  • Electroluminescent device
    Patent number: 11362296
    Abstract: A device includes first and second electrodes that are at least partially transparent in a spectral domain; an electroluminescent layer that lies between the first and second electrodes suitable for emitting electromagnetic radiation in the spectral domain, the electromagnetic radiation being circularly polarized in a first polarization direction; a structured substrate, the first electrode lying between the structured substrate and the electroluminescent layer, the structured substrate including features that are reflective in the spectral domain, and that possess a hollow geometric shape configured so that electromagnetic radiation that passes through the first electrode is reflected from the reflective features while preserving the first polarization direction, a filler material that is transparent in the spectral domain and that is arranged to fill the reflective features so that the structured substrate has a planar surface.
    Type: Grant
