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 and liquid crystal display 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. (Yonhap News)
