week an 8.03-inch folding OLED touchscreen that can bend inward as well as outward. Information about this screen is scarce, but we know from the hinge that it can be bent ” more than 200,000 times without compromising its performance due to stable module structure“.
The manufacturer announces that its “folding structureis designed tominimize creases, thus providing a comfortable user experience“. ThroughGizmodowe also learn the definition and resolution of this mysterious screen: 2,480 by 2,200 pixels, or 413 pixels per inch.
Will the folding smartphones of the future bend in both directions?
With this innovation, we can imagine some things about folding smartphones. It’s possible that future models could bend in both directions, like the demo offered today by LG. This would mean that foldable phones of the same format as the Samsung Galaxy Z Fold 3 would do without the external screen and only keep the main folding screen.
This obviously raises the question of the solidity of these screens and their hinge. But by having only one screen in the inward folded position, the risks of damaging it in a pocket or dropping it would be lower.

Other formats exist, especially on the Samsung side
Samsung had unveiled other folding screen prototypes last year at the same show. Indeed, the Korean manufacturer had unveiled three new types of screens, which we reviewed at CES last January.
First, there was the Flex Slidable: a rollable and stretchable screen concept; you could scroll the screen on the right side to enlarge it. Then, the Flex S: a smartphone prototype with this time two folds, one outward, the other inward. By unfolding it completely, we could take advantage of a surface three times larger. Finally, Samsung had presented the Flex G: also a prototype, with three screens placed side by side, like a three-fold wallet. Other brands are obviously in research and development on folding screens and have already unveiled prototypes; we know for example that TCL or Xiaomi are working on it.
The common point of these prototype screens is that their hinge could only turn to one side. LG’s feat here is that the manufacturer has managed to create a hinge that can bend a screen in either direction. If in terms of the number of folds, the Z Fold 3 does as much as the prototype presented by LG, one can wonder about the solidity of the screen presented at Display Week.
