The Black Electrode, a control layer sandwiched in between a thin metal layer and a reflective metal layer, is designed to reduce the reflection of the ambient light. By connecting the thin metal layer and the reflective metal layer, the control layer may be used without considering its work function. The average reflectivity of OLED with the black electrode could be reduced to be 5.9%, lower than that of conventional device with a circular polarizer.
