OLED devices typically include a back electrode that reflects both emitted and incident ambient light. The reflected ambient light reduces the contrast ratio of OLED displays, reducing the visibility and image quality of the display. A variety of techniques for improving OLED ambient contrast are described and measurements of their effectiveness are discussed together with any impact on other OLED performance characteristics.
