    • Diffusers including of a plurality of protruded structures with each structure containing multiple rugged facets are disclosed. The diffuser may be fabricated by coating a mixture of materials on a carrier film, the mixture of materials including at least a first material that polymerizes upon irradiation and at least a second material that is incompatible with the first material in polymerized form, then selectively irradiating the mixture of materials to polymerize a portion of the mixture of materials to form polymerized structures, and finally removing that part of the mixture of materials not forming part of the structures. A transparent material may be coated over the structures. The overcoat material may further contain scattering elements such as glass beads or polymeric particles.
    • 公开了包括多个突出结构的扩散器,每个结构包含多个坚固小面。 扩散器可以通过在载体膜上涂覆材料的混合物来制造,所述材料的混合物至少包括在照射时聚合的第一材料和至少第二种与聚合形式的第一材料不相容的材料,然后选择性地照射 聚合材料混合物的一部分以形成聚合结构的材料的混合物,最后除去不形成结构部分的材料混合物的那部分。 可以在结构上涂覆透明材料。 外涂层材料可以进一步包含散射元件,例如玻璃珠或聚合物颗粒。
