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.
Abstract:
A method for making a flexible OLED lighting device includes forming a plurality of OLED elements (14) on a flexible planar substrate, wherein at least one of the OLED elements (14) includes a continuous respective anode layer formed over the substrate (12, one or more organic light emitting materials formed over the anode layer, a cathode layer formed over the light emitting materials, and an encapsulating protective cover formed over the cathode layer. At least one of the OLED elements defines a continuous light region (26) on the substrate, wherein the substrate and combination of OLED elements define an active light area (30). The active light area is bendable from a flat planar configuration to a bend configuration having a design bending radius (32). The thickness of the cathode layer is formed between a minimum thickness value and a maximum thickness value as a function of the size of the active light area and the design bending radius. An OLED in accordance with these aspects is also provided.
