The manufacturer says the screens also subsequently survived a drop from 6' (1.8 m) and kept on ticking.
Rather than go with a super-hard glass, Samsung is using fortified plastic that's flexible.
However Samsung thinks that they might have found the solution as the company is now boasting that they have developed an "unbreakable" OLED display panel that has been certified by the UL (Underwriters Laboratories), which for those unfamiliar is an official testing company for OSHA, the Occupational Safety and Health Administration of the U.S. Department of Labor.

The first of the challenges involves playing 14 matches in the Battle Royale mode, which you can probably manage easily . Some minor changes have made Playground Mode more fun, such as allowing gamers to switch teams and reduced spawn times.
There is now no information available as to when the display will begin appearing in Samsung smartphones. Outside of smartphones, Samsung says its flexible display will find residence in other electronic devices, such as display consoles for automobiles, portable game consoles, tablets, and mobile military devices. First up was the drop testing, during which it was let go from a height of 4 feet - not just once, but 26 times in a row.
Along with its impact tests, the new panels were subjected to extreme temperatures, ranging from a high of 71C (159.8F) to a low of -32C (-25.6F) while still continuing to function normally. In fact, according to Samsung, it's many times more durable than glass and unlikely to break during day-to-day use. Samsung Display's general manager of the communication team, Hojung Kim, said this fortified plastic window is similar to glass in terms of weight, transmissivity and hardness, so it should be able to replace glass without too much hassle. Even in subsequent 1.8 m (~6 ft.) drop tests, which is significantly higher than the USA military standard, the unbreakable panel operated normally with no sign of damage.
Samsung hasn't revealed when or which of its smartphones might in line for the display, but you can nearly guarantee that it will show up on a future Galaxy S10 Active. We'll just have to wait and see. Samsung sees it as having a use in auto displays, military devices, tablets and portable games consoles.
