LG Display Co said on Friday that it had asked a Seoul court to ban the domestic sale of Samsung's Galaxy Note 10.1 tablet computer, citing alleged patent infringements.
In the injunction LG Display accuses Samsung of infringing three of its patents on LCD panels used in the Galaxy Note.
LG Display seeks to completely stop the sale, manufacture and importation of the infringing Samsung product, the firm said.
The company also said it would request compensation amounting to 1 billion won (US$933,000) per day in the event of continued non-compliance.
The two companies have been in a patent row since September when LG Display filed suits against Samsung Electronics and Samsung Display for allegedly infringing patents on seven organic light-emitting diode (OLED)-related technologies.
LG Display said that five of Samsung's products infringed its patents.
Later the same month, Samsung filed a court complaint accusing LG of luring away senior Samsung OLED researchers even though they had signed contracts preventing them working for a rival.
