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.
Claims43
An overlay, comprising:
- a single light-transmitting sheet including a plurality of parallel grooves defined by sets of intersecting angled surfaces,
- wherein the grooves are spaced apart from each other.
An overlay, comprising a single light-transmitting sheet including a plurality of polyhedral structures.
An overlay, comprising a single light-transmitting sheet including a plurality of frustoconical structures.
An overlay, comprising a single light-transmitting sheet including a plurality of conical structures arranged to control a field-of-view for an image or scene viewed through the overlay.
An overlay, comprising a single light-transmitting sheet including a plurality of interlocking solids having polygonal bases.
A field-of-view controlling arrangement, comprising:
- a single light-transmitting sheet arranged to expand or shift portions of a field-of-view for an image or scene viewed through the sheet,
- wherein the sheet includes a plurality of parallel grooves defined by sets of intersecting angled surfaces, and
- wherein the grooves are spaced apart from each other.
A field-of-view controlling arrangement, comprising a single light-transmitting sheet including a plurality of polyhedral structures arranged to expand, shift, or restrict a field-of-view for an image or scene viewed through the sheet.
A field-of-view controlling arrangement, comprising a single light-transmitting sheet including a plurality of frustoconical structures arranged to expand, shift, or restrict a field-of-view for an image or scene viewed through the sheet.
A field-of-view controlling arrangement, comprising a single light-transmitting sheet including a plurality of conical structures arranged to expand, shift, or restrict a field-of-view for an image or scene viewed through the sheet.
