Singapore — On Friday, Samsung Display, a subsidiary of Samsung Electronics, said its recently developed unbreakable, bendable screen has passed safety testing in the US, a step that will help the South Korean firm market the product.

Samsung Display, an Apple supplier, said the screen can be used in devices such as smartphones, tablets, portable gaming machines and consoles in automobiles.

The firm and rivals, such as compatriot LG Display, have long been developing flexible screens as they compete to make more innovative devices. Samsung Display’s new screen is protected by plastic rather than glass, increasing flexibility and making it practically unbreakable, the firm said on its website.

Importantly, the screen has improved transparency, almost akin to glass, allowing it to be installed on devices used close-up, such as smartphones, a Samsung Display official said.

The screen has been certified by Underwriters Laboratories, a testing firm for the US occupational safety and health administration, after tests that involved being dropped 26 times from a height of 1.2m, Samsung Display said. After testing, the screen continued to function normally, with no damage to its front, sides or edges, the firm said.

US certification bestows such credibility that marketing can begin worldwide, not just in the US, the Samsung Display official said.

Samsung Electronics has been widely expected to introduce a device with foldable screen since its mobile chief in September said such a device was being developed and needed to overcome technological hurdles before possible release in 2018.

Such a device is likely to help ease concerns that Samsung Electronics, the world’s largest smartphone manufacturer, is running out of ideas to support sales of its premium Galaxy handsets as its smartphone sales growth slows.

Shares in Samsung Electronics closed unchanged on Friday, compared to a 0.3% rise in the broader market.
