Abstract
A light enhancement film provided in the disclosure includes a substrate and an optical microstructure having a plurality of hexagonal cylindrical lenses inseparably arranged on a surface of the substrate in accordance with a honeycombed arrangement. Each of the hexagonal cylindrical lenses has different cross-sectional areas that are gradually narrowed from the surface of the substrate in a direction away from the substrate, and every two adjacent lenses have a gap therebetween. Furthermore, a display device having the light enhancement film is provided as well.
Claims19
A light enhancement film, comprising:
- a substrate;
- and
- an optical microstructure having a plurality of hexagonal cylindrical lenses inseparably arranged on a surface of the substrate in accordance with a honeycombed arrangement,
- wherein each of the hexagonal cylindrical lenses is gradually narrowed in girth from the substrate in a direction away from the substrate, and each of the hexagonal cylindrical lenses has a largest cross-sectional area on the surface of the substrate, and a smallest cross-sectional area furthest away from the substrate,
- wherein two corresponding surfaces of every two adjacent hexagonal cylindrical lenses are spaced by a gap between the two adjacent hexagonal cylindrical lenses.
A light enhancement film, comprising:
- a substrate having a surface;
- and
- an optical microstructure having a plurality of hexagonal cylindrical lenses arranged on the surface of the substrate, and every two adjacent hexagonal cylindrical lenses share a same edge,
- wherein each of the hexagonal cylindrical lenses has a largest cross-sectional area on the surface of the substrate.
