Abstract— A unique roll‐to‐roll mass‐producible high‐transmission wide‐angle diffuser (WAD™) film for use in LCD backlights is reported. WAD™ diffuser films include optical structures that efficiently manage forward light scattering and significantly reduces backward light scattering. WAD™ technology facilitates backlights with significantly higher brightness and thinner backlight profiles.
