Title: Materials and architectures for efficient harvesting of singlet and triplet excitons for white light emitting OLEDs

Abstract

The present invention relates to organic light emitting devices (OLEDs), and more specifically to OLEDS that emit light using a combination of fluorescent emitters and phosphorescent emitters for the efficient utilization of all of the electrically generated excitons.
