SEOUL--South Korean display maker LG Display Co. (066570.SE) said Friday it filed an injunction seeking to ban the sales of a tablet computer produced by Samsung Electronics Co. (005930.SE), alleging the panels inside the tablet infringe LG patents.

The injunction request is the latest development in the ongoing patent brawl between LG Display and the affiliate of Samsung Electronics that manufactures screens used in smartphones, tablets and televisions. It also signals intensifying competition as the two companies jostle for market share.

The injunction follows a lawsuit filed by Samsung Display Co. on Dec. 7, which alleged that LG infringed seven of Samsung's liquid crystal display patents. LG, which filed the injunction with the Seoul District Court on Wednesday, is aiming to block the sales of the Galaxy Note 10.1 tablet computer.

"Through this action, LG Display seeks to completely stop the sale, manufacture, and importation of [the] infringing Samsung product," the South Korean display maker said in an emailed statement. LG Display is also seeking damages of 1 billion won ($933,000) per day in the event of "continued non-compliance."

Shim Jaeboo, a vice president of Samsung Display, said the company didn't infringe LG's patents and it will respond to "unjustified claims" made by LG.

The patents at issue are LG Display patents related to the viewing technology embedded in the display panels, which help enhance the visual quality regardless of the viewing angle.

LG Display and Samsung Display have also been embroiled in another lawsuit over patents related to organic light-emitting diode display technology. OLED displays first emerged in car radios in the 1990s but in recent years improved in quality enough to be used in cellphones, tablet computers and television sets.
