ABSTRACT:
Light redirecting film systems comprise a backlight having deformities that cause a majority of the light entering the input edge of the backlight to be emitted from a light output surface of the backlight. In close proximity to the light output surface is a light redirecting film that has a pattern of individual optical elements of well-defined shape to redistribute the light emitted by the light output surface toward a direction normal to the film.
