    Abstract: This invention discloses a method of forming an uneven structure on a substrate. Use a hard tool to penetrate into a mold to cut a first trench and a second trench in an order on a surface of a mold, wherein the hard tool has a smoothly-curved shape such that the transverse width of each of the first trench and the second trench increases as the penetrating depth of the hard tool increases, wherein when each of the first trench and the second trench marches along a first direction, the penetrating depth of the hard tool is controlled by repeating moving the hard tool up and down to cut the mold such that the transverse width of each of the first trench and the second trench varies according to the controlled penetrating depth of the hard tool, wherein the first trench and the second trench completely overlap with each other with no space therebetween. Then, use the surface of the mold to emboss a thin film on a substrate.

    Abstract: The present invention discloses a light directing film comprising a first structured major surface, a second major surface opposite to the first structured major surface and a reference plane between the first structured major surface and the second major surface, wherein the reference plane is substantially perpendicular to the thickness direction of the light directing film, wherein the first structured major surface comprises a first prism element and a second prism element extending substantially in a first direction, wherein a first ridge of the first prism element has a first height relative to the reference plane and a second ridge of the second prism element has a second height relative to the reference plane, wherein the first height of the first ridge of the first prism element varies along the first direction. Preferably, the maximum of the first height is larger than the maximum of the second height.

    Abstract: This invention discloses a method of forming a prism sheet. The method comprises: providing a substrate having a major light input surface and a major light output surface opposite to the major light input surface; forming a prismatic structure on the major light output surface of the substrate; and forming an uneven structure on the major light input surface of the substrate, wherein forming the uneven structure on the major light input surface of the substrate comprises: providing a hard tool having a smoothly-curved shape such that the penetrating width of the hard tool increases as the penetrating depth of the hard tool increases; penetrating the hard tool into a mold and repeatedly moving the hard tool up and down to form a plurality of smoothly-curved concave shapes along a first path on the mold; and using the cut surface of the mold to emboss a thin film on the second path corresponding to the first path on the major light input surface of the substrate to form a plurality of convex shapes one-to-one corresponding to the plurality of smoothly-curved concave shapes on the second path on the major light input surface of the substrate; wherein the hard tool is not pulled away from the uncut surface of the mold so as to form the cut mold for embossing the thin film on the major light input surface of the substrate such that there is no space between each two adjacent convex shapes along the second path on the major light input surface of the substrate to maximize the uneven optical diffusing area on the second path on the major light input surface of the substrate.
