ABSTRACT:
A method of inspecting a light-management film comprises reflecting light from an overhead light source off a first side of the light-management film and examining the light-management film for defects; directing transmission light from a backlight source through a second side of the light-management film to the first side and examining the light-management film for defects; reflecting light from the overhead light source off the second side of the light-management film and examining the light-management film for defects; directing transmission light from the backlight source through the first side of the light-management film to the second side and examining the light-management film for defects; and measuring a location of each of the examined defects in the light-management film.
