Abstract
An organic light emitting diode (OLED) device includes an anode layer upon a DBR (Distributed Bragg Reflector) stack such that the anode layer is modified by creating lens-like features on its surface. The OLED device also includes a planarizing layer on said anode layer, said planarizing layer filling in said lens-like features, said planarizing layer providing a flat uniform surface for the deposition of other layers thereupon.
