Organic light emitting device with improved light extraction |
| 摘要 |
The invention provides an organic light-emitting device (OLED) comprising: a transparent substrate; a first, transparent electrode layer arranged on said substrate; one or more organic light-active layers arranged on said first electrode layer; a second electrode layer arranged on said one or more organic light-active layers; and a discontinuous layer comprising discrete, randomly distributed nanometer-sized domains of a low refractive index material, arranged between said first electrode layer and said one or more organic light-active layers. The discontinuous layer of discrete, randomly distributed nano-sized domains increases the light extraction efficiency of the OLED. |

1. An organic light-emitting device (OLED) comprising:
a transparent substrate; a first, transparent electrode layer arranged on said substrate; one or more organic light-active layers arranged on said first electrode layer; a second electrode layer arranged on said one or more organic light-active layers; and a discontinuous layer comprising discrete, nanometer-sized domains of a low refractive index material, arranged randomly distributed, in a plane of the OLED between said first electrode layer and said one or more organic light-active layers. |
