apparently LWLG passed with only 2nd generation encapsulation!! and the press release said we had a breakthrough with 4th generation encapsulation as well, here
In addition, the company's process development team has achieved a significant breakthrough with its fourth-generation atomic layer deposition (ALD) encapsulation material, recently demonstrating an oxygen transmission rate (OTR) of 1.4 ×?10?6?g/m²/day-approaching the measurement limit of state-of-the-art OTR instrumentation. This performance far exceeds the "gold-box" standard of 7 ×?10?6?g/m²/day for lifetime reliability.
