Abstract
The present invention relates inter alia to a color display comprising nanoparticles and color filters.
Claims23
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, but that 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.
A method for generating red emission which comprises incorporating a red light emitting semiconducting nanoparticle in combination with a red color filter in color displays comprising organic electroluminescent devices.
Layer comprising at least one red light emitting semiconducting nanoparticle and at least one red color filter.
