Sony patents nanostructure to boost color efficiency in displays
Sony describes a thin layer of tiny structures called a metasurface that works with light-emitting materials. The design uses specific shapes to match the frequency of the light, helping convert colors more efficiently.
In the filing’s own words
An emissive metasurface comprising a nanostructured dielectric component and an emissive system, wherein the nanostructured dielectric component comprises a plurality of metaatoms, and wherein the emissive system is configured to absorb and emit light in the visible range, and wherein the metaatoms are configured so that they resonantly match with the frequency of the light absorbed and emitted by the emissive system, is disclosed herein.
What exactly they claim (claim 1)
1. An emissive metasurface comprising a nanostructured dielectric component and an emissive system, wherein the nanostructured dielectric component comprises a plurality of metaatoms, and wherein the emissive system is configured to absorb and emit light in the visible range, and wherein the metaatoms are configured so that they resonantly match with the frequency of the light absorbed and emitted by the emissive system.
