摘要： 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.

摘要： An optical substrate having a structured prismatic surface and an opposing structured lenticular surface. The structured lenticular surface includes shallow-curved lens structures. Adjacent shallow-curved lens structure may be continuous or contiguous, or separated by a constant or variable spacing. The lens structure may have a longitudinal structure with a uniform or varying cross section. The lenticular lenses may have a laterally meandering structure. Sections of adjacent straight or meandering lenticular lenses may intersect or partially or completely overlap each other. The lenticular lenses may be in the form of discontinuous lenticular segments. The lenticular segments may have regular, symmetrical shapes, or irregular, asymmetrical shapes, which may be intersecting or overlapping, and may be textured. The lens structure may be provided with isolated ripples, in the form of a single knot, or a series of knots.
