Samsung Display plans to produce single stack OLED panels

According to The Elec, Samsung Display is planning to produce single-stack OLED panels at its first 8th-generation OLED production line. If implemented, the cost of some devices using OLED screens in the future is expected to be further reduced.

According to reports, Samsung Display is already planning to build the first 8th-generation OLED production line. Compared with the 6th-generation OLED production line used by Samsung Display and LG Display, the glass substrate area of ​​the 8th-generation production line is larger, which has greatly increased from 1500×1850mm in the 6th generation to 2200×2500mm. The larger substrate area means that larger OLED screens can be manufactured at a more reasonable cost.

The single-stack OLED panel of Samsung Display will be produced in the first 8th generation OLED production line. According to people familiar with the matter, the full-cut vertical deposition machine developed by Samsung Display in cooperation with Japan’s Ulvac for the 8th-generation OLED production line has been serving single-stack OLEDs from the design concept stage.

As the name suggests, single-stack OLED refers to a single-layer red, green, and blue light-emitting layer, while two-stack tandem OLED has an additional light-emitting layer on this basis. The two-stack tandem OLED can make the screen have more brightness and service life, and it is more friendly to devices such as monitors and tablet computers that users need to replace for a long time. The single-stack OLED is suitable for mobile phones and other devices that users update quickly.

Although Samsung Display’s first 8th-generation OLED production line will be used to produce single-stack OLED panels, the production line also leaves enough room to be retrofitted to make two-stack tandem OLED panels, just by installing more vacuum deposition processes for organic materials.
After completion, this 8th-generation OLED production line will be able to provide a monthly output of 15,000 pieces, and it is also possible to increase production capacity later.
