Abstract
The present invention relates inter alia to a color display comprising nanoparticles and color filters.
Claims23
An electronic element comprising
- a) a pixelated organic electroluminescent device 100 comprising a first 101, a second 102, and a third 103 light emitting pixel that are identical, and are electronically controlled separately,
- b) a first color converter layer 201 disposed in the light output path 151 of the first pixel 101, wherein the color converter layer 201 comprises at least one light emitting semiconducting nanoparticle acting as first color converter;
- c) a first color filter layer 301 disposed in the light output path 251 of the first color converter layer 201 comprising a first color filter,
- and wherein the electronic element comprises scattering particles, which are SiO2, SnO2, CuO, CoO, Al2O3 TiO2, Fe2O3, Y2O3, ZnO, or MgO particles, or organic particles of polymerized polystyrene or polymerized PMMA, or inorganic hollow oxide particles, or sulfate particles or a combination thereof.
