OPTICAL FILM

摘要

PROBLEM TO BE SOLVED: To meet a need for optical films that increase desirable characteristics of displays such as brightness and contrast while reducing defects that are distracting to the viewer.SOLUTION: Optical films having anti-Moire and anti-wetout features are described, along with systems and methods for making these optical films. A master used to make the optical films is formed by using a single axis actuator cutting along a trajectory that is out of plane with the surface of the master. Movement of the cutting tool along the trajectory cuts grooves having a variable depth and a variable pitch into the surface. Prisms formed from the master have a variable depth and a variable height, thereby providing anti-wet-out and anti-Moire features.
