According to South Korean media reports, Samsung showed that two researchers and an external partner were arrested. South Korean prosecutors accused them of commercial espionage and leaked OLED technology to Chinese enterprises, causing Samsung millions of dollars in losses.
It is reported that the case involves Samsung's ink-jet printing technology used to produce OLEDs. South Korean prosecutors believe that the two researchers leaked the process specifications of Samsung display's test in the second half of last year.
Inkjet printing technology is regarded as the future of mass production of OLED for many reasons, but the primary factor is cost. Analysts estimate that making a contemporary 65 inch 4K TV with an inkjet printer is 20% cheaper than the current WOLED process.
Samsung has invested more than 10 billion won (8.5 million dollars) over the past three years to develop printing specifications. In the face of increasingly fierce competition, mass production is the only way for Samsung display to remain competitive in the OLED market.
Samsung is expected to be the first company to use inkjet printing in its OLED production business as early as Samsung said. Besides Chinese mainland, Taiwan and Japan are also studying the same technology.
