Abstract: Embodiments of a flexible electroluminescent (FEE) device are described. An FEE device includes a device stack with a quantum dot (QD) film configured to generate a first light having a first peak wavelength and a flexible substrate configured to support the device stack and emit a first portion of the first light. The FEE device further includes an encapsulation layer disposed on the device stack and an outcoupling layer disposed on the flexible substrate. The encapsulation layer can be configured to provide mechanical and environmental protection to the FEE device from moisture or oxygen. The outcoupling layer can be configured to prevent total internal reflection of a second portion of the first light within the flexible substrate and extract the second portion from the flexible substrate. The outcoupling layer can be further configured to eliminate air gaps at an interface between the outcoupling layer and a surface to be illuminated by the extracted second portion in response to the FEE device being substantially conformally placed on the surface.
