Beam splitting film, backlight module, and stereo display apparatus |
摘要 |
A beam splitting film includes a light transmissive plate, a plurality of cylindrical lenticular lenses, and a plurality of strip-shaped protrusion groups. The light transmissive plate has a first surface and a second surface. The cylindrical lenticular lenses are disposed on the first surface. The strip-shaped protrusion groups are disposed on the second surface. Each of the strip-shaped protrusion groups includes at least two strip-shaped protrusions. Each of the strip-shaped protrusion groups corresponds to one of the cylindrical lenticular lenses. A distance between an orthographic projection of a geometric center of each of the strip-shaped protrusion groups on the first surface and an orthographic projection of a geometric center of the corresponding cylindrical lenticular lens on the first surface is less than ten times of a distance between the geometric centers of two adjacent cylindrical lenticular lenses. A backlight module and a stereo display apparatus are also provided.
