LG Display announced in a press conference in Seoul that the korean company had infringed seven of its patents on OLED panel technologies.

The company filed a damage suit (against Samsung) to protect its indigenous technologies that took an enormous amount of money and people to develop over a long period of time,” an LG official told the press conference.

“Samsung Electronics and Samsung Mobile Display must immediately stop using patented technologies and pay due amount in damages for their use of patented technologies,” the official said.

LG Display submitted to the Seoul Central District Court, LG Display alleged that Samsung infringed seven patents in five of its mobile Internet devices ― the Galaxy S3, Galaxy S2, Galaxy S2 HD, Galaxy Note and Galaxy Tab 7.7.

LG Display explained that the patents in question ― KR0583252, KR0774911, KR0581101, KR0641738, KR0555308, KR0754484 and KR0939206 ― are related to panel designs, circuit technologies and OLED structures.

It’s too early to talk about expanding the requests for injunctions internationally. But yes, it’s certainly an option we could take. We aren’t expecting anything less than a sincere apology from Samsung,” said Lee Bang-soo, LG Display’s senior vice president.
