Progress of Light Extraction Enhancement in Organic Light-Emitting Devices
Organic light emitting devices (OLEDs) have been used in flat-panel displays and lighting with a near-30-year development.OLEDs possess many advantages, such as full solid device, fast response, flexible display, and so on.As the application of phosphorescence material, the internal quantum efficiency of OLED has almost reached 100%, but its external quantum efficiency is still not very high due to the low light extraction efficiency.In this review the authors summarizes recent advances in light extraction techniques that have been developed to enhance the light extraction efficiency of OLEDs.
