摘要:
A pixel structure for an electronic display, the pixel structure comprising a substrate, at least one LED emitter arranged on the substrate, and at least one wavelength conversion unit arranged on the substrate adjacent to the LED emitter. The LED emitter is configured to emit emission radiation, the emission radiation being within an emission wavelength range and emitted in one or multiple emission directions within a main emission plane. The wavelength conversion unit is configured to convert the emission radiation to converted radiation within a converted wavelength range, the converted wavelength range being different from the emission wavelength range. The converted radiation propagates from the wavelength conversion unit in a main conversion direction perpendicular to the main emission plane, the main conversion direction being, for example, a direction towards a user of an electronic device having an electronic display comprising at least one such pixel structure.
