The Korean Supreme court put an end to a years-long legal battle between LG Display and Samsung Display, saying that SDC's employees and a chief executive of one of LG's suppliers are not guilty in IP theft.

The supreme court upheld the original ruling and dismissed the appeal. The case revolved around LGD's face seal encapsulation technology for OLED displays. The main issue in the legal case was whether leaked LGD documents were trade secrets. The employees and executives were first found guilty, but at a higher court they were found innocent as it was decided that the information was already widely known in the industry.

Over the years we have seen many legal battles in Korea, between Samsung and LG, and between Korean companies and Chinese companies, all revolving around OLED technologies and trade secrets.
