摘要：
An organic light-emitting diode (OLED) structure includes a substrate, a dielectric layer on the substrate having an array of well structures with each well structure including a recess with side walls and a floor and the recesses are separated by plateaus having rounded top surfaces, a stack of OLED layers covering at least the floor of the well, and a light extraction layer (LEL) in the well over the stack of OLED layers.
