Samsung OLED panel passes 'unbreakable' test
Samsung has announced its unbreakable smartphone panel has been officially verified by UL (Underwriters Laboratories). Samsung Display said that in addition to being used on smartphones, the display could be used as a display for automobiles, portable game consoles and tablet PCs.
Samsung Display developed the flexible OLED panel with an unbreakable substrate and an overlay window securely adhered to it. Current-generation flexible display products attach a glass-covered window to their display that often breaks when severely impacted.
“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 Communications Team at Samsung Display.
According to UL, the unbreakable display developed by Samsung Display passed the rigorous real-time durability test that is based on military standards set by the U.S. Department of Defense. After a drop test administered at 1.2 metres (nearly 4ft) above the ground 26 times in succession, and accompanying high (71 degrees Celsius) and low (-32°C) temperature tests, the Samsung unbreakable panel continued to function normally with no damage to its front, sides or edges.
Even in a subsequent 1.8M (nearly 6ft) drop test – significantly higher than the U.S. military standard – Samsung Display’s unbreakable panel operated normally with no sign of damage.
