Abstract:
The invention relates to a light redirecting film comprising a thin optically transparent substrate having opposite sides, one side of the substrate substantially covered by elongated individual optical elements whose longest dimensions are substantially aligned in a lengthwise direction, wherein the shape of at least some of the optical elements have a visually significant difference, and wherein the layout of optical element shapes and locations is such that objectionable patterns are not visible in the film under standard LCD backlight viewing conditions.
