Abstract:
An organic light-emitting diode (OLED) device, comprising: a first electrode and a second electrode. One or more organic layers are formed there-between, including an organic light-emitting layer. The second electrode is transparent. A contrast enhancement element is formed on a side of the second electrode, opposite the organic layer, and has a geometric area for controlling ambient light contrast ratio of the OLED device.
