The Samsung Galaxy Fold smartphone will have strengthened Corning Gorilla glass on the secondary, outside display. The Korean company confirmed this week that the outside display is not flexible with a plastic cover layer, like the inside folding display, but a regular smartphone screen. As a result, the Fold may suffer from broken glass when dropped too hard on a rigid surface (and eliminating one of the biggest advantages of foldable displays, that they can’t shatter). However, Samsung promises to repair any kind of drop damage for free in the first year after purchase, the company says in a press release.
Plastic on the inside
U.S. glass producer Corning, maker of the reinforced ‘Gorilla’ chemically strengthened glass, provides the cover for the secondary fixed display. It has a high overall crack-resistance, making it resistant to damage from everyday use. However, on the inner, large display of the Galaxy Fold, no glass is used, but organic light emitting diodes are printed on plastic. It’s a polymer substrate with flexible touch and cover layers added.
One of the biggest advantages of foldable displays, is that they can’t break like glass displays do. Most regular smartphones end up in the trash because their screens get shattered. Drop your expensive smartphone on the street and you’ll have a high probability of a broken display. Within one year, roughly 30 percent of iPhones will suffer accidental damage. With foldable displays, that should no longer be the case. But because the Galaxy Fold has glass on the outside, devices may still suffer from drop damage. Samsung are now offering a 1 year free repair guarantee for dropped devices with shattered displays.
