LG and Samsung have resolved their lawsuits regarding OLED patents. In September 2012, LG filed a lawsuit against Samsung regarding OLED display and filed a countersuit in November 2012. The two companies have settled outside of court after a government ministry persuaded the CEOs of LG Display and Samsung Display to meet at a hotel in Seoul.
When LG filed the lawsuit, they had attempted to get a sales ban on Samsung devices like the Galaxy Note and Galaxy Tab 7.7. Samsung had accused LG of violating the copying plate-to-line (PLS) switching technology without paying royalties.
