Samsung sues LG Display over OLED patents

Samsung’s legal team is taking a break from their ongoing battle with Samsung to go after another competitor. The Korean company that produces the Galaxy line of Android phones has filed a patent suit against a branch of the Korean company that produces the Optimus line of phones. Specifically, Samsung is going after LG Display on the basis that several patents pertaining to OLED screen technology should be deemed invalid.

The suit is only the latest volley in the lesser-publicized court battle over the OLED technology that forms the basis for Samsung’s line of Super AMOLED displays as found in such devices as the Galaxy S3. Back in September, LG Display sued Samsung over their use of OLED displays, claiming infringement.

Samsung is seeking to have seven patents granted by a Korean intellectual property tribunal rendered invalid on the basis that they simply aren’t innovative enough to warrant such rights. Voiding such patents could effectively end LG’s ability to go after Samsung on the basis of infringement.

OLED displays, which don’t require the backlight typical to traditional LCD displays and therefore allow for increasingly slimmer device design, have been a staple in Samsung’s flagship products. The company boasts the largest deployment of such displays on mobile devices, something that Samsung sees as a competitive edge. LG’s deployment of OLED technology has largely been relegated to their television business, so the suit at hand isn’t strictly about mobile. That being said, if LG comes out the victor it could create some problems for Samsung’s handset division.

    Samsung is going to get sued by Apple for their Suing patients!

    But seriously, LG makes much better LCD’s than Sammy and I feel this whole case is a lost cause.

    “Samsung’s legal team is taking a break from their ongoing battle with Samsung to go after another competitor.”….So samsung is battling itself? ;P

      Samsung is suing itself again?

  • longshot1056

    Might want to reread that first sentence, I didn’t know Samsung was suing itself nor that it was a competitor to itself. Not a jab at you just a simple mistake that was clearly meant to say Apple.

    As for the content, I’m honestly tired of hear about how Samsung is in a legal battle with yet another company. I;m sure there might be grounds for both side of the case, they’ll go to court 12 times and get nothing done, and then eventually they’ll sign some form of licencing deal. Samsung is becoming like Apple, albeit not nearly as bad yet but if they keep winning legal battles it could get a hell of a lot worse, and the legal battles will never end. everyone just needs to stop acting like 5-year-old’s and just accept start paying for what they owe and move on.

        She probably costs less than the TV.

        /end racist joke

    • peanutsrevenge

      Nah, not blow the roof off, but blow her clothes off.
      Blowing the roof off sounds pricey and the wrong kind of drafty.

    considering how strong Samsung has been spring oled technologies I am surprised lg is suing them about it. What, is lg going the way of Apple? Samsung makes it first just to get sued?

    • Duong Duc Ngo

      it is the other way around. LG has the patent for a reason.
