Zusammenfassung:Embodiments described herein relate to spatial optical differentiators and layer architecture of adjacent functional layers disposed above or below organic light-emitting diode (OLED) display pixels. A functional unit for an electroluminescent (EL) device pixel includes a spatial optical differentiator disposed adjacent the EL device pixel. The spatial optical differentiator is configured to selectively reflect and transmit light based on an incident angle of light upon the functional unit. For top-emitting OLED, the functional unit includes a thin film encapsulation (TFE) stack disposed over the spatial optical differentiator. For bottom-emitting OLED, the functional unit includes the spatial optical differentiator disposed above at least one of a planar layer or an isolation layer. Also described herein are methods for fabricating the functional unit.
