Samsung Display has just announced the next step up from that: a flexible OLED panel that has a transparent plastic cover already attached, emulating the properties of glass but retaining the screen’s innate flexibility. Without the need for glass, this screen has proven rugged enough to be certified by UL (formerly known as Underwriters Laboratories) for its durability. > Samsung, describing the new panel as unbreakable, reports that it has withstood UL’s military-standards tests of 26 successive drops from a height of 1.2 meters (close to 4 feet) as well as extreme temperatures as high as 71 degrees Celsius (159.8°F) and as low as -32 degrees Celsius (-25.6°F). The OLED display “continued to function normally with no damage to its front, sides, or edges,” we’re told, and Samsung even went further by performing a successful drop test from 1.8 meters (6 feet).
