In November 2018 it was reported that South Korean prosecutors indicted a group of 11 executives and employees of Korea-based Toptec, a Samsung Electronics supplier, accusing them with leaking Samsung's flexible OLED technology to Chinese display makers.

According to new reports from Korea, the South Korean government has now decided to restrict the export of OLED production equipment. Korea will designate OLED equipment as a "national core technology" which means that any export, acquisition or merger deals will require government approval. Under the current law, display panel design, process, manufacturing and drivers are already designated as national core technologies, and Korea wants to add production equipment as well to prevent another case like Toptec from happening.

The government also aims to make the Korea chemical industry and 10 more industries as sectors that will also be regulated as a national core technology.
