Pixel mapping, arranging, and imaging for round and square-based micro lens arrays to achieve full volume 3D and multi-directional motion

摘要

A visual display assembly adapted for use as an anti-counterfeiting device on paper currency, product labels, and other objects. The assembly includes a film of transparent material including a first surface including an array of lenses and a second surface opposite the first surface. The assembly also includes a printed image proximate to the second surface. The printed image includes pixels of frames of one or more images interlaced relative to two orthogonal axes. The lenses of the array are nested in a plurality of parallel rows, and adjacent ones of the lenses in columns of the array are aligned to be in a single one of the rows with no offset of lenses in adjacent columns/rows. The lenses may be round-based lenses or are square-based lenses, and the lenses may be provided at 200 lenses per inch (LPI) or a higher LPI in both directions.

1. A visual display assembly useful as an anti-counterfeiting device, comprising:
a film of transparent material comprising a first surface including an array of lenses and a second surface opposite the first surface; and a printed image proximate to the second surface, the printed image comprising pixels of frames of one or more images interlaced relative to two orthogonal axes, wherein the printed image is adapted such that an image displayed from a normal POV includes a first set of symbols and a second set of symbols, wherein in an image displayed when the assembly is rotated from the normal POV about a first axis the first and second sets of symbols move in opposite directions, wherein the frames each comprises a different point of view (POV) of the one or more images, wherein the frames comprise frames providing at least three POVs along a first of the two orthogonal axes, and wherein the frames further comprise at least two additional POVs corresponding to each of the three POVs along the second of the two orthogonal axes.
