Samsung Display, the subsidiary at Samsung Electronics to research and develop new displays for the company has just announced an ‘unbreakable smartphone display’. The company added that its “recently-developed, unbreakable smartphone panel” was just certified by Underwriters Laboratories (UL). UL is the official testing company for the Occupational Safety and Health Administration (OSHA) of the U.S. Department of Labor. Being certified by the official testing company to check the quality of the product for the federal government of United States is considerable in its own right. However, just to give some perspective about how extensive the certification process was, UL issued a statement sharing details about how the display was certified.
According to the statement, UL put the display under “real-time durability test” that was based on the military standards established by the Department of Defense in the United States. The testing company dropped the display “26 times in succession” from the height of 4 feet or 1.2 meters which is around the typical level where most smartphone users would hold their smartphones while standing upright. The display was also put under extreme temperatures to check if it works without any issue. According to the report, the display continued to work normally without any damage to the front, edges, or sides.

Samsung also pointed out that the unbreakable display continued to operate normally without any sign of damage when dropped from “nearly 6 feet” or 1.8 meters, a height “significantly higher than the US military standard”. Samsung Display clarified that it is using a “fortified plastic window” along with the flexible OLED panel and ‘an unbreakable substrate’. In contrast, the current generation of the flexible OLED panel comes with a glass-covered window which often breaks on severe impact. According to a report by Android Central, Samsung added that this is different from the usual display panels where smartphone makers have covered their displays with synthetic sapphire.
The report goes on to state that the display with synthetic sapphire is “extremely difficult” to break when properly reinforced from the hardware of the device. Samsung claims that fortified plastic has very similar hardness and “transmissivity” about how RD and light can pass through the panel when compared to glass.
Samsung Display has not issued any details on when this unbreakable glass panel will be available for commercial smartphones which means that it is unlikely that the company may pack it with its upcoming Galaxy Note 9 or even next year’s Galaxy S10 range. Last but not the least, the company added that the display could be used at a number of other places including display consoles on automobile, mobile devices used by the military, tablet PCs, and even portable gaming consoles.
