Abstract
A light extraction apparatus for an organic light-emitting diode (OLED) includes an OLED emitter (), a plurality of tapered reflectors (), and a spacer layer (). Each tapered reflector includes a first surface (), a second surface () opposite to the first surface and comprising a surface area larger than a surface area of the first surface, and at least one side surface () extending between the first surface and the second surface. The spacer layer () includes a first surface coupled to the OLED emitter and a second surface coupled to the first surface of each of the plurality of tapered reflectors. Light emitted from the OLED passes through the spacer layer and into the plurality of tapered reflectors. The at least one side surface of each of the plurality of tapered reflectors includes a slope to redirect light into an escape cone and out of the second surface of the corresponding tapered reflector.
