摘要: We present a novel privacy filter film with transparent micro-cuboid arrays. The film, which does not include any opaque materials, rarely affects the normal transparency, whereas it obscures personal information by distorting paths of oblique light rays. effects cuboid size and gap between display are analyzed using ray-tracing program. analysis is consistent experimental results carried out poly-dimethylsiloxane (PDMS) (100 μm × 100 200 μm) arrays, fabricated lithography transfer molding.
