Organic light-emitting diodes with enhanced out-coupling efficiency using high refractive index glass frit

摘要

We fabricated a novel type of substrate for Organic light-emitting diodes (OLEDs). It was fabricated by forming a flat layer using a high refractive index B_2O_3-SiO_2-Bi_2O_3 glass on the light diffusive glass substrate. By preventing total reflections, light out-coupling efficiency was improved more than 1.6 times higher.
