Hyperfluorescence™ (HF) combines TADF and fluorescence to provide narrow emission spectrum with four times higher emission efficiency than fluorescence without using any rare metals. TADF acts as excitons generator and transfers excitons to fluorescence by Förster resonance energy transfer. Top emission devices of HF achieved wide CIE color space and are expected to achieve BT.2020 requirement. HF also had achieved long enough lifetime for AMOLED applications not only by stable molecules but also by controlling carrier balances in Emissive Layer.
