LG accuses Samsung of infringing display patents

SEOUL (AFP) - South Korea's LG Display, one of the world's top flat-screen TV makers, said on Thursday it had filed a patent infringement suit against Samsung Electronics over the use of advanced displays.

LG Display, a sister firm of LG Electronics, accused Samsung Electronics and Samsung Display of infringing seven of its patents on organic light-emitting diode (OLED) technology.

The company claimed that five of Samsung's products, including its global hit Galaxy S-series smartphones and tablet computer Galaxy Tab 7.7, infringed its patents.

"This lawsuit has been filed both to enforce LG Display's intellectual property rights and promote fair competition," it said in a statement. It added it would seek an unspecified amount of damages and a permanent injunction against the sale of infringing devices.
