In 2021, we reported that two researchers working at Samsung Display were convicted of handing over OLED technology to other companies, and are being sent to prison for two years. Representative and directors of the company that bought the technology was also sent to prison and the company was fined. The technology in question relates to Optical Adhesive Materials used in OLED production processes. The arrest of these employees was reported earlier in 2020.

It is now reported that another employee of Samsung Display, also involved in that case (seems to be he was the main organizer of the outfit) fled Korea following his indictment, but has now returned voluntarily to Korea and has been arrested and is now bring charged with violating unfair competition laws in Korea.

According to reports, Kateeva's QD-OLED printing project saga is not over. Samsung Display tested the company's latest printers, but these failed the tests and Samsung Display will not but these printers. SDC planned to replace the currently-used Semes' printers, which also suffer from low performance.

Samsung Display is also not committed yet to expand its QD-OLED production lines, which means that in any case it does not need to buy new printers for production expansion. Earlier reports suggested that SDC wanted to upgrade it current capability for higher density (to reach 8K TV printing), so this may be the reason behind the testing of Kateeva's new printers.

The second display is a 14" 2.8K (2880x1800, 240 PPI) inkjet printed hybrid OLED. This is the first time that CSoT has printed a laptop AMOLED display. It uses an IGZO (Oxide-TFT) backplane, and offer a variable refresh rate (30-120Hz) to expand the battery life. This display was first shown last month, when TCL stated it is on track to start mass producing OLEDs using an inkjet printing process in the second half of 2024.

Germany-based OLED lighting developer Inuru inaugurated its new OLED lighting panel production line, the "Dragon Factory", in Wildau near Berlin, Germany. This is an important milestone for Inuru, which is focusing on medication packaging and entertainment applications. The production line is now ready, but it will probably take some time to ramp-up and achieve full-scale production.

Inuru produces its OLED lighting panels using an inkjet printing process, which it says educes production costs by around 90% compared to conventional (evaporation-based) processes.
