High-refractive-index capping layer improves top-light-emitting device performance

摘要

The performance of top-emitting organic light-emitting devices (TEOLEDs) was improved with capping layers having high refractive indices. The TEOLFD electroluminescence was examined with different capping materials on the same device structure. The luminance and power efficiency in the forward direction was improved significantly by using a high-refractive-index capping layer. (C) 2020 Optical Society of America
