Abstract: The present invention discloses a light directing film comprising a first structured major surface, a second major surface opposite to the first structured major surface and a reference plane between the first structured major surface and the second major surface, wherein the reference plane is substantially perpendicular to the thickness direction of the light directing film, wherein the first structured major surface comprises a first prism element and a second prism element extending substantially in a first direction, wherein a first ridge of the first prism element has a first height relative to the reference plane and a second ridge of the second prism element has a second height relative to the reference plane, wherein the first height of the first ridge of the first prism element varies along the first direction. Preferably, the maximum of the first height is larger than the maximum of the second height.

Abstract: An optical substrate has a structured surface that enhances brightness and reduces moire effect. The optical substrate has a three-dimensionally varying, structured light output surface that comprises an irregular prismatic structure. The irregular prismatic structure may be viewed as comprising longitudinal prism blocks or rows thereof, arranged laterally defining peaks and valleys. Adjacent peaks, adjacent valleys, and/or adjacent peak and valley may be parallel or non-parallel, in an orderly, semi-orderly, random, or quasi-random manner. The lateral adjacent peaks, adjacent valleys, and/or adjacent peak and valley are not parallel. The adjacent irregular prism blocks may be irregular longitudinal sections having the same length, or random or quasi-random irregular sections having different lengths. The facets of each prism block may be flat, or curved (convexly and/or concavely).
