Underwriters Labs Certifies Samsung’s ‘Unbreakable’ Smartphone Panel


Underwriters Laboratories (UL), an official testing company for the Occupational Safety and Health Administration (OSHA) of the U.S. Department of Labor, has today certified Samsung Display’s new flexible OLED panel developed with an ‘unbreakable’ substrate and an overlay window securely adhered to it. 

According to Samsung, the newly developed display can also be used in other electronic products such as display consoles for automobiles, mobile military devices, portable game consoles and tablet PCs for e-learning. 

Samsung’s unbreakable display passed UL’s rigorous real-time durability test that is based on military standards set by the U.S. Department of Defense. Even in a 6 feet drop test, which is significantly higher than the U.S. military standard, the unbreakable panel operated normally with no sign of damage.

“The fortified plastic window is especially suitable for portable electronic devices not only because of its unbreakable characteristics but also because of its lightweight, transmissivity, and hardness, which are all very similar to glass,” said Hojung Kim, general manager of the Communication Team, Samsung Display Company.

After a drop test administered at 1.2 meters (nearly 4 feet) above the ground 26 times in succession, and accompanying high (71 degrees) and low (-32 degrees) temperature tests, the Samsung unbreakable panel continued to function normally with no damage to its front, sides or edges.
