Samsung's 'Unbreakable' OLED Display Gets Certified (theverge.com) 68

Posted by BeauHD from the displays-of-the-future dept.
Samsung Display, a subsidiary of Samsung Electronics, just introduced a flexible OLED panel that has a transparent plastic cover already attached, emulating the properties of glass but retaining the screen's innate flexibility. The screen is so durability that it's been certified by UL (formerly known as Underwriters Laboratories). The Verge reports: Samsung, describing the new panel as unbreakable, reports that it has withstood UL's military-standards tests of 26 successive drops from a height of 1.2 meters (close to 4 feet) as well as extreme temperatures as high as 71 degrees Celsius (159.8 degrees Fahrenheit) and as low as -32 degrees Celsius (-25.6 degrees Fahrenheit). The OLED display "continued to function normally with no damage to its front, sides, or edges," we're told, and Samsung even went further by performing a successful drop test from 1.8 meters (6 feet).

    I've seen this over and over and over again. I'm never buying any sort of OLED phone until either they can get degradation under control, or they've literally driven LCD phones off the market.

      If you use your phone 16/7 then OLED is probably a bad choice, not because the screen become very degraded but due to the uneven degradation mentioned in that article. Most people don't use their screens at maximum brightness and have the screen off most of the day and then OLED is a reasonable choice.

      OLED looks a million times better than LCD, even after 3 years of use.

        Maybe, if I could see the image on the screen past all of the burnt in TV station logos, the sunlight, the (unevenly) faded colours and the screen constantly fidgeting around to try to prevent burn in.

        I think I'll stick with my LCDs as they last practically forever and if the backlight ever does wear out, I can easily replace it.

      Yet it's still hard to go back to LCD once you're used to OLED. My Galaxy S2 had some noticable burn-in after 2 years, all other phones after that fared much better though. Current S8 of 1.5yrs looks like new and watching netflix/plex on it is nothing short of amazing.

    • .... whose display quality doesn't become lousy after 6-12 months of usage?

      Yes, basically all of them other than the pieces of shit listed in the article and that crappy Pixel thing Google released.

      Though my Galaxy S4 is showing very minor signs of burn-in after 5 years.

    If they didn't put any cover at all on it, it should also have the same unbreakable properties. Or if the screen cover were just cellophane or plexiglass. Glass is used in large part because it is scratch resistant, chemical resistant, and it can be thin for less optical distortion. I've heard nothing about it's other relevant properties.

    Let's see how well it survives such drops once it's attached to a non-flexible and heavier phone.

  • > Celsius (159.8 degrees Fahrenheit) and as low as -32 degrees pfft... -32C is a cold day in Montreal, but not unheard of at all... Last winter the pleather case for my raybans shatterred when I got my sunglasses out of it in the morning. seems like *military specs* doesn't include the arctic (and Montreal is south of Seattle, not even close to arctic.) I would worry about such a display if it we ever left overnight in the car.
    • I'm just curious, was your pleather case military spec'd?

    • It's very rare when it's -32C or below in Montreal. Last winter, the coldest temperature was on January 14 with -27C.

      Since 1941, there was a total of 8 days with -32C or below (Dorval airport) :

      Jan 15, 1957 with -37.8
      Jan 4, 1981 with -35.2
      Feb 15, 1943 with -33.9
      Jan 3, 1981 with -33.5
      Feb 16, 1943 with -33.3
      Dec 25, 1980 with -32.4
      Dec 20, 1942 with -32.2
      Feb 10, 1951 with -32.2

      • My car was reporting "is a cold day, but not unheard of" ... try Edmonton (january 2018 extreme was -34.6, February minimum was -40.1 ( http://climate.weather.gc.ca/c... [weather.gc.ca] ) or Whitehorse, or Longyearbyen, or Murmansk, or Tuktoyaktuk, or... there are a lot places people live that are colder than Montreal is the point. -32C is not a minimum temp that makes much sense for people living near the poles or even in northerly cities or at some altitudes.

    • Military grade temperature range is -55 / +125 C (junction temperature). Of course, there can be adaptations to other temperature ranges... Here, they probably used the standardized military test methods, but with a more limited temperature range.

  • Did the detailed article list the weight of the screen? Curious how it might compare to existing parts. Seems to me to be a bit bulkier/heavier.

  • >"The screen is so durability [sic] that it's been certified by UL"

    "Durability" means many things. A plastic screen can give and bend. So yes, it might be generally, "unbreakable". But plastic is much, much, much softer than glass. So instead of a broken screen, you end up with a scratched-up-to-hell screen. So that doesn't mean it is more "durable" than high-tech glass.

    "Which is better?" (AKA "Pick your poison") Might be the appropriate question.
