Abstract
An article includes a first microstructured layer and a second microstructured layer. The first microstructured layer includes a plurality of first microstructures forming a plurality of first grooves therebetween. The second microstructured layer includes a plurality of second microstructures disposed adjacent to the plurality of first microstructures. The plurality of second microstructures forms a plurality of second grooves therebetween. The article further includes a light absorbing material disposed in at least each of the plurality of first grooves and each of the plurality of second grooves. The light absorbing material bonds the first microstructured layer to the second microstructured layer.
Claims19
An article comprising:
- a first microstructured layer comprising a plurality of first microstructures forming a plurality of first grooves therebetween;
- a second microstructured layer comprising a plurality of second microstructures disposed adjacent to the plurality of first microstructures, the plurality of second microstructures forming a plurality of second grooves therebetween;
- and
- a light absorbing material disposed in at least each of the plurality of first grooves and each of the plurality of second grooves, wherein the light absorbing material bonds the first microstructured layer to the second microstructured layer;
- wherein:
- the first microstructured layer further comprises a first base layer;
- the plurality of first microstructures is joined to the first base layer;
- and
- the plurality of first microstructures further defines a first structured surface and the first base layer defines a first non-structured surface opposite to the first structured surface.
A display comprising:
- a display panel configured to emit an image for viewing by a viewer, and an article having a first microstructured layer comprising a plurality of first microstructures forming a plurality of first grooves therebetween;
- a second microstructured layer comprising a plurality of second microstructures disposed adjacent to the plurality of first microstructures, the plurality of second microstructures forming a plurality of second grooves therebetween;
- and a light absorbing material disposed in at least each of the plurality of first grooves and each of the plurality of second grooves, wherein the light absorbing material bonds the first microstructured layer to the second microstructured layer;
- wherein:
- the first microstructured layer further comprises a first base layer;
- the plurality of first microstructures is joined to the first base layer;
- and the plurality of first microstructures further defines a first structured surface and the first base layer defines a first non-structured surface opposite to the first structured surface, disposed adjacent to the display panel.
