Samsung patents optical film with reflective pads for better light control
Samsung has filed a patent for an optical device that uses a multilayered film structure to manage how light passes through. The design includes a nanostructure layer with specific patterns and a reflective pad placed underneath inactive areas to bounce light back, using materials with different light-bending properties to improve performance.
In the filing’s own words
An optical apparatus includes a lower optical layer; a nanostructure layer disposed on the lower optical layer and having an active region and a non-active region; and a reflective pad disposed between the lower optical layer and the nanostructure layer to face the non-active region of the nanostructure layer, wherein the nanostructure layer includes a first dielectric patterned in the active region and unpatterned in the non-active region and a second dielectric filled between patterns of the first dielectric, and the first dielectric includes a first material and the second dielectric includes a second material different from the first material and having a different refractive index from a refractive index of the first material.
What exactly they claim (claim 1)
1. An optical apparatus comprising: a lower optical layer; a nanostructure layer disposed on the lower optical layer, the nanostructure layer comprising an active region and a non-active region; and a reflective pad disposed between the lower optical layer and the nanostructure layer to face the non-active region of the nanostructure layer, wherein the nanostructure layer comprises a first dielectric patterned in the active region and unpatterned in the non-active region and a second dielectric filled between patterns of the first dielectric, wherein the first dielectric comprises a first material and the second dielectric comprises a second material different from the first material and having a different refractive index from a refractive index of the first material, wherein an edge of the reflective pad proximate to the active region is disposed away from a boundary between the active region and the non-active region to form an offset away from the boundary, wherein a size of the reflective pad is smaller than a size of the non-active region.
