Abstract
Optical components and devices are provided that include a substrate, a microlens array, and a barrier film system conformally covering the microlens array. An OLED may be optically coupled to the microlens array. The barrier film may provide protection to the microlens array or other components, without having a significant negative impact on outcoupling of light from the coupled OLED by the microlens array.
