Abstract:
An organic light-emitting diode (OLED) structure includes a stack of OLED layers that includes a light emission zone having a planar portion, and a light extraction layer formed of a UV-cured ink disposed over the light emission zone of the stack of OLED layers. The light extraction layer has a gradient in index of refraction along an axis normal to the planar portion.
