Samsung says that its PMOLED business is losing its profitability, so they have to consider their option. They think they will change the production from PMOLED panels to OLED lighting panels. Another option is to shut down those lines.
Samsung already began R&D on white-light OLEDs, saying that it won't take a large investment to turn the production lines into white-light panels.
ETNews Korea also reported the LG Chemicals are also thinking about white-OLEDs for lighting, and have began R&D as well. LGDisplay stopped making PMOLED last year.
