摘要: An optical light redirecting film that can be made by microreplication, and that is suitable for use in an autostereoscopic backlight or display, includes opposed first and second structured surfaces. The first structured surface includes lenticular features and the second structured surface includes prismatic features. In some cases, at least a first prismatic feature has a first prism optical axis that is tilted relative to a thickness axis of the film perpendicular to the film plane. In some cases, at least a first lenticular feature has a first lenticular optical axis that is tilted relative to the thickness axis. In some cases, the film may have a central film caliper (thickness) at a central portion of the film and an edge film caliper at a first edge portion of the film, the central film caliper being greater than the edge film caliper.

摘要: Light directing film (100) is disclosed. The light directing film includes a structured major surface (110) that includes a plurality of microstructures (150) extending along a first direction (142) and a plurality of elevated portions (160) disposed on the plurality of microstructures. The number density of the elevated portions across the light directing film is D. Each elevated portion includes a leading edge (162) and a trailing edge (164) along the first direction. The light directing film can be divided into a plurality of same size and shape grid cells that form a continuous two-dimensional grid. The area of each grid cell is approximately 1/D. Each of at least 70% of the grid cells includes a single leading edge (162) of an elevated portion (160).
