Abstract: An optical substrate having a structured light output surface that comprises rows of laterally arranged snaking, wavy or meandering longitudinal prism structures. The prism structures at the light output surface may be viewed as comprising rows of laterally meandering longitudinal prisms and/or sections of curved segments coupled end-to-end to form the overall meandering longitudinal prism structures. The laterally meandering rows of longitudinal prism structures are arranged in parallel laterally (side-by-side), defining parallel peaks and valleys (a facet is defined between each adjacent peak and valley). In one embodiment, the lateral waviness is regular with a constant or variable wavelength and/or wave amplitude (or extent of lateral deformation). The lateral waviness may generally follow a sinusoidal profile, or other curved profile. The structured light output surface may further include varying peak heights along each wavy prism structure and/or pre-defined structural irregularities such as non-facet flat section distributed in the structure surface.

Abstract: 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.

Abstract: A flexible light guide film having a light-adjusting structure in the form of a lenticular-like microstructure on the bottom side of the light guide film. The light guide film has a substrate layer supporting a layer light-adjusting structure, which is in the form of an array of longitudinal lenticular lenses laterally arranged in parallel. A prismatic-like microstructure may be provided on the top light emitting side of the light guide film. The light guide film is fabricated by a process involving coating/embossing of a roll of sheet material, in a roll-to-roll continuous process. Advantages includes significantly reducing the thickness of the light guide film, and the roll-to-roll fabrication process provides for more precise replication of the microstructures on the master mold or drum onto the surface of the light guide film, which in turn reduces the failure rate and manufacturing cost.
