CLOSE ILLUMINATION SYSTEM |
| 摘要 |
Devices suitable for close illumination of an object are provided. Such a device includes a highly transparent electrode and a highly reflective, weakly transmissive electrode, with other OLED layers disposed between them. During operation in close proximity to an object, the object is illuminated by the device, while still allowing a user to see through the device. |

1. An organic light-emitting device comprising:
a flexible substrate; a highly-transparent electrode layer disposed over the substrate, the highly-transparent electrode layer having a peak transmittance of at least 90% in the 400-700 nm range; an emissive layer comprising an organic emissive material disposed over the highly-transparent electrode; and a highly-reflective, weakly-transmissive electrode layer disposed over the emissive layer, the highly-reflective, weakly-transmissive electrode having a minimum transmittance of not more than 20% and a peak reflectance of at least 50% in the 400-700 nm range. |
