Abstract

Highlights An omnidirectional reflector (ODR) is proposed for improving the light extraction and mechanical flexibility of top-emission OLEDs. The proposed ODR, consisting of an Ag/SiO₂/Ta₂O₅ cylinder-embedded IZO mesh structure, exhibits remarkably high reflectance. Top-emission OLEDs with the proposed ODR exhibit a low turn-on voltage, high power efficiency, narrow FWHM, and exceptionally high mechanical durability.
