ABSTRACT:
A method for fabricating a device for displaying an interlaced image. The method includes providing a film of transparent material and creating a lens array in the film by forming parallel lens sets on a first side of the film, and then bonding an interlaced image including sets of elongate image elements to a second side of the film. Each of the lens sets is configured with lenses for focusing light from one of the image elements in a particular paired set of image elements rather than all the elements as with lenticular material. The bonding of the interlaced image to the film may include printing the interlaced image directly onto the second side with the printing facilitated by the small lens array thickness. Lens array creating includes embossing the lens sets into the film with a flat die or cylinder/roller engraved with a reverse image of the lens array.
