*This abstract for appeared for patent application  number 18026806 Titled 'ORGANIC ELECTROLUMINESCENT DEVICE'

==Simplified Explanation==

The abstract describes an invention related to an organic electroluminescent device. This device includes a light-emitting layer B, which is made up of one or more sublayers. The sublayers of the light-emitting layer B contain certain materials, including at least one host material H, at least one phosphorescence material P, at least one small FWHM emitter S, and optionally at least one TADF material E. The small FWHM emitter S emits light with a specific property called full width at half maximum (FWHM), which is equal to or less than 0.25 eV.
