Abstract

Organic light emitting diode (OLED) devices are disclosed that include a first layer; a backfill layer having a structured first side and a second side; a planarization layer having a structured first side and a second side; and a second layer; wherein the second side of the backfill layer is coincident with and adjacent to the first layer, the second side of the planarization layer is coincident with and adjacent to the second layer, the structured first side of the backfill layer and structured first side of the planarization layer form a structured interface, the refractive index of the backfill later is index matched to the first layer, and the refractive index of the planarization layer is index matched to the second layer.
