Abstract
A device including an organic light emitting diode and a dielectric layer is provided. The dielectric layer provides additional distance between a reflector and the organic emission region, leading to improved reduction in non-emissive modes and enhanced efficiency.
Claims16
A device comprising:
- a substrate;
- an organic light emitting diode (OLED) disposed over the substrate, the OLED comprising an organic emissive layer disposed between a first electrode and a second electrode;
- a reflective layer comprising a reflective material disposed in a stack with the OLED;
- and
- a dielectric layer comprising a dielectric material disposed in a stack with the OLED and the reflective layer.
