LG Display sues Samsung over OLED patents

South Korea's LG Display, the world's number two maker of liquid crystal displays (LCDs), has filed a lawsuit against Samsung Electronics, for allegedly violating its patents on organic light-emitting diode (OLED) panel technologies.

In a press conference in Seoul, LG Display accused Samsung Electronics of infringing seven of its OLED patents on five products, noted an article Thursday by Yonhap news agency. The products include Samsung's Galaxy S-series smart phones and tablet computer Galaxy Tab.

"The company filed a damage suit 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 said at the press conference.

LG Display did not reveal how much in damages it was seeking.

Samsung has called LG's lawsuit a scheme to overcome its own difficulties, and said it will file a countersuit if necessary, according to the report.

Earlier this month, the tech giant had sought an injunction against LG over technology leaks after workers at Samsung Mobile were arrested for allegedly leaking information to the company.

Samsung is also currenly embroiled in a legal battle with Apple, where it has been accused of infringing Apple patents with some of its mobile devices, including the Samsung Galaxy S and the Galaxy Tab 10.1. The South Korean firm is disputing the US court's verdict ordering it to pay over US$1 billion in damages to the Cupertino-based firm.
