Abstract: An optical film comprises a transparent supporting substrate and a structuralized layer integrally formed on the supporting layer and having a plurality of light-concentrating units including design that varies in height along their length or varies in pitch of prism structure to overcome the optical defects (wet-out) of the optical film and to enhance the optical properties of the optical film.

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 translation: 具有结构化光输出表面的光学基底，其包括横排布置的蛇形，波浪形或弯曲纵向棱镜结构的行。 在光输出表面处的棱镜结构可以被看作包括横向曲折的纵向棱镜的行和/或端到端的弧形段的部分，以形成整个曲折的纵向棱镜结构。 纵向棱镜结构的横向曲折行横向（并排）平行排列，限定平行的峰和谷（在每个相邻的峰谷之间限定一个小面）。 在一个实施例中，横向波纹是规则的，具有恒定的或可变的波长和/或波幅（或横向变形的程度）。 横向波纹通常可以遵循正弦曲线或其它弯曲轮廓。 结构化光输出表面还可以包括沿着每个波浪棱镜结构的变化的峰高和/或预定义的结构不规则性，例如分布在结构表面中的非平面平坦部分。
