Light control sheet

A light control sheet having opposing first and second major faces, the first and second major faces being substantially parallel to one another and connected by a perimeter edge, and the light control sheet having a plurality of optically transmissive optical elements, each pair of adjacent optically transmissive optical elements forming a generally planar surface interface therebetween resulting in an internal array of generally planar surface interfaces, wherein

• each generally planar surface interface extends along a longitudinal axis that is parallel to the opposing first and second major faces from a first location on the perimeter edge to an opposite second location on the perimeter edge, and extends along a transmission axis from the first major face to the second major face, wherein the longitudinal axis is parallel to the longitudinal axis of other disruptive optical interfaces, and the transmission axis is not perpendicular to the first and second major faces of the light control sheet, and
• the light control sheet is light transmissive such that an image incident to one of the major faces is visible from the other major faces within a field of view which is perpendicular to the major faces but wherein each generally planar surface interface between the corresponding pair of adjacent optically transmissive optical elements randomly redirects light so that the image is blurred outside the field of view.
