Hyperfluorescence (HF) is an emitting mechanism which combines TADF as an assistant dopant and fluorescence as a terminal emitter. RGB HF provided a wide color space which covered 95% of BT.2020 without sacrificing efficiency. This significant result was enabled by ultrahigh color purity by its narrow FWHM, smaller than 20 nm, in all RGB colors.
