Abstract
A composite light guiding film module is disclosed, which includes: a light guiding film; a light diffusion structure comprising a plurality of micro concave lenses arranged in a first direction and a second direction to form a second dimensional array and the curvature of each concave lens and the junction of the concave lenses are not equal to zero; and a refraction element comprising at least one refraction structure, wherein light from a light source passes through the refraction element and is refracted to the light diffusion structure, and the light passing through the light diffusion structure is refracted into the light guiding film and then propagates in the light guiding film by total reflection.
