Abstract
A waveguide for use in a back lighting device includes a moth-eye structured surface. A back lighting system includes a lighting device, a display panel, and a waveguide for redirecting light generated by the light source toward the display panel. A first light-redirecting film, which can include a plurality of moth-eye structures, can be positioned between the waveguide and the display panel. The first light-redirecting film can also include a plurality of linear prisms. A second light-redirecting film is also provided that can include a plurality of moth-eye structures and a plurality of linear prisms. The second light-redirecting film can be positioned between the first light-redirecting film and the display panel. A diffuser can be positioned between the first light-redirecting film and the waveguide and/or between the second light-redirecting film and the display panel.
