Samsung to use a single-stack structure in its first 8-Gen OLED production line

Last Month Samsung Display confirmed that Samsung is now building a 8-Gen (2200x2500 mm) OLED production line, that will begin production in 2024.

It is expected that the new line will mostly produce panels for IT devices (laptops and tablest) and also for automotive applications. Many believe that these applications will adopt tandem stack structure to increase brightness and lifetime. According to a new report, Samsung's new line will adopt a single-stack structure, and not a dual-stack one.

An 8-Gen line, that will enable deposition on a complete substrate is a major technology challenge compared to current OLED lines, and it seems as if Samsung is not ready to also implement a dual-stack structure. Samsung does plan, however, to leave space in the factory so it could upgrade the process to a dual-stack structure in the future (most of the change involves extra organic vacuum deposition chambers).

According to DSCC, there are over 10 8.5-Gen OLED lines under consideration now in the industry, as demand for OLED panels for laptops, tablets and monitors is o the rise. Samsung is the current leader in OLED IT displays.

Omdia estimates that in five years, OLED penetration into the laptop display market could exceed 10%. The total laptop display market in 2021 amounted to 280.85 million panels.

Samsung count on development of new more durable OLED emiters, so single stack may be sufficient
