Abstract
An organic electroluminescent device provides reduced reflectivity to increase contrast and improve display quality. The organic electroluminescent device includes a substrate, a first electrode over the substrate, at least one organic electroluminescent layer on the first electrode, a second electrode of a transparent conductive material on the at least one organic electroluminescent layer, a top passivation layer on the second electrode, and a compensation layer including at least an antireflection coating material or an antiglare coating material.
Claims28
An organic electroluminescent device, comprising:
- a substrate;
- a first electrode disposed over the substrate, the first electrode causing optical interference of incident light;
- at least one organic electroluminescent layer disposed on the first electrode;
- a second electrode disposed on the at least one organic electroluminescent layer, the second electrode including a transparent conductive material;
- a top passivation layer disposed on the second electrode;
- and
- a compensation layer disposed on the top passivation layer, the compensation layer including at least one of an antireflection coating material and an antiglare coating material.
An organic electroluminescent device, comprising:
- a substrate;
- a first electrode disposed over the substrate;
- a first compensation layer disposed on the first electrode, the first compensation layer including a material having conductive and light-absorptive characteristics;
- at least one organic electroluminescent layer disposed on the first compensation layer;
- a second electrode disposed on the at least one organic electroluminescent layer, the second electrode including a transparent conductive material;
- a top passivation layer disposed on the second electrode;
- and
- a second compensation layer disposed on the top passivation layer, the second compensation layer including at least one of an antireflection coating material and an antiglare coating material.
An organic electroluminescent device, comprising:
- a substrate;
- a first compensation layer disposed over the substrate, the first compensation layer including an organic insulation material having light-absorptive characteristics;
- a first electrode disposed on the first compensation layer, the first electrode including a first transparent conductive material;
- at least one organic electroluminescent layer disposed on the first electrode, the at least one organic electroluminescent layer defining a luminous region;
- a second electrode disposed on the at least one organic electroluminescent layer, the second electrode including a second transparent conductive material of a same or different material than the first transparent conductive material;
- a top passivation layer disposed on the second electrode;
- and
- a second compensation layer disposed on the top passivation layer, the second compensation layer including at least one of an antireflection coating material and an antiglare coating material,
- wherein substantially an entire lower surface of the first electrode contacting the first compensation layer, and wherein the first compensation layer is disposed substantially only in the luminous region.
