SEOUL, March 21 (Yonhap) -- LG Electronics Inc. on Thursday accused Samsung Display Co. and Samsung Electronics Co. of illegally using its technology and demanded the two companies pay for the patents, the latest development in the Samsung-LG display feud.
Samsung Display and LG Display Co., the world's two biggest display makers, have been embroiled in a patent tussle over organic light-emitting diode (OLED) and liquid crystal display (LCD) technologies that later expanded to their TV-making affiliates Samsung Electronics and LG Electronics.
In a statement, LG Electronics said it is "doubtful" about Samsung Display's decision to drop a patent suit against the company and said it will carefully consider the suggestion.
LG Electronics also called for compensation for the use of its patent technologies, adding it is ready to hold talks on the payment issue.
The move marks a twist in the display feud between the two tech giants that seemed to be heading toward a peaceful end.
After filing requests for a sales ban on each other's products and use of certain technologies, the two companies recently agreed to make a compromise in a meeting organized by the commerce ministry.
In February, Samsung Display dropped an injunction aimed to block LG Display from using its OLED technology. In response, LG Display nullified its sales ban request on Samsung's Galaxy Note 10.1 devices.
Samsung Display also recently decided to drop a patent suit against LG Electronics over LCD technologies, raising hopes the two sides will reach the end of the long-running legal battle.
