Integrating Out-Coupling and Light Management
The integration of a micro-structured optical film on the surface of the OLED enables more options than simply improving the efficiency of the device. By modifying the surface micro-structures , the direction and intensity of the light emitted by the OLED can be manipulated to create a variety of effects.
The out-coupling optical features can be modified to provide additional light redirection (at a slight loss to the out-coupling efficiency), so that the same film can for example make the OLED comply with anti-glare standards for office fittings, provide an asymmetric ‘wall washer’ light pattern, or give a ‘bat wing’ two beam strip emission useful in retail. In this way a single OLED design, coupled with different surface films, produces a range of lighting products.
