Abstract

A method of manufacturing a lenticular sheet having as its primary steps the provision of a substantially transparent substrate material; forming a plurality of lenses on a first side of the substrate; and shaping the substrate to correspond to a display area of a display device, wherein the plurality of lenses are angled to correspond to the pixel size and pitch of the display area. A display system is also disclosed, wherein the display systems generally includes a computer for processing, saving and playing at least one image; software for interlacing the image; software for processing slides and movies comprised of multiple images; a lenticular screen overlaid upon a video display device for viewing the interlaced images in three dimensions.

Claims

1. A method of producing a lenticular sheet having anisotropic optical properties comprising the steps of:

providing a substrate of transparent material having a first side and a second side and an index of refraction greater than one;

forming a plurality of lenses on the first side of the substrate; and

shaping the substrate to correspond to a display area of a video display device and for removable attachment to the video display device,

wherein the plurality of lenses are angled to correspond to the pixel size and pitch of the display area such that a two dimensional interlaced image may be viewed in three dimensions.

2. The method of claim 1, wherein the step of forming the plurality of lenses in pre-selected areas further comprises the steps of:

creating as cutting tool with a desired lens shape;

engraving a plate or cylinder with the cutting tool to form an inverse lens pattern in pre-selected areas;

using the engraved plate or cylinder in an casting process such that the substrate can be cast with the desired lens pattern.

3. The method of claim 2, wherein the step of engraving the plate or cylinder further comprises the steps of:

utilizing a computer to control and direct the direction and depth of the engraved lens pattern.
