LIGHT-REDIRECTING OPTICAL STRUCTURE WITH LINEAR PRISMS, AND PROCESS FOR FORMING SAME

摘要

A light-redirecting optical structure includes a first side and a second side, the first side including plurality of linear prisms having a visibly random shaped surface on the prisms and a plurality of cross-cut prisms on first side which are oriented at an angle such that it is greater than zero degrees but less than 180 degrees. A backlight wedge includes a stepped structure on a bottom side that decreases in size traversing the wedge away from alight source which is positioned at an end and having a visibly random shaped surface on said wedge.
