Abstract
An organic light-emitting diode (OLED) device includes a substrate, a well structure on the substrate with the well structure having a recess with side walls and a floor, a lower metal layer covering the floor and side-walls of the well, an upper conductive layer on the lower metal layer covering the floor of the well and contacting the lower metal layer, the upper conductive layer having outer edges at about an intersection of the side walls and the floor, a dielectric layer formed of an oxide of the lower metal layer covering the side walls of the well without covering the upper conductive layer, a stack of OLED layers covering at least the floor of the well, the upper conductive layer providing an electrode for the stack of OLED layers, and a light extraction layer (LEL) in the well over the stack of OLED layers and the dielectric layer.
