Enhancing the Light Extraction Efficiency in Micro‐Organic Light‐Emitting Diodes with Metalens

Advanced Photonics Research, 2021
Due to the total internal reflection caused by the mismatch of the refractive indices between organic layers and oxide layers within an organic light‐emitting diode (OLED), most of the light energy is trapped inside the device; if the size of an OLED is ...
