Abstract
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.
