Abstract

Abstract : Hyperfluorescence™ (HF) combines TADF and fluorescence to provide narrow emission spectrum with four times higher emission efficiency than fluorescence. TADF acts as excitons generator and transfers excitons to fluorescence by Förster resonance energy transfer (FRET). HF also achieved long enough lifetime for AMOLED applications not only by durable molecules but also by controlling charge balances in Emissive Layer (EML). As the result of a collaboration with a display panel manufacture, the world's first HF display had been launched.
