AP Systems to supply Thin Film Encapsulation to Samsung Display QD-OLED line

DIGITimes China reports [LINK] that Samsung Display is building a large-scale quantum dot organic light-emitting diode (QD-OLED) panel pilot production line. The line is scheduled to be finished in December 2018 and will be activated after 6 months (mid 2019). According to the report the supply ration from Korean equipment manufacturers has increased significantly for this line.

As an example the the report claims that AP Systems beat Applied Materials to supply the Thin Film Encapsulation (TFE) equipment. AP Systems has previously supplied TFE equipment for the 8th generation RGB OLED TV panel production line (V1) of Samsung Display. In the past Samsung Display has used TFE equipment supplied by Applied Materials in the 6th generation flexible OLED production line, but has now switched and for its AP Systems in this 8th generation QD-OLED test production line.

Also according to the report, the PECVD equipment will be supplied by Wonik IPS from Korea whereas the blue OLED material evaporation equipment will be supplied by Canon Tokki (Japan) and the red and green QD material inkjet printing machine will come from Kateeva (USA).
The KORONA™ TFE System running PEALD with "Multi-linear Nozzle" technology and ICP antenna design technology (high density/low damage plasma).
For TFE AP Systems are using a Plasma enhanced Atomic Layer Deposition (PEALD) technology on their KORONA™ TFE System. The system is capable of depositing a film structure that acts as a sealant to prevent oxygen and moisture penetration into OLED device. Based on a 1000Å, SiNx/SiOx multi-layer structure the Water Vapor Permeability is less than 5e-5 g/m2/day.
According to AP Systems they can also apply the film as a flexible sealant to realize flexible, rollable, and foldable displays.
