Higher-efficiency Cost-effective OLEDs

Light and Charge Solutions is developing high-efficiency, long-lifetime, single-layer flexible organic light-emitting diodes (OLEDs) that could be cheaply and rapidly manufactured on large scale to meet DOE solid-state lighting targets.

Currently, the emphasis for commercial OLEDs has been on improving device efficiency by thermally depositing multiple materials, often more than 20 layers, to perform various functions. However, this creates significant manufacturing challenges for large-area lighting panels. Light and Charge’s solution is to replace the 20+ layers with a single robust material designed for high charge mobility and efficient electroluminescence.
