Abstract
A field-of-view controlling arrangement for a display screen or window includes overlay in the form of a single sheet of light transmitting material having a plurality of parallel, spaced apart v-shaped grooves, or a plurality of polyhedral, conical, or frustoconical lens or prism structures, that serve to shift or expand the field-or-view of an image or scene viewed through the sheet. Any of the angled or curved surfaces of the resulting lens or prism structures may be treated to attenuate or scatter light, thereby providing a privacy screening effect with respect to a range of angles determined by the orientation of the treated surfaces.
