Abstract
Methods of making an integrated barrier stack and optical enhancement layer for protecting and improving the light out coupling of encapsulated white OLEDs are described. The method includes optimizing the thickness of various layers including one or more of the plasma protective layer, the initial organic layer, the initial inorganic barrier layer, and the inorganic barrier layer and polymeric decoupling layer for the barrier stack. The thickness is optimized for at least one of total efficiency, or intentional color point shift so that the encapsulated OLED has enhanced light outcoupling compared to the bare OLED.
