In the past year or so, much have been said about Samsung's plans to build a 8-Gen OLED IT production line, as the company wants to expand its capacity for monitors, laptops and tablet OLED displays.
Samsung plan for a full-cut 8-Gen line
As this is the first such production line, SDC had two ongoing R&D projects: one with Ulvac, that used full-cut vertical OLED deposition, and another with Canon Tokki, that used half-cut horizontal deposition. According to the latest reports from Korea, SDC decided to prioritize the Canon Tokki half-cut project, as the technology is more mature and is more likely to finish as per Apple's roadmap.
Samsung's Canon Tokki project uses a dual-stack (tandem) architecture, as opposed to a single-stack architecture that was developed with Ulvac. This is per Apple's request as it wants panels with extended lifetime.
