Enhanced moisture barrier performance for ALD-encapsulated OLEDs by introducing an organic protective layer

The bi-layered inorganic/organic of AMO + CYTOP has superior water vapor transmission rate as 1.05 × 10⁻⁶ g m⁻² day⁻¹ at 60 °C and 100% R.H., and the encapsulated OLEDs device produces no black spots under harsh environment at 85 °C & 85% R.H. for 250 h.
