OPTICAL STACK WITH ASYMMETRIC DIFFUSER

摘要

The present disclosure describes an optical stack that includes an asymmetric diffuser. As described herein, use of an asymmetric diffuser in an optical stack reduces undesirable defects in a display while maintaining optical gain and/or contrast of the display. The asymmetric diffuser is less diffusive along a first direction that is parallel with linearly extending structures of an associated light directing film.
