Abstract
Embodiments of the present disclosure include organic light emitting diode (OLED) devices having hollow objects configured to scatter otherwise trapped light out of the device, thereby improving the performance of the device. The hollow objects are dispersed in one or more organic layers of the OLED device. The hollow objects may have a similar refractive index to that of air, such that visible light emitted by the emissive layer may contact the hollow objects in the OLED device and may be scattered out of the device. In some embodiments, the hollow objects may be spherical or tubular, and may be sized to be larger than the visible light wavelength spectrum.
